Hello Waldo: Very interesting subject, and very helpful the link you provided; thank you. I'll have some more homework to do on the side for my own knowledge. Thanks again to all constructive and instructive comments, opinions and suggestions.

Thank you WWWPerfA for the links provided; really helpful! Thank you all.

Hi folks: I was browsing around several other fora, and also did some search to see where it was more appropriate to post this info/question. I decided to post it here because I'm more familiar with this forum, but I'm afraid that many other year model owners with the same interest may be left out. Moderators please feel free to move this post/thread to a more suitable forum if you believe so. Have you folks been aware/noticed that Mobil 1 is no longer meeting Ford specification WSS-M2C930-A? I noticed they changed the Mobil 1 engine filter packaging to a smaller filter size (ok?). I also noticed they changed the motor oil container to a bigger size (that's a better size!). But then I noticed that the same motor oil I've always bought to change it in my 2011 Edge SEL (Mobil 1 5W-20 Advanced Synthetic Motor Oil) was no longer listed among the approved oils in my local store. So, I checked the new 4.73L oil package label and, fair enough, Ford spec WSS-M2C930-A is not listed in the new package label of the same motor oil as "Meets or exceeds the requirements of: -Ford WSS-M2C9XX-X." I double checked my 2011 Edge Owner's Guide: Maintenance and Specifications, page 329 reads: "...or equivalent SAE 5W-20 oil meeting Ford specification WSS-M2C930-A". It was listed as meeting specs in the previous 4.4L package label... My questions to you folks: - Is anybody aware of this change, Mobil 1 no longer meeting Ford spec WSS-M2C930-A? - If anyone knew, out of my curiosity, can I know why? (did Ford miss the deadline to submit the required paperwork, did the specs for the 2011 Edge change, did Mobil 1 change oil formulation and Ford didn't accept it...?) - Most importantly: can somebody pitch in his opinion regarding if it's still safe for us to continue using this oil in our vehicles despite no longer meeting Ford specs for our vehicles? Aloud thoughts and comments are all welcome and always very appreciated in advance.

Thanks Omar for sharing your experience. My situation was different because I'd have to buy them. But then if they don't fit I'm not sure I'm going to get my money back when I resale them. I'll pass. Thanks again.

Todd, Snoking, thanks for your comments; we all know studs and chains provide better traction than bare tires. I'm making another edit in my previous comments to clarify I'm talking about studdless and chainless tires. Sorry for getting you confused. Akirby, I honestly don't know where you took that I obviously know more than you folks do... I have shown in all my comments that I do NOT know about this matter, I have clearly explained my thoughts, and I have even said or written SORRY after realizing I have drawn wrong conclusions. I think I've been modest and honest... As a matter of fact, I wouldn't asked questions if I would have known better than you. But you are a moderator, so, you have all rights to insult a person who is making genuine questions, or even banning me for no real reasons if you like. Waldo, thank YOU VERY much for your time, understanding of my questions, for your VERY thorough explanation of the matter, and your constructive comments. I've understood perfectly and learned something else tonight and I now know better, thanks again. Your suggestion about lowering the tire pressure is a great one (I never thought about that before). My car is calling for 35 psi; I'll probably lower the pressure to 32 psi. Hopefully that'll improve a little bit the ice traction without wearing out too prematurely the outside patch edges, and hopefully that lower pressure won't be enough to trigger the TPMS warning either. I'm backing out of my search for wider tires as there'll be no gain for my purpose. Thanks again. If I could steal a little bit more of your time and knowledge, I would like to ask you a related question, although a little bit off the main topic (Akirby you can move this post to a more appropriate thread, or delete it all together if you find it out of context). Waldo: thinking back, I think that part of the reason I tent to believe that wider tires have better traction may have come from seeing some sport cars and actual racing cars having wider tires on the driving wheels (engine driven wheels). As Snoking mentioned it above, Camaros came to mind, also Corvettes, and obviously real racing cars. Up to date, I thought the reason they have wider tires was to increase the traction and have a faster take off (in 0-20 mph, or something like that), and I thought that will also serve for a faster braking/stopping. So, if wider tires not necessarily provide better traction, why some of those cars have wider engine/transmission-driven wheels? Again, I can start a new thread on this subject if this post is not appropriate, or PM you directly, or you can PM your answer. I want to thank everyone for your instructive and constructive comments.

Yes, something similar in my case, the price has gone up a little bit ($3 ea). Again, it's not so much about the little money but about charging for a service not provided or not done, even though after I mentioned. He refuses to remove that charge... Guess he's not taking my business.

Hello Omar: Thanks for your clarification. I went to the dealer and they couldn't tell either. It's very hard to know. I don't know how you tried it before but it seems to be a "try and error" thing. My problem is that I don't want to take the risk of buying those wheels to find out they don't fit properly. Thanks again.

Hi folks: I think you all are either missing my point or I may have missed expressing myself correctly. I'll try to write it simpler: Firstly, Snoking, I'm talking about winter tires only; the Camaro's example might be out of context; sorry. Secondly, Akirby, that's exactly what I'm saying (or have been trying to say): I'm talking about winter tires only (I am referring to ice performance). So, you and I are talking about the same thing, therefore I'm correct: winter (ice) tires. Thirdly, Todd, with all my respect to you too, if on my same vehicle with the exact same winter tire brand and type Continental VikingContact 7 the size 255/60R18 (wider) does not provide a slight better performance on ice than a size 245/60R18 (narrower), ...physics are... I don't know. Again, with all my respect to all, I thought you folks realized I have to be talking about the exact same tire brand and tire type on the same vehicle for comparison, otherwise it'd have been like comparing apples and oranges. Sorry if I didn't express correctly myself, or if I wasn't so specific explaining that (from the mechanical point of view, I'm not a mechanic) I am looking for the wider winter tire that could fit my own vehicle. I know my stock is 245/60R18, but I do NOT know how much wider, the maximum width I can mount tires on my 18" stock rim without compromising safety (without rubbing any steering components inside the wheel well of my vehicle, etc). I knew (again sorry for having not been so specific), that I was logically referring to the exact same winter tire brand and type. Absolutely everything is the same: vehicle, tire brand, tire type, tire ratio (60R), tire rim (18"), the absolutely only difference is the tire width (255mm vs 245mm). If 255mm width does not provide more ice grip, friction, resistance than 245mm width, ...I may have to go back to engineering school then. Hope you all now understand the reason of my question, and also my rationale. So, from my two-week research (including websites provided by members here, thank you all again), I think I can safely go in my vehicle stock/OEM rims up to 265/60R18, but that size is very difficult to find (probably not made). Therefore, looking for a slight improvement on ice performance (using the same tire brand and type), I'm thinking to go with 255/60R18, which is commonly available. I believe those 10mm wider will provide a slight increase in contact surface, and therefore a slight increase in friction and resistance on ice-covered pavement. I DO appreciate all your time, and also DO thank you all for your thoughts. I'm still open for more comments if mine didn't clarify enough, ...or if you still think I'm wrong. EDIT: I reread ALL your comments above (thanks again) and rethought myself. I think I got it now: 10mm wider in tire size not necessarily translates in wider contact patch because, if I understand correctly, that size refers to wall-to-wall width (not specifically to contact patch width). Based on all I explained above in this post, and also based on manufacturer descriptions, independent scores, specialized reports and consumer reviews I've now narrowed my search to two studdless winter tire brands and types: Continental VikingContact 7 and/or Bridgestone Blizzak DM V2. I now have to find out if the size width difference actually translates in different contact patch width as well, or not. I will try to find out that info, but meanwhile I'll greatly appreciate it if somebody could send me in the right direction to find that out. In summary (all studdless tires, please): Contact patches for: - Continental VikingContact 7: 245/60R18 and 255/60R18 - Bridgestone Blizzak DM V2: 245/60R18 and 255/60R18 Again, any info source is greatly appreciated before hand. Thank you all.

Waldo: first of all THANK YOU very much for your thoughtful comments in your previous reply. I forgot to thank you before; sorry (somehow I missed your reply). Secondly, lol, ...I have a short answer to give you lol. ...Nooo, just kidding. Seriously: I don't know which country, state, province, city or general area you live in, and how familiar you are driving on snow and/or ice, but I'll give you the long answer. Please bear with me: I live in the city. When the snow falls (usually for a few hours), the city plows take good care of the snow right after it falls; therefore, I hardly ever really drive on snow, very seldom, and when so, I consider myself a good snow driver as, so far, I've been able to control my vehicle on snow 99% of the time (no concerns for me driving on snow). ❄️ However, as the city plows don't remove 100% of the fallen snow from the asphalt, the remaining snow gets compacted eventually becoming ice, and usually stays on the payment for several days, along with the cycling process of thawing during sunny days and freezing up to black ice once the sun is gone. Therefore, I much more often drive on ice-covered asphalt than on snow-covered asphalt. On ice, ...there is never 100% control of your vehicle. Ice is ice. I guess you now know where I'm going... Generally, the wider the tires, the more contact patch (contact area), more resistance and more friction I'll have. Therefore, lesser chances to slide, skit on the ice, and if so, it should be for a shorter time (compared with narrower tires of the same kind). ⛸️ ...And wider looks better (to me ) This is my rationale. I know the rationale of "narrower tires for snow" has been out there for a long while 🌨️. I'm not totally convinced..., but I won't argue. Again, snow is not my concern; ice is. Hope having answered your question.

I guess this supplier doesn't know well what/how is doing. Below is his response: "The valve stem service is a required part of our tire changeover and installation package. It is not optional and (charges) cannot be removed." (the brackets are mine). I think I'm going back to my previous service supplier. I don't think they charged me for that before, but I'm going to double check this time. Thanks everybody.

Hello folks: Thanks for making my question not an stupid one. That's what I thought as well. I remember replacing the tires before when I first got the Edge and I knew nothing about TPMSs (first car with TPMS for me), and I requested the shop to use short-stem valves when replacing the tires (as they normally put new valve stems when replacing regular tires). They say "OK" (without looking at my wheels, just complacent with my request), but later they came out of the shop and asked me if I REALLY wanted the valve stems replaced because... they have TPMSs. I said "Of course not!" lol The reason for my question now in this thread it's because I'm ordering a new set of winter tires (from different service provider). The guy giving me the estimate included a charge for "Passenger Valve Stem Service", as well as "Performance Passenger Road Hazard Warranty", among other charges. I kindly asked him to take off the valve stem charges because my tires have TPMS (...I learned that lol) and I'm not going to replace them yet. Here is his response: "Valve stem service is required since we need to remove the valve stem and TPMS sensor from your wheel to change the tires. It covers any shop materials used (new stems, covers, or gaskets) along with the additional labour of moving your TPMS units." I'm confused... He said they "...need to remove the valve stem and TPMS sensor..." This is an ISO-Certified tire dealer in the region (not a guy in the backyard...). Could you folks please clarify for me if he's right? Or I should keep arguing..? I know there's not a lot of money to be charged for that service..., but I just don't like to pay for services not needed or not received. Thanks in advance for your thoughts and suggestions.

Hi Omar: Thanks for your comment (always very appreciated). I assume when you say "rubbing" means a significant rubbing that will not go away soon with wear and tear. So basically, not an easy way to make it fit, I assume. Too bad Thanks again.

Hello folks: This may be kind of stupid question for many of you, but I don't know and need to ask: When replacing the tires (like putting a new set of tires) on the rims, are the TPMS valves removed as part of the procedure? I said it's kind of stupid question because for comparison I know the valve stems have to be lose and removed when changing the inner tubs in bicycle wheels lol, but the cars no longer used inner tubes (tires are now tubeless ;), do the TPMS valves/stems still need to be removed anyways when replacing the tires on the rims? Sorry if my question is too stupid... I just don't really know, ...and would really want to know for sure. Thank you.

Hello folks: I need your help to determine if I pull the trigger on this sale to fit my 2011 Edge SEL (FWD): A set of 2015 Explorer Sport wheels & tires with TPS sensors is up for sale. Bolt pattern is (5 x 4.5 ) or (5x 114.3) from what I understand on google will fit 2012 to current 2021 Explorers, and I believe it's the same bolt pattern for the 2011 Edge. I assume the offset is different but I don't know if it's still safely acceptable... Tire size is 255/50R20 which I now know will fit the 2011 Edge (thanks to Xtra and other folks for links provided in another thread). Do you folks know if this set will fit the 2011 Edge SEL? Please let me know. Thanks in advance. Photo "borrowed" from the sale ad:

Hello Xtra and all: Xtra thank you, thank you very much! The links you gave me have definitively helped A LOT! I was almost settled for 255/60R18 (I'm negotiating a set of Nokian Hakka R3), but a sale just came up in Kijiji which made me post a different question in this forum. Again, I REALLY thank you, very helpful all those links.
