Wider tire than stock on 21" rims

Recommended Posts

Anyone tried 295/35 21??

Wondering if they're too wide.  Doesn't seem to be an enormous amount of space on rears.. haven't even looked at front yet.

As I remember, someone here at the forum did put 295/35 R21 tires on his OEM rims and reported that they fit. There was nothing said about long term use . Although the  295/35 R21tires do fit they are not recommended for use by the manufacture on 9 inch wide rims,  like the OEM 21 inch ones on Sports.The 295/35 R21 tire will be 1/2 inch wider on the inside and outside for a total of one inch wider overall, same sidewall and overall hight and diameter as the 265/40 R21 OEM tire.

Thanks for the reply.  I saw the post you're referring to after a deeper dig on the forum.  I like the way they look and am ordering some.  I'll post after a few thousand miles and let everyone know how they're holding up.  

 

Just traded my Focus ST in on the Edge ST and so far I like it.  Not quite as fun to drive but a hell of a lot easier to enter and exit (I'm 67).

 

Ordered lowering springs, having cat back dual  custom exhaust (Flowmaster 50) done next week and will post photos when all is complete.

 

Thanks again for the response and Happy Thanksgiving to all.

I am interested in the results after it is lowered with the 295s all around.  What is the diameter of your exhaust  system?

Gonna try to go 3", but may have to settle for 2.5. Having it done Tuesday, hopefully. Will post back then.

Did resonator delete and left factory muffler. No drone, but sound still isn't quite where I want it.  Will post back with update after I choose mufflers and get them installed. Kept factory pipe.

Sorry this took so damn long.  I'm. OTR driver and had to do all mods in increments and just got around to tires.  Here are pics 295/35 21 Continental Extreme Contacts

Decent shot of tire width and the left side of exhaust tips.  Getting all of the sound past that bumper with the tips eliminated 99% of thee offensive drone.

Looking good ! Thanks for the photos ;).   How do you like the wider tires so far? Any improvements or problems?

Nope!  Love them... Maybe a tiny bit less on fuel mileage, but did tires and grill shutter delete around same time so it's hard to say. Did a thousand miles over the last 4 days and got 28.5 as opposed to 30.2 last time I did exact same trip.

Tire pressures set the same?

It may sound irrelevant but a softer sidewall (whether by tire design or reduced pressure) causes more rolling resistance which can translate to lower MPG.

Also did you correct for ANY difference in circumference in Forscan? 

(You may have said above, no time to read back right now)

Tire pressure is the same and didn't change anything in Forscan as they are the exact same height as original tires.  They are an inch wider and I know that could have an impact.

I believe the 295 tires are 1.2 inch wider than the 265 . Thats great that they are working so well for you.

Wonder what effect they have on the AdvanceTrec system? 

 

I read on the F150 forum when they used wider tires the roll stability (they referred to it as the Traction Control System) kicked in, when driving over 35 mph and going around curves. He found he could reduce it by slowing down on tight curves.
