There is an exact dimension specification for each tire size as determined by the tire size calculator and the chart that I referenced. I also understand that there are tolerances to the manufacturing process. The recommended (but not codified) tolerance is +/-3 percent, which as Samurai Edge said, is minimal. Multiple tread depth readings must be taken around the tire to determine wear. However, the correct measurement to use would be at the lowest point. (A tire down to the wear bar at any point is a tire that needs replacing, even though at another point, the wear bar is not showing.)

Tires of the same size (i.e. P245/60R18), no matter the brand, have the same diameter. The only way to determine the wear on a tire is by using a tread depth gauge. Here is a link to a page showing the specs for each tire size: TIRE SIZE GUIDE - TIRE DIAMETER, WIDTH, AND MORE. – PREMIER TIRES & WHEELS

Here is a youtube video that I found and if you skip to 4:28, you will find the 2024 Ford Edge: Now, this video has stupid AI narration and spelling errors, but is this a widely-held opinion? I love my Edge and plan to keep it until Hell freezes over.

On an AWD vehicle, some recommend the replacement of all four tires as it is critical to prevent damage to the rear differential. Closely maintaining the rear differential by having tires with the tread depth and regular fluid changes may avoid large repair bills. I am not sure what you mean by checking "the diameter of the new versus the originals and they are almost the same." Do you have a tread depth gauge? Using a tread depth gauge is the only way to measure the diameter of a tire that is not new. Did the tire dealer measure the tread depth of the two remaining tires? Yes, mixing of symmetric and asymmetric tires may also cause a problem with rotating the tires. I am surprised that the tire dealer even sold you the asymmetric tires (it must have been that it was the only type that was in stock - tire dealers do this - I used to be a tire store manager.) You would always want the asymmetrical tires on the rear because of the different handling properties, tread pattern and speed rating difference, but rotating tires is critical for an AWD.

Yes, your car IS a computer on wheels. The more things that are electronically controlled are also more things that can glitch. I used to work for a manufacturer of coffee brewers for convenience stores and the first thing we told customers with machine problems was to turn off and turn back on the machine.

Was your transmission serviced (flushed or drained and refill?)

Not sure why the link does not work for me. Maybe it is being blocked by Ghostery? I found it on Amazon: Amazon.com: Dynamic Flowing Car Trunk Light Strip, Trunk Led Light Strip，Led Strip Lights for Car Trunk Cargo Area or Interior Illumination Decoration (White,Full Circle 4 m/157 in) : Automotive. It is available for the top half or whole circumference. It is hard wired in through the rear lamp. This one is available in blue, purple, and warm or cool white.

Please check the link. I cannot get it to work.

I found two that are available. Ebay has one for $149 including shipping. 2007-2010 Ford Edge Rear Bumper Parking Sensor Wire Harness 7T4T-14N139 | eBay The other is from a salvage yard in San Fernando, CA for $149 (plus shipping?) FORD EDGE WIRE HARNESS REAR BUMPER PDC 2007 2008 2009 2010 INCLUDES SENSORS You might check your local salvage yards as this part fits all models from 2007 to 2010.

Does the Edge have an undersized alternator? I do drive many short distances, but it only takes a couple of trips for the start-stop (yes, I know everyone hates that) to stop working and in about ten days, I get the battery saver message and all but the driver's door cannot be locked/unlocked from the outside. I have had the battery checked and replaced, but the problem did not go away. I bought an AC battery charger (Battery Tender) that plugs into my cigarette plug. I keep it on the charger when I am at home. It is a pain since I have to roll down a window to plug it in, but I do not want to get stuck somewhere. I have the first electric Edge!

There are many grills available online. Search "Ford Edge Grill Black." I have attached a picture of one that is available.

I also was a tire salesperson in Southern California in the early 80's (those days are long gone - sigh.) There was this one customer complaining about tramlining (that term had not been invented then.) The tires were Goodyear Custom Polysteels. There were seven circular and uniform grooves on the tires. We thought that the grooves were interlining with the grooves on the freeway. We changed them out with the Arrivas and the squirming went away. I would have thought that since that time, the manufacturers would have been able to resolve the issue. In doing research, I found that it may be also caused by low profile tires, larger than OEM tires or wheels, or tires with reinforced sidewalls (which are very rare - most tires have a single-ply casing with two steel belts overlaid on the carcass.) I found some tires which do not have circular and uniform groves: Nexen N Blue 4Season2, Kumho Solus 4S, Nitto Motivo 365, Pirelli Scorpion Weatheractive, Michelin Crossclimate2 and Toyo Proxes STIII. I suppose the best way to diagnose if your problem is being caused by your tires/wheels is to find a buddy with a same generation Edge with the OEM wheels and tire size, mount them on your Edge and see if the tramlining goes away.

You need a T155/70R18 sized tire, a wheel (KT4Z1015A) which is sized 18" x 4", 5 Lug, 4.25" Bolt Pattern, and the jack with components. From the attached diagram, you only need the jack, mounting stud, wing nut and wrench so that it is secured in the well. The mini spare became an option around the 2021 model year. For some reason, Ford included the mini spare with some new Edges, but charged $100 (see the attached window sticker.) It was not included at all on others. I would search your local salvage yards for these items. Be careful that you find the 18-inch tire and wheel, not the 17-inch combination. Since the model refresh in 2015, these items have remained the same, so there should be plenty of availability. windowsticker.pdf

I am old fashioned. I know manufacturing techniques are better today, but when I bought my Edge straight from the dealer, I had the engine oil changed at 1,000 miles and the transmission fluid completely flushed at 15,000 miles (my Edge is not AWD so no differential or I would have also changed it early.)

There are thousands of listings for S154D Rear-End Differentials on ebay. Most are remanufactured in China.
