Winter Tire Size Question

[Grimmer]

Look up your car on TireRack.com. I spoke with their customer service because of some discrepancies between their recommendation about fit and the rim manufacturer's recommendations. He described their process and they are very judicious about ensuring that their "will it fit my car" recommendations are correct. If they don't show 17" as available for your car, then they will not fit. You will also need to know what the setback is on the rims you consider purchasing.

My GT came with 19" and I switched to the 18" narrower and taller for winter tires. One important consideration, in addition to the rim size and setback, is to get the outer diameter/circumference of the two different tire sizes to be the same or it will mess up your speedometer. There are tire size vs circumference calculators on the internet. And I believe that TireRack.com has a fairly decent rim buying guide.

For the 2016 model year, both the GT and EcoBoost came with 18" minimum rims. The clearance between the brake calipers and the 18" rims is very small, no way a 17" rim would fit that model year. I don't know if they changed for the 2018 MY. Do they have specific brake calipers for the EcoBoost vs GT? If not, they you can't go less than the GT anyway.

Just spoke to tire rack who said that size fits fine. 17" was the first thing that came up but they recommended 235/55R17. I asked if the 225/60R17 would work and they said it's fine.

Good morning everyone,

Looking to buy some winter tires for my 2018 Mustang. I found a guy online who is selling X-Ice 3's barely used, but I am unsure if the sizing will work. They are 225/60 R17's. Does anyone know if these will work on the car or if there will be any issues? Hoping to avoid buying the wrong set of tires.

I live in Toronto so it does get pretty snowy here during the winter but the streets are normally plowed. Periodic heavy snow or ice patches are generally what I run into.

Any input is greatly appreciated.

If your Ecoboost 'stang is a Performance Package car, then 18" is the minimum rim size you can use. Otherwise, 17" tires should be just fine. Note: factory 17" tire size is 235/55R17. I'd be worried about loading, personally, with the smaller tread width (might want to check the specs of the tires and make sure that they're ok with the weight of the car + 4 passengers). I think you'll also find that 7" is going to be the minimum width of the wheels that you can get for the Mustang. I'd make sure that a 225 width tire can be fitted safely to a 7" rim.
