Mach-E tires are quite narrow, on lower trims its 225 wide and 245 on the GT Performance Edition. Does anyone think they could be much wider and can recommend specific sizes to go with? Along with how range and performance would be impacted? I suspect the narrow size was to improve range.

Mach-E Extended Range
  • 225/60R18
  • 225/55R19
Mach-E Extended Range AWD
  • 225/55R18
  • 225/55R19

I'm getting a GT, and will put 255's on it. Range is not important to me, and I want max cornering gas. Looking at the Michelin Crosstour 2 for winter, and Bridgestone RE71R's for summer.
I bet that will hold true for a larger portion of GT owners than others. Are you planning to get in some track time?

Interestingly, the Mach-E 1400 race car has 225's up front. I was expecting it to be wider but good to see Ford kept it like the production models.

Yes, I'll be competing with it. Horsepower is for straights, torque is for corners.

Only reason I've ever had to go wider was issue with road rash on rims. The Tesla tires are the first I've ever had where the rim sticks out past the tire and wheels get scraped all the time. Road rash is big complaint of first time Model 3 buyers.

Kyle on OutofSpec noted that while the MachE tires were narrow the did cover extend over the wheel.

If Ford says accel and braking distances work with the OEM size, I would not change it for a bigger footprint tire as that will cost efficiency and range.

1/4 mile times won't be impressive...0-60 will be slightly better. But neither interests me...corner exit speed does.
GCR did note that "on the slalom course, the Mach-E cornered flat and remained balanced." and "on every turn, heard the rear tires squealing well before the fronts—perhaps reflecting the car’s more powerful rear motor and rear-wheel-drive bias" It will be great to see how you can improve on that.

I'm considering getting wider tires for traction after I make sure that there isn't a huge range penalty. I'm also not a fan of how skinny the stock tires look.

Because the wheels are 24” high, they look narrower than they actually are. They are almost 9” wide.

On second thought, I'll probably try to stuff 265mm Michelin Pilot Sport EV tires into the wheel wells, on 9.5"x20" rims. However, the Pirellis that come on the GTPE are bespoke, so they may be the way to go, but I'd bump 'em up to 265mm. The Michelins won't be available until this fall, but they promise 30% greater efficiency. They're built specifically for ev sports cars, with stiffer sidewalls, harder center tread and softer outer tread. They're also designed to withstand an ev's greater weight and torque. We'll see...

I’m going to go with 245/50-19s since they are the same 28.7” overall diameter as the OEM 225/55-19s. Will probably get Michelin Pilot Sport AS4s since they have grip on par with most of the better summer tire options while still offering good cold weather traction.

We ordered our XR AWD with the summer tire option but I assume they’ll still be 225/55s, so far I haven’t found any info on what brand/model the optional summer tires are.

Will 245’s fit on the stock rims? I have been trying to answer this question since we bought the car. I don’t like 225 tires on any car. Just doesn’t feel stable.

Yes. The 245/50-19 Michelin Pilot Sport 4 AS tires we’re going to get fit rim widths from 7-8.5” according to the specs at TireRack.com. Stock Premium wheels are 19”x7”. They are also the same 28.7” overall diameter as the OEM 225/55-19s so there won’t be any speedo error to deal with. The other bonus: They are 2 lbs lighter per tire than the OEM rubber so the decrease in rotating mass may offset any increase in rolling resistance. Range effect will probably be minimal.

Okay thank you. That makes me feel better that I can get wider tires for it.
