I wanted to bring this up because I was surprised that using such a marginally narrower tire would cause such significant pull. Maybe worth a sticky if other people pipe up with the same issue.
I bought my 2020 GT350 last fall in Kansas City, where it gets very cold. The car is my daily driver, so I put all-seasons on my cars in the winter so I don't loose grip. I've felt what that's like and it's not fun. I was running Michelin Pilot Sport All Season 4 tires in 285 section width - common size alternative that I've seen people using for an all-season in this model for winter driving. I read no other reports about the tires causing a radial pull. I discussed it with the folks at Discount Tire and they thought it was not enough of a size difference from stock to cause an issue.
I even had Discount Tire try an entirely different set of these tires, and we swapped side to side to rule out radial pull from a bad tire mold, and it still pulled left. After over a month at a very fine Ford dealership service center, and their trying everything all the way down to tweaking the subframe, they finally got ahold of a set of wheels and tires that matched the factory width, and low and behold the 285 tires were what was causing the car to walk across lanes. I'm going to chalk it up to the steering/handling/suspension on the car being engineered so precisely that the tires just didn't have enough grip to make the car happy.
Has anyone else experienced this? Not that I'm anyone of any kind of sway, but I'm going to call Michelin and put in a request to their feedback team to make the PS AS 4 in at least 295, because I do want to continue to drive the car when it's cold. I live in Asheville in the mountains now and snow is only very occasionally an issue, just colder weather during winter. When I bought the car it was on a square 295 snow tire setup, I think they were Blizzaks but I could be wrong about that. But they lost all of their grip as soon as it started raining. I'm talking they made the Sport Cup 2s look like wet grip champions, and they still had significant tread on them.
