265/35-19 and 295/30-20 pilot sport 4S mounted!
Couldn’t be happier with the results. The 4S is SO much quieter, smoother and the traction is ridiculous! I went up a size all the way around and cannot see much of a difference in the speedometer. I used a GPS to check it against the car and it’s about .7 miles per hour off. So doing 54 actually doing 53.3
Have you noticed anything different with the larger front tires?
Also, maybe meriting its own thread and a lot of us pressuring the car manufactures, why can't there be a software adjustment for the speedometer error? It would seemingly be easily do'able, and here it is really needed because Michelin is not making the 4S in the original sizes.
