I don't have great photos handy, but hopefully these get the idea across. First is with 325s and you can see they angle back well under the fender. Second is with 355s.

355s look great, much better fit. Any TC issues with the diameter?
Im about to do 345/30/20 PS4S on a 20x13 HRE wheel which has about the same diameter as your 355/25. Just curious what I should expect...

The 355-21 or 345-20 rear tires yield similar F/R difference as people run R7 in 295/345 combo on the 19". So TC or ABS should be ok if those who track the R7 haven't report any issue.

I've complied a list for reference:

I ended up getting a set of Michelin 4S 355/25/21 for the street and mounted them on OEM spec 12.5” wide wheels. When I compared them side by side with 325 cups on the stock wheels, they were exactly the same width. Fitment seems spot on, so another confirmation for the sizing option for anyone going with a 4s.

Yes the 355 PS4S is exactly the same width as the stock 325 Cup 2 but with shorter side wall. I have had them on for a couple months and so far no issue with TC.

Considering to do this on my RS that is only road use + mountain carving.

Front 265/35/R20 N0
Rear 355/25/R21 Premium Touch?

Would love to hear ownership experiences after running them for a few months now, are you running OEM alignment or more camber/toe?

What updates are you hoping to see? 355s are the correct size for PS4S tires and they work great. I run stock-ish alignment.

Would like my questions clarified if possible?

Sorry to hijack an old thread but what do you prefer for the rear? 355/25 or 355/30?

There is only 355/25-21 available for PS4S and looks like they've raised the price on these. (was $900 last year)
