Reading through this forum it looks like 244/285 tires can fit on stock 20" rims without an issue . I have also read that the majority of members prefer the Michelin PS4s. I still have the original Pirellis (235/265) on my Cayman, and it's about time to replace them. As such, I'm strongly considering the 245/285 PS4s. The only issue that I'm running into is that I can't find them "N" (Porsche) rated. The local stores have the PS4s in 235/265 "N" rated, and standard rated 245/285 .Does it really make a difference to go with "N" rated tires, or will the standard Michelins suffice? Thoughts?
