Anyone running 285/35/19 on the back? When it comes time for new tires I want to go up 10mm to hopefully hook up better from a launch in the summer. Right now, first gear is pretty much useless if the temps are not in the 90s down here in Texas. I know pretty much nothing about tire and wheel fitment so if someone could enlighten me that would be greatly appreciated.

What tires are you running? How much tread is left on it? The issue seems to be your tires not hooking up because of compound/wear rather than the width.

275 is already pretty huge anyway, stock PSS sounds like it grips alright off the line but the PS4S is better. If you're running all-seasons or something a little more.. off-brand you'll have less traction, because just as rolla said, compound and wear make a difference.

OEM Pilot super sports they have about 8/32nds of tread on them still so fairly new. I always spin through first gear unless it is really hot outside.

Yeah, you need to get some temperature into them by design. You need to have them fairly warmed up to hook up properly. Reason is, the compound is meant for high temperatures on the track. The downside of it is, the low end of it (colder tire temps) are compromised because of how they need to stick at hot tire temperatures. If you still really want to go with a different tire, try getting PS4S XL. Even at same 275 mm, they were 1/2 inch wider than my OEM PSS SL due to wider inner/outer shoulder blocks. They hook up quite well off the line. However, they also need some temperature in them for best grip.

I used to hear that the PS4S was a little less resistant to high temperatures, and henceforth they would chunk a bit under high temperatures. I haven't heard of that happening with the PSS as of yet. If you want ANY sort of substantial performance, you need to have heat in them tires.

Yes I did +1 size 265 front 285 rear. No ride height mods. Stock. I think it nails it perfectly.
