My current summer performance tires (Nitto Invos) are getting real close to showing cord, so I did a bunch of research the last couple days to find replacements. These tires will be my summer daily drivers as well as autocross and track tires (I also have a set of all-season wheels for winter, and a set of drag wheels). I checked out every ultra-performance tire I could find (I'm using 315/35R20 on the back). The recommendations always seem to go back to the Michelin Pilot Sport 4s. Most sizes are available now, but my size won't be out until June. The next-best tire is the straight Michelin Pilot Sport (which I used on the front for a few seasons until I wore them out last year). Hopefully, I can get an autocross or two in on my present set until the new ones show up in June.

Interestingly, there are a few other variations on the Pilot Sport made specifically for certain exotics like Ferrari and Porche. The stats are the same as the other Pilot Sports, so I asked a rep and he said that they are basically the same tire, but they just cost more.

I recall checking on this size earlier and the price was around $800 EACH because they were used of Ferraris. The price is much better now.

We’ve had several discussions recently... I’m a Michelin fan, much to the angst of the RSA fans.

I run a slightly taller front, but much wider, as my R isn’t lowered (yet).
Michelin Pilot Super Sport 275/40ZR19 (105Y) XL
Michelin Pilot Super Sport 315/35ZR20 (110Y) XL K1 Ferrari
I’ve got the K1’s in the rear, but as @dave rasmussen points, out the K2’s would likely be better.

In case you missed them, the relevant threads are here:

I''m getting nowhere quick in finding autocross/street tires, and I don't think my present INVOs will last past the next autocross.

So give it to me straight: Do you think 275/40/19's will work on the front of my lowered R?

What do you thing about going to 255/35/19 on front?

I'm looking at Michelin Pilot Sport 4s, but all they can tell me about the 315's is that they will be out "sometime this summer," which doesn't help me a lot.

I run the 275/40ZR 19s. My R is stock height. When I get around to lowering mine an inch in front, I don’t plan on changing tires. Here is a link to the thread where I posted pics of my tires and wheels. The tightest point of contact is at full lock, where the front outside sidewall comes closest to the front of the inner fender liner, see the third pic. IMO the gap would be the same if the truck was lowered an inch.

Here is the link I use to compare sizes:
https://www.tirerack.com/tires/tires.jsp?tireMake=Michelin&tireModel=Pilot+Super+Sport&sidewall=Blackwall&partnum=74YR9PSSXL&tab=Specs

The 255/35ZR19 would easily fit as it is about 1.7” shorter than mine. I’d have to do some ‘cipherin to stock aspect ratio and sidewall heights to see if I think I’d like it. From the pics above, you can tell I’m a wider tire is better kinda guy.
