So when I did my widebody fenders, I decided to buy 345/30/19’s cup2 rear tires.. but now i went and added a supercharger looking for 600-650 rwhp. My question is will these tires hold up? I would hate to buy new tires after spending $1,100 on these! Thanks
Yes they will hold up for about 6,000 miles. Everything is a trade off, you want a tire that is sticky enough to get the power to the ground, ? you are going to sacrifice longevity.!
You want a SC corvette to act like a SC Corvette, these tire will do that. This tire was designed for one purpose. and its good at that purpose..
Like Bill said, they are an extremely good tire for traction but a soft sticky tire has it's disadvantage too, and that disadvantage is mileage. I would give them no more than 12K miles before they will need replacing. I bet they were not cheap $ either
They'll do perfectly fine for street driving with the centri blower as long as you don't expect them to dead hook a 1st gear launch. No need to rush out to buy stickier tires, they should last you a few years or more with it being a weekend car. If they're still around by then, I plan on checking out the Kumho V720 ACR 355/30/19s for a fraction of the price of the Michelins or even R888Rs.

I agree. Having experience with Kumhos, I'm sure the grip will be there but they don't last long. My only concern about a 355/30/19 is the diameter @ 27.5" tall. That might be an issue.

On paper it should be, but after doing a bit of research on the tires, I vaguely recall people reporting that they run small (closer to a 345). I'd double check again before I actually bought them (and look for more feedback), but if I get the 305/45/17s to fit, they'll fit haha

Running small usually refers to tread width. There shouldn't be much deviation in section width and overall diameter, though.
Yeah, if you have no problem fitting those big 17's, those Kumhos will probably fit. lol

Interesting, I'll have to do some additional research for sure before pulling the trigger then. I can't believe how much cheaper they are than the few sticky 345/30/19 choices out there, so they're definitely my top choice to try once these R888s age out.

$1,100 for the rears. I’m just happy I could use them!

I have never used those personally but by looking at them I think they would do better than most if not all regular street tires but fall short of drag radials when it comes to straight line traction... it depends how you drive too, you could also have the tuner keep it soft around peak torque to make it a little more manageable but where's the fun in that

well to be honest, before the supercharger my car had just a tune, headers, cai and on a 45-50 degree day I could spin 2nd gear.. I guess time will tell.
