Does anyone make a extreme performance non run flat c7 z51 tire? Can't seem to find one.
Thanks

Sir Nuke

Using Tire Racks search....these are all of the "sets" available for a Z51. 7 different Mfg's, 12 different tires.

It's somewhat odd that they don't rate the PSS as an extreme performance tire but then again, the whole Max, Extreme, etc. ranking is something TireRack made up anyway.

Technically there aren't any "extreme" performance tires in our sizes but I would argue there aren't any tires more "extreme" than the Pilot Super Sports out there so it's a meaningless classification. The tires they rank as extreme, like the Bridgestone RE-11 are great tires, I owned a set, but don't provide better performance than the PSS tires.

Everything else on the list of tires that fit the Z51 are a step down from the PSS but they are all non-runflats and cost significantly less so if maximum adhesion isn't a requirement there are some good options. Tirerack also doesn't carry Nitto or Toyo, both have good tires in the Z51 sizes.

For what it is worth, I have two sets of wheels for my 2014 Z51 Auto with 668 rwhp. The stock 19/20" Michelins and a set of 18/19" TSW with Bridgestone Potenza RE970AS on them, 295 wide in the rear.

I am able to get 3.6 seconds 0-60 on the Bridgetsones but only 4.2 seconds 0-60 on the stock tires due to more wheel spin. This is with 30 psi and 60-70 degrees weather on both sets. Also the smaller wheels don't scrub when turning at low speeds, have better ride quality, are lighter, and the tires are cheaper.

I think the larger wheels look better and are better for cornering.

Thanks for helpful responses. I'm used to the RE11s from my C6. I think they did everything better than the PSS run flats. Perhaps I'm just not in love with the ride and handling of a run flat. You'd think there would be a dedicated extreme non run flat out there. Some of my friends went to the Michelin AS 3 tire and are real happy with everything about their choice. I'm just not into an all season vette tire.

Pilot Super Sports in non-runflat guise are simply awesome tires. I cannot imagine not being happy with them for most applications.

PSS non run flats. Wonder if they handle any better than run flats

That's what I bought for my Z51 and my GT-R. Excellent tires. As for extreme and other Tirerack ratings, that is really made up by them and kind of irrelevant as others have said. Hard to find a street tire that is much better than MPSS's overall.

Great advice! So what do
You think the non run flats will feel like in the run flats in the PSS tire

ect

i was told by michlen that they no longer make the same size pilot ss for z51 in none run flat . you have to get the next size up 255/295

I sure would like to have more people confirming that the 18/19 TSW wheels do not rub the rear fenders. I have read a number of posters on these forums complaining about the rear tires touching the fenders under various circumstances. Seems quite reasonable considering that the stock rear offset is 79 mm. The Nurburgring is 65 mm and is also 0.5" (12mm) wider. That makes the TSWs stick out close to 20mm (14+6) more than the stock wheels.

Yesterday my stock wheels/tires rubbed twice when hitting some shallow dips at 70MPH on a country road. Stock wheels usually sit too far-in but, in this case they are actually too far-out, as I found out. I can not imagine them not rubbing if they were sticking 20mm further out.

My car is lowered on stock bolts but, only 0.5" so, that really should not be much of a factor.

Wonder what this set up would do to the speedometer accuracy (+/- ???)

Mine have never rubbed, stock Z51 or the TSW Panoramas. It is at stock ride height. The Bridgestone RE970AS tire diameter is 26" versus the 26.7" stock Z51.

Yep - bought a set for the wife's Stingray, and while they look great they definitely do rub. I had to raise it some, and still have to raise it more as we rubbed on freeway dips on our trip down South this past weekend.

Sorry to say this, as the wheels look great.
