I just finished the USCA event in Fontana CA and one of my Rival tires is coming apart on the shoulder. I have run pretty much all tires out there including R-compounds and never experienced this problem. The performance was on par with some of the better 200 tread wear tires out there, but I may be concerned about the construction and durability of the tires. Here is another thread I posted pics of the tire that is coming apart on the shoulder

Here's a good test result..... 2012 Stielow wins the OUSCI in Mayhem... in 2013 he runs the same track, same car, and I think he ran 2 seconds slower on the Rival tire...

Good point! I ran Nitto NT-05's, then went to Hankook RS-3's, OMG what a much better tire. I would run them now, but they don't make a 315/30/18. Looks like Falken may be getting a try.

There's a decent list of 'players' winning on Falken's. Sizes are somewhat limited though. They'd be my next tire if they made 18/245/40 - 18/275/40.

Out of curiosity, what areas made the Hankook's much better than the Nitto's?

The best tire is always the brand you don't have on your car. :lol: I'm a big fan of Michelin on my cars, BFG's on my 4x4's.

BOOM! There's the answer.

And he wasn't lookin' too happy with his tire choice that day.

The PCA AutoX'ers love them.

2.4 seconds.

Even Mark might say, comparing track results a year apart may not be a "good test". Wasn't it really cold last November?

Which spring was that again? :lostmarbles:

Ha. Don't you see the bright side here? By being tardy to the party I get to let others' tires literally fall apart first. :mock:
