If I had not done stripper therapy on my car I be driving to/fro track on kuhmos/Hoosiers. I miss the easy nature of going to track and coming home wo the drama of loading/unloading/hooking and unhooking etc- literally spend 2 hours to get prepped to load car to head to track and another 2 hours when i get back to unload and unhook this and that. But forget driving in the rain- it is scary!!! Always better not to drive to/fro- u get more hc's- how many more don't know. Mike

My car is gutted full cage single halo seat- no dice for me. If I hadn't done the stripper I be doing the same as u. Wouldn't work for me even I wanted to drive it- got no crash bumpers to support a hitch. Mike

nice mike what does your car weigh
i'm still stock and drive to and from or leave my car ..nothing like having your coach run a race shop near the track and can do track support, car storage, store extra wheels..just show up and drive....almost died once in a rain storm with nittos a couple of yrs ago...

FWIW I decided to just go wth the Nitto's. I needed a tire I knew was going to last even if it meant going slower. The Kuhmo's were tempting but there were too many questions in my mind on exactly how long they would last so I went with the safe bet.
I honestly didn't have an issue with Sport Cup's I ran last year but they did suck the last few heat cycles of their life (think they had 32 heat cycles in the end). If they weren't the most expnesive of the bunch I would have run them again.

forgot to mention that my first set of nittos were defective with inside of tire bubbles in 2 tires (first track day on them) ...luckily ccw was great and as i bought the tires with the wheels they took the tires back under warranty and i got a refund..great service there...so kuhmos arent the only ones......

Very bad news on the Khumo trial - slicks, 280/18s - 6 tires on 4 cars on heat cycle 5-6 all went ginormous sidewall hernia within one race meeting (2 heats) today. One car off, others just had to tap off half way thru after picking up vibrations - which was smart. Will post pics tomorrow but hernia bigger than a baseball on all the tires. Seems u get what you pay for. Dealer refunding/crediting but taking a big knock after importing 30 sets of these.
Could be a bad batch but tires off cup and rs and plan-jane3s from fast to slow drivers means its quite a solid sample. Surely they'd know this was the reality - do they expect people just to ignore this? Do they care? Track was 15degrees and moist. Might be the tire can't handle 911 rear weight and power at same time - all bubbles on rears.
Audi's safe bet is my choice - Dunlops arrive Wednesday, and they're 300mm wide but costs about 40% more

Resurrecting this thread,
Been researching tire options for this coming season. I'd had mixed experience with the kuhmo's, wear was good, grip was okay but the backs didn't like the 12" rims that i run. I think some of the reported failures could have been from stretching the rears on 12' rims. On a few occasions I had the sidewalls roll over on me, maybe I wasn't up to full temp, but disconcerting, and probably putting more stress on the tire, than designed for. Last year the only rear option was the 305.
Don't know when they came out, but on Tire Rack kuhmo is now listing a 315-35-18. I'm going to try these, of the four or five sets of hoosiers that I ran last year no matter what i've tried I can't prevent the fronts from rotating under braking or the rears from rotating under torque.

Funny. Ran 5 sets kuhmos and 3 sets Hoosiers. Maybe just bad luck and hotter days with the Hoosiers but my best times are always so far with kuhmos. Until just tried pirelli slicks. A couple secs faster

^so far same sentiment. Still working on hot pressures though. I mite go up to 36 hot as some had suggested. Started at 28 hot it was sloppy and gone to 34 feels better. Mike
