I've seen the occasional bit of dissatisfaction for Hoosier tyres and also saw a thread on Pelican where a guy showed some sidewall failure pics.

Has anyone else suffered similar or other failures of these tyres?

It seems to be happening a bunch with folks I know, Patrick. I have seen some of the failures, and they are not pretty. In addition, excessively rapid wear seems to be happening more and more with these.

I like the R100's, but IMHO Hoosier has a real problem...

Hmm, that's a bit of a concern Dave. Seems like Hoosier are staying pretty quiet about this too. Are there any common symptoms and preventative measures?

Veloce Raptor

The symptoms I have seen include aggressive tread delamination and weird sidewall chunking.

Interesting. Have experienced heavy wear with these slicks (2900 lb factory race car) compared to our primary alternative, Pirellis. Also, know of one failure, not on my car. They haven't helped my tire budget. Maybe a harder compound will help, but at what cost in performance? Have heard Hoosier's warning to reduce camber.

I corded a pair of NEW fronts in ONE DAY at VIR a few months ago. 997 GT2. Assumed it was an alignment issue but I put on a set of R6's and no problem.

I have run several sets with no trouble.

What corded, the inside edge or outside edge? How much front camber?

You may want to watch the R6s closely as well. I had one set ( 2 rears) separate inside at the core and create ballons on the surface that contacts the road. I saw another person with the same issue at Roebling in Dec.

Inside. Camber was everyone's guess but the rate at which they failed was surprising. Don't recall the exact number but it was mid/low -3 deg, wanna say 3.4. Acutally wear went through the cord and steel was shown and coming apart......in 60-70 minutes of DE driving.

I definetly watch the R6's too, thanks!

In theory, that could be a little high for Hoosiers, but it still should certainly not have caused that to happen. My problem has been excessive wear on the outside edges. I keep cranking up camber to try and control it but continue to have problems. And this is happening on two different cars - my 996 and 355 Challenge.

Problem only started around March of 2011. Ran all of 2010 with no issues and suddenly I am destroying tires at a rapid pace.

Having seen this on others' tires as well, I am convinced that Hoosier has a real problem with the compound of these tires, which seemed to change when Continental bought Hoosier a couple of years ago.

That's actually more than mid/low camber I would have thought. Not super excessive though. Also, what about toe out? You could have had more than you realised and that will definitely increase inside wear. Was that checked?

jakermc

Hoosier generally recommends much less camber than other brands of slicks and R-compound.

Bman

Yup! it was good and I continued to run the same alignment on the R6's with very even wear. Quick wear happened on both fronts, left front was more dramatic.
