    Is this a done deal for next season? The reason I ask is I am begining to hear a lot of chatter about Hoosiers having significant wear issues and cording after just a few cycles. I am referring to the R80 and R100 compounds specifically, not the truck tires they call Ovals.

    I've been loyal to Hoosier for many years myself, love how they feel and availability of sizes, but I've been experiencing my own problems since March of 2011. I thought it was just set-up issues with my Porsche but I was never able to find a problem with the car and then I corded the first set on the 355 CH in 4-5 cycles. And now hearing lots of other complaints from drivers and driving coaches who experienced it with customer cars.

    If I were not driving a spec tire, I would be looking at other brands right now as Hoosiers have become too expensive to run due to these issues. Just wondering what 2012 holds for us with FCRA?

    Ah yes, the RennList scare...

    Have not seen any issues here, but I know these tires are very sensitive to camber. Many of the reports are from folks driving on "rovals and burning up the inside because of too much negative on the inside tire...

    What we have seen is major wear on the outside of both the front and rear passenger side tires. However on "Oval" Hoosiers I have run 8 cycles with even wear. I suspected camber problems on Rob's car but the settings are at spec negative or more. So the cording should be like you say on the inside but it's opposite!

    Interestingly, the Rennlist thread popped up after someone else brought it up at the track this weekend thinking they had a unique problem. Then I recounted my experiences, Dave Scott added his observations, and now that Rennlist thread from a completely different part of the country.

    My problems started in March of 2011 and after confirming my suspensions settings on the rack, Hoosier replaced the 3 tires I destroyed that weekend under warranty. I've been chasing early wear problems ever since. As Colin said, this is R80 and R100, no issues on the Oval tires but I really don't like that tire. They seem 'numb' relative to the regular slick.

    I really do love Hoosiers. They come up to temp quickly, give great feedback, handle higher slip angles nicely, and they have supported NASA with a contingency program. It's the only tire I've run for the last 5 years or so. But I've gone from getting 10-12 heat cycles to now 4-5.

    Im not lobbying for a change here, but if Hoosier is no longer a sponsor then I would love to try a new tire. Maybe Pirelli or Yoko would like to sponsor?

    We have a brand new, state of the art, computerized wheel balancer by Hunter. We have only mounted two sets of Hoosier's but have found that on both sets the road force numbers were unacceptable.
    The machine loads the tires in both CW and CCW direction to determine "pull" caused by tire construction. A good number is 9, the limit we use is 24, the Hoosiers measure 38. The machine even measures wheel run out and all rims had less than .008". Even recalibrated the machine and called Hunter. Tires were at fault. Oddly the driver felt nothing unusual but did not put many heat cycles on them. we will see?

    And that seems to be the issue - was as drivers are not experiencing problems seemingly over driving the tires. We are blaming our set up, the track, or our fast laps. Your insight seems to eliminate all those items from the analysis. Time to talk to Hoosier.

    have they changed construction or formula starting in 2011? I have run the R80/100's for 5 years. even this past year with FCRA I didn't have any issues with Hoosier except a sidewall split at Sebring noticed after last race (no blowout). tire had 5 cycles at that point and I was taking the Jason Hart turn 7 inside the curbing line. :D the split very well may have been my inside wall hitting backside knife of the curbing.

    I got 8-10 cycles out of my Hoosiers in FCRA this last year. I used my VIR race tires at New Jersey and won both races cycles 5-8.

    I know some of the 430 guys were using 4-6 sets a weekend! :eek: I used 3 sets for 4 FCRA weekends.

    I had heard one hypothesis that something happened to the compound and/or construction after the deal with Continental Tire went down. No way to know for sure, Hooiser has never said anything about it. Plus we don't know if we are seeing a specification change or if these are manufacturing defects. But after blaiming myself for a long time, I'm now pretty convinced its the tires and not me.

    9-10 cycles would allow me to get 1 race weekend plus a day of practice at the following event, which is what needs to happen. I've budgeted 1 new set per weekend, just like I always did with NASA (until 2011). If that increases to 2 sets I will have to adjust my budget somehow and possibly give up a weekend somewhere.

    2011 was a tire disaster. After running out of tires at TWS, at the events that followed I had to ration my laps and skip sessions to ensure I had rubber to race on. One benefit though, I got pretty good at qualifying. When you tell yourself you only have 2 laps to get the job done (in order to save the tires) it creates a sense of urgency that makes you go faster. I out-quali'ed Matus twice this year (he finished 2nd at Nationals) and Klenin on his home track (he took 3rd at Nationals). :)

    With regards to winning races on cycles 5-8, as I've said before, you get more out of a sub-optimal car than anyone I've ever raced with. If you ever spent the time to set-up your car or spent money on tires I'm not sure I'd be able to keep your tail lights in view.

    I think its my driving style the lends to the life I get out of tires. Without ABS in the Spec. RX7 or ability to trail-brake without flatspotting you have to drive smooth. I'm happy with my lap when under braking I feel like it is blown only to have it gather up for turn-in, able to come all the way down to my apex, and then on track out thinking it is going to be 2 off only to have it stay on (90% of the time :)). All of this feeling like just a few light fingers on the steering wheel not fighting anything. That is the top of the mountain for me and I have never made it, but I try each lap! I think the key is my light hands and smooth, I'm willing to saw in the heat of race battle to test the friction circle, but to me a beautiful lap has minimal input and smooth.

    Smooth hands and smooth feet have actually always been a strength of mine as well, every coach I have had has commented on that. My driving style is not causing the problem. (BTW, I also got my racing start in a car without ABS)

    The video here is a little long, but it was a very exciting race if you choose to watch it. :)

    With two race, three day weekends, I can't imagine using less than two sets

    5 cycles for the 2 race days - 1 practice, 2 quali, 2 race

    Then take the set to the next race for 4-5 cycles on the test and tune day. Start next 2 day race cycle on stickers. Lather, Rinse, Repeat.

    Typically I suspect we'll have the opportunity to do more than one practice. I certainly understand you may sit out sessions to save tires and other wear and tear. I'm thinking ahead to any tire use limits that may be established. Two sets should be the minimum IMO. My experience with the 430 in a few races last year was that we couldn't make the weekend on one new set.

    the 430 certainly burns much more tire than the 355. I can easily survive on 1 set a weekend even with 3-4 practice sessions. My practice set is the previous weekends race set and then fresh slicks for qualifying. I also don't believe in more than 2-3 good practice sessions especially when hot, from that point it is diminishing returns for my car and personal sharpness.

    rumor is you Will and Jerome had several 1 cycle tires. :D

    Just got a report from Sebring - a friend was coaching a client out there and had a Hoosier R100 delaminate on the front right while on the back straight. Tore up the car pretty bad.

    I put some used Ebay Michelin slicks on my 996 this weekend, the same car that had been eating Hoosiers up. Ran 3 cycles, tires looked great despite already having been used. Hoosiers would have already exhibited wear on the shoulders.

    Can anyone answer my original question, is Hoosier still our sponsor in 2012? If not, I am getting off the HoHos and moving to Michelin or Yokohama ASAP.

    Need more info. Kind of car? Camber and suspension settings? Pressures? Driver/team experience? Etc. I have seen one failure and read about others, but it's impossible to know what they mean without more.

    To my knowledge, Hoosier is very enthusiastic about the series and wants to work with us. John H can speak to that.

    Just curious how many race miles do you get on a set before they start to go?

    We get about 128 race miles at the Ring but could probably do about 150 without issues.

    Jim, I suspect it varies from team to team, but if we got half your number we'd be thrilled. Last year's compound was pretty soft. Regards, Will

    Jim, doesn't P4/5C have wider wheels and tires than an F430C? Not much, but a little? Do you use Pirellis, Michelin or Dunlops? Sounds like your wear is right in line with what I see on GT cars with those makes.

    At competitive lap times, close to record pace, I see in the data, a decline in the performance level of Hoosiers in about 45-60 miles to a second tier of performance, a stable, less quick level that lasts around 45-60 miles, depending on the abuse they receive.

    YMMV

    Interesting. We could only run our super soft's at night when it got cold.

    Best

    Huh? I'm not asking for the series to change anything, just asking what my options are. If they are a sponsor, I will run them. If they are not, I will pick something else as I think the cost/benefit ratio is better with other brands.

    Try not to over complicate things Peter, it was not a difficult qestion that I asked.
