Default CMP: Is everyone else as pissed as me about the 710's ??

I know we are all disappointed with the problems we all experienced with the 710's this weekend but I am even more steamed at the rumor that SCCA banned the tires.

The problems with the tires coming apart is a very serious concern, but as past history has shown (last years groove of doom on the Ecsta 700's) bringing a new tire to market sometimes requires changes to the tire composition early on, though this issue seems a bit extreme.

What pisses me off center's around the claim/rumor that SCCA banned the tire a few weeks ago and Tirerack still sold them to NASA racers. I am not sure how long ago most of you bought your tires, but Lionel and I both purchased ours a few days before the race.

At this stage we need to confirm if the SCCA rumor is founded and if Tirerack was aware of this. Right now it's all unsubstantiated rumor.

For those who were not at CMP and think this is an over-reaction look at the other CMP post on this board and look at Lionels front tire after only three sessions (two of which were on the rear of his car). 1/3 of the tire rubber is missing.

At this rate none of us will be alive to collect the contingency money !!!

DISCLAIMER: I have yet to substantiate the claim that the tire has been banned by SCCA so right now it's a rumor until someone confirms this !!!!

Regards,

Jon

Tirerack still sold them to NASA racers a few days before the race and Tirerack didn't say a word about the SCCA ban or potential problems.

I have bought tires (literally 50+ per season) from Tirerack over the past 7 years and am highly pissed they let me go out onn the track on a completely unsafe tire AND that they may have known about this when they sold me the tire.

</TD></TR></TABLE>

if the tire is unsafe I think they should have mentioned it or even pulled it themselves but I don't think it's there responsibility to tell you SCCA banned it. That's your own responsibility to figure it out. I'm not a big fan of tirerack these days either but IMO they shouldn't need to tell you that. There's plenty of products out there that aren't necessarily safe and plenty of people will sell them to you. It's your responsibility to have the info before you buy.

Steve,

With all due respect, it shouldn't be up to me to have to figure out if a tire is so dangerous it could kill me. They certanly don't need to say anything about SCCA's ban but they do have an obligation to their customers to make sure whatever they are selling is safe.

When a drug company finds out their drug is having unintended side effects that are potentially fatal or a car company finds out a few of it's delivered cars have fuel line leaks that could lead to engine fires (and hence be fatal to car's occupants) they don't just continue to sell the product without making changes.

We're not talking about the tire performing poorly, having no grip or getting bald prematurely. We are talking about a tire that is coming apart after only a few sessions.

I can guarantee you that had someone been killed at CMP (lord forbid) and their family went to court and proved that Tirerack knew the tire was defective they would lose the suit big time.

I also question why Kumho didn't tell Tirerack to pull the tire off the shelves.

Like is wrote in my disclaimer, the SCCA ban hasn't been substantiated, but even if it's not correct, given that 6 or 7 teams experienced the same sistuation (tires delaminating after one or two sessions) I think Tirerack and Kumho should re-evaluate selling more of the same batch of tires to race customers.

Just my opnion, but that is why I posted here to get other people's opinion, especially the other teams from CMP that ran the tires this weekend.

I really hope Kumho solves the issue because the tire, when it's not coming apart is very fast and grippy. Lionel set the "race" track record for H4 at 1:55.23 and I set the "qualifying" track record for H4 at 1:54.37 both records more than a second faster than the old record. I think the H1 record was also shattered.

And their cash contingency is the best I have seen in club level racing in years.

Cheers,

Jon

Calling Victor at Tire Rack, our wholesale guy, in a few minutes. VERY disappointed in the 710s. They worked great up until the treads started "firestoning" on us. $280 later for a used set of Hoosiers and Bob Woodmans mounting/dismounting services....ugh.
Will, did you get pics of ours?

I guess they weren't kidding when the early reports mentioned something about "great grip, but won't last as long as the old victoracer"

You guys are talking about a tire coming apart that quickly on a brand new, very smooth, patch free track with ambient temperatures around 80 degrees.

Had you run these tires at Summit in the summer they maybe would have made 5 laps.
Thats just *excellent* and a recipe to get someone killed. Drivers are responsible for keeping an eye on their own tires, but NOBODY expects this kind of stuff to happen. What if a left rear had popped right at the apex of the kink at about 115mph...

Scott, who's still spending the extra few bucks per set on Hoosiers and is happy to do so.

PS - You MIGHT get your money back for those if enough of you scream loud enough, but I doubt it.
And I doubt the SCCA rumours are true. If that really is the case, Tire Rack and Kumho are very liable for selling a tire thats already identified as dangerous. They'd be crazy to do that.

We had a total of 10 laps on them before I noticed the seperation(s). Left a message with TR. Will post results I get. Those that are doing so, too, please post results. We need to contact Kumho as well, probably as a group.

Jeff,

The question would be "Did Tire Rack KNOW there was an issue with the tire and keep selling it?" If so, yes, they are responsible.
This is how this scenario differs from your gun store question.

This is also why I seriously doubt the SCCA rumour is true. The Tire Rack would be STOOPID for continuing to sell this tire knowing that it is failing so bad that SCCA has already pulled the plug. And Tire Rack isn't stoopid.
My guess (and its just a guess) is that the rumour was Woodman trying to jump on an opportunity to sell a bunch of Hoosiers and Toyos.

Scott, who hasn't seen anything, anywhere about SCCA and the 710s.

I am going to call SCCA today and inquire if this is true if not I will post a message on this board with details. Quite busy at work so if anyone else has a moment call SCCA and find out the truth.

Just to stress at this point it's an unsubstantiated RUMOR until proven otherwise and we should give Tirerack and Kumho the benefit of the doubt until everything is clarified.

As for when all this happened! Well Harrison already stated 10 laps, and some teams had problems on only the second heat cycle on the first morning. I had six mounted tires so I was able to manage my tires better but after Saturday's race my tires were toast and had huge seperation marks on both fronts. Sunday's front's started to seperate as well.

I think my tires were the best of the bunch at CMP but I am less of a late braker coming from openhweel and Spec Racers where hard braking loses momentum. Lionel who brakes much later than I and would contiunally catch me under braking had the worst batch of tires.

When I race on Hoosiers, I know one set of four tires will be toast by the end of a two or three day race weekend, but it's usually a case of the tire having lost all grip, NOT a case of the tire coming apart or being run down to the cords.

Scott brings up an excellend issue, Summit is my home track and I can guarnatee you that those same tires would have met their fate much faster. While there are only two real hard braking zones at Summit (T1 and T5) the track surface is much more abrasive and during a hot July race would be a huge issue on these tires.

I hope this all get's resolved soon before the next race.

Regards,

Jon

No but if there is a know issue with the tire, and tire rack new ahead of time they should have let the people buying the tires know, that is Jon's Point.

If you blow a tire in the kink there's the risk of center punching a tree at 100+

Let's get this straight ! If a harness company makes a defective harness it's up to me to accept this because racing is dangerous????? I am supposed to accept that the maker of my fuel cell may have designed it wrong and it could blow up if I hit a wall???? Or that my Nomex suit has some deficiencies that don't enable it to withstand a fire in the cockpit????

Yeah racing is dangerous but I think most of us assume that certain items will work as designed. Yeah stuff breaks and their is no warranty on race items, but I expect my harness to pass all the required certification tests, as well as my nomex, as well as most other saftey items.

Yeah racing is dangerous but we do everything to minimize the risks otherwise we wouldn't wear harnesses and full nomex gear. We race like the folks in the 40s and 50's with no seat belts and a leather cap with scubba googles.

I have no problem accepting that some items may at times fail because of various factors but they should be isolated incidents not widespread across every product (in this case all the tire at CMP).

I can answer that- the pics above are from Lyonel's H4 Civic EX. We had that tire on the drivers side rear for practice (7 laps), qualifing (5 laps), & then moved them to the fronts for the race, that tire was drivers front & that happened on lap 5- although he did finish the race, so after it began to separate there were 9 more laps run on it (as if you knew Lyonel he won't stop racing unless he HAS to- we didn't know it was THAT BAD until after the race- yes he knew something was very "wrong" with the tire but didn't expect to see anything like that- I'm sure everyone 50 ft aroung heard my "HOLY SH*T!!" when I was scrubbing/inspecting the tires post-race) It wasn't particularly hot this weekend, & we didn't have any "odd" readings (tire pressure, nor pyrometer temps) on these during the practice & qualifying sessions prior to this happening. Although the new H4 CMP track record was made by him on lap 4 just before this happened, its a shame the tires aren't holding together, b/c they're really good until they fall apart!!

We have already contacted Kumho this morning- they are trying to make good- so if you were running these at CMP call Rudy (the contigency contact at Kumho) they are very aware of the problem now (obviously we weren't the first to talk to them this morning). The 710s are being pulled off shelf until they can get them sorted, so at least yes they are listening and won't be selling these until they get the issues sorted. We haven't called Tire Rack yet- so don't know what their reaction/response is.

I'm sure Lyonel will post more when he gets off work tonight, I just thought I'd give the "description of the picture" as requested as its from our car...... Danielle

The manufacturer, and seller, of any product that is known to be dangerous are absolutely 100% responsible for any damages that may be incurred by the consumer, if that consumer was not properly notified. The fact that Kumho or Tire Rack would sell the tire for competition use despite knowing of a potential safety issue is disgusting at best. As a consumer, we have the right to expect what we purchase to perform properly under the circumstances that it was designed for.

If when this is all sorted out, we discover that both of those companies knowingly put my friends at risk, I will not only boycott their products for life, I will go out of my way to encourage everybody I meet to do the same. Putting profits before people's lives is not acceptable under any circumstances.

Danielle,

Thank you for the update. I have contaced Tirerack and am awaiting the appropriate response from their higher ups! I am still amazed that Lionel finished the race and am glad he didn't get hurt. When I saw that front tire the first thig I though of was 110+ at the kink and what would have happened if it has suddenly gone down completely pressure loss.

You all weren't kidding about Lyonel (sorry about the previous mispelling) racing on the rotor if need be.

Matt, I agree with your post, but at this point lets wait till all the facts are in. I may have been a bit too hasty in my opening post.

Cheers,

Jon
