New Goodyears

[brian]

I've heard that GY has a new tire out there. Does anyone have a comments?

[Dave]

Mike Beaumia ran a set at the Sprints, Mike Knox said that they made 20 sets or so for testing and will have a new updated version or two before the Run-Off's.

Yes they have been avalable for maybe two months. At the new track in New Jersey was the first time I really got to use them (I didn't make it past turn one at Summit) I qualified 2nd and won after Roger broke. We did run together and I think they are as good as the Hoosier tire and I did get the new track record since it was the first national.

I also ran them at Watkins Glen two weeks ago and Roger and I again ran together for the last half of the race and I almost got Roger at the finish line. Dean Curtis also is using them and he did lead the race at one point but lost Roger and my draft late in the race but was able to run fast enough on his own to get third.

I feel that Goodyear has a tire that has us back in the game again. I do know they are not done with the developement and intend to do small incremental improvements until they have the best tire.

Thanks Ed. The last time I ran the GY they worked ok but had crowning issues and didn't last as long as the Hoosiers. Any thoughts on those issues?

[Ed Womer]

Brian,

I don't know what you mean by crowning and I have two races on the one set and they still seem to have some good life in them. Will they last as long as the Hoosier's, I don't know about that. The set of Hoosiers I had to buy in the begining of the season have two qualifying and two races and seem good but I am not planing on racing anymore until the runoffs assuming I have enough points to go to the runoffs. So I don't know how they will wear.

Is there a name or part number for the new tires?

[brian]

Crowning is an effect of air pressure increase that causes a rounded tire profile. Think bicycle tire. Depending on construction, all tires will grow with an increase in air pressure. Some will tend to stretch the tread area and cause a rounded contact area reducing the tire patch.

The last GY's I ran had this problem. If I ran enough pressure to go hard at the green, they would grow and get looose late in the race. If I ran them low, I had to go easy to avoid overheating them. Nitrogen fill would reduce this effect but is a pain in the ass to have to purge and refill the tires.

Ed, guestion is, which tire will you be on at the Ru noffs?

Is there a name or part number for the new tires?

There's only ONE "new" tire - any supplier will know which one you want.
For Brian ... the new tire has addressed the 'crown' issue. It is a MUCH flatter tread patch with a MUCH stiffer sidewall. I like it a LOT. Same compound as the old 'crown' tire - 430 - tried and true .

Brian, I will be on the Goodyears at the runoffs. Like Steven said the tire stays pretty flat and for me with start pressures of 16 & 18 and they end up at 20 & 21. They are consistent for the whole run and do seem to wear better than the old tires. The new tire is much narrower than the Hoosier tire but works as good. Again like Steven I like the new tire a lot.

I can personally say I have 2 cars on the New Goodyears and have NOT had any crowning problems! We start out at 17/19 ish depending on the day and throughout the race they stay very constant, the wear is very good as well

thansk guys for the input. Sounds like GY may have gotten it right, I'll have to try some.
