Hoosier comments on new A40-S
HOOSIER Customers,
Everyone at Hoosier Racing Tire and our affiliated distributors and dealers are keeping a close eye on the performance of our new A40-S UMP Modified Tire.
It is my intent to attend UMP Mod events this coming weekend to see the results first-hand at Granite City, Pevely, and Quincy, IL.
We don’t want to rush to any judgment as early season track prep, weather conditions, and rule changes can often lead to unusual results.
One thing we know for sure from our tire testing is that everyone needs to reduce the amount and depth of their siping on the new A40-S. Let the tire do the work for you.
We single siped the test tires when we evaluated them and had no issues with chunking and the tires fired right away.
Also, the new A40-S will show a different wear characteristic than the old A40. Expect to see more grain and feathering. Buff the tire back to a smooth grain and race it again.
We found the new A40-S will repeat much better than the old A40 and the wear will prevent the tire from “sealing up” in marginal track conditions.
We had similar feedback initially on the LM30-S Late Model tire when customers oversiped and were too aggressive initially. Once they backed off their siping and got comfortable with the new wear pattern, they have been very happy ever since.
Yes, we need to monitor the situation directly over the next 2-3 weeks. However it is too early in the game to make any adjustments yet.
Thank you for your cooperation and understanding and please feel free to give us a call if you have any more specific questions.
Sincerely,
Shanon Rush
Product Manager

Hoosier released a statement saying all the wear was from improper siping... all the junked ones I saw at LaSalle had no sipes in them whatsoever....

round round we go...maybe hoosier can get American racer to give'em some tips...ump and hoosier want to make as marginal a tire as possible to get more of your $...imho.....funny thing is years ago all we ran was d's, everybody, with no issues then all of the sudden bout five years ago, they would wear out unloading the car off the trailer.

I hope the folks that cried about the D's end up with a trailer full of them junk things! Wait, who am I kidding, the ones bitch!ng about the D's don't buy new tires anyway.

Is anyone else having issues with these tires? Every one I've seen is feathered or shredded after just a few laps.
