I run asphalt take-offs on my car and was just wondering if anyone has ever heard of grinding the sidewall on these tires so it acts more like a dirt tire? Just want to know if anyone's tried this or what your thoughts on it are. Thanks.

I WOULDN'T SOME TIRES LIKE THAT ARE VERY SPONGE-LIKE AND REALLY DON'T HOLD AIR VERY GOOD,EVER TRY TO KEEP AIR IN THEM FOR A WHILE? AND GRINDING ON THEM WILL DEFINITELY MAKE THEM WORSE,BY THE WAY THERE ARE SEVERAL DIFFERENT TYPES OF THESE IF THEY ARE THE ONE'S I'M THINKING OF AND SOME HAVE A SIDEWALL THAT'S ALMOST TOO THIN,IN MY OPINION.

justin, you can grind the sidewall of an asphalt takeoff and the tire will work better. i've never done it but when i first started dirt tracking there was a guy that used a bondo buster with a 40 grit pad on it. he would grind off 1 layer on the sidewall. he used that green slime in the tires and ran them tubeless. it worked for him as he was factory stock champ that year and nobody could touch him.

it wasn't just the tires though. he did a lot of little things that when combined added up to a big advantage.

I'm sorry but I think you are nuts to try and alter the sidewalls. You couldn't even begin to be consistent all the way around. Even if you dont care about your own safety, think about the other racers who may have to eat or wear your crap tire as a necklace. If you cant afford tires, you probably wont pay for safety either. Sorry to come down so hard but this is dangerous. IMHO

yeah, i thought the guy was nuts too.....and he drove those nuts right around me every week to the championship.....the same "nut" also ran what a lot of you guys call a "quadra-junk" when everyone else ran a holley. my point is this....no "one thing" will give you a huge advantage, at least not legally. the advantage will be the cumulative effect of lots of "little things".

range, i wouldn't grind the sidewalls of a street tire. asphalt takeoffs have stiffer sidewalls and there is some advantage to be gained. street radials already have a flexible sidewall and there's nothing to be gained from grinding on them. of course this is just my opinion.

bobaluuu, you can take a consistant amount of rubber from the sidewall by using a bondo buster with a 40 grit pad and sanding the sidewall with the tire/wheel assembly on the front spindle and the car jacked up off the ground. the swirling action of the sander will rotate the tire as you're removing rubber.

i don't like the idea of jeapordizing the safety of myself or my other fellow drivers anymore than you do bobaluuu. That's why I haven't tried this yet, and decided to seek input from others, to see if they have done this safely and successfully.

I totally agree with outlawstock17 that it's all the little things added together that will make you a successful driver, and that's what I'm trying to find, the little things that help. The asphalt take-offs I use are not that thin in the sidewall and are pretty stiff. Outlawstock17 was also correct, IMO, in that you CAN be consistent with the amount of rubber you take off of the tire. I use a belt sander to get the glaze off my tires and if you run it at a certain angle to the tire, the tire will spin while it gets sanded. The speed that the tire will spin will vary with the angle the sander is held to the tire.

I apologize if I stepped on any toes with this topic. Thanks.

like i said if these are the same hoosier brand asphalt takeoffs,i'd look for more options i'm probably giving out too much info even for the forum, we buy them only after we explore every tire the supplier can get,they make 10+ diferent types of these tires some with a sidewall so thin you can turn it inside out like a bicycle tire,tires are extremely important if u can't find them like i'm talking about then break out the grinder.

[In retrospect my words may have been a little too harsh, especially my personal judgements of others. For that I apologize sincerely. But I do believe there are ways to save $ without jeopardizing personal or others safety. Thanks for allowing me my views on this great forum.

no offense taken bobaluuu, everyone has different opinions and hearing them all makes us all better racers.

bobaluu, you can't protect all the world's idiots, but you can try to protect the rest from those idots.

You weren't to harsh.
