DaddyBuiltRacing Posted July 19, 2012 Report Share Posted July 19, 2012 Today I get a callfrom my buddy who's tuning my car. He says that they had to stop tuning due to something being wrong with the tires. He then explains to me that the rubber was seperating and that chunks of tire was going every where. This was on the dyno and on wastegate pressure (6psi). Tires are 195/50/15 Kumho AST's (yes I know they are cheap) http://i126.photobucket.com/albums/p81/alittlelessordinary/Car%20Pics/4dr%20GSR/tire.jpg http://i126.photobucket.com/albums/p81/alittlelessordinary/Car%20Pics/4dr%20GSR/tire2.jpg These tires have maybe 1000 miles of use on them and its most likely more realistically 700ish. They have never been launched on, no burnouts done on them ect...I use my slicks for that shit lol. Idk if I should try seeing if Jegs will warranty them out or if I should contact Kumho directly to see if anything can be done. Quote Link to comment Share on other sites More sharing options...
Farkas Posted July 19, 2012 Report Share Posted July 19, 2012 That's what happens when you buy shitty tires. Quote Link to comment Share on other sites More sharing options...
M0nk3y Posted July 19, 2012 Report Share Posted July 19, 2012 (edited) Usually tires have warranty periods to where you can get another tire within a certain timeframe if a defect occurs. That's with tirerack, I have no clue what Jegs will do. I wouldn't be telling anyone that it was on the dyno if I was you. Edit, it's a 130 mph tire...how fast were you dynoing it at?

DaddyBuiltRacing Posted July 19, 2012 Author Report Share Posted July 19, 2012 I have ran Kumho's for the last 6-7 years with no problems up until today. I have ran BFG and Falken in that same time frame and came away less then impressed. Quote Link to comment Share on other sites More sharing options...
Farkas Posted July 19, 2012 Report Share Posted July 19, 2012 Have they always been Kuhmo ASTs though? Like Kyle said, those are only rated for 130mph, which is why you'd normally see that type of 'chunking.' Quote Link to comment Share on other sites More sharing options...
neonkiller Posted July 19, 2012 Report Share Posted July 19, 2012 take em back to discount they will give you new ones Quote Link to comment Share on other sites More sharing options...
DaddyBuiltRacing Posted July 20, 2012 Author Report Share Posted July 20, 2012 Yeah I always run he AST's as they are $50 a piece and I don't typically do 130mph on the streets. I use my slicks for when I wanna race, and even then I haven't hit 130mph at the track (close but no cigar). Just strange that that this happes on a controlled enviroment setting such as the dyno. Thankfully it wasn't on the highway. What tires are a better option to a baller on a budget lol. I run $50 tires because I am poor point blank. I now however feel that these aren't very safe and would rather skip out on going out to eat and put money towards better tires. Quote Link to comment Share on other sites More sharing options...
DaddyBuiltRacing Posted July 20, 2012 Author Report Share Posted July 20, 2012 take em back to discount they will give you new ones Bought em at Jegs, gonna call them tomorrow to see what they will do for me.

DaddyBuiltRacing Posted July 20, 2012 Author Report Share Posted July 20, 2012 The more I think about it the more I think this isn't anyones fauilt but my own. I should've gotten a higher speed rated tire from the onset instead of being a cheap ass, lesson learned! Quote Link to comment Share on other sites More sharing options...

I now however feel that these aren't very safe and would rather skip out on going out to eat and put money towards better tires. How fast was the dyno running at though? The rubber (if there was any) from the roller could easily have an effect on the tire. It's hard to find a tire in a 15" size these days. I was going to suggest Hankook, as I've had good success with their Venus V4s, V12s, and currently have their R-S3s for autocross. If you're not doing any digs or anything, just find a decent tire with some speed rating, and when you're going to dyno throw the slicks on.

Jeff88coupe Posted July 23, 2012 Report Share Posted July 23, 2012 Dyno's are hard on tires. Don't dyno your car on tires that you plan on running at the track...it's kills them. I have a old set of worn dr's that I use just for when I put my car on the dyno. Quote Link to comment Share on other sites More sharing options...
twistedfocus1647545489 Posted July 23, 2012 Report Share Posted July 23, 2012 I applaud you for taking responsibility and not trying to lay the blame on anyone else.

DaddyBuiltRacing Posted July 23, 2012 Author Report Share Posted July 23, 2012 Hey I am going to call soon as I get home about the tires. I really appriciate any/all help. I call this a lesson learned. Fwiw I dynod on same brand of tires last time and didn't have this issue but then again it was a different type of dyno Quote Link to comment Share on other sites More sharing options...
Forrest Gump 9 Posted July 24, 2012 Report Share Posted July 24, 2012 That's what happens when you buy shitty tires. +1 You're making too much power for those cheap tires. The vtec is ripping those tires apart. Quote Link to comment Share on other sites More sharing options...
Got-Boost? Posted July 24, 2012 Report Share Posted July 24, 2012 I can't believe how clueless people are about tires sometimes... Never dyno on slicks. +1 NEVER....NEVER....dyno with slicks on! Don't believe me, do a quick youtube search and you'll change your mind... Quote Link to comment Share on other sites More sharing options...
