Do you think this chunking off of the tire is acceptable?

These were driven on the track on 3 occasions:

 

wow, get rid of that tire! i know alot of people run on messed up tires like that but that **** is dangerous, and if your gonna do another track run with those thats even worse.

 

Agreed. I wouldnt risk it at all.

 

Just out of curiosity, what kind of tires are these?

 

is this a common thing for tires? should I try to warranty them?

They are federal 595...I know you guys will say these are cheap tires, not made for the track and I probably over drove these a little but Im wondering if a comparable kumho or michelin or something would the same thing happened?

 

if its for the track only then you should just buy some drag radials. A federal tire is a cheap tire hands down. kumho and michelin tire's are a better quality tire than a federal tire. But what you see can happen to any tire.

Not this bad, no. It's not uncommon for street tires, particularly those that are not particularly high performance or high quality, to have small chunks come out (maybe 5-10 mm in diameter), but I've never seen anything this bad.

No. They happened as a result of track use.

It depends on the kind of tire. Their top-of-the-line performance summer tires would not have the same thing happen. Their cheap all-season tires? I don't know.

I disagree. Drag radials are good for the dragstrip, not for the track. Drag radials are designed for acceleration, with sidewall reinforcement to allow them to be used at low pressures (for a larger contact patch).

If you plan to go to the track a lot, you could get some R compound track tires, if you have a lot of track experience; otherwise, a good dual-purpose tire (e.g. Falken Azenis RT-615) might be a good idea.

 

thanks extasy guy,

well these arent all seasons these are a dedicated summer tire, very good for the price! but just not trackable. A drag radial wouldnt help me cause im driving on a road course, and i need something to drive to and from the track on, so im thinking the proven 615. sux tho cause otherwise these tires still have life in them...thanks for the input

 

Falken Azenis are nice tires i put them through the tests a couple times and they worked real well.

 

oh how are the deygo's? i heard they were good

 

They are awesome. Deygo nicely

 

i meant to say buy some track tires like the kumho victoracer and such tires like that or the falken 615. thanks nsxtasy for catching my mistake

 

anyone have experience with kumho on the track? i had some that chunked really bad like these

 

damn wont be buying those then either. what model did you have?

I've used Kumho V700 Victoracer track tires, I've instructed folks running the Kumho SPT, and I've known folks who have run the Kumho MX, all without chunking. But Kumho also makes some all-season tires and some not so great tires and it's possible their other tires might chunk.

If you're going to be doing a lot of track driving, like vtecsi00 and I both said above, you ought to get yourself either some R compound track tires (the Toyo RA-1 and Nitto NT-01 are both popular choices) if you're not going to drive them on the street, or the Falken Azenis RT-615 (which you can get from Vulcan) if you need to also drive them on the street.

 

i dont want to step up to the R compound yet because the price and that I want them to be DD friendly

 

"Falken Azenis are nice tires i put them through the tests a couple times and they worked real well. "
x2

 

If I ran the Azeni, I would have to run a 215/45/16, which is 2.5% off. does anyone have experience ? would this make a huge difference in final drive,etc?

 

What kind of car is this for (year, model, version)?

 

sorry i should have specified.

its a 92 honda accord ex...I am running a 16 inch wheel in which the proper size would be a 205/50/16. but the closes azeni I could match was the 215/45/16 which I wouldnt running because it would give me a little more width and an smaller sidewall.

stock size for my car is a 195/60/15.

thanks for the help all

My suggestion would be to try the new Dunlop Direzza Sport Z1, which is available in 205/50-16. It appears to offer performance very similar to the Azenis (e.g. it beat the AD07 and KD in testing, but not the RE01R) and it's also priced similarly too. And the diameter is right for your car. Yeah, it's narrower, but 10 mm of treadwidth isn't going to make a huge difference.

 

yeah ive been running 205s the last time.

you reaffirmed my decion, going to try those I think if the price is right.

you may have read my other thread on the new dunlops
