Free Hoosiers for Stock 16/17

[Dinan M3]

Bought these from an NSXPrime member back in 2001. Since then my insurance company dropped coverage for track events. You'll need to pick up in San Jose near Santa Clara University. Cleaning out the garage before moving...

BTW, these are 205/45-16 and 245-40-17 which will fit perfectly on stock 97+ 16/17 NSX wheels.

Who is your insurance coverage through? What was the wording / circumstances (did you wreck on a track)?

Am insuring through USAA. They updated their policies a couple of years ago to exclude on-track events, timed or otherwise (gotta read that fine print, came in a letter updating policy T&Cs). Haven't wrecked, but certainly not willing to risk the car on-track without any insurance. I just rent formula cars for open lapping days over at Infineon and Laguna Seca. Full coverage, relatively low deductible, and 0-maintenance - just arrive and drive...

Vytas, you can have 'em if you want them. Email me, I'm not sure I have PM enabled here.

Hey, Ted. If Vytas doesn't want them, I'll take them off your hands. I will likely use them for SCCA autocrosses. Lemme know.

I want to make comments on old R compound tires. New tires when they are still covered with a release mold will last a few years. Usually slicks only kept for about 1 year. R compound slightly longer. Used R compound tires are purely junk after 1 year if it is not properly cared for. If it stored properly it will last up to 2 years. Anything over two years you are endangering yourself driving it on the track.

You don't want to find out the hard way. Take my word on this one. I almost totalled 2 cars because of this problem. Wished the guy told me it was old tires.

Per the Yoko rep at NSXPO, tire shelf life is on the order of about 5 years. If not properly stored all bets are off. These have been stored out of the sun wrapped in plastic under controlled climate and one set of rears has never been used, i.e., mold release agent is still on them. Definitely fine for autoX since there's not the same risk profile as at road course. Downside risk is simply that they may no longer be sticky, but only the installation costs are at risk if you test the limits with due caution.

Chris, you're second in queue, but given the remarks above, perhaps Vytas will let you go first...

Yeah, I figured older tires may not be as safe for the track, but for autocrossing, a little lost traction won't result in big damage.

[Andrie Hartanto]

the problem I experienced was not a little loss of traction.

The characteristics of old tires are very weird. They don't just lose traction, but they make the car undriveable. The car will feel understeer, and give sudden oversteer. Hard to explain, but it made me work my ass off. It was harder to drive on old tires than it was in the rain and muddy condition of 12 hrs enduro at Thunderhill.

This happens with tires stored at climate control environment too (ie. my living room)

Which Yoko rep said that? And does he mean street tires or R compound tires? I talked with Cheech from Yokohama USA on this issue during 25 hrs of Thunderhill. He confirmed that they don't like to stock a lot of race tires because of this exact issue.

That being said, auto-x is very low risk. In the end you may learn more driving this tire since it forces you to work extra hard

There's a hidden variable in your case. You bought old tires with unknown storage conditions and then stored them properly. If you assume relatively new or new tires stored continuously in a controlled environment, that's a totally different scenario. Seems worth experimenting to me - expected value in the upside case, ~$800; expected value in the downside case ~-$100. Assuming 50:50 odds in each case, the expected value is +$350. Seems like a reasonable bet...

The one stored in my living room was tires I bought from new. Used tires are bought to be used immediately. Storing used tires is asking for trouble.

Hmm, understeer to sudden oversteer, eh? I guess the rubber becomes hard over time, and therefore, doesn't stick as well, resulting in initial understeer, and then when they suddenly go beyond their stretched limits, they lose traction and are again slippery due to their hardness and oversteer badly.

LOL. Yeah, hopefully these unpredictable tires will help improve my driving skills!

I'll participate in the experiment and let you know how good or bad these tires are on the autocross.

another trick I used to learn car control is to run R compound tires in the front and street tires in the rear. Whooohoooo!

Keep in mind this is just to learn car control. Which enable me to push my car harder on circuit driving because I know I can catch it if I loose it.

 

[Vytas]

Andrie,

Thanks very much for your insight on older R compound tires. I won't risk running these on the track so I'll pass and let CiaoBoy try them for autocrossing.
