I picked up a set of Hoosier RS03's dirt cheap in hopes of using them at Road Atlanta in Aug. I was told they only have 2-3 heat cycles on them. They show no signs of dry rotting or splits. Lots of rubber left on these. My only issue is the late 2002 code on them. Thats 6 year old rubber

My question is: Are they just going to be a little slick, or am I risking them coming apart on track with me? They have been stored mounted on wheels, but with the valve cores removed. They were not in bags, but have been in a garage.

What do you guys think?

I ran a set of R3S03's all last year, they had one heat cycle on them and were like 6 years old as well. I ran them at Road Atlanta 2 Times, Roebling and Talladega GP before they corded the last time at RA.

And my car was weighing in at 3650 lbs with me in it. And not DE pace either.

So I think you'll be ok as long as a close visual inspection is cool, no major sidewall, or any tread cracks. They are pretty good tires, very solid on the rear end, pretty flexible with temps as well. I really liked them.

The tires should be fine structurally --- the rubber on the other hand will be rock hard and the tires will be very greasy. No where near optimal traction compared to a new set. I would run them and take another set of wheels/tires - even your streets just in case.

I tend to use things up, so I would put them on and try them for a few laps. It would be helpful if you had an extra set of rims and rubber in case they have a problem. I don't think anybody can guess if there will be a problem. Be fair and don't psyche yourself out. I think the likelihood of catastrophic tire failure is low. The most likely sign of age would be sliding/loss of traction due to hardening. If you aren't racing or in a time trial, it is just another learning experience.

scrub them back and forth a few times like the nascar guys do, they'll be ok.

you can run lower pressures. that'll warm them up too.

I use this on the scrubs that I buy, it is worth a try.

C5inWV is right on when he says, “most likely sign of age would be sliding/loss of traction due to hardening”. Catastrophic failure is not a high probability. To make yourself feel more comfortable, call Hoosier at 574-784-3152.

I picked up a new set of RS03s for the rear (from a local guy) and will use a new set of R6s for the front. Shouldn't be a problem.

Be aware that the R3SO3 needs to be at 40-42 PSI hot, and the R6 wants to be around 30-32 hot. They are both round, black, and say "Hoosier" on them but otherwise, they are from another planet.

Be aware, put the fresher tires on the rear, and the older ones on the front.

I wouldn't drive it otherwise.

Thanks! I'll adjust my tire pressures accordingly. Mike

Eric, what size wheels are you using? Would you be interested in some 315-17 Kumho710's cheap?

I have a set of 17x10 17x11 CCWs. I'm barely scrapping by to make it to Atlanta as is. I would love to have a set though. PM me a price. I will see what I can do.

Thanks,

Eric

Well thanks to Jason, I will be on 710's for the event. Thanks again man
