Dry rot?

right? Tried selling my E92 wheels on M3F with 3-4 year old PSS tires and everybody acted like the tires were about to explode the next day like a dead necrotic whale washed ashore and cooking in the sun for 5 days.

My E46 continentals are 10 years old now and have 4K miles on them but still look intact and I drive it on the freeway every now and then. Mind you this includes 5 years of storage in freezing midwest. I’ll be replacing them this summer.

So yeah tires don’t automatically go bad after an expiration date like milk does. Sure you have to replace them but not at the intervals greedy manufacturers come
up with to line their pockets with more money and save their butt from a major lawsuit.

Agreed. My Michelins are five years old and soon to be six and the tires are completely fine, no signs of dry rot or anything else remotely negative. Grip is fine in heat. Car is stored indoors and always has been. Now if I sold them it would be at a steep discount, prorated if you will.

Guys this isn't a street tire, but an R compound. It's a vastly different beast than a 10 year old Conti street tire.

These tires will 1) not grip 2) be unpredictable at their highly marginalized limit due to age 3) be unsafe due to understeer changing to sudden oversteer with very little predictability.

They'd be fun in the right hands and with the right amount of room between your car and an FIA barrier, but otherwise, not worth running these on the track. I have a stack of old but barely used R compounds that are completely worthless for any duty other than holding the car up.

I know, my reply was strictly geared towards people's irrational fear of a street tire hitting some magical "cut-off" date. I inspect my tires thoroughly every few months to make sure I'm good.

Ok, I understand what you meant now. Thanks, will get a new set after I remove tires and rattle can the wheels gold.
