It's time for new rear tires on my 08 Silverado. 2 yrs old, but tread depth is getting a little shallow.
The question is in regards to the spare. "brand new" 9 yr old oem spare that's never been on the ground. (it was under the truck all this time until I took it out last Nov and put it in the bed). The oem spare still has 32psi of original nitrogen mix in it. I'm concerned about dry rot on a tire that old if I ever really have to put it on.
Am I better off putting one of the 2 year old tires on the spare rim and just chunking the 9 year old tire or keeping the 'new' oem tire for the spare?
