Hi, one of my front tire blew up today. I changed it to the full-size spare tire that was stored in my trunk, which is Bridgestone Potenza RE92. It is the same tire that blew up, only being never used - I even pulled some stickers out of it.
The rear tires (probably changed by the previous owner) have a lot of thread left, so I would normally change the front two tires, if I haven't recently bought a couch and a new LCD TV!!!
Would be it okay to keep the spare on and just get one same tire (So the spare and new tire will be on the front) and use the survived front as spare. I searched a bit and learned that tires age but they're okay for 6-10 years depending on the weather it is stored... I live in Austin, TX. Any suggestion?
Thanks,
