How can I tell if my tires are getting old? They have about 30000 mi on them. The tread still looks OK. The sidewalls look OK, but I don't really know what to look for. These are Karrier Loadstars.
I don’t take major chances with my TT tires. Not fancy brands, but over capacity for the max load they would ever see. Convesly, my small utility trailer 8 inch tires stay on until they pop or they dry rot so bad that I have to fill them more than once a month. Both are currently about 15 years old, and spare is about 25. But it only goes on short local runs mostly low speed.
