Hello, I am going to replace my cheap Chinese tires ST 235/80/16 E with the Sailun S637 235/85/16 G tires. Question is can I use the current 80 series spare on one wheel and the Sailuns 85 series o...
I like my Sailun and inflate them to around 100 psi. I've got about 12,000 lbs. loaded on 3 axles/6 tires.
Personally if I had a good tire to use as a spare, I would. Unless you're going to rotate the tires. I wouldn't buy a new tire to use as a spare unless I had no good tire.
