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...
My spare is slightly different size. But in 9 years I have never rotated my trailer tires, and my spare has never been on the ground. But it will be fine to get me to a tire shop if I have a flat.
Of note, my tires are not 9 yrs old. They have been replaced. And spare was replaced when I picked up a slightly used, almost same size, tire 3 yrs ago.
