I’m not going to comment about tire size too much.
What I do want to comment about is be sure to look at the tire manufacture date – which is stamped onto one side of the tire (inside or outside). If tire was made after 2000, it will have 4 digits stamped into tire, just after the DOT number.
Examples:
35th week of 2007 (WHICH ARE TOO OLD)!
13th week of 2017 (these would be good to go).
Tires are not safe to drive on after they are 10 years old (or 7 years in hot areas like Phoenix). Look at that tire stamp before purchasing! I wouldn’t purchase them if they are 8-9 years old (unless you are looking for the wheels, as well) – unless they were a steal.
Most of the tires I see for sale at a bargain are typically not safe to drive on.
