My Tercel is going to need tires soon and while shopping around I discovered these. They’re available in 165/80R13 and I currently run 155/80R13. I work on a 100 acre complex that is all gravel, have a 1/2 mile gravel driveway and run several errands on gravel. The average little P series 13” tire doesn’t hold up great especially with the full trunk of tools I carry for work. The size difference is negligible and the speedometer accuracy could be challenged anyway in a 28 year old car. What do you guys think? I probably put 100 miles a week on it anymore. I should also add that I run back and forth to hay and farm equipment on our farm almost daily with it too. Nothing really harsh, mostly hay fields and maintained private gravel roads.
