Got my near NOS L60's from Donny about 4 years ago. I am NOT afraid to drive it basically anywhere. If you are apprehensive, run tubes. I agree some used tires are really bad. If I was going to beat the snot out of the old girl everytime I drove it I would not spend good money on ANY used/NOS tires of anykind. Just go buy the Mickey's or Pro-trac's if that is the case. They will twist the ears off any Muncie!
