Oh! this reminded me.
If it has used tires on it that have no cracks and look fine with plenty of tread, DON'T USE THEM.
When I got my car, it had winter tires that expired in 1999. No dry rot, plenty of tread PERFECT! only need to buy two tires.
Dad talked me out of it, and when the tire shop took them off, all of the skirting? on the inside of the rim was shot. If I even went 5 miles an hour they would have exploded and taken the whole front of the car off and into orbit. (since they were truck tires, they had 60 psi in them)
