I like the Goodyear Viva II from Walmart. They will take higher air pressure and I put 44 pds of air in them. My mileage went up from 45 to 50 mpg. I went with a 175 75 13 on my 85 Jetta. I tried to use the original 155 80 13 in a Douglas, but they pulled every which way and I was glad to get rid of them.
