Tires
I bought the same tire (19.5, Mich) and got them from Discount Tire. They are not cheap, but Discount Tire was the best price I could find. Still cost me over 1,000 bucks for 4 of them. Guess I look at it as the tires are the only thing between me and the road and my (and family) safety is Number 1. You can cut some costs in other areas to make up for the higher price of tires.
