Rims rusted apart so i need a new tire and rim, it has the Carlisle Turfsave 20 x 10.00-8, 2 ply tubeless tires. Their part number of "5111011" I just cant find anywhere that has both a tire and rim for a decent price? Do the tires alone really cost $90?? And could i put a bit over sized tires without an issue(of course if they would fit) and would I be able to find these slightly larger tires cheaper possibly?? Just want to know if theres anywhere you would recommend that I look for a tire and rim for the best price.
