that was my goof on the 25 inch rim

I really do have 15 inchers. The tires I got now are Kelly Chargers and i think i paid 65 bucks a piece for em. But they wore down to quick. BFG is a good brand name but i would hope they wouldn't wear down so quick. Does anybody know the biggest tire i could fit under a 3/5 coil spring drop with 8 inch wide rims. I was thinking them 275 60 15's would be the biggest but if anybody else knows otherwise pleaseeeeeeeeee let me know. Thanks!!!!!
