Hi, My bus isn't lowered but I want the option to lower it like Eric's bus. I got the 15" bus wheels back from the powder coater. Now for some tires. Seems like the narrowest tire I can find that is XL rated is 195/70R15 or 205/65R15. I prefer the shorter sidewall but am worried about rubbing with 205's. Anyone here with 15s and a lowered bus? What size tire? Thanks, Conrad
