The noise from my six-month old Yokohama SV4s are driving me nuts and I'm considering changing tires once more. Thinking about moving to 16 inch rims and tires. What size fits on 90q '93-'95 w/o suspension mods? I know the q has a tight fit. Has anyone done this? Would anybody be interested purchasing my current set of original 15 inch 5 spoke Ronals? TIA, Siegfried
