I PLAN ON CHANGING TO 17" WHEELS ON MY A4Q AND WAS WONDERING WHAT THE PROBLEMS WOULD BE IF I GET (GOD FORBID) A FLAT AND HAVE TO MOUNT THE 16" STOCK WHEEL TO GET BACK ON THE ROAD....

the rolling diameter should be relatively close anyway, because of the higher sidewall of the 16 in tire vs. the lower sidewall of the 17 in tire. again, i'd only use the spare for short distances.
