Wheels and Tires 30″ tire width question December 1, 2015 This might be a silly question, but why do 30" tires only come in widths of 10" instead of sizes like 30×9 and 30×11? Maybe I am just old school and are use to running narrower tires on the front. Share this:Click to share on Twitter (Opens in new window)Click to share on Facebook (Opens in new window) Related
