Nothing wrong with going 9.5 in front and 10.5 or 11 rear. Do you really want to go that wide (10.5 and 12)? That makes for really thick tires too...a lot of extra weight and tramlining on rutty streets. Something to think about. You cqn run 255-285 on 9.5 front and 305 or more on 11 rears. I'm just saying...
