Hi. Consider me a tire newb.

I have been confused of late about the concept of fitment of tires to rims. Can someone please explain to me the long and the short of how well tires are supposed to fit to rims? Specifically, I'm aware as of recently that you can put at 275mm tire on both a 9.5" rim and a 10.5" rim. I am told that the 10.5" would look better, but that it would require some body work I am unwilling to do.

Why would 10.5" look better? I mean, I understand that the tire will occupy more space on a 9.5" rim, but...I don't know where it will puff out. side? tread itself? Also, how comfortably will a Z hold 9.5" rims in the back? is there any chance they'll rub?

Please help!

 

275 is the suggested tire for a 9.5" rim. I think youd be stretching the tread on a 10.5" rim... I think a 295 is better suited for 10.5. possibly even 305.

 

Question #2: ITT explain offset to me!

I do not understand the concept of offset and do not know what offset I iwll need when I get these wheels (8.5" front, 9.5" rear) and tires (245mm front, 275mm rear).
