Will They Fit

I have an 09 doublecab prerunner. I would like to install the Ivans 16x8 with 275/70/16. Also install the 5100s to level the truck in the front. I did some searchers and people say 265/75/16 would work better. The 275 is a little bit shorter but also wider. Would the 275 rub on the internal parts? I like the wider tire. Any thoughts or help? I also have added the tire chart with both wheels.... Thanks...

hmm... not too sure.. what's the backspacing of the IS??? 4.5? If so, me thinks you'll be OK and clear the UCA. If not, wheel spacers would always help. You might have to trim some of the inner fender plastic, but that's no big deal really...

 

Not sure but I think it is 4.5 backspacing... Thanks..
