Wrong...depends on the ACTUAL tire brand...they all say no, but 275s WILL fit w/no probs.
I run 275/40 Falken ZE512s on my 17x8s up front that match my 10.5s on the rear.
Just FYI...if you want 9s, then by all means, get them. Especially if you're putting them on the rear...they WILL look better on the 9s at the rear!
