Re: Biggest rear tire size???
Give Jon from DriverzInc a call, he'll hook you up (and educate) as he did me. 275 tire is the widest you want on the rear while 225-235 for the front. Some have gotten away with 245 up front but IMPO, you're gambling at that point (more like asking for trouble). The second number (sidewall size) 60, 50, 45/40 will depend on wheel height (16, 17, 18 inch). Generally but not always, the taller the wheel the thinner the sidewall of the tire as you donít want 18 inch wheels with fat (60 series) sidewalls as that wonít fit and will look awful. Also, you must consider the wheel width (17x7, 17x8, 16x9, etc) You can run 275 tire on 15-17 inch wheel as long as the wheel is wide enough (but not too wide) to support that tire. Backspacing is probably the most important part because if you get that wrong than itís game over. Better to have too much backspacing than not enough as you can fix too much backspacing with a cheap spacer while not a whole lot you can do with too little backspacing. I run 18x9 with 5.25 BS on 275x40 tires in the back while 18x7 with 4.25 BS on 225x45 tires up front. See sig for pictures.
