Just to clarify...33's fit on a stock '05+, the soft skirt plastic is all you move a bit to clear.

As for spares smaller than the rest...bad idea if you off road...as in if the terrain popped your GOOD tires, imagine what it will do to your wimpy spare?

And, if you needed 4wd and 4 big tires to get in, will you be able to make it out on 3 good ones, etc?

The LSD's will send the torque to the smaller tire, as that tire will be spinning the fastest...and your GOOD tire will be along for the ride.

The Or's have less problem, as the stockers are 32" anyway, so the size difference is minimal, especially when aired down....but the locker will be working the axle sideways as it twists it towards the smaller tire, etc.



If you have an '05+, and are getting new tires, get the 33's. If you have a hitch in the way, deflate the spare until it fits, and bring a compressor to inflate it enough to use later (On the trails, you are aired down anyway...)

Just get 5 tires, and sell the virgin spare for maximum ROI.



You could probaly run 305/70/16's instead of 285/75/16's, and get the extra traction and floatation...and just adjust the turn stops a bit to avoid rub on full lock.

The 305/70/16's are slightly wider treaded, and slightly taller, than an average 33x12.5/15....with a slightly narrower section width for better handling and more clearance when turning.



BTW - If you off road with splash guards, they get ripped off, detracting from their looks and functionality....and their resale value if not taken off before wrecking them.

(Same goes for the aluminum steps...they're lovely and all that, but, they get ruined off road, and if you take them off before wrecking them, you can sell them, and buy real sliders that protect the truck.)



I can't tell you how many newbies I've seen tear off the guards and bend/dent the steps...and then wish they'd left them home for e-bay, etc.
