Talk about a low,low budget lift:rotflmao2:

the inch gain in overall diameter will only "lift" the vehicle 50% of that. So .5inches more ground clearance.

Well, you're only effectively going to get 1/2 of the increase in tire diameter in actual "lift".

Only the half of the tire below the axle is able to "lift" the vehicle.

So, yes, 33s will be better than 32s but, not sure you'll notice a big difference in 1/2 inch of lift.

Guess Goody beat me to it.
