ok i have a 99dodge ram sport with a 3 inch leveling kit on it from top gun customz and my 265/75/16 look TO sMALL lol could i stuff 35 in it and what kind of back spacing would i need on the rims? and i know i will have to regear.

 

They'll fit, but they'll looked stuffed in there. They will also rub on turns. Not sure on backspacing.

 

ya? i figured those 265 are about 31" so do you think a 33 would be better ? and could i fit a 33 on stock rims?

 

Eh, I think 33's will fit on stock wheels.

285's are a good bet too.

 

285/75 basically ARE 33's.

 

They are slightly smaller.

And surprisingly, cheaper.

 

For this purpose, anything within a 1/4" doesn't really matter.

IIRC, 32.8" vs. 33" No biggie.

 

I have 285's, but No lift. I only have the ORE, which correct me if im wrong, but that's 2 inchs? They look pretty good, fill everything out. They don't rub, but I have about an inch of clearance at full turn.

 

ORE's had 2 in of lift

I don't have a lift.

 

on my buddys truck we did 305/70s with 2 inch spacers. 315/70s wont work with the 2 inch spacers, it would rub on pinchweld.
on a side note with a 3 inch level kit i hope you have a adjustable track bar. you dont have to regear either 3.55s are doable.
