chart for all max tire sizes on a stock vehicle and lift needed to fit certain size tires.. check it out

http://www.truckaddons.com/Catalog/s...wheel_list.htm

 

it's not very accurate though. it makes alot of assumptions. like most people that don't know 4runners would say you can't put 285/75/16's on a lifted 3rd gen, 4wheel parts didn't even know how to lift mine and I had to tell them the model number for the SAWs to order me and the model number for the OME springs too.

 

there is no mention of 31" tires fro a 1985 toyota pickup 4x2

i have 31s now and they still dont fit... i have a 4" suspension lift with cranked a little higher but not maxxed out t bars..... the tires still rub the inside rear corners of my front wheel wells...
