I want to increase to a 285/75/16 tire and currently have 265/75/16 with out doing a lift. Tire tech says it won't work on my truck.

I have 1 1/2 inch clearance between tire and fender @ it closest point. Will it work or not? Has anyone tried it yet on a similar truck?

In my garage ...I have several pix, but have not figured out how to upload pix to this post yet.

 

is it a 4x4

 

if so just crank on the torsion bar bolt until you level your truck and stick them on. there is a ton of adjustment on those trucks my 92 i had gave me almost 3 more inches for free just by turning up the torsion bars

 

I don't know if I am comfortable in doing that. The truck is not a 4 x 4 but looks like one as it sits high already. Knowing that it can be raised higher w/o modifications...I increased the tire size.

My calculations leads me to believe that going from 265 to 285 in tire size would increase the tire tread by one inch...which leaves 1/2 inch clearance.

Am I right or is my inclinations out of balance?
