Gen 2 - Wheel offset / backspace question
« on: July 16, 2017, 06:25:57 PM »
Just picked up a 96 SR (should be here this coming week). Current plan is to get all the maintenance done and then do suspension / brakes. Since I want to do the 315mm Big Brake upgrade and SS lines at the same time. I will need to get new wheels and tires. Looking to get either a 16x8 or 17x8.5 wheel. What sorta offset and back space should I be looking for? I want to get get 32s on there and widen the track a bit.

I am thinking this combo would work but I am not sure. This is my first time setting up an off road truck.

FN Five 5 Star 16" gunmetal wheels. 16x8 -25 offset 3.52" backspace 108mm hub bore with a Maxxis LT275/70R16 Tire

I believe the wheels you already have (well, stock 1996 SR) are 15x8.5 with a +10 offset,  so if you go to 16x8 with a -25 offset your outer rim surface will be about 1.2" farther out than present and your scrub radius will increase by about an inch.     That's probably OK, but you'll have a little bit more steering feedback on rough roads which will mean a bit more driver fatigue on a long trip and a bit more tendency to understeer if you're really pushing your luck on a curve already.       I wouldn't go dramatically farther than that on offset.
