Suspension Question

[RUfj40crazy]

I am rebuilding a 76’ 40. Currently running a 15x10 rims and 31x10.50 tires with stock suspension. I however would like to put 32x11.50 BFG AT’s on it.

First: Any body know will the larger tires fit ok without excessive rub? I know they fit the rim.

Second: If they do rub (probably would) what are my best options? Keep in mind I have a very limited budget. What ya think? Lift? Spring over?
Thinking of spring over but not sure of what all should be changed to ensure good drivability.

spring over is gonna entail a lot of work and some $ for parts needed. id' say get some good measurements on the tires and room between them and the body right now, especially at full turn in the front and the front side of the rear fender well. going 1 inch bigger ain't much.
why are you running a 10" rim? how about going with an 8"?! might help the rubbing and you can air down way lower without having to worry about popping a bead.

Came that way with the 10's, Ive only had it 2 months and its been in parts since. Just workin with what Ive got.

Can you elaborate on the spring over any or direct me to a link where I could study it more? Im pretty mechanically inclined but this is the first truck, my experience is mainly with sport bikes and the two wheel variety.

The 32s should be fine. On the front end, you might rub a bit on the drag link, but no biggie. While I would prefer 8" rims over the 10s, the 10" width will actually help with the rubbing since it effectively moves the centerline of the tire tread outward.

On the rear, the wider rims will probably put some sheetmetal in harm's way. It's time to trim those fenderwells if you rub. That's about as cheap as it gets.

No need to consider a spring-over unless you're planning to run at least 35" tires...

if $$$$ and time is not a problem go with the spring over.look in the tech forum for all the info. good luck.
