rear big wheel question - The 1947 - Present Chevrolet & GMC Truck Message Board Network

yellowGT · 01-22-2011, 10:43 PM

On a 67-72 truck, what is the widest wheel you can run without having to get rid of the trailing arms? Wheels in mind are 22x12 with a 4 inch backspace. Narrowing the rearend is something I dont mind and know it will have to be done more than likely. You guys let me know so I can relate the info. to my brother.

Ive got 22x12 in the rear with ride tech trailing arms and there is tons of clearance. I do have a mini tub but even with stock arms you should have plenty of room.

Mine has 15x10's and pretty big rear tires and its really close to rubbing on the inner fender/bed, with stock rear trailing arms and lowered with springs and a adjustable trac bar.

I'm running 20 x 12's with a 7" backspacing and a 31-16 tire. I'm not anywhere close to the trailing arms. Here'a few pictures:

if you tube it you can run a 15x14 - 10" bs w/ 31x18.5 tire and still clear the arm.. not sure how big ya can go if you keep the stock tubes....

I had a buddy make it for me. It's similar to the ones that FuelCell guy sells, but we modified it to have the sump in the back.

Rob I LOVE that truck! I was wondering, does it still has the narrow rear end?

Thanks, it's got a factory 68 rear end.

What do you have to do to be able to run a 22x12 with a 4 inch backspace?

**mac808** · 04-08-2011, 03:36 PM

Hart_Rod and C10Seconds, do you guys have any rubbing issues on the fender(outer) side of the tire?

I had slight rubbing when I had the wider 71/72 rear installed. None whatsoever with the narrower 67-70 rear end.

c10seconds · 04-09-2011, 05:36 AM

Same here. Im using the 67 rear end and there is no rubbing at all

Sweet! I shouldn't have a problem stuffing in a wide wheel in the rear on my '68 then!

Thanks for the feedback guys!
