What is the widest rim and tire combo i can put on back of 64 c10 without narrowing rearend?

Fleetside... assuming you have stock rear axle...8x15 275x15 or 10x15 if you roll the inside fender bead.....

thanks for the reply...yes stock width axle shortbed fleetside..i have taken measurements and think its possible to run 12 wide rim with 325/50/15 tires but not sure of backspacing..do you or anyone else know?..also its a 64 assuming the rearend was never swapped for another year..also some pics from anyone would be helpful...thanks :)

Moved the thread plus a bump to the top.

I have a tubbed stepside, but your fleetside may actually have a bit more room on the outside. 15x12 with a 325/50/15 et street. The backspacing is at 8.5"

Most rim shops don't like backspace that large, you usually have to ask, but I have seen them up to 9.5" of BS. That would be nuts to me. 8.5 is really pushing it, and (at least with a steel sectioned wheel) narrows the center of the barrel, so brake clearance become very tight. A big part of fitment is the tire choice, if you want to run a non-radial, you might want a bit more clearance. The ET street radials I run have surprisingly little "bow" out under the weight of the truck. I have about 1/2" or so on the outside, and could roll the fender a bit if I needed to.
If you want to go that big, you HAVE to remove the e-brake cable from the drum. It interferes with the rim

thanks for the info... i have found some wheels from centerline and weld with b.s. that will work but of course in 5 lug which i plan to swap axles from early classic enter. later on..i ran the mt et drags on a mustang i had and they did ok, but for the truck i was looking at bfg drags for it and yes they do balloon a bit more though and my e-brake cable is already removed...i guess i really need to take more pricise measurements and research my tire options a bit more...just wanting a good looking wheel and need that traction width!

I'm running the stock truck rallys 15x8 with 305-50r-15's on back without any problems .. Once they are wore out I will be switching to the 275-60r15 tires ..

Re: Wide tires

Re: Wide tires
 

I'm running 15"x8" with 4" backspacing and my wheels are perfectly centerd with about an inch on eather side. P235/75/R15 tires.

Cut the rear end 4" on each side and installed new ,Moser axle's. These are 15"wide mickeys Thompson's tires on a 15 x12 rim with a 6.5 back space. Did cut the bed and use fleet side tubes in the bed.
