how wide can you go
 

Its time for new wheels and tires for my 70 c10. The truck is a project street and strip toy. I am curious how wide I can go in the rear on the stock width axle and trailing arms. I don't mind cutting the bed I just want to avoid narrowing the axle or any complicated suspension modifications at this time. Truck is stock height at this point but will probably end up with a 4 inch drop or something in the neighborhood.

Re: how wide can you go
 

you can put a huge tire under there you will just need a wheel with a ton of back spacing. I'm sure some one on here can tell you the actual width and wheel size. I know Hart Rod had a pretty big tire and wheel on his farm truck.

Re: how wide can you go
 

mine are 295/50/15 on 10"

Re: how wide can you go
 

That's what I had on my last truck but it was a 78. I want to go bigger like in the 14" or maybe a little wider if possible. If anyone can post a setup with Wheel dimensions bigger than 295/50 on a 15" wheel I would like hear about it. I was looking at the wheel vintiques 15X14 rallys but the back space doesnt seem anything close to what I need.

I think you need like 7.5 inches of back spacing on a 12 inch wheel. I know you can fit a bigger tire than a 295/50/15.

Re: how wide can you go
 

what about the biggest on a step side without cutting the bed?

Re: how wide can you go
 

I don't know how wide these were but the frame wasn't modified.

Well here is what my truck had when i bought it they were 14'' wide wheels with like 9.5 back spacing with 15'' or 15.5'' wide m/t sportsmans on it nothing was cut other than the bed.I woupd think this about as wide as you can go if i remember corectly there was only like an inch or two from wheel/tire to springs.

Re: how wide can you go
 

And djracer you'r right it's 7.5 back spacing for a 12'' wide wheel thats what i am running on mine now 12'' wide welds with 7.5 back spacing with a 325/50/15 drag radial.

Thanks for the info that was kind of what I was wanting to see.

You'r welcome

I'm runnin a 28x11.50 on a 10" wheel with 4" backspacing. Took a little bit of hammerin on the inner fenders to make it fit

Re: how wide can you go
 

Dad is running a 31"x18.5", only mod needed are than widening the wheel tubs and cutting the bed to fit said wheel tubs is finding a narrower spring.

Re: how wide can you go
 

The widest I could fit with stock tubs was a 15x10 with 5 inch backspacing and a 315/60 Drag radial. Truck was lowered 6 inches in back.

390/45R15 on 12 inch wide rally wheels.
Plenty of suspension clearance but the parking brake cable almost rubs.

Re: how wide can you go
 

What backspace on the teal truck?

Re: how wide can you go
 

the backspacing is 8". I widened a 15x8 by 4".

Re: how wide can you go
 

I did the same thing as Doug...I sent out a stock rally and had 4" off back spacing added it was like $50 a wheel...I have put the 31x18x15 M/T's on them with no issues except I had to relocate the E brake cable on the trailing arm.....I can't say if it will clear a stock spring since I'm bagged...but they do clear the outside ( bearly) dumped with a C notch....

I can't figure out how to move pics from my build and since I lost the old puter with the pics I can't repost them..but they're in my build including what I did to tub it

Re: how wide can you go
 

Doug - if you use the parking brake cables from a leaf spring truck, you will have plenty of clearance for your wheels.

I'm running 20 x 12's with a 7" BS (67-70 rear end). The tires are MT 31 x 16's.

Re: how wide can you go
 

Mine was originally a leaf truck.
What's different on a coil truck?

Re: how wide can you go
 

They are longer, which allows you to route them away from the wheels.

I know this thread is a little old but what combo did you wind up goin with? I'm lookin to do about the same on my '69 short fleetside & want to run a 14" wheel.
