31s on stock 15' rims

[Srubydo1986]

Well I have 215/75r15 on my truck know with about o 2-3 in of room tell i even start to tuck the tires under the body of my 1986 chevy sliverado 1/2 2wd. I would like to put my tires from a set of rim on the truck, the tire size is 31*10.50R15LT.

My step dad says they will rub i disagree only cause my truck still sits high for a 2wd much higher then my other 86 c10.

P.s. my current tires are the world greatest bfgoodwrinch allterain t/a tires. I need to save money for some new tires cause two of mine are good the rear are bald after to many burn outs.

Ill try and find/ get a pic of the truck know. (it has chrome wagon wheels but same rims size as factory and the factroy ones are going back on it.)

Here's a 2wd I had a few weeks ago with 31's and stock suspension, no rubbing:

[Duro5341]

31x10.50R15 will fit no problem on stock 2wd suspension
accually 32's will fit under a 4x4 stock

The stock 235/75R15 look to small for our trucks, the 31's fill the wheel well nice, and don't rub at all.

We have used this size as a recommendation if changing 4 tires on these style trucks for years at our shop

My step dad keep saying the wieth is to much is he just blowing smoke or is he right?

He says he had a 2wd and tryed putting 31 under it and it rubbed the frame. I think hes truck my have sat lower then mine cause with my old black c10 i think the springs were way wore out cause it sat about 2-3 lower in the front and rear.

Also i used it to haul about 7500 pound about 5 times Kinda killed that truck. This one will be treated much nicer, black one was my first pickup and thought its a truck it can do anything well i was wrong gotta have the right stuff first.

You might have seen it already, but here's a side shot of my '79 C10, suspension is so stock all paint's turned into rust (literally):



These are 32x11.5x15 in the front, and 33x12.5x15" in the rear, there's no rubbing whatsoever. And what yer dad said about the weight being too much - what weight is too much?

I have 275 x 55 x 20's on stock suspension (31.7" diameter) and they clear.

[Srubydo1986]

thoought id show you what the tires look like. Would have liked to used the rims but they are 6 lug and mines a 5.





And hers a pic of my truck before motor installed. didnt go down much.





These have the stock rims im going to use i need newer pics but no film.

I ran 2 sets of 31x10.50's on my 76 with no rubbing at all. One were mud tires, the others were street tires.

I also ran 3312.50's on a stock 86 4x4 so 33's will fit 4x4 and 31's fir 2wd for sure I had it that way. If they rub you got something wrong, worn springs or something.

[Srubydo1986]

ok thing that saves me about 250 for 2 tires fo know atleast.

I've been running 31X10.50's on my 1982 GMC Sierra Classic 1/2 ton stock suspension with 15X7 rallies and have plenty of clearance, no rubbing whatsoever. Not exactly a low rider with those 31's, has worked great for haulin and towin....

great well mines no low rider either as you can see from the pics

[neverfinished]

I'm running 31x10.50R15 on mine too, it's all stock suspension and no rubbing.

[Prerunner1982]

I have run both 31x11.50 and 32x11.50 on 15x8s with stock (except HD front coils) and didnt have a rubbing problem with the 31s and only a slight rub with the 32s on the inner fender and upper fender lip. If there is a rub problem it wouldnt be with the frame it would be with the fender.
