What size tire for 15x8 Truck Ralleys - The 1947 - Present Chevrolet & GMC Truck Message Board Network

txsilverado · 04-27-2010, 01:16 AM

I bought a set of 15x8 ralley wheels to put on my 72 long bed Cheyenne. I am looking to get a set of wider BFG tires to make it look a little sportier. What I am asking is what is a good size tire to put on it that would represent a period correct aftermarket setup. I looked at a truck that had 235/70-15's on it. They looked a little skinny for what I am trying to do. Any ideas?

Heres 4 pictures taken today of my 72 GMC.
I'm running:

Front 215/70/15
Rear 275/60/15

255/70 front, 285/70 rear

Tx Firefighter · 04-27-2010, 06:03 AM

I think the 275/60 is the perfect tire for an 8 inch wheel.

LMN8UR · 04-27-2010, 06:15 AM

I'm running 255/70's, the outside diameter is pretty close to stock so the speedo is semi accurate.

GKsport67 · 04-27-2010, 07:33 AM

245/60's all around

**lks dcvn** · 04-27-2010, 08:23 AM

I agree on the 275/60 - I have them on all 4 corners.

71meangreenc10 · 04-27-2010, 09:04 AM

275-60 all around....longer life when you rotate them.....

Most of these trucks came with L78/15 tires which convert to the 235/75R15 radial tire.

P235/75R15 is 28.88 inches high with a 9.25 inch footprint

P235/70R15 is 27.96 inches high with a 9.25 inch footprint

P255/70R15 is 29.04 inches high with a 10.03 inch footprint

P275/60R15 is 27.96 inches high with a 10.08 inch footprint

If you want to fill in your whellwells more I think the P255/70R15's are the way to go. You have a little wider tire than stock and a fuller wheelwell especialy if you use an 8 or 9 inch rim.

Jim_PA · 04-27-2010, 12:37 PM

I have 295/50's on mine, but also think the 275/60 is hard to beat. I will be switching to that size next time around.

I just did a rotation. Man, the rears usually don't wear out faster than the front on my other vehicles

X 2. I think the 215/70 is perfect for 7" rallye wheels.

crm318 · 04-27-2010, 03:20 PM

Another one for 275/60/15s on all corners.

PanelDeland · 04-27-2010, 06:56 PM

Here's a pic of 235/70-15 fronts and 255/70-15 rears.I also have a 2 1/2 front 4 rear drop.I will do a wider tire next time but until the power steering is installed I wanted to be able to turn it.

57larry · 04-27-2010, 07:10 PM

255/70 all 4 or 235/70 front, 255/70 rear

chevlwb68 · 04-27-2010, 11:13 PM

245/60/15 Front
275/60/15 Rear

That is my fav setup, but really depends on the stance of your truck and the look you are going for.

I'm framing THIS Post.

I always think LESS of my Truck, then other people, and my Wife is always telling me..."You don't realize how nice your Truck is".

Thanks for the "Props".

txsilverado · 04-28-2010, 12:50 PM

Well, the board has spoken. 275/60/15 BFG Radials it is!

They will work much better with an 8 or 9 inch rim as oposed to a 7 inch rim.

blazed870 · 04-28-2010, 04:19 PM

Wwotr - your truck is perfect. The drop/ tire combo is exactly what I am looking for. Can I get the details? Drop spindles?

What kind of paint job? Bc/ flat cc, primer, or something else.

Thanks in advance

It had 2 1/2" Drop Spindles in Front when I got it and the pevious Owner "Torched" the Springs and it rode like a ROCK!

I put a full set of Shortend Springs/Shock from CPP.
I believe I ordered their 3/4 Drop Kit with the Nitrogen Shocks.

Then I added 2" Lowering Blocks on Top of that.
So the FINAL DROP is 5.5" in Front and 6" in back.

The Paint (if you wanna call it that) is just a Black UV Primer.
I don't intend to keep it like that though.
Paint is coming as soon as I get my Settlement (after 4 long years).

Bennett68C10 · 04-29-2010, 08:05 AM

Your truck looks great wwotr, i would keep the paint the way it is, i love that flat black hot rod look plus you don't have to worry about how or where you drive it. I have been wrestling with painting my project bright orange or going flat black, I guess i might have just answered my own question lol.

What width and backspacing are you running on your corvette rallys, that is the direction i'm going with my rim/tire combo.
