C20 Tire Size - The 1947 - Present Chevrolet & GMC Truck Message Board Network

70chevytruck · 01-31-2013, 12:58 PM

Pictures and sizes of tires on C20's....Just picked up some F**D 16x8 Wheels and need to see what size tires look good!

Also tire pricing...man they have gone up since I have bought some last....Where and what brand is the best?

Bought tires for my 07 GMC at Sam's Club and they were a great deal..maybe need to go back!

Thanks,

I was thinking 275/75/16.....thoughts?

**jocko** · 01-31-2013, 03:26 PM

i like 265-75-16 as a good choice for a c20 - here's a pic:

**MidLifer** · 01-31-2013, 03:29 PM

My "heavy 10" (c10 into which the PO swapped a 20-series driveline) has 235/85/16s. I kind of like the extra height of the 85 profile.

Cheapest tires I've seen in that size run about $160/ea.

k2rm · 01-31-2013, 04:23 PM

I went for a staggered look.

245 75 r16 in the front
285 75 r16 in the back (10" wide)

Sicklajoie · 01-31-2013, 06:40 PM

265/75/16 here
They are the same height as 235/85/16 and an inch taller than 245/75/16
I've got 16 x 7 rims. The 265's should still look good on your 16 x 8 rims. The 235's might be stretching them a little on a wider rim like what you got.
I went with an expensive set of Michelins ($850 for a set). They're worth it though. The sidewalls are soft which makes for a great ride and they wear like hockey pucks so they'll last a long, long time.

70chevytruck · 01-31-2013, 06:55 PM

Thank you all....sounds like 265.75.16 is the way to go.

Here is my C20 on 265/75/16 Michelins

Sideways · 01-31-2013, 08:09 PM

I run Michelin LTX M/S in a 275/70-16 most of the time and a 285/75-16 A/T on the back with the camper.

69Rumbler · 01-31-2013, 08:37 PM

i got 265 75 16 on mine but i need to get new ones..... looking at 800 for the set

daves72C10D · 01-31-2013, 09:15 PM

edit, never mind.

I run 285/70-17 on all 4 corners of my '69 C/20. I like the look.

Dan not to steal the thread but is your truck lifted or is it just the wheels and tire size that raises it? What brand of wheels are those?

Those look like Hummer H2 wheels

They are H2's, I am also interested in whether or not the blue truck is lifted. i have seen some for sale locally with the same size tire on them and was wondering if they will go on the front with rubbing with stock suspension. Lets us know!

When I did front disc conversion I changed out the front springs. I installed some HD springs bought from NAPA. The stock HD C20 springs are as follows:

http://www.napaonline.com/Catalog/Ca...752_0162319756

Part No.: 2771752
No. of Coils: 7.92
Free Height: 12.94"
Spring ID: 3.68"
Spring Load Height: 10"
Design Load: 2950
Spring Rate: 1016
Wire Diameter: 0.812"

The springs I put on from C10, C20, C30 from 1973-83. They are as follows:

http://www.napaonline.com/Catalog/Ca...074_0162301536

Part No.: 2772074
No. of Coils: 8
Free Height: 13.61"
Spring ID: 3.676"
Spring Load Height: 10"
Design Load: 3841
Spring Rate: 1060
Wire Diameter: 0.83"

You could also use C30 mid '80's 1-ton springs, but I thought they would be too stiff. Those are:

http://www.napaonline.com/Catalog/Ca...085_0162304063

Part No.: 2773085
No. of Coils: 7.93
Free Height: 13.34"
Spring ID: 3.65"
Spring Load Height: 11"
Design Load: 3289
Spring Rate: 1318
Wire Diameter: 0.906"

The wheels are chrome Hummer H2 wheels from 2003-07.

I have this exact Q right now. So the 265/75/16s on a 8" Rim won't ever rub? I'm replacing my split Rims w/ Wheel Vintiques 16x8's. Name: IMG_2221.jpg

Yeah, I believe so. My rims are 16x8 with 4.25 backspace and -5 offset. I run 265/75/16s and have never had any rubbing issues.

Do you have a pic of one of your wheels/tires you could post?
