Tire size help please - The 1947 - Present Chevrolet & GMC Truck Message Board Network

tech1 · 07-19-2004, 07:41 AM

I'm still working on my 6 year frame up resto. I have installed a 3/5 drop with springs. I am trying to get the tire size I need. So I can get the right speedo gear for my tranny. My truck is a 70 c10 short step. I want 17" but still want some good rubber on the wheels. I was think about 265/60/17 in front and 285/60/17 in back. Will they fit and what should I run for a back space? Thanks for the help guys

I have run three different 17 inch setups.

My absolute favorite has been 275/50/17 in back and 255/50/17 in front.

The rears will be 28 inches tall, which is stock height for these trucks. Front will be 26 inches, which fits real well under dropped trucks.

I have run these sizes on trucks from 2/2 drop all the way down to 4.5/6 drop. Hands down best setup I ever had. Plenty of meat to where you don't bend wheels or anything, yet looks right. If you're intrigued, remind me by taking this thread to the top again tomorrow when I get home and I'll post a picture of my truck with them on it.

Thanks TX that would be great! What tire brand did you run?

Nitto NT450 tires.

Try Tirerack.com or Tires.com for the best deal, then print it out and make your local Discount tire dude match the price.

try looking at the michelin xca's. they are 7.50x17" and very expensive but top of the line tires if you want a comparison. alot of people go with these tires on older 3/4 or 1-tons that may still require a heavy load rating. hope this helps a little.
