The usual tire size question......Please help an idiot out..... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Please help me out on this guys. Just picked up a set of 17x9" wheels with a 6 inch offset. Hoping to run them on my '79 2 wheel drive with no drop. May drop it later but will be a 2" max. What would be the best tire size for me to run. Looking at possibly going with a 275/55/17 but I'm not sure. What is everyones opinion on this. Thanks.....

Use this calculator to see how the tires stack up against each other.

More importantly....

Frank, would you have room to go another .500" toward the center of the truck? I know my 74 was very close (too close) @ 5.5"bs. I don't think 6"bs would work w/o spacers.

Same on the front.... I had 8's w/5.25"bs which required a fairly healthy shave of the lower a-arm lip. 6"bs would require the same, & then some.

I run 315/35/17 in the rear and 275/45/17 in the front. I have shaved a small amount from the lower a arms and installed wheel spacers. They have never rubbed and ride good.

You are right about the rear . I would never go any more than 5.5 backspace in the rear unless I was going to use a spacer . The fronts clear the a-arms fine but I only use 2.5 Western Chassis spindles for that reason. Once you go to 3 inch spindles you have clearance issues.
