Wheels and tires, What to do... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I get the '70 C10 home, one of the things that I want to change is wheels and tires. Please give me some ideas for front and back wheel sizes. I think that I am going to go with 16" wheels. I want the truck to have a nice stance. Nothing too narrow if you know what I mean. If you also have pics as examples that would be great.

Thanks,
Tony

This is just a shot in the dark cause I don't know what look you are going for, lowered or what, but if stock height you can fill up the wheel wells nicely with a 245/75/16 on a 7 inch rim with about 3.5 to 4 inch backspacing, or a little wider but same height a 265/70/16 on a 8 inch rim with about 4 to 4.5 backspacing. Or run the 245/75 on front and the 265/70 on back. Those are common tire sizes that are cheaper too.

I am running Wheel Vintique wheels on mine...15x8 on front, with a 4-inch back space. Back has 15x10 with a 4.5-inch backspace. Front tires are 245-60's. Rears are 275-60's. Running hot rod trim rings and police car caps on the 'Vette-style rallye wheels. Summit Racing has 'em.....free shipping, too.

I found that running anything wider than a 7-inch wheel on my truck front end, was not good. I have ECE disc conversion and the 8's I had, with a 3.5 inch back space caused the wheels to move out too much. The backspace is the key, to good aesthetics.

hey green machine, sounds like you know your numbers and maybe can help. 68 long fleet. i have 8.5x20 wheels with 5.5 bs tires are 275-55-20 aprox. 31 inch tall thinking about 3/5 drop. how far is my backspacing off front and rear? i cant mount wheels untill i machine out centers. i reilly am stuck on these wheels and tires. can you help?

**Green Machine** · 08-05-2006, 01:18 PM

Ok, depends what year you have, 5.5 is a lot of BS, but if you have front disks and the rear end is late 1970 thru 1972, they are about 3/4 inch wider front and back than the earlier all drum setup. If you have the wider axles you might be OK. There is a pic of a blue truck in the wheels/tiires thread above that has 17 inch Impala wheels 8.5 wide with 5.125 BS and I think it looks OK, but it might be stock height.

thanks green machine. i have stock 68 drum/drum set-up. sounds like it wont work out with-out some changes. the tire size can still be changed since i have not mounted them yet. i cant mount the wheels untill i find out how far to machine the center bore out, nobody seems to know and i dont have access to the truck right now. if i find out the correct bs i will have 6 to 6 adapters made not spacers. i am set on 3/5 drop and these 20 in. 07 tahoe wheels. trying to get things ready before truck arrives. so thanks for any help.
