Tire & Wheel Size for '68 C30

[Troy.Blackburn]

Does anyone have any suggestions for a tire and wheel size for a '68 C30. I know the factory wheels are 16 x 7.5. I'd like to put as much tire in there as possible. I'll be using 10 ply E load rating tires because I plan on using the truck, well as a truck and will be both hauling heavy loads and towing heavy trailers. I'd like to have as much rubber contacting the pavement without going over board.

I'll probably stick with 16" diameter wheels, I know I could got with 8" to 8.5" width, would a 10" width be too much? How much of an offset if any should I be looking for.

Thank You
Troy

Is this a single wheel truck or a dually? If dually, I think I would run 235 85 16 on 6.5" common dually rim. If a single wheel, I'd go with 265 76 16 on 8' rim. Both tires should be around 32" tall.

Thanks for the input, I do appreciate it. It's a single wheel truck. If I were to go with a 16 x 8 rim, what offset should I be looking for? I'm guessing 0 as I think the factory 7.5" wheels had a 0" offset and 8" wheels would only be adding 1/4" either side of centerline. Do you agree? What about going with a 9 or 10" wheel?

Thanks
