would I have to tub out my 1972, - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have a line on a set of 20x12inch rims so my question is dose that wide of a rim require a mini tub or can I run them on stock? The tires on them are 31x16 20 but that dosnt have to stay that way I am more consirned with the rims fitting.

This is actuley what the guy has.
Fronts: 20x8.5 with a 18mm offset. Front tires are General Exclaim UHP 245/40 20 with only 8,000 on them
Rears: 20x12 with a 6” offset. Rear tires are Mickey Thompson Sportsman S/R 31x16 20. Some tread left but not that much.

I don't care about tires I will get new ones but with the rims fit?

I don't think that rim will fit. I'm sure others will chime in but with it being centered that is a lot to the outside. Could not find that tire to look at the section width.

I am not concerned with the tire size because I'm going to put other tires on the rims. Just want yo know if runs will fit and with what tire

The 12" wheel will not work in a stock tub, and would require them to be widened. Also, with that backspace, it would require the rear end to be narrowed.
