I'm picking up my newest find on Tuesday a 78' 40. It is rolling on 12.50's and after market wheels. I need to know if it will fit on my trailer between the fenders....so does anyone with 12.50's know how wide your rig is sidewall to sidewall. (We will have a built in margin of error for back spacing and tire lugs)

Thanks!

 

width of the rim plays a part...my truck has a wider stance with 10" rims vs 8" rims with a 12.50...
why can't the seller tell you how wide it is?

 

The seller is out of town until Tuesday. He will comeback archer I leave t lick it up. Ad yes it is sitting on 10 inch wheels as well.

 

Wheel Offset plays a part in this also.

 

Mine is on 12.50s on an 8 inch wheel with 3" backspacing I think and it sits at about 70" wide from outside of tire to outside of tire. I just went out and measured for you!!
