Thank's and I will repost it here These numbers are for stock track width, static dropped trucks.
These numbers are the absolute minimum and will keep the wheel inside the fenders. Your wheel diameter, tire selection and drop will be the desiding factors in whether or not you have to roll/modify inner fenders/lips.
When you're looking to buy a wheel, you will need to know either the Offset or backspacing of the wheel. If you're looking at a wheel and it doesn't meet the specified numbers for it's width, it will not tuck and there's no chance with your stock track width. so this is to help with wheel selection.
The key number you need to assess is the front spacing. it needs to be 4.25" or less. If the front spacing on the wheel is higher than that it will not matter what the backspacing is because it will never tuck
the Categories are the width:
