Title: Need help with backspacing and wheel size
Post by: chevyman350_82 on February 20, 2018, 10:47:24 am: I have searched the web for hours and I am more confused then ever so sorry if this is a repeat question but I know every truck is unique so thats why I have to ask...

I have a 82 c10 lowered 3/5 with half of rap cut off front springs I currently have 15" rims and looking to go up to 17" I would like to have the largest lip possible on rear and just standard 8" wheel up front and either 9.5" or 10" wheel in the rear.

Current wheels 15"x8.5" on 265/50/15 and it does not tuck but its close so I would like to keep it close to the same stance until I can go air ride.

In a 17" wheel what is the backspacing I would need up front and backspacing for largest lip as possible in the rear.
