So....I have a set of Raptor wheels on my truck. They have a 34mm offset and my stock wheels had a 44mm offset. Does that mean my tires are now 10mm further away from my UCA? Backspacing is 6.16 compared to 6.5 stock? Basically I just want to know how much further away from my UCA I am now with the switch to Raptor wheels.

 

Widths play a factor as well. Raptor wheels are 8.5 inches wide. How wide are the other wheels? Are u just wondering or what are your intentions? Getting bigger tires?

 

Put in your specs in this calculator to see the differences.

Stock wheels are 7.5 inches wide. I am trying to fit the biggest tire possible without rubbing the uca when turning.

 

Just put 20X9 monster XD with +18 offest, on 35X12.50 TOYO MTs, works perfect, the truck had to get a leveling kit first.
