wheel and tire combo help
 

I'm going to be using the Ridetech Street grip system, which Ridetech can't tell me what the complete amount of drop is going to be. So this leads me to my question. For anyone running a Ridetech Street Grip system or a drop near 4/6 I need your help. I'm wanting to run a 20x8 or 20x8.5 in front and a 20x10 rear. Tires will be 245 or 255 40 series fronts and 295/40 rears.

I need to know what back spacing your running and pictures would be awesome.

Thanks for your help!

20x8.5 front, 5.25 BS, 245/40R20
20x10 rear, 5.5 BS, 315/35R20

I think my drop was 5/6. No rubbing anywhere.

I want to try a 275 in the front, for looks and for handling. Between the wider tires in the back and the iron headed big block the front end wants to push through turns.

I have 3.5 drop on front and flipped springs on back with about a 1 inch spacer for rake I have 275-40 20 on front and 305-50 on rear on riddler wheels

Good-looking truck. do you know if you would have room to go to 5 inch or 5 -1/4 inch backspacing on the rear?

Not with 315s, I wouldn't think there's enough room. 5-1/4 might fit with 305s, probably with 295s.
