im currently in the process of preparing my rig for a 4in rough country lift and i am trying to sort through some issues in which i will have to deal with. i have a set of 305/70/17 nittos 34.1x12 to be a little more exact and i already have 17x8.5 atx thugs with 4.5 backspacing i am concerned about fitment and rubbing issues after i lift 4in

 

Contact the lift vendor or look at their install instructions. Some of those bracket lifts list 3.75" or less back spacing on a 15" wheel for proper clearance with the spindle and suspension arms.

 

yeah rough country suggests 3.75 but wouldnt a larger wheel help with clearance

 

That would depend on where the clearance issue is. If a 15" wheel lip is the issue and there is nothing an inch higher up, then maybe a 17" wheel would help, depending on the shape of the back of the wheel and the shape of the part of the suspension the wheel might contact.

See if they have fitment data for a taller wheel or find someone with a kit and take a look at the clearance with whatever size wheel they have. At the worst, you might need to add a wheel spacer, a 1" spacer would give you a net 3.5" backspacing.

 

k and what brand spacer would you recommend

 

Lots of place have them, Performance Wheel is what I have, All Pro Offroad, Trail Gear, Marlin Crawler, etc. all carry them.

 

any issues with them

 

All the spacers are pretty similar. The ones I have work fine, bought them used so did not really have a choice in brand. Only thing I had to do was slight grind down by lug nut socket to fit inside the spacer holes to put on the stock lug nuts. On some spacers, I think you may need to use special lug nuts, so be sure to check and get those if needed.

 

sure will, i will be buying a new set and im in between all pro and spidertrax leaning more toward all pro because i can't seem to find spider trax in anything less than 1.25in, so all in all 8.5 in rim with 3.5 backspacing counting spacer with 12in wide tire should fit and look great thanks for the insight 4crawler.

 

Could always install the lift then test fit the wheel on the front and if it clears, run it as is. If not order up the spacers.

 

yeah but it could cause a delay in getting my dd back on the road lol and yet i don't think i would mind the 1" spacers would give better stability
