Those look great! I like the black wheels.
Any plans for hydro assist to help move them around? Even with 35” trail grapplers and bead locks on my JLUR I’m wanting a bit more in the rocks

Speaking of wheel backspacing, do you need 3.5 to clear EVO coil overs with the 69" width Rubicon axle. I know you couldn't with the 13.5 stt pros and 4.75 backspacing wheels but not sure what EVO recommends.
Like Eddie said EVO recommends 3.5 BS with "most wheel tire combinations" for the CO set up on the JL.

I have the 4.75" BS wheels with the 1.75" Synergy spacers (3" BS total by my math) and the Cooper STT Pro in a 37 13.50R17 on mine and I am still rubbing the coils at full flex and turn. I have been unable to get out and check clearance to the sway bar links while twisted up but have not noticed any sidewall damage.

So, what I can tell you is that these measure exactly 1" taller than a set of 37" Trail Grapplers. A ground up measurement and with the weight of the Jeep on them, they measure about 36.5". I will try to get a more exact measurement.

I thought there was thread around here somewhere that was supposed to be like an actual tire height database but I couldn't find it... Maybe that was on jlwrangler.com
