I ordered a new Sahara this week..now the waiting games begin..have been doing a lot of research on tires, wheels, etc...a couple questions. How much do the stock 18" Sahara wheels weigh? Nitto Trail Grappler M/T vs. Terra Grappler?? Or another brand completely. 90% road 10% offroad. I was thinking a 33" tire w/2.5 Teraflex Coil Spring lift w/Bilstein 5100 shocks? I have a 3.21 gear ratio. Any advice is appreciated!!
