I have a 6" RCD lift, currently 35" mud grappler tires on 18 moto metals.. i posted to craigslist for a 1 for 1 trade. I wanted wheels with less backspacin (more in the wheel well) and all terrains. A guy offered his 20 steel chrome with 37" bfg all terrains. could i fit these monsters? and how bad will these humongous things suck my mileage ?

 

if the backspace is close to stock, you may be able to fit 37's. as for gas mileage, it would all depend on your gearing.

 

ask eff 150

he put 37" on his 6" lift and they fit. said they rubbed pretty badly though.

 

if he is trading you steel chrome he also better be giving you some cash ontop of it. Steel chrome wheels are worth nothing and are heavy as sin!
