Rules vary by location and change. A listing here means the business published the fit info shown, not that we guarantee your rig fits. Call ahead.

Chain size rules: who says yes or no to duallies and RVs

What each chain publishes about dual rear wheels, RVs, height and width. Blank means the chain doesn't publish it. Individual sites can be stricter, so call ahead.

Tommy's Express

Calls itself dually-friendly. Conveyor belt does not grab the wheels. Asks drivers to disengage 4WD and secure loose bed items. Two official pages give different maximum widths; we show the stricter 96 in.
