PRODUCT USE INFORMATION
As a general rule, the taller a vehicle is, the easier it will roll. Too offset, as much as possible, what is lost in rollover re-
sistance by increasing tire track width. In other words, go "wide" as you go "tall". Many sportsmen remove their mud tires
after hunting season and install ones more appropriate for street driving; always use as wide a tire and wheel combina-
tion as possible to enhance vehicle stability.
Seat belts and shoulder harnesses should be worn at all times. Avoid situations where a side rollover may occur
Generally, braking performance and capability are decreased when significantly larger/heavier tires and wheels are
used. Take this into consideration while driving.
Do not add, alter, or fabricate any factory or after-market parts to increase vehicle height over the intended height of the
Rough Country product purchased. Mixing component brands is not recommended.
