1. Tyre Size Designation
On all 4x4 tyres there will be an LT in front of the tyre size if the tyre
is of a reinforced construction. LT means light truck (reinforced). If there
is a 'P' or no lettering at all, then it will be a Passenger tyre type. We
strongly recommend fitting the same type of tyre on all four corners of the
vehicle, fitting different types of tyre on the same vehicle can cause
issues with the vehicles handling characteristics. The 235 is the nominal
width of the tyres cross section in millimetres. The 85 is the aspect
ratio - the ratio of the side wall height to the cross-section width. The
R stands for radial-ply construction. The 16 stands for diameter (in
inches) of the wheel that the tyre is designed to fit. Always ensure that
the tyre fitted has the correct or higher load/speed rating as specified for
the vehicle. It is not recommended to mix tyres with different load/speed
ratings on the same axle.
