TIRE SIZE & TYPE DESIGNATION
For example, the tires on your unit may be marked with a designation of standard trailer (ST) 225/75R15 or light truck
(LT) 235/85R16. The designation breakdown is as follows:
• The first three-digit number gives the width in millimeters of the tire from sidewall edge to sidewall edge. In gener-
al, the arger the number, the wider the tire.
• The next two-digit number after the “sash” mark, known as the aspect ratio, gives the tire’s ratio of height to width.
• R — The “R” stands for radial.
• The ast two-digit number is the wheel or rim diameter in inches.
MAXIMUM PERMISSIBLE INFLATION PRESSURE
This number is the greatest amount of air pressure that should ever be put in the tire under normal driving conditions.
SPEED RATING
• Typically tires with a ST designation are speed restricted to 65 mph under normal infation and load conditions.
• Typically tires with a LT designation are speed restricted to 75 mph under normal infation and load conditions. Do
not exceed these speed ratings regardless of the posted maximum speed limit.
Tires are warranted by the tire manufacturer, not by Vanleigh RV.
If you need tire warranty assistance, please contact your dealer or refer to the tire warranty pamphlets provided with
your RV.
TIRE TREAD
The tire tread provides the gripping action and traction that prevent your vehicle from slipping or sliding, especially
when the road is wet or icy. In general, tires are not safe and should be repaced when the tread is worn down to 1/16 of
an inch.
Tread wear bars are raised sections built into the bottom of a tire's tread grooves that show how much tread is remain-
ing. When they appear “even” with the outside of the tread, it is time to repace your tires.
The Penny & Quarter Test. Pace a penny or quarter upside down into the tire groove. If you can see the top of Lincoln’s
head, you are ready for new tires. If you can see the top of Washington’s head, tires are OK but close to wearing out.
