Tire Size
To maintain tire safety, purchase new replacement tires that are the same
size and load rating as the original tires or another recommended by the
manufacturer. Look at the tire information placard or on the sidewall of
the tire you are replacing, to find this information. If you have any doubt
about the correct size to choose, consult with the dealer. “ST” tires ARE
NOT automotive tires.
Tire Tread
The tire tread provides the gripping action and traction that prevent your
vehicle from slipping or sliding, especially when road is wet or icy. In
general, tires are not safe and should be replaced when the tread is worn
down to 1/16 of an inch. Tires have built-in tread wear indicators that let
you know when it is time to replace your tires. These indicators are raised
sections spaced intermittently in the bottom of the tread grooves. When
they appear “even” with the outside of the tread, it is time to replace your
tires.
Tire Balance and Wheel Alignment
1. Balance - Since it is not legal to ride inside of an RV, except fifth wheels
in most states, it is rare a trailer tire requires to be balanced. Balance is
achieved by positioning weights on the wheel to counterbalance heavy
spots on the wheel and tire assembly “using” a balance machine.
2. Wheel alignment adjusts the angles of the wheels so they are
positioned correctly “toe out/in and camber” relative to the frame of trailer.
Both will maximize the life of your tires.
These adjustments require special equipment and should be performed
by qualified and fully trained technician. These 2 items are not covered
by warranty.
Tire Fundamentals
Federal law requires tire manufactures to place standardized information
on the sidewalls of all tires. This information identifies and describes the
fundamental characteristics of the tire and also provides a tire
identification number standard certification and in case of a recall.
On each tire is a serial number, beginning with ‘DOT’, 4 letters or numbers
giving location of manufacturing plant and last the date of manufacture,
0816 says it was built 8
th
week of 2016.
Other information is size, ply rating, load capacity, required air pressure,
plus much more.
Each original tire installed on a KZRV, has a speed rating of 75 mph
or greater. Please note maximum load rating, tire pressure, and
speed rating is imprinted on sidewall of tire.
