Tire Repair
The proper repair of a punctured tire requires a plug for the hole and
a patch for the area inside the tire that surrounds the puncture hole.
Punctures through the tread can be repaired if they are not too large,
but punctures to the sidewall should not be repaired. Tires must be
removed from the rim to be properly inspected before being plugged
and patched.
Tire Fundamentals
Federal law requires tire manufacturers to place standardized
information on the sidewall of all tires. This information identifies
and describes the fundamental characteristics of the tire and also
provides a tire identification number for safety standard certification
and in case of a recall.
Considerable quantity of information is built into the sidewall of tire,
such as size, weight capacity, air pressure allowed serial number
and where it was built.
The letters “ST’ refer as “service trailer” tires used on most RV’S,
manufactured for that purpose and not for automotive.
Tire Speed Rating
Each original tire installed on KZ RV recreational vehicles have a
speed rating of 75 MPH or greater. Please note maximum load
rating, tire pressure and speed rating as imprinted on the sidewall of
tire.

specified on the placard. The combined weight of the cargo is
provided as a single number. In any case, remember: the total
weight of a fully loaded vehicle can not exceed the stated GVWR.
Water and propane also need to be considered. The weight of fully
filled propane containers is considered part of the weight of the RV
before it is loaded with cargo and is not considered part of the
