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 in to the side wall of a
tire, such as date of manufacture, size, weight limit tire can carry,
air pressure, serial number, where it was built, etc.
The letters “ST’ refer ‘s to “service trailer” used on most Recreational
Vehicles, manufactured for that very purpose.
.
Maximum Load Rating—
This number indicates the maximum
load in kilograms and pounds that can be carried by the tire.
.
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.
Tire Speed Rating
Each original tire installed on Venture RV recreational vehicle has a
speed rating of 75 mph or greater. Please note maximum load
rating, tire pressure and speed rating as imprinted on the sidewall of
each tire
Beginning in 2017 model year your tires will have NITROGEN in
them instead of air. The green valve stem caps indicate on contents
are nitrogen.
Vehicle Load Limits
Determining the load limits of a vehicle includes more than
understanding the load limits of the tires alone.
On a trailer, there is a Federal certification label that is located on
the forward half of the left (road) side of the unit.
This label will indicate the vehicle’s gross vehicle weight rating
(GVWR). This is the most weight the fully loaded vehicle can weigh.
It will also provide the gross axle weight rating (GAWR). This is the
most weight a particular axle can carry.
