Best One Tires of Knoxville

When is RV considered cold for checking tires? 1 Miles or sitting for 3 hours.

What part of tire supports the load? The air When is a tire considered flat? 20% underinflated.

What is the difference between size 295.75R22 and 275.80R22. Virtually the same.

What do the tire size numbers tell you about the size of the tire. 22.3 is the rim size in inches and 75 is the aspect of the tire.

What wheel position on an 18 wheel is underinflated? The steering wheel tires.

Is there a maximum air pressure for each tire size?
No, however, there is a maximum load at certain pressures.

When tires are in a dual position which will wear faster? The underinflated one.

Does Tread depth of a tire affect Fuel economy of the vehicle? Yes – lower thread better gas mileage.

What should he maximum difference in circumference in 2 tires mated in a dual position. 1⁄4 or roughly 4/32 tread depth.

Check each tire every day that you are driving the vehicle. It is your best protection.

Steel braided hoses are the best if you choose to use hoses and valves.

Top tire is us are Michelin Good Year and Bridgestone.

Tire components, 1 ply blocking layer, 1st working layer, 2nd working layer protective layer, shoulder cushion and belt cushion.

The high performance items to consider are the noise reduction and friction when it is wet.

Touring tire is the tire to consider for quiet ride. And longevity. How to determine the age of a tire. Ex: DOT A3 4F 1W6 4108 DOT Department of Transportation
A3 Manufacturer Plant Code (where made)

4F Government size and ply code (size and ply rating of the tire) 1W6 Manufacturer Construction code

4108 Tire Build Date
first two digits are the week tire is made and last two are the year..

Identifying Load and Correct Air pressure Targets.

Where to find RV scales .
All commercial truck stop. Air tires up to maximum load

90% of tire failures stem from improper inflation.

The tread wears about 9-16 percent faster for every 10 percent a tire is below its fleet specified pressure.

Increased deformation = increased fuel consumption = increased stress.

Tailor air pressure to the size of your load.

To save fuel.
Reduce speed
Keep windows rolled up Turn air conditioning off.

Proper cleaning of RV Tires;
Clean with soft brush and a mild soap.

Park on wood but make sure the board is long and wide enough.

Match air pressure to the tires and the load you are going to carry.
