Tires

I did a little research and found that the basic construction, including the innerliner, of our tubeless and tube type tires are basically the same. This means that there is no reason that a tube type tire couldn't be run tubeless as long as it is mounted on a proper rim or wheel and the rim or wheel properly seals the air in the tire.

The revolutions per mile are published for specific tires not just tires. In other words, the RPM for an 11R22.5 Goodyear G395 LHS tire are not the same as a 11R22.5 G372A LHD. The drive tire (G372A) has a deeper original tread so, when new, its RPM's are less than a shallower tread new steer tire (like a G395).

Of the two steer tires, if alignment is correct and all steering system components are within specs, the left front tire will tend to wear quicker than the right front tire. There are a couple of theories about this but the one that make the most sense...the left steer tire is connected directly to the steering box but the right steer tires is connected via the drag link. Even with just a little "free play" in the system, this means that the left side tire is doing a little more work as it reacts instantly to steering inputs.

The first priorty is to make sure that tires mounted as duals have diameters within 1/4 inch. When diameters are greater than 1/4 inch, the larger of the two tires begins to take on too much of the load creating a series of concerns. Matching of the tread pattern (lug to lug, rib to rib) around a vehicle is desireable but not critical (especially on a trailer). Finally, matching the tire brands is good since the physical properties of the tires would be consistant but, again, this is not critical. If you look at the tires on most fleets, there is a mix and match of tire brands around the vehicles, especially the trailers.

U.S. DOT Tire Identification Number is on one side of every DOT approved tire. This begins with the letters "DOT" and indicates that the tire meets all federal standards. The next two numbers or letters are the plant code where it was manufactured, and the last four numbers represent the week and year the tire was built. For example, the numbers 3106 means the 31st week of 2006. The other numbers are marketing codes used at the manufacturer's discretion. This information is used to contact consumers if a tire defect requires a recall.
