Load Range C, D, E, and F are common among off-road tires. The basic way to read this is to remember that load ratings increase as the letters in the alphabet go on.

Some manufacturers will install a speed governor if a vehicle is ordered with tires rated below the vehicle’s maximum speed. In this case it is possible to calculate the appropriate speed rating with a formula. The DOT code is part of the tire identification number, it is the final four digits.
The actual diameter of a specific tire size can only be found in the TRA Yearbook or the manufacturer’s data books. Note that the tire’s cross-section and diameter are always specified when measured on a rim of a specified width; different widths will yield different tire dimensions. Tires with a speed rating higher than 300 km/h are indicated by a Y in parentheses. The load rating is often included within the parentheses, e.g. .
Original tires, but look very good except tread wear bad on front, by appearNce from running with too low air psi. Eerie for me as just several days ago I wondered weather I should replace only my front tire as back looked like 70% tread ?

RMA stated that requiring existing plants to convert to 13-symbol TINs imposed substantial burdens on manufacturers not using all of the currently optional portions of the TIN. RMA also stated that the agency was incorrect to assume that the average life of a mold is five years. In January 1971, the agency established a requirement in 49 CFR part 574 for a tire identification number that must be labeled on one sidewall of each tire that is newly manufactured or retreaded. The purpose of the TIN is to facilitate notification of purchasers of defective or noncompliant tires. Furthermore, the information contained in the TIN may be used by consumers to obtain information about the tire such as the actual manufacturer of the tire and the date of manufacture. Part 574 also provides for the registration of tires, including the collection of the TIN and the contact information of purchasers of tires, to enable manufacturers to notify tire owners of recalls.
Power steering and diesel engines were now available. The Workmaster tractors had an all red hood and grille. “Powermaster” tractors had gray on the sides of the hood. What all that means is the casting date code on any part must be at least 30 days prior to the part being machined. In the case of an engine block, final assembly and testing had to take place before the hand-stamped serial number was added. Tractor assembly would probably have been several days or longer after the engine passed QC and was stamped with a serial number.
