Performance on the laboratory test wheel than the minimum required by law. Grades A and B represent higher levels of The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. Life, and excessive temperature can lead to sudden tire failure. Sustained high temperature can cause the material of the tire to degenerate and reduce tire Resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. The comparative grade letters, A, B, and C (A being the highest and C being the lowest) represent the tire's TEMPERATURE A, B, C The temperature grade is based on an indoor, high-speed test that meets government-specified requirements. WARNING: The traction grade assigned is based on braking (straight ahead) traction test and does not include cornering (turning) traction. The comparative tire grade letters, AA, A, B, and C (AA being the highest and C being the lowest) represent the tire's ability to stop the vehicle on wet pavement under the controlled test conditions. The traction grade is based on a straight-ahead wet braking traction test and does not include a cornering TRACTION AA, A, B, C The traction grade is based on wet skid tests of a tire on government-specified concrete and asphalt surfaces. The relative performance of tires depends upon the actual conditions of their use and may depart significantly from the norm due to variations inĭriving habits, service practices and differences in road characteristics. For example, a tire gradedġ50 would wear one and a half (1 1/2) times as well as a tire graded 100 under the controlled test conditions.

TREADWEAR The treadwear grade is a comparative grade assigned by the manufacturer based on the wear rate of a tire when tested under controlled conditions on a course that meets government-specified requirements. DOT QUALITY GRADES All passenger car tires must conform to Federal Safety Requirements in addition to these grades. Tire manufacturers and brand name owners are required to grade regularĪnd all-season tires in three categories: Treadwear, Traction, and Temperature. UTQG designates the comparative performance levels of a tire based upon government-specified tests. Specifically to your particular driving habits, conditions, etc., is a possibility. As a result, misinterpreting the comparative data as it relates However, the ratings are based upon test results achieved under very specific conditions. Looks like I’m getting rid of these sooner than I thought.Is intended to provide simple, comparative data for your use in making an informed buying decision. I guess this is what happens when a manufacturer decides to spend its money on looks instead usability. The truck is the “Off-road” model, put real AT tires on it and not this garbage. This is the first time in 4 Rams that they have come with anything other than BF Goodrich or Goodyear ATs. In my 06’ I had never had any trouble with that entrance in 2 wheel drive, it came with BF Goodrich AT tires and then I swapped them out to Toyo ATs.

Luckily the entrance is on a slight incline so I was able to back up and then drive in the grass to pull in. I put it into both 4 high and low and the tires refused to dig in. We have had a lot of rain lately so the dirt and grass were really slick and the dirt had a thin layer of mud on top of it. I was pulling into a buddy’s farm yesterday, the entrance is dirt and grass, and the truck almost got stuck. These tires are complete garbage, they need to get rid of the “AT” part because there is no “all terrain” about them. Until I bought my current 19’ 2500 truck I had never heard of the Transforce AT tire, and yesterday I found out why.
