A practical note on reading an OTR tire datasheet before you order.
Three lines on a datasheet decide whether a 4-tonne tire lasts 5,000 or 9,000 hours.
Speed, load and ambient temperature decide how hot a tire runs.
Construction decides heat, footprint and how the tire fails.
The number on the TRA code sets how deep the rock tread is.
Premium and value patterns can share a size and still differ by thousands of hours.
