1) According to Caterpillar Corp.:
* from 55-mph, to 80-mph, the rolling resistance coefficient will increase 7.4%.
2) According to Bridgestone/ Firestone:
* LRR tires suffer the highest increase in rolling resistance with increased speed, compared to non-LLR tires.
* Between 55-mph, and 75-mph, you lose 27% of a LLR's mpg benefit.
