LRR Tires, questions

2799 Views 7 Replies 4 Participants Last post by  Holicow
Yes, there are numerous threads discussing different tire sizes and models. I have even done my own experimenting, with mixed results to say the least. I have decent knowledge of tires in general.

My questions are: (finally)

What is a Low Rolling Resistance Tire? At what threshold of rolling resistance is a tire now deemed LRR?

Is there any source that shows the rolling resistance of current tires?

My understanding is that LRR is like low fat. In other words its not an absolute value of a particular rolling resistance but rather a reduction of something like 30% from the Non LRR tire. I have looked and have not been able3 to find absolute numbers. Have fun, Rick
I used some 145/80 Goodyear's for about 1000 miles. (I thought they would help considering the smaller patch in contact with the pavement). The taller tires helped the ride a bit and they didn't follow groved pavement as bad but they weren't as good as the bridgestones for mpg. Have fun, Rick
