While driving a few minutes ago, I thought of something that needed to be added to this thread:

When I deduced the numbers down and got the RRC for my Blacklion tires, they seemed pretty good since they had a value of 0.010. This is right on the line between LRR and normal tires.

Then I remembered - The tires were pumped up to 70 psi for the test!

So! That will throw the numbers off if tire pressure is lower than I tested. I typically run them around 60 psi, so that would mean the RRC is higher than my test. Maybe not now, since my tires have worn down some and "loosened up".

Hmm... makes me wonder what the RRC is if they are at placecard psi (35 psi).

Actually, I think I will test the RRC between placecard psi and hypermile psi eventually. It will be good to have numbers behind what we already know is a benefit.

All in all, the test concludes that I need LRRs... asap!
