Best LRR tire available now?
Most of the lists I have seen are a few years out of date now.
From Nokian's website this year. Our tire with the least rolling resistance is the Hakkapeliitta R, a true winter tire that out rolls many competitors' all season "fuel efficient" tires. ... Ultra-Low Rolling Resistance The new Hakkapeliitta R has the lowest rolling resistance of any tire in Nokian Tyres product line. ... That is really suprising to me, because I expected a summer tire with smooth tread to be the best. But this is also interesting. Quote:
So I guess the best LRR tire is a worn LRR tire. And you can save a lot of money buying them. Just don't use them in snow or heavy rain. |
At no point does Nokian say that their tires are the best over all, they say
Quote:
They also claim that they are even better then many "fuel saving" all season tires... very vague! as they never define fuel saving tire. They never out right say that their tires are the best, nor do they quantify their claims in a way that you can then compare, they don't even pick out a "fuel saving tire" that their tires are better then. |
Michelin Harmony seems to be a good choice for LRR tires.

In Europe, the Michelin Energy Saver and Goodyear Efficientgrip were tested to have the lowest rolling resistance of a group of test tyres.
Surprisingly, the Michelin Alpin A4 winter tyres roll just about as well as the Energy Saver - I get the same coasting distances out on the road. |

Unfortunately, Michelin Energy Saver A/S is only available for 15" and bigger wheels.
Also unfortunately, Tire Rack doesn't sell or compare Nokian tires. Of the best LRR tires, only Bridgestone Ecopia EP100 is available in 175/65R14. Bridgestone B381, which won the 2003 comparison, and Nokian eNTYRE are available in 185/65R14. So I may be using one of those on my Geo. |
Though Nokian's Hakkapeliitta R snow tires are Nokian's lowest rolling resistance, they are decidedly not the lowest RR tires on the market.
I believe that crown still belongs to the OE tire on the first-gen Insight, the Potenza RE92 in P165/65R14. Other sizes of the same tire are a different formulation. I have yet to hear any substantive reports of an Insight owner getting better mileage or better coastdown tests with any other tire, so it's still the champion. Too bad it's only available in one size, and it's unavailable in Europe. |
MICHELIN LTX A/S, of course. (Oh, you don't drive a 7,000-lb truck?). :D

165/65R14 would be a good fit for my Geo, but it's only 3% overdrive. I want between 5% and 10% overdrive. 175/65R14 is what I am planning, which is the same as the early Prius. 175/65R15 is what the new Insight uses, and that would be 10% overdrive for the Geo. Larger wheels have better LRR, but they also weigh more. |
