LRR (low rolling resistance) tires - Green Seal report & list

For those considering replacing their tires with a LRR versions, this report is a good place to start for general info. It's getting long in the tooth (1993), but the basics still apply.
  • 1.5 to 4.5% of total gasoline use could be saved if all replacement tires in use had low rolling resistance
  • About 237 million replacement tires are sold in the U.S. each year – none has rolling resistance labeling
  • This report presents previously unpublished data on leading tires with low rolling resistance
Report (PDF): Green Seal's Choose Green Report: Low Rolling Resistance Tires

Excellent Report

This is a great report -- I used it to purchase my latest set of treads. I attribute a decent percentage increase to my over-inflated LRR's.

For more up-to-date info, Consumer Reports has rolling resistance data in their tire reviews. The problem is that it requires an online subscription to the site or the magazine. You may be able to check your local library and locate a hard-copy for reference -- but those are the only references that I've been able to find actual testing on this subject.

I saw the Consumer Reports report in late 2006. It rated rolling resistance the same way that it rates everything else, with the red dot / black dot system. There were no actual LRR numbers. At the top of the list in 2006 was the Michelin Energy MXV and just under that was the Michelin Harmony. I bought the Kumho A/S 795's for the Prius which ranked just below the Michelins, but were 1/2 to 1/4 of the price. The sidewall max is 35 PPSI but I have been running them at 50-55 PSI. 40k miles so far and easily another 40k in them.

Hopefully the 2007 report had actual LRR values in it. If so, I would go to the library to see it.

With California's July '08 implementation of LRR labeling & standards, I'd expect it's going to get easier for the public to get info & make judgements than it has been.

My car's tires are more likely to dry rot off the rims before I ever wear them out, so eventually I'll have to shop for replacements too :P

FYI that report is from 2003

The most comprehensive List I could find was (still old from 2005)

not to grave dig, but I'm going to shop for some Low rolling resistance tires and was wondering what the best choice is as of right now...

Maybe there's a newer chart out now?

Even if there is an up to date study, those tires mentioned are still awesome to look into. Just looked at the top of the line Bridgestone B381's and they are going for about 90 bucks a piece. Steep price, but they are the best on the original study.

I just bought 2 new Michelin Energy Saver Tuesday. The bad news is they were pumped at 23 lower than the minimal placard (33) so I pumped them up to 46 this morning

After a little search I found that :
Sommerreifen 195/65 R 15 V (2008) - Tabelle
Sorry, it's in German... Thanks to babelfish :
Code:
trocken             = dry
nass                = wet
geräusch            = noise
kraftstoffverbrauch = fuel consumption
verschleiss         = wear
I don't know how they did their tests. The french forum in which I found the link was saying that my tires have a very good note except for breaking on wet grounds, so they are "recommendable" and not "particularly recommendable".

Denis.
