I just bought these for a 2007 A6. They do ride nice. I bought them mainly because the car came with continentals originally and had no complaints. Does this eco technology really save fuel? I bought them mainly based on price/tread wear, the procontacts which came on the car were much more. They are stamped made in Mexico, not sure where the original tires were made though.

All these lower rolling resistance are minor.
we are talking about about 1% per tire not matter which brand you go with.

the difference only matters if your alignment is great, all 4 tires are of same kind, and all tires are properly inflated.

Something to keep in mind is that lower rolling resistance also creates less friction in breaking . The tires wont make you get in accident but its something to keep in mind when your paying a premium for it.


The improvement is same as underflated tires and properly flated tires, wont save you dollars each time to pump but over theoretical 10's of thousands of miles it adds up.

I just got the purecontact line on my accord and I love them, nice rim protector, great traction, and 700 A A rating

to be honest I think I get worse mileage than my previous Goodyear eagle gt tires. they had super stiff sidewalls, but definitely worth the dip for increase in comfort

The "LRR" is a relative term, not an absolute term.

Yes, LRR will save fuel IF you are replacing tires with identical treadwear and traction ratings (but that hardly ever happens). What is more typical is folks replacing OE tires - which were designed with good Rolling Resistance, (and that results in poor wear and/or traction) - with LRR tires with high treadwear ratings and they get a loss in fuel economy - but it's better than if they used non-LRR tires.
