Tire Test Results from Tirerack.com
 

I thought it may be helpful to post these tire tests in one place so consumers can easily find them and see how different tires perform so they can make a purchase with a bit more confidence.

I'll start with a few newer tests and add more as they become available. Please feel free to suggest other tests that I miss and I'll add them to this first post. Thanks!

Are Front-Wheel Drive and All-Season Tires Enough for Winter Driving?
Are Front-Wheel Drive and All-Season Tires Enough for Winter Driving?

I actually have the Michelin MXM4 tires installed now. It doesn't seem like the ones they reviewed are the "GreenX" LRR version that I have. So far, I like them, but I haven't been able to test them extensively just yet. I have ~ 1,000 miles on them at this point, but that is mostly city driving on relatively warm, dry pavement.

I've seen about a 10% improvement in fuel economy, but that is in comparison to a high-performance summer tire. Of course, that mileage might improve once the tires finish breaking in. The dry traction is, obviously, a downgrade, but they seem to handle well enough. Still, I know that I can induce a power slide on demand... maybe not a good thing. :eek:

I'll have to do a follow up when I have more information. Winter is around the corner, so I'm sure to see some wet (and possibly snowy) conditions soon. I also have a few long highway trips to make, plus my freeway driving should be increasing in frequency.

The size they tested is greenx rated. :) What size are you running? I have them in a 215/45/17 so the mpg is not great but they are very quiet, ride great and handle very well for a touring tire. I have to push them pretty hard before I hear any complaints and I have a few suspension upgrades so this car is no tuna boat. lol

Keep us posted on your experience with them. I don't know anyone else that has them to compare notes with.

I have them in 235/40R18. Yeah, don't get me wrong, they handle competently enough... it was just a major downgrade in dry traction. But that is to be expected going from a high performance summer tire to an all season.

It doesn't help that you have a performance car that actually requires the extra traction. In my car there is no such thing as powering out of a sharp corner. lol

Yeah, that's why I'm not overly critical of the traction. You'd have to be intentionally reckless for something to happen, and that's why I'm still giving these tires a big :thumbup: so far.
