Ultra High Performance All-Season tires are for driving enthusiasts who want a combination of a performance appearance, responsive handling and Z-speed rated (or higher) durability along with all-season traction, including in light snow. Ultra High Performance All-Season tires branded with the M+S symbol are often used as Original Equipment (O.E.) on sports cars, performance coupes and high performance sedans.
O.E. Ultra High Performance All-Season tires are typically purchased as direct replacements for worn-out pairs/sets of the vehicle’s original tires. They can also be used for other vehicle applications in complete sets of four or axle pairs if available in an appropriate size, load range and speed rating to match the existing O.E. tires’ performance category and specifications.

This tire came with my new 2011 G37. It’s a mix of aggressive miles and easy miles – I consider myself average. From the best to the worst (compared with other tires)1. Quiet and smooth, above average OEM2. Good wet handling and reasonable hydroplaning (still water). Did not let me down on snow – even only once, with hardened icy snow, I easily drive up at 10-15mph at a community S ramp of 13.5 degree (feel I am in a tractor, just slow and bumpy, no slip, slide, etc).3. Tread wear is OK for 250 AA spec. However, after the tread worn down to 7/32, the performance started to degrade. Check tread using gauge – even wear (regular rotation and well balanced).4. With 250AA thread wear (and softness), the dry handling is far under expectation, cornering is poor (even after upgraded swaybar and added 15mm wheel spacer).When they get to their life, I will buy something else, considering Potenza RE AS (better dry handling) or Continental EWS (lighter and good on Nissan cars)
My used 09 g37x had a brand new set of these tires on it when I purchased it in 2012. Traction and turning has been very good and for my driving style treadlife seems well also. Starting to get a little bit of noise on the interstate unless I’m on one of the “newly paved” highways, but the noise isn’t as bad as cheaper tires have. Light snow and ice they did good but the car is AWD so not sure how much credit the tires deserve. They probably have about 10,000 miles left on them. Currently stuck on whether or not they’re worth $1,000 dollars for another set.
The tire is finally wearing down to where I don’t want to use it in winter conditions after 55,000 miles. Lasted a lot longer than I expected from a tire. The tire is still pretty decent in wet conditions. Was a good snow tire on my AWD in NY (Long Island) winter conditions. The only negative about these tires are their extremely high replacement cost!
OE equipment on my 2011 G37X. Not happy about the noise/harshness of the ride. Provides good cornering stability, good dry traction. We traction is ok, but not great. I’ve definitely owned worse. Have to admit that I was mightily impressed with this car in the snow. My first snow outing was a blizzard….car handled very, very well. How much of that was down to all wheel drive and traction control, I am not sure, but I have been quite satisfied in the snow.
These tires are oem on my 2010 Infiniti G37xs(all-wheel drive, sport edition with 18″ wheels). I repurchased them when factory set wore down . If I had to pick the worst quality of these tires ,I guess it would be tread wear, but that really isn’t bad when you consider these are not high mileage tires. These tires handle great, stick in a corner like glue,especially once a little break-in miles occur. Wet is excellent als. In the snow I found them to be very confidence inspiring.I drive like a bat out-a ——— on curvy back roads,and don’t let bad weather slow me down much on highway pavement, I don’t mean to say I’m reckless ,but I do put car and tire to the test and I have been very impressed by these dunlop tires on my Infiniti G37xs in 225/50r 18 with a94v speed rating. They are not cheap ,but if you want to play sometimes you got to pay !
Excellent tire for an Ultra Performance All Season tire.I was down to 4/32nd’s at 20,000 miles.. Loved them just to fast wear.Quite and Grippy right down to the ware bar.. MAX tire life my guess 25K/27K miles.You get what you pay for.. this is slightly to rich for a leased car..
