Michelin Pilot Alpin PA4 N-Spec 

Tire has performed well in all conditions, wet/dry/snow. The noise level has been very good for a snow tire. It's quieter then the OEM Conti's. Notice very little wear after 5,000 miles of first winter. Will definitely buy again. Audi doesn't recommend anything other than their AO spec tires, but these N Spec tires are perfect for the A8L.

Has been light winter with little snow this year in my area (NE US), but what I did drive in mainly slush was good. Feeling is very confident in dry and wet (rainy) roads. Cornering has been good as well as higher speeds on highway. Smooth ride and quieter that my summers. Wear has been light even in warmer temp (60 F was hottest day). Should be able to get few seasons from them.

I bought these because they were only ones I could get that fit (I was looking for all weather.). My summer tires were/are like driving slippery at any temperature below 50F. At 40F, like glass or hard plastic. Since purchase, I have driven in wet weather at 30 to 40F and they provide excellent traction. No more slipping on hard acceleration. No hydroplaning at highway speeds.They feel fine at temperatures up to 80F and do not get hot. They are much quieter than the summer tires and provide a more comfortable ride.They are not as responsive as the summer tires but provide much better traction in the cold(anything 50F are cooler). I have 2500 miles and they show no wear. I will switch back to summer tires but keep these for next winter also. I would buy again. I am impressed.

Michelin just released these tires in two different varieties. These are the Porsche developed 'N-spec' directional version. There is also the asymmetrical tread pattern suggested for AMG Mercs and other high end cars.

Although I haven't had a chance to test them in harsh winter conditions, I have had them out in some rain, freezing rain, and sub-zero temperatures. They grip like crazy and have very minimal tire noise. I had a set of Bridgestone LM-25v's on the car last winter and I was ready to throw them off a cliff.

In dry conditions I can still drive like a 450hp gazelle and not have to worry about a close encounter with death.

Highly recommended if you have the cash.

We live in Denver but spend many weekends up in the mountains, especially in the winter. These tires have performed well in both light snow and heavy snow with 3-5 inches on roadway. I have not had the opportunity to drive in icy conditions. They are mounted on 19" BBS wheels and road noise is light. Dry conditions are handled well. I would buy again.

- Rear tires (265/19/40) were "special price" but were 3.5 years old (manf. mid 2012, pur. 10/2015). (the manuf date is last 4 digits of the DOT string of numbers).
- Front tires were "normal price" and 1 year old (manf. mid 2014, pur. 10/2015).
- Labeled as "Performance Winter" which means it is a compromise between "Snow" and "Performance." It is V rated. Porsche dealer says hi-speed tires can't be patched/repaired; have to be replaced so they sell a replacement plan which assumes you replace 2 tire/wheel combo ($about $1,800 @ dealer price) over 5 years.
- As a combo tire, you get "Good" snow traction, "Good Ice Braking", "Good Hydroplaning", "Good Handling", "Good Ride Comfort." The minus side is "Fair Wet Braking" and "Fair Dry Braking." (Therefore, adjust your braking habit on cleared roads.)
Overall, you get enhanced snow performance, but compromised dry braking and adequate dry weather performance.
- These are unidirectional tires, meaning, pay attention to the rotation marking (arrow pointed forward).

I've used Pilot Alpin snow tires for about 12-15 yrs. Have always felt safe and confident with them. This is the first PA4 tires and they were probably better than the last PA3 (?) models. Had to drive in the mountains for about 180 miles in passes etc. Nothing stopped these, and easily could pass on inclines and they stayed planted even in deep new snow. Great on slush and even icy condition. Will definitely buy these again. They are even more quiet than my PSS, though many say those make a lot of noise. They handle great in the dry for a snow tire, though no where near the PSS summer tires.

I was very surprised with the Michelin Aplin's. Great performance in the snow and wet conditions, I run them right into spring before a change over to my summer set up. I also have a set of the Aplins for my 328i rear wheel drive. I live in the mountains of Pennsylvania and we usually get a fair amount of snow and temperatures are near freezing 4-5 months a year. Uneven and pothole ridden roads are everywhere, so wear and tear were also a concern for me. I used to run Pirelli's in the winter but they go so quick. I was able to get 12000 miles (11600 actual, I keep track) out of these, and they were right at 7/16th thread at time of disposal (bare minimum in PA). I don't think there's anything bad I could say about these tires. You won't regret getting a set.

Excellent tire tread wear is perfect with regular rotations

Tires exceeded expectations! In dry cold, below freezing, sidewall is a bit softer than PS4Ss, but she still handles just about as well. Turn in dry and cold not nearly as responsive as PS4Ss, though. Drove home from tire shop with about 10" of snow, other than snow getting stuck in the radiator holes up front, tires plowed right through w/zero issues, I wouldn't recommend driving boxster or cayman in any more than 5"-6" of snow. Driving on packed 3"-4" of snow, w/traction control OFF, cars is very manageable drifting and controlled slides. Very little slippage when giving about 1/3 throttle and accelerating up to 60mph, breaking is also excellent on packed snow. Wet cold conditions also excellent. Have driven 5000 miles thus far and tread wear is almost nil..........well worth the $$$!
