The Dimax AS-9 is Radar's Grand Touring All-Season tire developed for the drivers of sport coupes, sedans, crossovers, and sport utility vehicles (SUVs). The Dimax AS-9 offers a fusion of driving pleasure, performance, and safety. The Dimax AS-9 is built to operate all year long in various weather conditions, including in light snow.

The Dimax AS-9 uses a silica-based tread compound formulated to increase grip on wet and dry roads. This compound is molded into a symmetric tread design that promotes even wear, improves ride comfort and reduces noise levels. Robust shoulders enhance lateral grip on dry roads, while the rigid center rib provides solid handling and precise control. Four circumferential channels flow water from between the tire's contact patch and the road to enhance hydroplaning resistance and wet traction. Dense lateral siping increases the biting edges needed to enhance traction in light snow.

Internal construction of the Dimax AS-9 consists of a 2-ply polyester casing engineered to provide durability along with a comfortable, controlled ride. Twin, robust steel belts and a nylon reinforcement ply help support the tread and casing and improve handling and high-speed stability.

This is my second set and I refused to consider anything else. They are loud when compared with others, but I find they provide excellent traction in rain and snow, and lasted me about 60,000 miles with regular rotation

...Good tire, great traction and response on dry and wet roads...

About a thousand miles so far. Good tire, great traction and response on dry and wet roads. Low noise, but can be heard if you shut off the radio. Worth the lower price compared to American named companies.

...Handling is great, no problem on light snow, never felt like hydroplaning was a risk, lateral cornering on wet on spirited driving has made the rear slip slightly but recovers quickly and never felt like actually losing control...

These tires have been on my 4Runner for over 7 years and over 60k miles, they seem to last forever. Comfort is great, noise is low, handling is great, no problem on light snow, never felt like hydroplaning was a risk, lateral cornering on wet on spirited driving has made the rear slip slightly but recovers quickly and never felt like actually losing control. For the price these tires are fantastic. I bought them because I wanted to save money and at the time felt like taking a gamble. But now that the time to replace them is approaching I am seriously considering getting another set. They are cheap compared to others, but they are definitely not low quality or low performing by any means.

The Encounter HT2 delivers strong winter performance with most snow/deep snow scores 8-10. Ice traction holds up well (mostly 7-8), though occasional lower scores suggest variability in extreme ice conditions.

...traction on cold icy conditions has been extremely gripping.

These tires are a perfect choice for the average commuter in an SUV type Vehical . My wife has been extremely happy, all seasons of driving have given a great testing for these tires. They have never left her stranded, and they wear beautifully. Even without studs, traction on cold icy conditions has been extremely gripping.

Surprisingly competent in snow (on an AWD CRV), but no surprise that snow tires are better in heavy snow. Good, quiet ride. They don’t squeal when you push hard on dry road. Will buy these again, and will try a set on my Sentra when it’s time for replacement.

...This newer version tire exhibits a considerable performance improvement in both wet and dry conditions... All wet or dry, I get crisper response to steering input, more stable under cornering and controllable under braking...

I bought this set of tires to replace the earlier version of the same tire that served me well for about 50,000 miles. The previous set of tires still had legal tread depth but were getting pretty slick feeling in wet weather. This newer version tire is a exhibits a considerable performance improvement in both wet and dry conditions. That is quite a trick as I would have guessed the shallower tread depth of a worn tire would provide better dry performance. All wet or dry, I get crisper response to steering input, more stable under cornering and controllable under braking. Tread wear is not a huge issue for me if a tire works well, but these look like they will go a long way at this time.

...Comfort is great, mileage is off the chart...

In stock, received in just a few days, plus they were on sale. Water on road, they cut right thru with no hydroplaning. Light snow, my vehicle has electronic AWD. You kick it in and the front wheels dig in, the front rises, and you take off. Comfort is great, mileage is off the chart. These replaced the same tire only an earlier version. Old ones had 87,500 miles and not to wear bars, but they were 6 years old so I replaced them. For highway/city driving this tire is the best.

These tires are great. I first bought a set for my Durango. I was so impressed by this brand I bought a set for my Passat.

These tires ride nice and the road noise is mostly quiet and definitely beats some of the other tire brands I’ve had on my other vehicles.

Definitely worth buying. You can’t beat this price for what you get. I’ll most definitely buy this tire again when I need my next set of tires.

This is the second set of this tire I have used, although this appears to be a slightly different designation "HT2". I can see no obvious differences between the two sets. I got 60,000 miles on the first set and still did not wear down to the warning bars. I highly value wet weather performance and was satisfied with the performance of the first set, so I did not seriously research an alternate selection. I appreciate the very recent date codes on the tires as I do not put as many miles on my truck as I used to, and I do not like to use tires older than 5 years for expressway speeds with sometimes heavy loads and trailer towing.
