Yokohama utilizes the latest in tire technology, including the use of Orange Oil, on the AVID Ascend touring
all-season tire. Designed for a variety of coupes, sedans, minivans and crossovers, the Ascend is engineered to
provide all-season traction, a longer treadlife, and a lower rolling resistance for better fuel mileage.
Orange oil technology is a new technology that uses oil extracted from orange peels. The basic principle behind
the technology is that it improves the bond between the different types of rubber in the tire to enhance treadlife,
traction and fuel efficiency. We have found many drivers stating that this new technology has indeed made this an
excellent overall tire.
Dry road surface traction and cornering are increased through the larger tread blocks on the outside shoulders
and the Interlocking Tapered Center Rib. They combine to add responsive steering and greater stability throughout
the speed range. Tread Block Bridges not only add to the tire's stability, but they also help in reducing tread
noise. The multi-pitch tread design further eliminates noise and makes for a very quiet ride.
On wet or snow covered surfaces, the tire's four deep cross & circumferential grooves along with adaptive
3-D siping around the tread enhance traction and increase overall performance. The sipes biting edges provide more
grip on snow and ice, while the circumferential grooves evacuate more water from under the tread and reduce the
risk of hydroplaning. The result is more confidence driving in any type of rough weather.
Inside the tire you will find two steel belts that are spirally wrapped with nylon for added reinforcement and
improved durability. Yokohama includes up to an 85,000 mile tread guarantee depending on the tire's speed
Dry, wet and snow traction and handling are excellent
One of the quietest touring tires you'll find anywhere
Lower rolling resistance increases fuel mileage
Outstanding treadlife and an 85,000 mile warranty
Softer sidewall on T speed rated models
Yokohama produces some very good tires throughout their lineup, but this new Ascend is one of their best yet. It
provides the performance that the company advertises. Traction and handling on dry, wet or snow covered roads is
excellent. The tire (especially in H & V speed rated sizes) provides responsive feedback that leaves you
feeling in complete control.
Outside tire noise is virtually non-existent on this model. The ride is smooth, and cornering performance is
very good for a touring tire. We did find other drivers mentioning the T speed rated tires have a softer sidewall,
so if you like a little more spirited driving performance you may want to consider getting the stiffer H and V
speed rated tires. The tread features a lower rolling resistance and many drivers have commented on improvements in
fuel mileage. Finally, the treadlife is long on this tire, and Yokohama provides a first-class warranty. Overall,
an outstanding choice in touring all-season tires.
The Ascend comes with a 5-year or 85,000 mile tread warranty on T speed rated models, 5-years or 75,000 miles on
H speed rated tires, 5-years or 65,000 miles on V speed rated tires. All models have a tire uniformity guarantee
for the first 2/32 inch of wear.
Materials and workmanship are warranted for 5-years and include free tire replacement during the first year or
first 2/32 inch of wear. The amount is prorated for the remaining time period or down to the final 2/32 inch of
Yokohama also gives a 30-day test drive in which you can refund or exchange the tires if you are not completely
