Dunlop SP31 A/S Tire Review & Rating

The SP31 A/S from Dunlop is used for the most part as original equipment on today’s new fuel efficient vehicles like the Honda Insight, Fit, and Civic Hybrid among others. Created to provide all-season traction, a lower rolling resistance, and a comfortable ride, the SP31 uses the latest tire technology to enhance performance.

The all-season tread compound is M+S rated for use in all types of weather and road conditions, including snow. More on its winter traction below. An asymmetric tread pattern features a lower rolling resistance to increase traction, while also improving overall fuel efficiency.

SP31 AS from Dunlop Tires

Circumferential grooves around the tread expel water and reduce the risk of hydroplaning in wet weather. Dunlop uses its multi-pitch technology to lower outside road noise and increase the ride quality. It works pretty well according to many drivers.

Inside the tire you will find a steel belted construction that adds strength and durability to the tire, as well as promoting more even tread wear. Dunlop provides a limited warranty on this model, and the SP31 AS is available in S and H-speed rated models.

Pros

  • Dry pavement traction and handling are very good   
  • Comfortable ride   
  • Lower road noise   

Cons

  • Treadlife has been a major issue to many drivers   
  • Snow and ice performance   

Overall Thoughts

We’ll just get to it real quick… the SP31 is simply not a tire we can recommend. While its performance on dry and wet pavement is adequate, and the ride is fairly comfortable, the negatives this tire displays far outweigh the positives.

Treadlife has been a major issue for drivers according to countless driver reviews on this tire, with many reporting they have gotten less than 25,000 miles out of the tread. Beyond that, winter performance on this model needs big improvements. Trying to gain traction on any amounts of ice is useless. Further, the lack of a tread mileage warranty is also an issue.

Overall, Dunlop builds some very good quality tires that we rank highly, but for whatever reason, this model is nowhere near up to their standards, or anyone else’s for that matter.

These tires provided spectacular gas mileage on my Honda Insight hybrid. However, they were a little on the loud side for road noise and provided a ride that was a bit on the stiff side. At just over 40,000 miles, one of the tires started to come apart. It was delaminating.

I spoke to a friend who is a true tire expert. He recommended the Hankook Optimo 426. The Optimos are not as good on fuel efficiency, but they provide a much softer ride and are expected to last 60,000 miles.
