Discoverer HT3 LT275/65R18

Cooper Discoverer HT3 Tires are premium light truck tires with a commercial highway rib to give you the best of all season performance. Avoid abnormal treadwear with the special design of the HT3 and enjoy enhanced tire life with your HT3 Tires. A continuous shoulder rib gives the tire excellent resistance to uneven or irregular wear as well as making things quieter in the cab. A silica tread compound enhances the Discoverer HT3 traction in wet conditions. Additionally, there is 3D Micro-Gauge siping which is an interlocking geometric pattern that increases overall tire stability. This results in better vehicle handling and reliable all-season performance. Lateral slots have been increased for this model which helps with traction in wet weather and snowy conditions.

Features & Benefits

  • Abnormal treadwear resistant due to specially designed 3D Micro-Gauge siping
  • Good all-season traction and handling due to silica tread compound
  • Lateral slots to increase traction and repel slush and water

Dry Wet Snow Comfort Noise Treadwear
On Cooper Discoverer HT3 Tires
I haven't driven the truck too much, but when I have, its rides nice and feels secure on the road whether dry or wet. I haven't driven it in the snow yet, hence a 4 star.

Put these on my 2003 Toyota truck because I got them at a steal! And they are worth every penny I paid for them. These tires handle nicely in the rain, as well as in dry conditions.
