Bridgestone Dueler A/T 694

I drive a double cab raised body pickup and fitted new Bridgestone Duelers because the previous range had a good reputation for off road use. I drive two thirds tar road and one third gravel road every day. The tires lasted 50,000 km's till smooth with the indicators now gone and dangerous to use. I had two punctures in this time, one being a nail penetrating on the shoulder and one fencing rod that went straight through the middle of the tread pattern. I was impressed with the ride comfort and tractability of the tire in the beginning, but it became a harder ride and often losing traction as the tire became more worn. I was disappointed with the mileage attained with the tires, as previous range Duelers were known to last better than other brands with a lot of gravel use. I will now be fitting Goodyear Wrangler A/T Adventure tires of the same size, to see if they will fare better.
