My very reliable Goodyear Silent Armors, have long been out of production.
These tyres proved difficult to puncture and had strong sidewalls in rough terrain. With some tread life remaining, they were pushing 7 years plus and needed replacement.
I decided to stick with the original size 225/75R15 (while products still exist) and found two tyres that I could choose from: Bridgestone D697 Dueler or the Goodyear Wrangler Silenttrac AT.
I stayed with GY. It is too early to give a review, but the first thing that I noticed was the drop in road noise, and improved ride comfort. It is like having an extra layer of suspension. Performance on road and in the wet is at another level. The sidewalls are made of the same materials as the outgoing Silent Armors. The gaps between the tread blocks are deep even though the tyre at first glance (outwardly) appears like a highway tyre.
It will be interesting to see how it travels off road.
