Time for new E rated tires. Any suggestions?

I too had been a fan of the Michelin's but not so much since they appear to have started having problems with their newer tires. The truck currently has Firestones and they have been working out well. I really don't know about mileage yet.

Also, I use Tire Rack as a data base a lot but I find that they do not have all of the sizes of tire available on their spec lists.

The Nitto Duras look good.
