I did a fair amount of research before I bought tires for my 1/2 ton, and the Bridgestone Dueler Revo had by far the best reviews. I’ve had them since last June and I really like them. They’re a great compromise between highway and offroad: quiet, good mileage, but gets me up an icy ramp. I looked around quite a bit on price, and I was as surprised as anyone when I got the best deal at Tires Plus. It cost about $50 more (incl. tax) than ordering the tires over the internet and having them installed by a friend of a friend (at a discount). I figured $50 was worth it to save me the hassle/time involved in getting the tires/truck to the shop, and owing a favor back for the install. I also checked on other shops for installation, and ordering over the internet and having someone install at retail would have actually cost me more than going to Tires Plus.
My truck has 265/70/R17 size tires, and I’m not sure what your 3/4 ton needs. In any case, look at the Dueler Revo. Whatever you do get decent tires, Steve. I don’t want to have to pull you up the 494 ramp this winter!!
