I have been running Firestone Transforce HT 245/75R16 E/10PRs on my 2005 Tacoma since the factory skins started going flat at 25,000 miles. I am on the fourth set (225K+ on the odometer) and have had only one flat--a rock cut after a long, rough outing on a really gnarly road. You have to run them a little hard (I keep mine at 40 PSI, minimum), but they do hold up well on unpaved roads and rocky two-tracks. I get 55-60K miles out of a set and I don't run the tread down to the recommended replacement depth.
