Replaced the starter on the truck and noticed the dryrot in the tread. These 20-year-old or so Bridgestone dueller MTs need a change. Right now the size is 32x11.5x15 on some old school American racing rims. The suspension is stock and super flexy, so I'm thinking of downsizing to 31x10.5x15 on some tacoma steely 15s I have laying around. Whenever my 40 sees off-road, which is rare these days, it's almost always mud and a water crossing, but I spend most of the time cruising around the backroads naked with the windshield down. Snow and ice is not a concern. Any recommendations from those tire nerds that have recently been doing the same research? I'm kind of tired of running the retreads, as most shops can't balance them worth a damn. Thanks ahead of time for the ideas.
