I liked the tire sizes Traxion offered (tall and narrow pizza cutters) and they would fit a stock 5.5" Tracker rim size. A 30" tire, 7" wide, mounted on my factory 5.5" rims.... would completely clear my inner frame when turning lock to lock. I don't think even Interco offers these sizes in their tire lines. I have never rolled one of my Suzuki trucks on bias ply tires and was curious just how "bad" the ride is with 28-30 pounds of pressure in them with these old school "mud grip" designed tires.
I generally try to avoid interstate driving. I've heard from many about the off-road benefits of the Interco tires but they were designed as primarily an off road use tire, their large heavy lugs wear down very quickly on hard ball, and traction on wet roads wasn't a consideration for many of their bias designs, plus the extra road noise from their hyper-aggressive tread design. I was looking for something in between AT type radials and Intercos, I guess.
I'd probably mount them on a spare set of rims so I wouldn't be stuck rolling just the STs all year long. Current AT and MT radials are limited in available size and widths and I don't see that changing in the future, just getting worst. Bias tires are better suited to "clean" themselves of mud and debris. These STs tires were designed for on and off-road use although I understand I couldn't expect Michelin LTX traction on the hard ball. Dual use tires are a compromise. It just sucks loosing traction in 1/2" of mud. Just looking at what is available and exploring the different options.
