I have a set of Sumitomo HTR T4's on my Baja, size 225/60/16 and they are awesome. They are rated at 75,000mi tread warranty. They wear like iron and grip really well for a "T" rated tire. I had no problems in the snow, when they were new, and never hydroplane.
They are now at about 6/32" all the way around and wet grip isnt quite what it used to be but thats expected. I do drive them hard (drifting on wet roads and hard cornering in the dry) so I dont expect them to last 75,000 miles
They only negative is they are wearing a bit choppy so they're a bit loud but then again my Baja has modified intake and exhaust so its loud no matter what =)
The Touring LS-T is the same tire as the HTR T4 but had a harder tread compound and an 85,000 mile treadwear warranty so it wont grip as well on dry roads. Tread pattern is the same.
