I was looking at the Cooper STT last night, the SEMA pictures spawned my interest. If I would have had the chance to look at those when I was purchasing I would have considered them. I wanted 315 MTRs and couldn't get them when I was purchasing(6 month backorder). So I went with trusty BFG ATs. I'm happy with them but I'm now longing for something more agressive as gas prices have shifted my use of the 80 to primarily off road. I won't mail order tires because I need the road hazard and mounting and balancing locally.
Noah are you looking at going to 16" rims? I like the 16s on my 94, but I liked having more cheap tire sources for the 15" rims of my 91.
I've said this in other threads, but you can't BEAT the deal on Dunlop MTs. Very aggressive tread, wear a long time, and they're like $125 for 35s and $150 for 315s.
People berate me also for this, but I have had great luck with the BigO XT. Knock on wood, but I've never had a tear or flat on them and they've work really really well and do a respectable job off-road. Anyway, they've got the lifetime warranty, etc.
