I may have considered the ribs but in Canada I'd be looking at 400.00 installed per tire. Very tough to justify the cost at that point considering I'm looking at new wheels as well. There are a couple of LTs that have been suggested by local shops here including the Michelin LTX MS and the Dunlop Rover HT. I don't mean to beat the topic to death but I have to confess, I'm a little stressed out over the whole thing considering he Maxxis was the way I was going when I woke up this morning. Any comments in the options I've mentioned would be greatl appreciated.
