I use Marathon Supreme tires but I didn't pay retail for mine... dunno if I would spring for them otherwise. I've had good experiences with kenda's puncture resistant tires as well as gatorskins. I have no idea what is on the LHT now but I'd assume they'd be alright to use rather than just buying new tires. Ride out in the lane where the car tracks are you'll be less likely to flat. I seem to have good luck regardless of the tires on my bikes.
