I found there is an improvement in lateral stability with E rated tires, but if you only tow for 2-3 weeks a year, IMHO the P tires will be fine as long as you stay within the weight ratings. As for gas mileage, I didn't notice any difference between the P type and LT / E rated type.
Thanks for the info. I'm likely going to wait till spring before getting new tires but will keep what you said in mind.
I did find a set of Cooper Discoverer AT's that are rated as C load LT's. The load rating is 116 whereas a set on Michelin P rated LTX M/S 2's have a load rating of 114, so not much difference according to that, but would the sidewalls be stiffer in the Cooper's being they are C rated LT's?
