I've got a chance to pick up on some new Goodyear Wrangler All terrain Tires for under 50 dollars each. They are LT265/75R16 Load Range C (2,469 pounds @ 50 psi) or LT265/75R16 Load Range E (3,417 pounds @ 80 psi) to which I'm at a loss to know which would be the better choice for my long bed Frontier. I do some trailer towing but no where near enough to warrant the load range E tires but at under 50 bucks each I'm tempted. I know you can air LT tires down to improve their ride when not towing but how much can you air them down, can I run them @ 36 psi like the stock p-metrics? Looking for insight and opinions please...
