Hey, so i'm planning on taking my truck on the beach this weekend on Long Island at Robert Moses, to Democrat Point. I'm buying the surfing permit tomorrow. Never been off-roading before but I hear this truck is quite a capable light, off-roading vehicle. I've bought a Viair 90p air compressore, a shovel, and traction mats in case I get stuck. I'll be going with my buddy who has a jeep wrangler the first time in case he needs to tow me out if I get seriously stuck. Not going to take it anywhere close to the water. Just need it to get me to the jetty to surf. How low should I go with the tire pressure? permit specifies airing down to half the maximum rated tire pressure. I have michelin premier LTX's 275/55R17 with a maximum rated pressure of 44psi. What do you think I should air down to? If I go too low is it possible to do damage? Any other tools you think I should grab or tips you can give me? I know to turn esp off so power is given to all 4 tires equally and to engage low range mode to increase power to lower gears since I will be going slow.
