As some of you know the 16th will be my first time driving my truck at RC, I have ridden along a few times though. My first question is what psi should I air down my tires to? they are 33 12.50s on 15x10's. At the end of the day how do you go about airing them back up? I don't have a compressor or anything like that. I will have a friend coming with me for the trip, he is most likely going to be my room mate next year at college but he wants to check out the park and see if he wants to bring his truck out sometime. My question is if im registered as a driver and he is registered as a passenger could he still drive my truck some? thanks for the help!
