Looks like them tires have the full amount of air in them. Drop the pressure down to about twenty five pounds each on the drive tires and let the tire work for you....pulled many a four wheel drive out when they got stuck while I was stationed at Fort Hood,Tx. All I had was a C-10 chevy two-wheel drive and a very heavy rope about 25' long. Try it some time, it works very well. just saying....
