with stock tires, i have had no problems in mud or snow. the only time i ever got stuck was in a mudhole covered in water that big trucks with huge tires had been going through. i got hung up in their ruts and bellied out. the day before that i went through it with no problems. this mud was deep enough that the pipe was girgling and i thought it was goun to drown but i kept it running and got pulled out. i am also glad that nothing got in the belt drive housing. i just got hilifter springs and a super atv lift that i am getting ready to install. i just bought 27" dirt devil xt's this morning, cant wait to get them on and get pics for everyone. i believe that now i will be able to get through just about any hole the trucks go through!
