i just bought a new 44" craftsman zerorturn and the back tires tear up the lawn everytime i turn anybody know wat kind of tires i can buy for this not to happen?

Try to not turn 180 degrees at a high rate of speed. Slow down if this is how you want to mow. I would recommend turning 90 degrees, then backing up a little, then going to your next line. This prevents the whole machine from pivoting on that tire completely around, which is why you're tearing up the grass. Good Luck!!!
