coldcanadian- I had SIX flats on my new rear tire on the SC before I got it to hold air. I had the tire store do the tire and tube mounting- but the pulling the tire off of the tractor was my job all six times. Trust me- for the amount of work involved- $26.00 for a new tube is peanuts. You can buy large tire irons at Norther Tool. They sell the kind with the "lip" that rests against the edge of the rim while you pry the tire up and over the edge. Having seen SEVERAL tubes go "POP" upon inflation- I offer the following advice: 1) soap the inside of the rim up with tire soap before you install the tube. 2) carefully align the tube by hand to make sure it is not pinched or wrinkled. Be sure that the valve stem is correctly aligned. If it is slightly off- the pull when it's inflated will puncture the tube. 3) slowly inflate the tube halfway to allow the tube to straighten itself out inside the carcass of the tire. Then deflate. (your small compressor may not have enough oomph to move the tube around) 4) then do the final re-inflation. With any luck, you will not hear a BOOM upon inflation. (grin) I don't have any special advice on breaking the bead of the tire except using a tire hammer (a sledge with a wedge shaped end.) It's very easy to miss the bead and bend the darn rim- so take your time. I've seen the tire guys pour soapy water around the rim while the tire is laying flat to help this process. After the bead is broken- I just walk around the edge of the tire to knock the rest of the way off the rim. Good luck- and don't get hurt horsing that big guy around! -Schotte
