What happens here

Inspect the mower's tires, especially the rear ones, for significant wear or flat spots. Even if tires appear to be the same size on the sidewall, their actual circumference can vary significantly, especially after wear or if they are from different manufacturers. A difference in tire circumference can cause the machine to pull to one side, leading to tracking issues and excessive wear on the hydrostatic drive system. If a tire needs replacement, it's recommended to replace both rear tires simultaneously to ensure matched circumferences. If only one tire is replaced, or if the existing tires have different circumferences, you can attempt to stretch the smaller tire by over-inflating it (beyond the manufacturer's recommended PSI, cautiously) and allowing it to sit in the sun before deflating to match the larger tire's circumference.

Goal: Ensure even tire circumference and condition to prevent tracking issues.

there so if you flatten entire cut it chance of me buying the exact same one was on there pretty rare yeah okay so if the guys go out and put a new tire on they puncture one even though they're put in the same size tire on that may not have the same circumference it says it's the same size on the side of the tire but it doesn't necessarily mean it is actually the same size okay so this one here with 73 inches yeah 71 okay so if I try to put these on the same one that's the same tire they're two inches off so you can stretch it out you can't trinket so you've got a strict suit you've got two tires your track your machine's not tracking right you measure the circumference of the tires and then whichever one is bigger you've got to take the smaller tire blow it up beyond what it's rated psi is leave it set in the Sun to expand it out and then put it back down and then put it back on right so the tires are no different than a bag of balloons right you're pulling out they're not the same size you blow it up and you stretched it out yeah it's rubber you guys can probably get a machine to track straight going forward the problem is when you put it out into the neutral now this pitaya is going to be trying to roll backwards and you set my parking brake you're gonna start burning up the hydro what what all the guy was trying to do is get his machine the dryer straight he burned up tiger I had no clue all right thanks Fred that's for blowing my mind one more time
