I posted the other day that I was putting new rear tires on my JD GX75 rer, well I did replace them and a few days later I mowed and noticed something that has been bothering me for the last couple of years. The problem I was having was when I turned sharp or too fast the mower would kind of gouge to one side, I had checked all the height settings and the deck wheels for wear, I could not find the reason until now, after putting on the new tires the problem was gone, the side walls on the old tires were weak and would flex and sag, causing the problem, I fixed my problem without knowing it. :laughing::laughing::confused2:
