Like I said, if you swap them (put left tire on right side and right on left) both tires running in required directionalexinPA, the difference is traction. You are running the tyres backwards so they clog up and don't self clean.
I looked again at my front wheels, and I can get a few more inches by just flipping them inside out so I will skip the front spacers. The stems will be inside but I can live with that. I will put the spacers on the rears for sure for stability.I contacted Bro-tek, they are going to do a custom set of spacers for me on a tractor they do not have listed. I am going to do the fronts as well, just to keep the tires in line.
That's what i did just to fit snow chains. If you flip front wheels change the sides to keep direction of rotation as arrow showsI looked again at my front wheels, and I can get a few more inches by just flipping them inside out so I will skip the front spacers.
