I have 12.4-38 rear tires on my H. These tires have to be at least 25 years old as there is a lot of dry rot and almost no tread left. Rubber is very hard.
Just this morning I was trying to reseat the bead on one of them because it loosened up during tractor pulling. I used bead sealer. When I aired it up to 35psi it blew off the rim. Upon examining the bead I noticed a slice in the bead. This is probably how it popped off the rim. Looked to be existing damage.
So now a fellow puller has offered me a nearly new set of tires. I believe they are 11.2-38. My thought is they should mount on my rims fine.
Do they measure tires different now than 25 years ago? He says by looking at them they appear to be the same size. Does anyone think going from 12.4-38 to 11.2-38 will make a negative difference in pulling? Going from a tire with almost no tread to ones with great tread might help as most tracks around here aren't super hard.
