[AT] tire brand

[farmallgray at aol.com]

Usually you can use any stock tread pattern but there are different classes based on whether the tires are "cut" (sharpened) and whether they are just sharpened by tapering the bars (called top cut) or by also cutting the leading edge of the bar or even cutting a new bar in between. There are also what are called double cut which end up looking like the Firestone Puller 2000 on the web link posted earlier.

Many tractor pulls do not allow Radial tires. Only bias ply. I'M NOT AWARE of any tread pattern restrictions.

Firestone is making a bias ply tire for tractor pulling. I bet the antique tractor pulls have some tread pattern requirements. Is that so?

[Dave Maynard] We are not allowed radial tires in the antique tractor pulls and must use bias, which we still can get. 
[Spencer] Nope - Bias tires are still alive and well. Not saying that’s what anyone should buy, but they are still widely available.   

[James Peck] Are all rear tractor tires now radial

Firestone claim they introduced the 23 degree design in 1950.

[deanvp] Did a quick search. Firestone advertised better road life and slightly better traction. But 45's were better on side hills. And shed mud better
 
[deanvp] I can only offer my limited experience with the two. The 45 degree lug sheds mud better but the 23 degree lug offers slightly better traction
 
[Mike M]What's the difference between 45 and 23 degree, other that the obvious?
 
[John Hall]  OK here is the latest. Getting rims local, about the same price as you can get anywhere on the net by the time I add shipping---plus I need them NOW.
Talked to 2 tire shops. Leaning toward the closest one. I'll have them mount the tires on the new rims. I'll then put them on the tractor and add fluid. Leaning toward a Carlisle--I had no idea they made any thing besides lawn mower tires. These tires will be a 45 deg angle, not 23. Replacing a set of multi-angle Safemark. The other option is tires made by Galaxy.
 
[John Hall] Looks like I have to buy 2 rear tires in a hurry. Anybody bought a particular brand the in the last few years that you are happy with? The cheaper the better--got to buy 2 rims as well. Rims made it 47 years and have stress cracks, the tires are 60-70% tread, but at 28 years old they have dry rotted.
