I bet the antique tractor pulls have some tread pattern requirements. Is that so?<br><br>https://commercial.firestone.com/en/agriculture/product/puller?compare_index=361992<br><br>[Dave Maynard] We are not allowed radial tires in the antique tractor pulls and must use bias, which we still can get. <br>[Spencer] Nope - Bias tires are still alive and well. Not saying that’s what anyone should buy, but they are still widely available. <br><br>[James Peck] Are all rear tractor tires now radial<br> <br>https://www.carlislebrandtires.com/our-products/product-detail/large-radial-tractor-csl-28<br> <br>Firestone claim they introduced the 23 degree design in 1950.<br> <br>https://commercial.firestone.com/en-us/agriculture/solutions/traction/23-degree<br> <br>[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<br> <br>[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<br> <br>[Mike M]What's the difference between 45 and 23 degree, other that the obvious?<br> <br>[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.<br>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.<br> <br>[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.<br>.<br>_______________________________________________<br>AT mailing list<br>mailto:AT@lists.antique-tractor.com<br>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com<br>_______________________________________________<br>AT mailing list<br>mailto:AT@lists.antique-tractor.com<br>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com<br>_______________________________________________<br>AT mailing list<br>AT@lists.antique-tractor.com<br>http://lists.antique-tractor.com/listinfo.cgi/at-antique-tractor.com<br></body></html>
