Finally got around to getting some slow leaker and some tires changed around that I have been putting off for a while now. I have a new firestone radial to go on the 1850, I think the 1550 needs a new tube, and intend to get two new tires for the 1655. Question is should I invest the extra in firestones for the 1655, or go for the cheaper petlas or galaxys or maybe middle of the road goodyears? My concern is anything but firestones seem to weather crack in short order. It is pretty hard for me to keep tractors out of the sunlight year round as I often have loads of square bales in my tractor sheds waiting to sell or get unloaded thruout the summer. I think I have answered my own question, but it might be hard to dig that deep in my wallet tommorow when I find out what firestones are worth? Anyone have good luck with anything but firestones? I probably wont go for radials if they are much more than bias. The only reason I have the radials for the 1850 is they came with a deal on a tractor.
