Let me know DDS. Always looking for some replacement parts for my cat. As far as the aluminum wheels are concerned Alaska Snow Cat, I really don't know what is better, so thanks for giving me a thumbs up in the comparison between tin and alum. The later looks much better on my cat, but I can go either way since I have about 50% alum. and tin right at the moment. Need a few replacement tires. Oh-forgot to mention the size that I need! They would be 4.50 - 12. Mine are Goodyear Monorail tires, but anyway, I need a few new ones to replace the well worn onec of my cat. Thanks!
