Lol, we all like big "tires" right?
That depends, does it not?
The size of the tires should be in keeping with the size of the tractor frame overall. New tires made from natural products are my fave. Old tires have been known to sag badly due to a variety of reasons. Too much use, inadequate maintenance, improper inflation, too much UV exposure. punctures from metal objects and so forth can make them quite unappealing. Attempts to use tires as a "canvas" for artwork is particularly repugnant to me. The worst tires are the ones that have been subjected to the introduction of various chemicals to try and expand them or make them flat-proof. Under certain circumstances, this procedure might be justified (such as tire reconstruction) but all too often it is done for the wrong reasons and the overall appearance and handling of the tires just turns ugly.
