"Quick change" and tractor tires are mutually incompatible. With the medium to larger tractors, just moving aound a tire/rim assembly is a challenge. R-1 tires (aka AG tires) have the coarsest tread, and hence most traction, but they will most definately tear up a wet-damp lawn, and depending on the weight of the tractor, can leave noticeable imprints on soft ground or plush lawns. FORGET about running a tractor with R-1s in 4WD around a lawn (or if you do, make very wide turns). Next up are R-4s (aka Industrial tires) that have a bit less coarser tread and, for reasons unclear to me, the thickest tread on tractor tires (supposed to be the longest lasting tire - as, unlike AG tires originally designed for soil contact, industrial tires were designed to spend much of their lives on pavement). That's what I have, a compromise between traction and ground inprinting. A loaded R-4 will hold pretty well, but will, like R-1s, tear up wet/damp lawns and should be used in 4WD on lawns with caution. Turf tires are for lawns, golf courses and the like, and work very well for that application. As to running turf tires through deep mud or similar - good luck - but that said, if you've a FEL or back hoe to help pull you out of trouble (and I've needed my FEL on many occasions), then maybe you're OK if the main deal is lawn care.
