I've been reading about the pros/cons of running over the tire tracks, and have come across concerns about extra strains imposed by tracks over, at least, solid tires. Have any of you had a chance to put many hours on over the tire tracks while using normal, aired tires? I am about to receive (getting itchy!) a new JD 332 and am considering using tracks on occasion, but when I called my dealer I got "We don't even sell tracks. Too many warranty issues." That was a bad omen. Experiences w/ aired or solid tires and tracks? Does it make any difference what type of track tread (steel, rubber, etc)? Thanks. j
