Carlisle Turf Saver tires last me 1 year. That has been approx 1000 hrs is all. Now I do not know how many miles that is as my mower does not have an odometer. Well first off they are as expensive as a cheap 13" car tire that would get maybe 40,000 miles on asphalt, concrete, gravel, and dirt. I'm guessing I traveled 400 miles on grass or soil and maybe 30 miles on concrete and asphalt. So what gives? This is the best they can do? I just don't get it. My conclusion is that it doesn't effect the homeowner. As for us 1 year is equal to a lifetime for the homeowners lawn tractor units. Not really a money issue for me, you know whats $70 a year. Its more of a inferior product issue. But also if I can save $70 a year on other products to it certainly would add up to substantial savings. Oh yeah if you get longer life out of your tires, please tell me what I am doing wrong.
