In my case, I was using a pair of 2-1/4" Dave Brown's narrow lite wheels, and it lasts about 30+ flights before needing the wheels replaced. The second set of wheels, instead of going with the same setup, I went with a pair of Bolly carbon wheel pants so standard wheels can be used, and this pair last for 120+ flights already, and that is what I am going to do with the second Integral also.
