I've checked the speedo and it has me faster than actual speed by about 4 MPH. So if it picks up son speed, I would be happy. This vehicle is terrible in snow (FWD) so after extensive research, I really want the Kuhmo SAT KL61 but is on national backorder till somtime in Jan. The Mich LTX MS2 is a close second and is readily available. So if it fits...life is great.
