Hmmm, my only guess then would be that (I believe) Toyo made this tyre specifically for the CX5 originally? Fortunately, there's several manufacturers making this size now so there's no need to stick with the Toyos. However, if you are only changing two, then it would be best to as you generally want four matching tyres on an AWD car. Put the new on the front, switch the worn to the rear and then next time they'll hopefully all need doing together, in which case you have more choice.
