Make a few phone calls and get some quotes. Be sure to include everything you want such as new valve stems and balancing (spin or balance beads). I agree that you are probably looking at $2,000 to $2,500 depending on tire size
I've had the Toyo 154 tires on my Bay Star since last summer and they are a very good tire so far!
Retired but busier than ever!
