16" Wheels

When people are talking about tire availability. Its in performance tires cause you can get competition tires in any size rim
But lot of performance tires don't come in anything under 18" and if the do the 18" 19" can go from 205 to 355 and every step in between. Where as 16" and under will have just a few sizes and more likely between 205 - 225 and a few above which is fine for most of us.
