I used to doubt this, until my last tire change, I went from a 32r17, to a 35r15.
When I first aired down to 10 psi on the 35s, the difference was so stark, I thought I’d lost a shock bolt or something. Much more of a “wobbling on the sidewalls” feeling.
The difference is even more stark when you add Coyote internal beadlocks to a 17".
