Any thoughts on whether or not a tire brush is worth the expense? I have gone thru some local washes with tire brushes and did not notice a huge difference.
A tire brush will not clean the entire side of a tire, anyway. If you think of the sidewall as from where it meets the wheel, to where it meets the ground - the curvature of the sidewall and the fact that the tire brush itself is round - at best you'll only cover the middle third or maybe half of the entire sidewall - even less for larger tires. .
MMM yes, and no. With traditional tire Brushes, perhaps. .
Some years ago I think Mac Neal had a large diameter Brush with the shaft running parallel (instead of perpendicular lik a wrap or side wheel) to the direction of vehicle travel on each side of the vehicle. problem was with them getting hooked on cars. Some got dragged into the street.
Yea the horizontle rocker as I call them aren't popular at least not in the US. I think alot of Europe washes have them. Econocraft makes a similar brush but theirs uses bristle or cloth C channel. I've never seen one. I know they put what looks like a lawn mower tire on the front to navigate the brush. Not sure how well that works. I'l stick to tire and rocker brushes.Here is the spec sheet. Looks like the Brush is 28" in diameter. Can't tell how long it is.

Seems the entire lenght is 77"-78" and that's not all brush. If drawn to scale it would seem the brush is about 65". A full size trie needs about 96" for a full rotation so I don't know how this would work. Have not seen one in action in decades. Knew a guy who had something similar at one time. They had issues with the front edge of the car hooking it. On occassion the entir unit ended up in the street.
