It wasn't on the net...it was in one of the multitudes of trade papers, magazines, technical junk-mail....that pile up at our regional office. It might have even been in a tire-flyer ad. I agree with the concept that the taller tire has a longer contact patch, but on a round section tire I'll believe it gets narrower...meaning maybe the same contact (pretty close) if tire pressure is the same between the two tires (unless maybe way over-inflated?)
I am convinced that the taller tire seems to track straighter...I got a used motorhome that has 19.5" wheels, where my old one had 16.5"; the tires are really tall and very skinny...and it's a LOT less work to drive straight than the smaller, wider aspect tires were. Of course...it's a big difference between 58mph cruise speed and 158!
This whole concept has me scratching my head, hoping to someday build a lakester and trying to figure out tire sizes. I think I'll go with whatever I can get free or "inifo" as they say in the streets!
Very interesting thread...still learning I hope.
