You're right it is a great point. Nobody has said to run max pressure but rather an appropriate pressure for the load. By saying I would end up getting hurt testing high pressures shows perhaps you're not quite the expert you would have us believe.
Yes, exactly.
However, I respect their opinion, like anyone else here, but despise this internet group think when they know they have no science with all of this.
They can just say:
these car tires can withstand lower pressures because they aren't carrying the load as a typical car.
Seems reasonable enough, and I rode like this for thousands of miles. But only when I increased my pressures and dialed in my suspension, did I find out that the Spyder was so much more than it was. "Twitchy" issues had more to do with symmetry and balance, and technique. Lowered pressures just masked it for me.
You see, there is also NO science for what they claim about lower pressures! They just proclaim it. For instance:
The design of a tire is made to have SOME air pressure so that the belts, bead, side wall, rubber compound, and tread support the vehicle and have traction. Plus! It is in MOTION. It rotates, accelerates, decelerates, TURNS, stops, and starts.... Lots of physics just with those actions. How does ANYONE know that low pressures in tires do not affect any one, or all, of those things in a negative way?? The ONLY thing they have, and higher pressure users have for that matter, is:
"well, I've put xx,xxx miles on it and no problem. Tread wear is great.
That is anecdotal evidence. That is not science.
What about heat generation with "increased traction" of lower pressure tires? Well, I would hypothesize that more surface area to the ground =
more friction =
more heat =
more pressure increase inside the lumen of the tires.
Therefore a larger range, or delta, of possible tire pressure in various conditions: road condition, weather, heat index, time, speed, etc.,etc.
Could the change in tire pressure be an issue for some? Maybe it isn't an issue at all? But if you scream loud enough, proclaim butt science, and abuse emojis it becomes science.
The group think is this: lower pressure means safety. But, you don't know. Just speculation. And, even if you're right you don't know what the RANGE of safety is with PSI is with car tires on Spyders. So, we ONLY have anecdotal evidence on a web forum. So, I'll add to it:
I have Yokohamas x 3 and have 10,000 miles on them. Run 26psi up front and 28psi in the back. I love the way it handles and have not had one problem riding through windy rainy roads or 99+mph on highways.
