Higher than recommended tire pressures good or not?

[UtahPete]

The Spyder tires have a flat profile like a car tire. Higher pressures tend to round out the contact patch. The bike "sits up on the balls of it's feet".

This has a tendency to make the bike feel "twitchy" at higher speeds on the highway. And, of course, the center of the tires wear a little more quickly.

:agree:

Alright. I'm coming in at the tail end of this. I had my first service done not so long ago on my 20 F3L. I experience a shake in the handlebars before I took it in. My shop doesn't have a laser alignment but said it wasn't out and that the handlebars do that. I had the air pressure in my front tires at 15 when I rolled in. They then told me they were at 10. Anywho.... I rode home and it rode great. I looked and they had the front tires at 22. The rear was at 28. Is this ok for the front? The nice label in my frunk says 15.

If you've still got the OE spec Kendas fitted (up front or on the rear... ) then you really NEED to use the pressures shown on your Spyder's Tire Placard, cos those Kendas are lightly constructed & it takes that much air inside them in order to keep the important bits/metal bits safe &/or off the ground! :lecturef_smilie:

However, if you have proper Auto tires fitted, tires which are capable of carrying 3 times the load imposed by even the heaviest Spyder/Ryker if they're inflated to the tire placard pressures, then you not only don't need that much air in them, but you'll be doing yourself & your tires, your Spyder, its ride, traction, steering stability, puncture resistance, and tire life et al a real disservice!! Most Auto tires in sizes that'll fit on our Spyders/Rykers without mods really only need about 14 to 16-18 psi for them to work at their best under our (lightweight) machines! :thumbup:

So do you still have the OE Spec Kendas (or their Arachnid/Eve Rubber clones/alternatives ) or do you have Auto tires! :dontknow:

Generally speaking " handlebar shake " is not an " alignment issue " unless it is extremely off. And that you would notice because the Spoyder wouldn't be drivable..... I also find it a stretch to think front tires at only 10 psi would cause shake either..... However, Kenda's do need more PSI than say Auto tires ..... Mike :thumbup:

When i first purchased my Spyder 21 F3 a few months ago the pressure was 15 Front 28 rear on Kendas. Would get squirrely turning the least amount of in corners until I raised the fronts to 20.
