    Default Another Tire Pressure Question.....

    I'm not asking what pressure you run your tires at...What I'd like to know is how large a tire pressure difference between your two front tires do you consider safe or comfortable? In other words, at what point do you feel you need to even out the pressure readings between the two tires?

    Just Curious....

    Thanks!

    I usually keep them the same, not really difficult. I feel better about it.

    The reason I ask is that mine consistently differ by 0.4 lbs. Cause for concern?

    Not to me. I consider that small a difference to be the same.

    You have a very good pressure reading device to measure that. I'd call it the same pressure for the ballpark I play in.

    I use the cordless digital tire pump that Lamonster used to sell, before any long trips I just check/topoff all tires. Though I agree with others that 4 tenths of a lb wouldn't be a concern.

    Tire that's on the sunny side might register 1-2 psi higher. Make sure you measure them cold and in the shade. Pressure should be equal.

    RTFM! It says w/in .5 PSI. Do as you please.

    I believe BRP says to keep the front tires within 1/2 PSI of each other..... Jim

    BRP says,
    NOTE: The pressure difference between the left and right side tire should
    not exceed 3.4 kPa (.5 PSI)
    .

    It says the same thing in all the Spyder and Ryker owners manuals.

    It really is not a matter of personal preference. Experiences reported by owners on here indicates that you need to keep them within 1/2 PSI of each other or the "feel" will be off. What many report as "squirrley" or "wandering". The closer the better.

    Explain that, please.

    Is that testing cold or HOT ?
    If they are the same cold but slightly different when HOT, that usually is not something to be concerned about.

    If one side is losing pressure, you need to get that fixed.

    I know that during my tire testing phase of the Car Tire Swap and ensuing nervousness, I measured pressure and temperatures until I was sick of it. On a good 1 hour run, one tire would almost always be at least 1/4 to 1/2 PSI different. This is due to the road conditions, mine changed sides frequently as to which was higher. So check your pressures cold, before you roll the bike for the day. Then run it like you stole it!

    As someone else mentioned, which side the sun is shinning on makes more difference than you might think.

    Default Depends...

    The recommended difference will not be noticeable to many on normal ryding. Where it becomes noticeable will depend on ryder and style. The half pound is minamal as the tires will not be the same once rolling out there. I use the dual fill system which gives me an even start when filled in the garage cold....

    I always check the pressure COLD before starting out. That's when I was finding the 0.4 PSI difference. I took the time to even them out exactly before ryding today and I think I noticed an improvement in ride quality. Maybe it's the placebo effect.

    Thanks, guys!

    It's the placebo effect ...…….Mike ...…….. PS people CLAIM they can tell 1-2 lbs difference in PSI just from riding on the tire , however if asked " would you bet your life on that being a fact " , no one says yes !!!!! ……….. Even professional Race car drivers can't tell …… Mike

    That is an absurd statement to make.

    Professional Race car drivers do not drive Spyders.
    And they often "adjust" their pressures in HALF POUND increments so they can certainly tell the difference.

    AND......if my fronts are mis-matched by 2 PSI, I can certainly tell the difference.

    To repeat: IF......the same tire is consistently losing pressure......that is, you equalize them and the next time you check the same one is always down a bit......then you need to get that fixed because it likely won't fix itself AND might get worse as time goes along.

    ..... Danica Patrick does, since She drove at the Indy 500 ( among other events ) I think that qualifies as a " Professional Race car driver " ……………….your welcome …… Mike
