I'm running 17 lbs and the bike handles great. You can run what you feel comfortable with, but in rain you will see the difference. Also I feel 17 lbs sticks better in curves than the higher pressure. But like I said each to their own.

I disagree about the rain. I've run 25-26psi in many different situations. Even tried to skid them out in a wet parking lot, and couldn't get it to happen. My belief is that it is speculation that it will have an unsafe characteristic with this type of psi. I know that I run my RT a lot harder than probably the 'average' Spyder rider. I still can't get them to slide. But, I can get 14psi to mush around like wet socks.
Someone is dying to get out on this subject.... and, 3....2.....1......
What you said above about Kenda's is very much correct .......... Kenda's are weak compared to Auto tires ...... But high psi in auto tires will lower their traction also and for some of the same reasons ............Mike :thumbup::thumbup:You haven't said what kind of tires you have.
If they are stock 2 ply Kendas, then 30 PSI will round out the profile, minimizing the contact patch.
It puts the bike up on the "Balls Of It's Feet" so to speak.
This makes it much easier to turn. The bike seems very responsive.
Until you go out on the highway.
At highway speeds, that much tire pressure will make the bike seem twitchy, and almost uncontrollable.
Also, by rounding the profile, you create excessive wear, necessitating early tire replacement.
The minimum contact patch won't be helpful in the rain.
But, it's a matter of choice. If you're comfortable with the feel of the bike and your style of riding, then go for it.
The tires won't shred or fall off the rims.
And if you're NOT running the stock Kendas, and have a different brand, then I don't know what I'm talking about and everything I said could be wrong.

Anyone tried 50 psi yet? :roflblack::roflblack:

My rear Kenda did 17K (below) but my front Kendas still have at least 25% tread-life remaining at over 45,000 miles! I run the recommended 18-22psi in them....My stock Kenda tires are doing awesome. 15,000 rear and 20,000+ for the front...
Sorry R.K. but #1 & #2 are wrong, plus #2 doesn't make sense !!!! ..... Kenda's are weak because they don't have enough plies or strong enough plies to support more weight ............. and concerning Braking distance vs. cost ..... 1 inch of braking distance could mean $1000.00 plus in body panel damage ....annnnnnnnnnnd your Kenda Spyder tires ....NEEDS those psi's because it is a weak tire, and has nothing to do with tread compound...... Mike :thumbup:Kenda's are "weak" only because they have a softer rubber tread....because the machine they support is lighter.(to maintain traction)
Car tires are stronger....... because the machine they support is heavier.
My stock Kenda tires are doing awesome. 15,000 rear and 20,000+ for the front.
No need to risk extending my breaking distance to save a few bucks (or risk an accident).
What I'm reading on the use of car tires is why dealers, car tire manufacturers and installers mandate a waiver be signed.
BTW....I keep my awesome Kenda tires at 19PSI front and 28PSI rear.
19 in the front cause I installed the Baja Ron sway bar which eased up on the steering effort.

Kenda tires are not "weak"....they have a softer rubber compound because they need to stop a lighter vehicle.
The reason tire manufacturers will not list certain vehicles is due to the weight of the intended vehicle.
They know from their research a stronger tread on a lighter vehicle causes braking distances to increase.
Your complete lack of knowledge is why there are waivers to be signed or flat out denial of a tires sale.
You are a classic example of a know-it-all who does something then blames it on someone else...(why waivers need to be signed)
Stop pretending you have a clue and are smarter then the engineers/scientists who develop both the tires and its use.
Log onto any tire website, they talk weight ratings.....not too many cars out there that weigh less then a 1000lbs Mike.
Why have you decided " Attacking me personally " proves or bolsters your theories on this subject ???? .... I'm not a " know-it-all " and I resent the inference..... the views I express on tires is based on my Schooling and training in the subject. I have testified in Court about what tires can and can't do based on my knowledge. It's known as " Expert witness testimony " , NOT - " know-it-all testimony ". There are people who THINK they know what they are talking about .....and a couple here who actually KNOW what they are talking about............ Everyone has the right to believe what they want, the problem arises ( for me ) is when they make statements that are Scientifically false, and that information could potentially hurt people ..... I will never argue with anyone who states that red ( or blue - white - yellow etc. ) is the best / nicest color, because it doesn't matter. But tire " PSI " does...... My message is about safety ..... frankly I don't know what your message is ............
