So, the mantra of SpyderLovers.com is to just believe only what you say? How does anyone feel comfortable with posting next to your red font, over use of emoji's, and self-aggrandizement?
Do the moderators of this forum not WANT discussion? Surely, this is not the first time for someone to complain of this treatment.
Newbies: just do what he says. He has more posts than me and has won a sanctioned drag race with a Spyder. I've never questioned his "training," whatever that may be. But, it is impossible to have an opinion as long as it is not the same as his.
But, when someone is actually trying to show that the tire pressures that I have set, and others have set, actually work FOR US, I get the RED FONT treatment and emoji explosion.
Peter Aawan.... do you not agree that tire temperature readings matter regarding inflation?

I am not an expert on tire pressures, but I can read recommendations from expert organizations. I just read the U.S. Tire Manufacturers Association free publication titled, "Care and Service of Passenger and Light Truck Tires."
Excellent information! You can find it here.
I did NOT realize how concerned they are about UNDER inflated tires! You will read for yourself in multiple locations where they WARN of under inflated tires and the potential of internal damage from HEAT build up.
There are WARNING boxes through out the article like this:
Warning Tire Pressure.jpg
Woah! It seems to me that if the US Tire Manufacture Association goes THIS FAR to make a consumer awareness article, they would say EXACTLY what they are concerned MOST with! In MANY locations it discusses how under-inflated tires is a great concern. Even in the big WARNING box above it says that! The warning box says over inflated tires can have higher chance of puncture. Hmmm.... What the heck?
Why would they have not listed traction control with higher pressurized tires in that warning box? (Maybe that isn't their primary concern!)
How does anyone truly KNOW if 14psi is NOT TOO low for these CAR tires on our MOTORCYCLES? Where does that number come from? Studies? Repeated cross-sectional analysis of rubber (natural, synthetic and filler)degradation and tire ply distortion? Or, somebody on an internet forum?
Wow. Now that I've read this entire article, I'm very concerned that too many of us may be under inflating our car tires on our motorcycle. I have no idea, but the US Tire Manufacturer Association has great concerns!
Warning Tire Pressure under inflation.jpg
ANOTHER big warning box in the same article! It focuses on three things:
1. Underinflation. Don't do it!
2. Over loading the vehicle. That's unlikely with our Spyders.
3. Consult the vehicle placard. Um.... we are using tires that BRP does NOT recommend! So, that makes it invalid, right?
Down below is the only reference that I found in the entire 54 page publication that mentions over inflation of a tire leading to reduced traction. BUT, how do we know what pressure these CAR TIRES have become OVER INFLATED on our MOTORCYCLE? Are we guessing, assuming, postulating, or examining? My guess is that it is a guess from some individuals on this forum. Granted, it can be an educated guess, but a guess nonetheless. Do you know the measurements for "traction" are done in a stopping straight line and NOT in cornering! Things that make you go hhmmmmm...
Improper Tire Inflation
For optimum service, use the inflation pressures specifiedby the vehicle manufacturer on the vehicle tire placard,certification label or owner’s manual. Under inflation mayresult in rapid and/or abnormal tread wear, improper vehiclehandling and decreased fuel economy. Over inflation canalso result in rapid and/or abnormal tread wear, decreasedtraction and premature wear of suspension components.Improper tire inflation may cause a tire failure, includingtread/belt separation, even at a later date, which can leadto an accident and serious personal injury or death. Checkand adjust tire pressure (including the spare) at least onceper month with a pressure gauge (see “Proper Tire Inflation”on p. 11).
"Improper vehicle handling!" Wow... That's exactly what my butt felt when I tried putting my Yokohamas at 17psi. I even described it with what happened during a turn in an earlier post. It seems that the US Tire Manufactures Association may agree with my butt. LOL.
There was NO reference in the article (that I found) that warns over inflated tires cause heating and internal damage. Just toughness to puncture, and one reference to reduced traction. But, again, how do we know our psi's are putting the tire in an "over inflated" state?
Well, someone will postulate that the recommended tire pressures by the manufacturer should be followed. Um, OK. the manufacturer doesn't put these tires on our vehicles, AND there are plenty of reasons why that recommended inflation amount MAY NOT be the optimal tire pressure. They can be influenced by other things besides performance. That's another easy internet search away for those that want to read.
So, my take on reading this article is that LOW PSI tire users should REALLY monitor their heat build-up. It can degrade the tire components internally, and you may not realize it.

 ....Thank you for this information it is enlightening to say the least ...... I am now going to inflate my tires ( car tires ) to the Maximum recommended on the sidewalls ( about 44psi ) ........... annnnnnnnnnnnd you have convinced me that all my training from so-called Experts in this field have been throwing BS big time and I will dis-regard anything they taught me  ........My big regret now is I can't undo all the Court rulings that were decided on my testimony by Juries  .... I'm also contemplating returning the 10's of thousands of dollars I received in payment for my " ALLEGED " Expert testimony..... You should be VERY, VERY proud of yourself for un-covering this massive hoax that I've been perpetrating on our fellow Spyderlover's ..... I do have a question though .... In the " US Manufacturers Association's 54 page publication about Care and service of Passenger & light truck tires .... I didn't find any mention of lightweight ( or otherwise ) Can-am Spyder's ....WHY do you think they omitted that ..... your response doesn't have to be Fact based .... In your case a GUESS will do ........ Mike

What happened to your red font? Has someone asked you to tone it down?
Never never once has there been a recommendation of inflating a tire to the maximum pressure listed on the sidewall. Good try putting words in mouths.
Self-aggrandizement once again. I think it is great that you made money! Fantastic! You are a very important person that is highly favored.
But, still no studies to back up YOUR claims either of very low tire pressures of CAR TIRES ON MOTORCYCLES. Did you testify regarding this? Please... a case number and court date. I'll be glad to read. CAR TIRES ON MOTORCYCLES.
The absolute FUNNIEST thing to me regarding this tire pressure thing bending you out of shape:
you are actively PROMOTING a suspension link that changes the GEOMETRY of the entire suspension system. You are doing this in your garage. People are supposed to rely on their safety because you testified in a few court cases on accident investigation?
What tests have you done on that suspension linkage? What happens if there are major problems with linkage wear or problems with the lubricated pully system? Metal fatigue analysis? If you are NOT doing studies YOU ARE GUESSING too!
Are you LEGALLY prepared to handle lawsuits regarding your tampering of a tried and true suspension developed over many years by true engineers of the field at BRP. You're a retired cop, or something, right?
You can't make this irony up.

I have been wondering for a long time......why don't we have solid tires? Why do the tires manufacturers bother to publish tire inflation charts? ..... with rubber filled tires we would avoid tire flexing, overheating, tire puncture....and all the likes.!!!!
Also, another question for you, on those little, as light as possible cars called F1, why don't they inflate the tires to 35 - 40 psi. That way the tires won't heat, right. Ha darn, another question, why do they take time to do warm up laps to bring the tires up to operational temperatures.....???? just wondering.....
PLEASE HELP !!!!!  save us all....!!!!

LOL. Richard. The idea of not using a pneumatic tire is ridiculous, and you know it.
You analogy to F1 racing is invalid. How often do they change tires, or go through tires? One set of tires may be ripped out in one race.
I'm not trying to save anyone. I'm trying to have a discussion that low psi in our CAR TIRES ON MOTORCYCLES may not be the only option.
Good use of multiple emojis, though.

Sorry, but the analogy to F1 is quite valid.!!! Very light vehicule on big tires. That equation means low psi.
A tire is built to be flexible. As a matter of fact, the rubber compound is built with a lubricant in it that is released by heat and flex of the sides during usage. This prevent the UV and the ozone in the air to dry up the surface of the tire, and prevent sidewalls cracking.
Flexibily is also used to absorb shocks. In your area, where the road are smooth as silk, you will not damage your Spyder. But don't come up north, where the road freezes during winter. We ride on cracks, bumps, potholes, expansion joints out of alignment. With tire hard as rocks, not absorbing the "all of the above" you will kill your suspension bushings as well as your shocks absorbers in no time. (without talking about comfort and rattles that will start to show-up)
There is a consensus in the tire industry that 4 to 6 psi increase with heat during usage is normal and required to get the tire to perform properly. So your goal should be to get to the pressure that will provide you with the wanted temperature increase. You want a proof? Why do the recommand to check tire pressure in the morning, when tire is cold and didn't roll for more than a mile.....?!?!?!
This reply is for general knowledge for peoples researching proper information. It is in no way an escalation of arguing to win the contest.
Hoping it will help Spyder lovers riders to make the right decisions......

LOL. I can only imagine Moms and Pops riding two up through the mountain roads with their tires set JUST LIKE F1 tires! Soft, flexible and low psi and TRYING to get them up to temperature. That would be a sight to see. That would be a FUN ride for her as she's screaming into the microphone at him for the squirrely driving and him yelling to get off of his back.
F1 cars and tires aren't used the same way like people use their Spyders.
I'm still waiting on PROOF from our so-called tire experts here that 14psi is proper inflation of a CAR WHEEL on a MOTORCYCLE. Actually, I'm not saying it is NOT, but to just throw out that any higher pressures are going to lead to ULTIMATE DEATH and PERIL is comical. "Wear your leathers!" (That comment seriously cracked me up..... like I'm racing on a BMW hpr race motorcycle... LOL. We are on a three-wheeled vehicle with monstrous wheels. It's a big reverse trike! Get real, folks!  )
It's absolutely hilarious to me because the band of low-pressure merry men still have NOT shown or proven the EFFECTIVE pressure range of CAR TIRES ON MOTORCYCLES, but they are quick to judge anyone that jumps off of their mantra on SpyderLovers. Then, it's even funnier to me when I use their recommendation for monitoring the tire heat, it still isn't good enough for them. Peter, I'll be glad to link your posts on that if you need.
I'm no tire expert. I've never over-emoji-ed and kicked and screamed like an infant to get me to listen. However, I've gone to resources to find some answers. I don't care if someone has their tires at a lower pressure than mine! But, I find it VERY condescending to say that I can't judge the way my vehicle responds with varying pressures. That's laughable to say the least when tire pressures are adjusted on every pneumatic tire in every vehicular mode of transport.
All I know is that the US Tire Manufacturer's Association has GREAT concern about LOW PRESSURIZED tires, and they give little description to what "over inflated" will do. Do you not recognize the US Tire Manufacturer's Association as a reliable resource?

Oh, and how do you not know that my 26psi tires are NOT flexing and engaging the road? You don't.
I've at least tried and compared what the handling characteristics (that's a US Tire Manufacturer's Association term) are at various psi's. I can very much flex my tires at 26psi's. My butt can feel it! LOL... My butt can also feel the tires at 14 psi feel like they are going to come off of the rims, or be pinched at the bead.

What you don't appear to have realized yet, is that about 5 posts ago I figured what type of person I was dealing with ....Since that revelation I have just be " SCREWING WITH YOUR MIND " ...... I haven't had this much amusement on this Forum in ages ...annnnnnnnnd I'd be very happy to answer all those questions and any others you can think up .......... As long as you pay my going rate for EXPERT Testimony .....When you take your Spyder for service etc . are you surprised when they give you a Bill for their work ? ? ?..... annnnnnnd you haven't answered my Question about - WHY - Spyder's weren't mentioned in your " Holy Grail " bulletin that you love to quote ???? ..... Do you know the answer ???? ....... Mike

......... and instead of thinking up cute Attack verbiage, take the basic course in " Accident Investigation " .... and if you pass it ....take the " Advanced Investigation " course and if pass that, you & I can have an " Intelligent " discussion about tire pressures..... But if you take these courses you will understand and also agree with me on what I have been recommending...... However I'm SURE you will have something less than enlightening to comment about this post ....... Mike
