Correct Tire pressure

[goracer]

I know this may be an endless debate like oil but I did call American Honda Motorcycle tech support (866) 784-1870 and they say go by the manual which according to them (don't have in front of me) it states "recomended". I called Michelin and they say go by the manual or sticker/plackard (if their tires are the same sizes as OEM) which both state the same as the maximum full load on the sidewall. OK, so according to my '05 (says the same for '06) Honda CBR 1000 owners manual (pg 138) it syas 36-F/42-R. I have tired lowering 5lbs and the difference is night and day (it sucks). I know other bikes list different numbers for suggested and maximum as well as autos but this is what Honda is telling us. Unfortunately they have not tested the Michelin's even though they are a MotoGP sponsor and their stickers are on my Repsol. They told me they tested Pirelli, Dunlop and Goodrich and recomend the same tire pressure for those.

:ninja: :dontknow: :willy_nilly: :haha:

Like you yourself said, that's maximum load. If you have someone with you all the time and both of you together equal the maximum load, then hell yeah. I just looked at my Michelin 2ct and it clearly says maximum load at 805lbs. So the bike weighs in let's say 460lbs, you got 345lbs to play with. If you weight in at that, then run it at 42. If you and your gf or wife weight in at that, there you go. If not, you can't use that number. If you lower the tire pressure and it feels like crap, then that means your suspension is not set properly.

At the end of the day, it's your bike and you can run them wherever you want to. Just keep in mind overinflated tires will not give you as much traction.

Honda recommends synthetic blend oil in their manual, most people will run full synthetic and get better results. It's just an unbrella recommendation.

The max 35-F/42-R is "is" Honda's recomended tire pressure and Michelin said to go with Honda's recomended settings (but I allready said that).

My suspension is setup fine.

I rode my buddies suzuki GSX R 1000, 2007 model to get him on base the other day and it felt like I was on a girl bike or something I didn't know how else to explain it, seemed like crappy throttle response also!

i run on my tires.....32-34 front and rear. also depends on your riding style and preference.

Looks like that ass would swallow you hole.:eek:

Ummm I use 30 front 29 rear this works at the track with Pirelli dragon super corsas and diablo super corsas pretty much most of the DOT tires I Keep the same preassure for the canyons seems bike turns better feels better and is what tire companies recommend at the track and for me works at the canyon too. But I only ride on weekends don't use the bikes as a every day transportation. But if you use the bike every day 35 front 34 rear is about right. There will be lots of opinions on this one but really depends on how you use your bike how you ride. Remember set cold. Also before every ride you should check preassure, make sure there are no leaks, break lever and clucth works and go have fun.

This is the second time that I have heard the front having more air than the rear in the past week but before that have not heard this at all. A friend of mine recently went to Willow and those guys taught him or told him to use 34 front and 32 rear. I didn't believe him at first but now I'm starting to notice it being used a lot more. Anyone have any intresting theory's behind this? Just trying to get educated here.....

[goracer]

Yeah alot of hearsay. People like to repeat what others say and beleive majority is knowlege. I started this thread for fact. I posted Honda's tech support number to verify. You don't have to take my word either. Oh, both the front and rear max is 42psi. So when people say the front is maxed at 36 it is "NOT" true.

According to Honda motorcycle tech support and their tire tech support as well as Michelin tech support (two techs there also) it is recomended and tested by Honda to use 36-F/42-R and there is no problem with the rear at 42psi. It is not common but not unhheard of. According to Michelin some small trucks are recomended to use max psi.

Anyhow I can feel the difference of about every 2 clicks on suspension and about every 2psi on the tires. My problem that I couldn't resolve was my pressure gauge (made in china) on my compressor is off by over 6psi. I decided to double check with my trucks Procomp (made in USA) gauge.

I understand deflating for track but most people ask for street use. I have found only 1psi gain on 1/2 freeway use and only up to 2 psi for 2 hour high speed freeway use. Honda would take this in to account when they test and recomend pressure.

If you have measure pressure differences from temperature and/or track use please post but list details.

If you have experimented with pressure and have results that you have tested more then once then please post explaining what the effects are and why you prefer it and for what road (canyon, track, hot wather etc).

Example: Lower front pressure will result in a push or understeer.

Out of two forums the only one with concise fact and not sarcastic bull**** Why is there allways a dick reply? I average 2k miles/month. Is that more then your 20yrs of sunday rides?.


According to Pirelli's Kevin Allen, the correct tire pressures for the Corsa III are:

Street: 34F/36R
Track: 32F/34R

I have been using 36-F/36-R with my Procomp gauge. There is less oversteer.

Ummm not sure if you were talking about my post? If you were have you ever done a track day? #2 You asked about tire pressure and got replies. As far as the 30f 29r is what I used and been told to use at track days with pirelli dragon super corsas and diablo super corsas and Michelin people told me the same they actually set the preassure for you at the track confirm on your next track day for DOT race tires. Ar far as what it does bike turns faster and better also helps with temperature as on the track tires get really hot you need lower that's it. I personally use the same preassure on the canyons but that's me you can use whatever you want just like I do and use whatever I want on my bike as far as the street goes I now only do sunday rides. But Ive been riding since I can remember I got some miles but that's not the point. If you don't want answers don't ask questions my o2s what's printed on your bike is what honda uses with their test and works on the street you cant use that preassure at the track specially on a hot day is printed there why you need to ask...

have a nice day

^ that was from the previous page. I don't feel like looking who was sarcastic and would rather end it here then turn this thread in to crap.

Here are some good reply's below. Basically, this should have been one of the sticky's but now this thread is :rolleyes:


When you say recomended what does that mean? driving to the corner store

I personally run 32 psi front and rear street only ( I like my rubber to stick )
The Honda recomended pressures are for tire longevity not for aggresive riding.

If you guys think the Honda pressures are so good fine use them but when you lowside your bike trying to be Nicky Hayden dont say I did not warn you.



Spoke with "Matt" yesterday and today with "Steve" at Honda, both said the same thing. Honda tells you recommended which is max load on the rear. They don't recommend running 42 in front as it will decrease braking performance. They tell you 36F/42R because of liability as both Matt and Sheryl agreed. Matt rides a 06 CBR1000RR and he doesn't follow what he preaches. He runs 30F/32R on the street on Michelin PP 2CTs. He's using a 190/50 rear. I asked him why they would tell someone to follow the manual which clearly states too high of pressures if riding alone, both said the same exactly thing "that's what they tell us to say".

They stated that the numbers 36F/42R are for a fully loaded bike. Matt went as far to say that if you are riding alone and don't weigh around 350lbs that it would be "stupid" (his words) to run such high pressures on the street. He also stated that running pressures that high on the street would make the suspension work differently and harshly, as the tires absorb some of the shock.

I have a call in to my contacts at Pirelli and Dunlop.

Sometimes when people repeat the same thing over and over it's not that they are followers or just believe in hearsay. It's they have experimented and experienced changes with tire pressure. I myself have gone as far as using nitrogen in the tires. No manufacturer will ever recommend that, but it works and works well. Honda doesn't have recommendations on many things, yet we do them and end up with a better bike.

I appreciate what you're doing, it's a very tricky and hard thing to figure out, but most of the people that posted are experienced enough to help out.

That's some usefull info. It has detail. It references the source and states street and track difference. That's all I wanted to post. Thanks to those that did so. :cool:

[salvaje]

I always run street 32psi front and back during the warm and hot days. Once it drops below 60 I like to run 35psi.
What I learned about track or race tires is the recommended psi is supposed to be measured after the tire is HOT. So those who set their pressure first thing in the morning to 30psi are really running 34 to 35psi. After you run the track for a couple of laps than set your tires to 30/30. Made a huge deference my last time out.

you are so right the $hitzuki is just all about top end MPH and bragging rights, they corner well if you are super expierenced but they, in my opinion anyway,s are not forgiving.... like small errors result in big mistakes and they just lack the torque on the lower end AKA girlie bike LOL alright no offense to other riders but I hvae really grown acustom to the super responsive throttle and the torque that throws you off the girl, this is satisfying at any speed :evilgrin:
