Street tire pressure.

STEEL · 02-25-2006, 05:20 PM

Wassup guys? This topic has probably been covered a hundred times, but I was wondering what kind of tire pressure do you guys recommend. For starters I ride an 03 954rr with Pilot Powers. 120 70 17 front and 180 55 17 rear. I usually run 38 psi front and rear. Is that too much? NOTE: THIS IS FOR STREET USE ONLY! Thanks guys!!

BluR1 · 02-25-2006, 05:31 PM

i would say it is too much. maybe try 33-34 psi.

GAMBLER · 02-25-2006, 05:39 PM

38 is cool if your commuting or a big body, get more tire life

way too high for spirited riding

Mustang · 02-25-2006, 10:23 PM

What BlueR1 said about 33/34

DjLuxor · 02-25-2006, 10:34 PM

I usually have about 32/33 or even 30/31, but I weigh 130

I'm around 250lb. Will that matter?

DjLuxor · 02-26-2006, 09:42 AM

yeah, I would stick with about 33/34

qbnito537 · 02-26-2006, 11:04 AM

For the street I run the tires hard… up to 41 psi rear….front up-to 36 psi. Never less than 38 rear. This is not for twisties… just going to work and back.

and i bet you are one of those guys that says dunlop 208zr's suck??? if you run any tire up to 38 psi in vegas you will slip and spin all over the place.
Like Gambler said that is for a touring or commuting tire. a tire like the Pilot Power is better off around 30-34 psi for street and track.

If you guys didnt know with lower tire pressures you get more stick less tire life with higher tire pressure you get less stick higher life. But there is a safe side... too low the bike handles like crap to high you will spin it... Kieth Code has a slide bike and when he teaches guys to slide it they air the rear tire up to something like 60-90 psi so it slides easier.

qbnito537 · 02-26-2006, 07:29 PM

Wait a sec, I didn’t say about his tires (I run Dunlop Qualifiers)… I don’t have pilot powers…. But still 38 psi front (120/70-17) sound too much….

He is asking for street use only…42 psi rear and 36 psi front the max (I didn’t say that, the book says that)

. It gives you the better balance life/traction. I’m usually around 38-41 for regular street riding and I’m used to feel the wheel bouncing and accommodating a little :rolleyes:… again I’m not turning from MLK to Cheyenne at 65 mph

.... just regular Legal Street riding.

I use less (36-34) if going to ride with other bikers but never used 30. May be is useful in the track but I don’t go there :)

That is waaay too high in the rear. Check out BluR1's post again...he speaks the truth. When summertime rolls around and you are attempting to negotiate these greasy Vegas streets with tires aired up that high, you may have a change in opinion. Even at legal, commuting speeds, you may need to execute an evasive manuever. (ask me how I know) I'd rather have some traction in reserve than a few hundred extra miles of tread life.

qbnito537 · 02-26-2006, 09:34 PM

I give it try this summer and see how works the full range 30-42. Hum,… I love the feeling of full tires but may be I start rolling at 34 for safety… right now my tires are new so they are slippery and need that extra traction.

BTW the numbers 42 and 36 are by the manufacture, I didn’t make those out.

BluR1 · 02-26-2006, 09:54 PM

QB.... *I am not saying that you need that pressure at the track i am saying it for the street. *try anywhere from 30-34psi. *the tire has more flex in the sidewall hence more contact patch= better traction(more stick) quicker warm up time. *i am not saying that you are turning onto MLK doing 60+.... *but i bet you that you tell someone that certain tires suck? rite? *and i am telling running that pressure (38-42) will make any tire suck. *

the manufactor of any motorcycle will tell you to run 38-40psi... *they also tell you to up shift from 1st to 2nd at 15mph also.
most new riders feed off of what most people tell them. so i will tell you this.. in a street tire or race tire for that fact the sought after increase in tire pressure comes from heat, say if you have your tires set at 31psi when your tire warms up it should be up by 2-4psi.

next time you ride your bike put your 38psi in it and ride say 5 miles get off touch the tire and see what it feels like (probably not warm) *then try it at 31 for 5 miles and touch it feels very warm (which makes rubber act better) safer ride...

BUT DO AS YOU WANT!!!!

this is no joke.

qbnito537 · 02-26-2006, 10:22 PM

Ok, Ok! I’ll try at 31 and see then at 34 and see the difference...

Wait a sec… and you don’t shift from 1 to 2 at 15 mph? Thad’s because you don’t import karpati (Карпаты) like we did.

qbnito537 · 02-26-2006, 10:57 PM

http://www.dunlopmotorcycle.com/info...warranties.asp

Code:

For high-speed, fully loaded or dual-riding touring motorcycle applications, inflate front tires to maximum recommended by vehicle manufacturer for Dunlop fitment and rear tires to maximum load inflation pressure on sidewall. Rear touring tires must be inflated to a minimum of 36 psi for light to medium loads and 40 psi for dual riding and other loads. Never exceed maximum load indicated on tire sidewall or vehicle capacity load found in owner's manual.

I’m not saying that anyone is wrong… just I post the info…. If you go to the tables that gives you the max pressure for each tire.

R1_Demon · 02-27-2006, 12:09 PM

Steel...

I have an 02 Gixx 750, I'm 258 pounds and I run Pilot Powers on it. I run 32/32 psi for the street and have no problems with that. Your bike will probably still slide a bit on the street if you get on it in corners. NV roads just plain suck azz for spirited riding. Nothing you can do about that. But you shouldn't have a problem with the tires lasting for a while running 32/32 and still have decent contact for the steet.

Just my $0.02 anyway... LOL

DjLuxor · 02-27-2006, 12:23 PM

You keep talking about MAX pressure...well, your right...its the MAX pressure...but that doesnt mean its the safe pressure. Your Max body weight is probably 800 lbs...but its not safe, your bikes max speed...probably 185...still doesnt mean its safe...those are MAXIMUM notes.

not saying you are wrong but key in on the word DUAL-TOURING motorcycle applications.... we are talking SPORTBIKES am i right?

qbnito537 · 02-27-2006, 04:21 PM

No is the dunlop warranty for all motorcycle tires. Anyways that’s what Dunlop is expecting you do with their tires but the warranty is focus in tire longevity no rider longevity. (They recommend inflating to the max load pressure on the sidewall).
So....~41 psi (or what ever indicated) is safe for the tire but we can go down to ~31 ‘cause we want more traction in the oily streets of LV... right?

Mustang · 02-27-2006, 04:33 PM

Now your getting it

rodman · 02-27-2006, 05:06 PM

You guys are all wrong. Used to be there was kind of a generic PSI for street or racing tires. That's all out the window now-a-days. It completely depends on the tire manufacturer now. You wouldn't believe the variability of track tire PSI recommendations for the different tire brands, and even the different compounds/tires within a manufacturer. Get the facts from an official dealer of a particular tire. It's a whole new ball game today.

ok... then why does the pressure drop when you go to the track, with the same tires???? just curious. You guys do what you want and i will do what i do

STEEL · 02-27-2006, 05:52 PM

I'll try 33/34 and see how that handles.

DjLuxor · 02-28-2006, 03:58 PM
