tire pressure

hi i was wondering what is the normal tire pressure suppose to be for a normal sport bike just for cruising not for wheelies and stuff. thnx

recomended pressures should be on your bike or in your manual. they are a starting point to further tuning using the 10/20 method.

Check the book... for reference though, my SV says 33 front 36 rear.

:scratch: 10/20?...alright, I'm an idiot. Please explain.

Manual and it might be stamped on that plate on your frame. Mine is. My recommended pressure is 33 front and 36 rear. I run about 31 and 33 respectively with tremendous grip. Higher wear.

I'm supposed to be at 32/36 and I'm currently running 30/34 for just a little more grip...

I run 36 and 40 on my 208's

34/36 for my Powers. i believe that's recommended for my bike. What the hell is the 10/20 method?

Personally 32/34 on BT014's. Also alot depends on temperature. Do a cold psi test. Ride then check the psi after the tires are warm. Make adjustments from there.:luck:

Most tire spec's on the tires say Max pressure cold???

Always set 'em cold...old school bias ply philosophy that I am comfortable with and still use. Figure out how you want to measure them and be consistent. Check them often!

Manufacturer recommendations are a good baseline but you have to factor in what kinda riding your doing...I'm 30f-29r at track days and 36f-39r for commuting. Cold day and mountain scratching? 32-32. Warm summer day 34-37...

Remember pressure builds with heat...

Always set tire pressures "cold"; ie ambient air temp. The purpose is to be able to baseline your temps. Boyle's Law, Charle's Law, and the State of Pressure show that as tire temps increase, so does pressure. Taking a pressure reading at 630 in the morning, your gauge may read 32psi. Hop off the bike at noon, after riding 150 miles of backroads, and your gauge may read 47psi. Go grab a Big Mac, take a rest stop and drink a soda....come back and recheck in 45 minutes, and your tire pressure will be back down to 32psi because the tire is cooler, now.

There's a reason why he has over 100 rep points.

10/20 method: Basically on the street you want the psi to increase 10% in the front and 20% in the rear under your usual riding conditions. Start with your recomended psi. ride a good ride. check your psi. If its less than the proper percent (tires' arent getting warm enough) then lower the pressure, if its more (tires' are too hot) then raise the pressure. I check mine once a week to keep them in spec. I ride everyday so i get alot of heat cycles and my tires get harder faster. So i use this to keep things right. And its different for everyone. Bike, setup, rider weight, tire brand, wear on tires, seasons, and riding style all contribute to different pressures needing to be used for different people.

the 10/20 method is the reason on my 9R I rode like 3# under the Kaw suggest pressures... I always rode either too hard or too fast and long on the highway for the higher pressure.

Check your owners manual and go from there.... adjust a few times and see what you like. More than likely you will go down in press and not up.

And remember...less air is going to wear your tires faster. If you care about that type of thing.

thanks for the explanation on the 10/20 thing. I don't pay near enough attention to my tires..i know, bad thing:disapp:
