Tire Pressure Database
So this morning I was late for work, jumped on and rode. At the first corner I knew I was down by 5-8 psi. Front was heavy and it dipped pretty low. It was also 3 degrees (Celsius) and the last time I set them was at around 20 degrees. I normally check them twice a week, but its been raining for the last couple days and I figured that it wouldn't make a difference. Which is the best way to end up crashing your bike, Always check your pressures.
I find the stock setting a little to "heavy" in the front and rear to "stiff", therefore I keep them at 32 front and 30 rear. So now that the pressure's are where they're supposed to be, I got to thinking: why don't we have a Tire Pressure Database? With all the members here, living in all parts of the world, with different tires and setup, it would be neat and helpful to get an idea what people are riding on. I think it should go like this: Tires (F/R): Pirelli Diablo Rosso II (both) Tire Size(F/R): stock/140 Pressures (F/R): 32/30 psi Rider Weight: 210 lbs Suspension Mods/Preload settings: none/3rd "notch" (rear) Average temps/location: 5-20 degrees Celsius / Toronto Riding type: Daily driver/commuter Other Info: I find front end more stable with an extra two pounds. This should help members get an idea of what settings to try for their setup, it should be useful to newcomers too, and keep people thinking about their tire pressures. |

I like your idea.
Experimentation is better than blindly using the manual's recommendation. In hot Florida, I have found the best combination in keeping 28 psi for a front Avon and 30 psi for a Kenda rear. Tires (F/R): Avon AM63 Viper / Kenda 671 Tire Size(F/R): 100/80-16 / 130/90-16 Pressures (F/R): 28/30 psi Rider Weight: 185 lbs Suspension Mods/Preload settings: none/none (pre-gen) Average temps/location: 80 - 90 degrees Celsius (27 - 32 F) / South Florida Riding type: Daily driver/commuter Other Info: Excellent performance in rain

How can you get precise readings? .........I mean, what instrument do you use or recommend?
I cannot find any gauge able to do so. Also, each measurement introduces a little reduction of pressure, especially in the smaller front tire.

Found the email. This is an Australian distributer of longacre.
" Hi Brad The full Longacre range of gauges are among the best in the world. We don't have a tolerance but we do supply these to Supercar teams and if they miss the mark by half a Ib there race is done. All of the Longacre gauges are vented unlike a lot that are out there on the market, this stops pressure build up with temp changes which is what throws gauges out Kind Regards, Steve Castles GMP Racing Products Pty Ltd. 20B Clifford St Huntingdale VIC 3166 Australia TEL:+61 3 9543 6222 FAX: +61 3 95436244 www.gmpracingproducts.com.au email@gmpracingproducts.com.au FaceBook us here " It looks like they have all the tolerances on the page now. The 0.5 P.S.I accuracy was for a reasonably price gauge. If you want to spend 300 you can get something accurate to 0.1 P.S.I.. They have every type of gauge you can think of. |

When I use the digital gauges, I slightly overfill the tire (by a PSI or 2), then use the gauge to let out the extra air a tiny bit at a time by not seating if fully on the valve stem. Let a little out, seat fully, let a little out seat fully, until I get the desired pressure I want This is the one I like to use the most Slime Digital Pressure Gauge Model 20074. I bought one 3 years ago and liked it. It worked flawlessly. I keep it in the tank bag. After a little over 3 years the unit started to display a digital code. Found out the battery could not be replaced. Contacted Slime and told them about it and they sent a free replacement. I haven't seen one in the for a while. 0-160 max PSI It reads in Bar,Kg/cm2, KPa, and PSI. You can toggle thru them all. Has a feature to clear the last reading. I have 2 digital, one stick/pencil type and one analog tire pressure gauge and they are all .50-1 psi within each other. (IMHO not a big deal unless you are racing) Here's a good article on tire pressure gauges and accuracy. http://www.mcnews.com/mcn/technical/200511gauges.pdf |

Model: 2004
Tire: Pirelli MT75 F/R Pressure:32 Front 34.5 Rear Suspension mods:new gen shock 2 clicks preload (need to try 3) Riding conditions:spirited back road riding/occasional commuter. Rider: 130lbs without gear Comments: so far I have had nothing to question about these tires they have never once surprised me very predictable. After I bumped up the tire 1.5 psi f/r the bike steered quicker and changed direction better. |
