Check your tire gauge

Had an interesting revelation yesterday at the track. Set my tires with my guage and go out for first session. Check off track and back on warmers, still good.

Checked them after third session with the ambient temps up and sun out, my friends pressure guage was close by so used it. Showed 5 psi more tha earlier.........YIKES. Go grab my guage, shows what i though was "appropriate psi," and 5 pounds different than friends.

Scrtach my head, take them both to John H. and he checks them both against his calibrator. Long and short my friends was within 0.5 lbs and mine was off 4.5 lbs!!!! He then comes and looks at my tires, hardly any wear b/c of the improper psi.

Use my friends to set the proper psi now, and magically...........knocked off 3 seconds off my lap times in the last 3 sessions, and now tire actually looks like its "being worked."


Lucky for me i'm slow otherwise i might have put myself on my head already. Stupid me, live and learn. So...................be sure you have a quality guage (thought i did) and/or get it checked out.

I carry gauges that are calibrated within +/- .05% if anyone would like to get one. just send me a PM

I bought one at cycle gear just to see how close it was. Took it back to the lab and it was 3 psi off.

3 psi is HUGE on the track.

or is it just buy a few take them somewhere and find out which one are properly calibrated?

Most of the best high dollar gauges are sold for auto racing, very few gear sales towards bikes. That's a good place to begin your search for one.

I use a digital gauge I got from a mechanic friend of mine years ago- still accurate after 3 or so years of use.

My teammate on the other hand, uses one of those old style everyone's dad used to carry in the glove box- you know, the ones that look like a silver pen? The gauge is pushed out by the pressure to give you a reading. Anyway, his $5 gauge is accurate to .5lb and has been for the past 2 years.

Mine cost $40... I don't know what they retail for, but I'll get the brand name off it.

I carry a liquid filled gauge for $60. They are made by Intercomp for a independent distributor. I've had mine for almost 2 years and it is still within 1/2 pound.

hope that's not the same gauge you use for the rear slicks on the drag car. Loose 4.5 lbs and the rims would be on the ground

Dont bet your life on it. The guages we use for the racecar is a 5 inch low pressure tire guage that dosnt even read above 15 psi, and for flowing the nitrous sytems is the same and both are kept in seprate sealed sealed with with foam padding cut for each gauge

Good thing you weren't cookin out there or it could've been bad!! I bought mine fom Jegs for around 35.00, it has the pressure release valve and all that...
On a side note, its kinda relative, the dealer around me...wont say names....a couple of monthsback, I took my bike on for service, the mechanice "adjusted" my tire pressure in case I "really want to haul " to 40psi front and back!!!!!! Can you believe that!!! Anywayz, good post!
