High presure valve cap monitors

I don't think balance is going to be an issue. So many ricers run around with those "firefly" LED valve stem caps, and those things probably have some weight. I never heard any of my ricer friends complain about them screwing up their tires/wheels.

Yeah well my brother mounts the tires for them ricers and he tells me they cause some problems at really high speeds even with the little that they do weigh - bending valve stems and leaking air - he balances to a fraction of an ounce for the boys that want to go over 150mph. Car tires it should not matter so much because the weight of a car tire is much greater than a bike tire. I do wonder what size button cell they have inside them to make the LED lightup - probably runs down the battery pretty quick if they cool off at night, loose pressure and blink when no one is there.

Then it's a racket! You put these on and drive at high speeds, making the valve stems bend and leak air. Then the LED blinks and kills the battery!!

Yup the oil and battery companies are in it together. Remy had the same thing happen at Eveready in CT they did not want to make a rechargable Lithium battery that was safe and flexible. They want to keep making the throw away batteries.

Yep. I saw those a month or two back (and picked up two sets of the 40psi units). Unlike many of the places, the local NAPA really did have the 40psi caps that I wanted for my CRX and my wife's Civic (most stores only had 32 and 36psi units). And while they were slightly more per set than some of the units in the other stores, the NAPA units were in the correct psi for my needs, looked slightly lighter and smaller (less drag on the wheel), and also slightly better constructed than many of the units.

BTW: While 40psi might be low by the standards of this forum, it's actually pretty high by most car standards. However, I picked the 40psi caps (I actually often inflate to 42psi in practice), because it is still way above my car glove box plaque recommendations (32psi in the CRX, and only 28 in the Civic), while still being low enough that I'm both below the rating of the tires (44psi tires) and below the level where my wife complains about how the car drives (you have got to pay attention to the "wife acceptance factor" with some mods)...

NOTE: At least at the NAPA I go to, you can get a small discount if you are a AAA auto-club member, and show your AAA card during checkout. The discount isn't large, but (around here) it is slightly higher than the local sales tax, so it's a bit like getting the tax paid for by the discount. And every little bit helps! So if you are already a member of AAA (we are, mainly because the "emergency road service" is nice if/when one of our high mileage vehicles decides to have problems, often while we are commuting to/from work), you might as well ask if you can get a AAA discount.

I've had these valve caps for slightly over 3 months now, and am still impressed with them, I just switched from snow tires back to summer tires, so I checked tire presure on all of them with my digital gauge as I removed tires and valve caps, two tires were about 3psi low, and the caps don't start changing untill they get down to 46psi (4psi low), I've sence noticed that one of my summer tires has a slow leak (put in a tiny bit of slime and make sure it puddled over the nail hole) and so it's nice being able to tell at a glance if the tire really is low, or if the ground is uneven.
