Do you need to add air every week or so?

I have the t-valves from FOBO installed and I still have to put air in the tires about once a week.

Well, how much air do you have to add each time you check the tires? And does the front or rear seem to lose more than the other? I run an oem stone on the front, and run it at 41lbs. Seem to add maybe 1 or 2 lbs every 2 weeks. Got a darkside on the rear, and that General G-max , I run at 42, and it seems to be holding air as well as my front.

I rarely have to add air. You have a sleak.

Interesting...I installed these on my bike, and noted what I thought was a slight leak around the air valve. Prior to that, I could go a month before having to add a few pounds to each tire, but that was about it. I find the FOBO is really sensitive, especially to ambient temperatures. Not sure if it is the transmitters, or the way temperatures affect the tire pressures the way they do. I get about a four or five pound increase in pressures if the temperature is warm and I am on the highway.

I have noted my tire pressures showing a pound low, go to the gas station to buy some beer since it is football season, and drive home I note an increase of a pound + in my tire pressures. It isn't even a mile each way at 30 miles per hour, so I just leave them alone and fill up about once a month to the recommended pressures.

I have had a leak in 3 back tires / 2 rims and 2 front tires / 2 rims with 5 different valve stems then. The 4 original tires, rims, and valve stems and the 2 t-valve replacements. I bought silver rims as take offs from Honda of Russelville and the original new bike tires and rims. That sounds highly unlikely that all of these parts could be bad.

If you have added Fobo T-Stem(s)... you have had to most certainly break down the tire bead(s) to do so.

In doing so, sometimes it does take a while for the tire to completely seal back onto the rim. It happened to me as well when I installed my front T-Stem recently. I have seen this with new tires mounted as well.

Check the Fobo T-stem with soapy water (mine does not bubble, even ever so slightly). Check the air pressure frequently (daily at the same ambient temperature) and ride the bike. More likely than not... the slight loss of air will eventually cease. It did for me

Also take into account that lower ambient air temperature will result in a decrease of your tire pressure. Making you think you may have a leak.

I had the FOBO t-valves installed by the dealer.

I check pressure before every ride. Unless I've picked up a nail or something in the tire, it doesn't vary all that much at all.
IF you're adding air every week, I'd suggest getting some soapy water and start looking for a leak, especially around the valve stems.

I do a pre trip before every ride. I never have to add air...

I use the FOBO T-Valves with Garmin TPMS caps.

I find that I lose almost exactly 1.0psi per week. I have ALSO found that (at least in terms of the Garmin system...and therefore I presume the others as well, as the systems are pretty much the same throughout the industry) the pressure readout can vary a bit from hour to hour and day to day...indicating that the system doesn't always read EXACTLY the same each and every time. The variance can be as much as 0.6-0.7psi.

When I first installed the system, I chased the pressure a bit...but found, if I had a low reading, that quite often if I let the bike sit and waited a few hours it would read closer to the expected values. This may be due to changes in ambient air temp or perhaps changes in ambient air pressure.

Either way, I eventually DO need to trot out the compressor every 7-10 days to bring it back up to running pressures. This has annoyed me as well, as all of my past bikes (eleven in total..ranging from Yamaha's to Triumphs to Matchless to Katanas ) all have held pressures for several months or more.

Speaking of alarms. The Garmin system doesn't ping your phone, but can be set to any threshold you choose and will alarm on your GPS unit.
