Hi, strange thing happened over last few days...was gonna go out on my bike over the weekend, took it off the paddock stand and saw the rear tyre was flat,(only rode it 2 days beforehand)so put it back on the stand and pumped it up to 32psi.Checked it that evening and psi was 32psi still,checked it over next two days and still 32psi, went for a little ride around town and when I got back 35 psi.....(tyres have green stuff in for over a year now)....any ideas.?

there's your answer...........check your tyre and remove said item before it becomes a problem................oh and get a new tyre asap" />
Tubed? ...then that'll be Slime, an added self sealant, best check the tyre for damage, then replace the tube.
Tubeless?.......well that's just wrong, what sort of tyre damage could that be hiding

Pressure and temperature.
Hold on chaps, the mention of tyre sealant has led you down the wrong path, I think. The pressure went up by 3psi after a run around town.
Friction between tyre and road has heated the tyre air and made it expand, increasing the pressure.
The rise in pressure by a few degrees is expected. It is heat build up increasing the air pressure. That's why you check your tyre pressures "cold". The pressure will change as the ambient temperature changes. Recently my tyre pressures went up from one weekend to the next. The ambient temperature had gone up noticeably in recent days. You should check them before every ride and while you're at it a quick glance in case a screw was picked up the previous ride.
The advice by the other guys re sealant is sound in my book.
After checking it for punctures, check the valve isn't leaking. Had a new tyre which was fine for a few days then suddenly lost pressure due to a leaking valve.
Thanks to all replies...
Since the problem/deflation I have done a few trips 2 up and fully loaded and the tyre was fine. So bit of a strange one.... Thanks again....
