Runflat Indicator

[JayT]

My Runflat Indicator came on (red light) last night but on inspecting the tyres they all seemed ok. So I checked the tyre pressures this afternoon and they were all ok. Only the right rear was slightly down.. 2.4 bar instead on 2.5 bar. Would this slight decrease activate the system or could it be that it was just malfunctioning?

I've reset the system but I'm worried that I may actually have a flat.

Any advice??

Thanks
Jay

As long as your tires are properly holding pressure, then you do not have a flat. I have had the indicator come on with only a slight difference in pressure in the past. If I were you, I would just reset the indicator and keep a close check on tire pressure for the next few days.

+1 has happened before. Keeps you on the edge of your seat!

I had the yellow light come on-thought to myself I was going to have to replace those darn OEMs before I was ready. Drove a little slower than normal to the local service station and checked the pressures. They were all well *above* pressure. I had adjusted pressures several weeks ago and the temps have gone up since then --straight from winter to summer, whew. Rears were reading 42 instead of 36, fronts were both at least 6 over. Let some air out, reset the monitor and no problems since. Scared the c#@$ out of me though.

Consider using nitrogen to pressurize your tires. Ambient air temperature will have much less effect on tire pressure and therefore less opportunity for your tire pressure monitor to indicate low tire pressure. In addition tire performance is significantly improved.

How do you reset the indicator, mine came on this afternoon, yet tyres appear OK.

The only reason "nitrogen" works is it's dry. In general, at the speeds we drive, it's of no consequence other than making money for the service station or tire fitter than sells it to you. I've had it in tires before, only when I've bought tires and it's a "free fill". "Regular old" air is 78% nitrogen.
