A320 tyre pressure indication
 

I've just done 2 sectors as pax on an A320. The 1st was an hour late in arriving and judging by the reception team on 4 engineers ,a jack and a spare nose tyre, coupled with a number of canvass spots on the arriving gear would indicate a prior knowledge.

On my old steam B747s the only indication of a tyre problem was vibration.Does the A320 have tyre pressure indications in the flightdeck?
I certainly would have appreciated that over the years on the classic B747.

The A320 has tyre pressure indications on the wheel system display page on the lower ECAM screen but only for the main wheels. Problems with the nose wheel tyre pressures would become apparent by vibration as you say or perhaps "pulling" to the left or right during taxying.

Sounds like the nose wheel worn beyond limits and the crew still took the aircraft home. Still, saved a few pennies for the airline. A few times I've had captains inform me on arrival that one of the tyres is worn beyond limits. Really? You can see that from the flight deck?
One wheel change and one ASR for me to fill out!

Well if both wheels were shagged and they only changed one it will now vibrate and shimmy like hell!! Lol

Wunwing, eagle vision to spy "a number of canvass spots" from the pax cabin! I hope the Engineers brought out a nose wheel assy, they would have needed a big set of tyre levers to change a tyre! Tyre wear is normally inspected daily, along with the normal "Walkround" by the operating flight crew. :ok:

Tyre Pressure Indication System (TPIS) is the computer that generates the error signals to Flight Warning Computers (FWC) for ECAM displays. Once the aircraft is powered up and the Wheel page is brought, all errors will be on spotlight.

during landing A320, automatically brings the Wheel page and there anything wrong will be also shown and chims go ring!, but I haven't come across any in flight pressure reduction of a wheel, but yet possible?

Fly3 . . A320 wheel pressure is displayed on ECAM for every wheel! . . all 6 wheels including the front 2. The front wheel tyre pressure is very important as it is the nose wheel that holds the centre line with the rudder until u slow down :)

I suspect this is an optional feature. Our A319/20s don't display it.

What is normal tyre pressure? Any limitations on it?
I barely see any info about it in the FCOM.
Don't mean to hijack the thread. :O

Tyre pressure is a serious issue....

Be sure yours are inflated properly.

Was wondering what everyone was talking about, indeed it is a company option. apparently a pain to maintain.

WhySoTough the tire pressure is a function of your weight and tire dimensions!

For A320

AMM says:

71.9 / 73.9 / 75.9 ton MRW with following tire dimensions
46 X 17 R20 -> 193psi
46 X 16 20 -> 193psi
49 X 17 20 -> 160psi
49 X 19 20 -> 144psi

77.4 ton MRW with following tire dimensions
46 X 16 20 -> 200psi
46 X 17 R20-> 200psi
49 X 17 20 -> 167psi
49 X 19 20 -> 149psi

And about the TPIS on A320s yes its an option! I lately found out! Sorry I thought its standard!

And temperature......

yotty.

Actually I saw the aircraft arrive from a terminal window looking down onto the nose of the aircraft.

Clearly as the engineers arrived with a jack and spare wheel 45 minutes prior to arrival, they knew about the problem quite early.
It was not my intention to criticise the crew, this is not the right board for that. It just spiked my interest to see if things had improved since my retirement.

Blown tyres interest me after I had one throw a tread on a B747SP during take off and take out a large section of the rear end and hydraulic lines.

Monitoring tyre pressures would probably have prevented that one.
