Whilst sitting in a traffic jam in Edinburgh today , I noticed something strange on the bus wheel next to me. It had some sort of anologue counter thingy in the middle of the wheel and the actual unit did not rotate with the wheel.
What would this be for? It could well be that every bus has one of these, its just I don't normally pay attention to them!

Engine serviced on hours running, chassis/running gear on miles covered?

No, they're not fitted to all of them. Some of the minibuses round here (Mercedez-Benz chassis) used to have them but I've noticed a lot now have blanking plates where they used to be.

to see how many miles the bus has covered for wear on tyres?
just in case those pesky bus drivers are wheel spinning them to show off?
bling!

Seen on buses in London as well. Somebody in another thread mentioned leased tyres.

Surely that's what an odometer and a depth gauge are for?
It's a good question and I've often wondered it myself.

It's called a hub odometer

They're used to keep track of the miles travelled by a set of tyres as often on commercial vehicles the tyres are leased rather than purchased

Its a milege counter, every bus should have them, instead of having speedo counter on the dash' they record it on the rear hub of the wheel maybe because its more accurate that way.

knew i was right ;-P
what a guess ;-)

My apologise VTiredeyes, you should never trust a speedo in that case!
I've noticed that some, at least, of the Stagecoach buses around here seem to have been fitted with LCD odometers. Would this be a factory fit? I doubt 'cos I've seen them on at least an N-reg. I've also noticed that broken tachos have stripes a black insulation tape put across them to cover them up. Definately very few with hub odometers though.

Going back 30yrs or so they were usually fitted on trailers / semi trailers. A trailer might be used every day, or stuck in the back of the depot for weeks on end. There was no other way of telling when a trailer was due for servicing.

It's far from uncommon for buses that do not have to have a tachometer fitted to have a non functioning speedometer/odometer. They cost money to mentain. The hub mounted item as mentioned earlier provides an alternative, often for leased tyred etc.
I dare say I've driven mose buses with faulty speedos than accurate ones.

I think Arriva buses round here do the same 2 Cymrog, some ive noticed have a sticker over the top saying 'tacho not valid'.

Where I work they become due for servicing the day the ministry stop them :-(

I always thought that hubodometers were a tamper-proof way of showing actual mileage travelled. Here in New Zealand, diesel vehicles have to pay for mileage used, as this is not built into the fuel cost. If you are stopped by police, they will check the mileage against your 'ticket' displayed on the windscreen. It's best if you have paid for it before you use it.
