you must have got a delayed prohibition .......... comes intoforce in say 1hrs time, to give you chance to get somewhere, then vehicle has to be moted before it can be used again VOSA can put it off the road on the spot and you have to get it towed to be repaired. They have prob requested that it has a full test to clear the pg9 because they where unable to accertain the condition of the rest of the vehicle at the roadside

'Delayed' for 7 or 14 days, shirley? Produce the new MoT plus the PG9 "delayed prohibition notice" within that period and it is sorted.

Sounds like the driver was very lucky with that tyre - lucky he didn't come a cropper on a wet road smile .

How are you going to prove the tyre you've had tested was the same one that VOSA tested at the roadside?

Unless VOSA put some hidden marker on it, they'll just say it's a different tyre, or that it's almost illegal anyway and the driver would not have gotten home on it.
easy, he wrote the serial number of the tyre down, we still have the old tyre with matching serial number to his docs, not that hard to proove its the same tyre.

0.03 mm above the limit is low, but its still above the limit.

will find out some more tomorow. either way like i said im still middle man here, i fully agree with vosa being out and about, same as the dvla(even though they are complete bds who almost cost me £25 after they lost my V5 which has now turned up 4 months after sending it off)

So you'd be chamging it tomorrow anyway?
Anything less tham 2mm is asking for trouble... not from police etc more from a grip point of view... The limit is too low in my eyes.

Any how hope you get it sorted.

I know a lot of the tyre manufacturers and tyre fitters want the limit changed to 3mm 'for safety' as 1.6mm doesn't get rid of the water enough in wet conditions.

Soon they'll be asking for a 6mm minimum or requiring a different set of tyres for each weather condition 'for safety'.

Can you actually get a gauge that measures that accurately?!

I would have thought the dirt on the average tyre is thicker than that, but there you go.

In answer to your question, I have no idea. In a lab, presumably ?

Well obviously that can be meaured - but I very much doubt a garage has the sort of precision kit to do this.

Would be interesting to see it go to court and the outcome.

Yep, that's real specialist equipment.
Most garages will have calipers, micrometers and DTIs.

ok so i have the pace form and prohabition form infront of me.
pace from, havnt ticked alot of the boxes and filled out bits of it, they havnt written down the purpose of the stop on the form, wether anything was found, half a post code, or filled out the back off it where it says this vehicle XXXXX has been searched and stopped blah blah blah.

now the vosa one, really does ask the question wether the vosa operator is fit to do his job in my personal opinion. he has printed it on headed paper upside down, recorded the tyre size wrong, and got the tyre tread depth completly wrong, aswell as not recording the depths he recorded that would make it illegal on the prohibition form.

The problem is 0.03mm is so small that just putting the measuring device into the tread/groove could deform it enough to introduce this difference.

If the limit is 1.6mm then 1.63mm is so close to being illegal that it's not worth arguing.

So what? How often are we told that 30mph is the limit, so doing 31 is breaking the law? The tyre was legal.

Zero the calipers on the "flat" surface of the tyre and most of the error will be eliminated.
30 microns is very small though, I agree. About the thickness of a green Rizla+ cigarette paper, in case anybody wanted to put it into context.
Cheap office photocopying paper is about 0.09-0.10mm thick.

I personally would never let my tyres get that close to the limit. Once they get below 3mm performance in standing water gets very bad very quickly.

left in a distinctvly sign written van, yeh sounds real likely.
and had the tire tested now, report 1.63mm all around apart from 2 spots on the edge where its 1.39mm....now correct me if im wrong, but the tyre must 1.6mm over the central 3/4 of the tyre. making that tyre legal.
we have to go and pay for a new mot tomorow, the previous is only 3 months old!
then a fair drive down to cardiff to get the prohabition taken off it, then send a letter off then to get the van back on the road for 0.2mm in 2 very tiny spots!
why moan as surely you would of been fitting a new tyre before it went to cardiff anyway ????

What I meant (and I'm on your side) is they VOSA operator might have even used the same tool, but exerted slightly less pressure on it, therefore giving him a reading of less than 1.6mm (e.g. 1.57mm). So they'd just say you measured it wrong.

The difference between his measurement and yours is minute (i.e. thickness of a fag paper) and there's no way you could prove to the operator that your measurement makes it legal when his doesn't - the phrase "I am the law!" comes to mind.
There is so little difference that a visual check would show the wear indicators were at the same level as the rest of the tread. At that level there's no way someone - it's the driver's responsibility to check the tyres were legal before he drove the vehicle - would be able to honestly say "I checked them 10 minutes ago and they were well above the wear indicator guv.".
