MOT and tyres

Featured Replies

My Fabia has got its first MOT next week, and its been a while since I've had a car MOT'ed so I'm wondering if the tyres will pass.

They have a little over 3 mm of tread over most of the tyre (its at least 1.5 - 2 mm above all the wear indicators, but the edges (outside mainly) are pretty much bald maybe 0.5 mm showing. They're Toyo Proxies T1R (?), and I seem to remember them not having much tread at the edges even when new.

So, the question is will they pass like that? Or, should I look into replacing the tyres before the MOT - they'll need doing within the next 1000 miles or so anyway.

Much thanks

Wear indicators are usually set above the legal minimum, but coming up to this time of year its really not worth running about on tyres that even you might think are suspect.

The inspection of the tyres is restricted to those fitted to the vehicle at the time of the test; this does not include any spare tyre/wheel.

The most obvious test requirement for tyres is of course that of wear' date=' the tyre must have at least 1.6mm of tread depth across the central three quarters and around the entire circumference. The other basic stipulation is that the tyres fitted across the same axle must be of the same size. This size ruling also extends to the aspect ratio of the tyre, for example, a tyre 175/70×14 must not be fitted on the same axle as a 175/65×14. One slight contradiction in this area is the use of the so called “standard‿ profile, these tyres may be marked, for example , 155×13 and have an aspect ratio of 82%, they can be fitted on the same axle as a tyre 155/80×13. This 2% difference is specifically allowed by the MoT test regulations.

When inspecting the tyres from underneath the tester will also examine each tyre for any lump or bulge which may indicate structural damage and also check that the tyres do not foul any part of the vehicle i.e. rubbing on bodywork or steering/suspension component. In the area of cuts the regulations state that any cut at least 25mm long or at least 10% of the tread width deep enough to reach the structure must fail. On the subject of structure, the tyre must not have any area of ply or cord exposed.

Another tyre feature which comes under the testers eye is that of rotation specific construction, these are easily spotted and will have a clear sidewall marking with either an arrow indicating forward direction of rotation or the word “outside‿ denoting outward facing fitment.

With tyre fitting in mind attention will be paid to the tyre valve ensuring that it is not damaged or seriously mis-aligned (often caused by poorly fitted wheel trims) and whether it is correctly seated on the wheel.

Moving onto the wheels, checks must be made by the tester to ensure that they are not badly damaged, distorted or cracked and in some cases where spoked wheels are fitted the spokes are not loose, bent or corroded. This reference to spokes applies equally to wire, steel and alloy construction.

Lastly, the tester will examine each road wheel for security, checking where possible for the correct number of nuts/studs/bolts. These checks must be done without disturbing any wheel trim/cap etc.

Sounds good to me as the central three quarters are okay. Point taken re 'suspect' tyres and the winter approaching. Like I say, they will be changed soon but I doubt I have time between now and the MOT.

Fingers crossed the rest of the car is good too :D

Good Luck :thumbup:

Good luck.

If we're hedging guesses, I reckon it will need a wishbone bush :P

Yeh, we can take guesses :D

I say drop links :o

IMO drop links is not a fail unless it has totally detached and it restricting the steering or interferring with the brakes

i wouldn't even say console bushes was a fail either unless the wishbone was hanging off completely, just pass and advise

Strange -last & this MOT -spare was looked at -I was led to understand ruling was -if carried -must be road legal

According to the ukmot website the spare wheel is not included in the MOT.

Woo! Passed :thumbup:

Not sure about advisories yet as I haven't collected it

Strange - got one advisory on thickness of front disks- tester got a shock when I told him that it was 20.5 mm ( haynes says new =22, replace = 19 ) - so do I complain /object etc .

No advisories for me :thumbup: but then again the garage knows better than that :rofl:

I wouldn't bother to do anything, the car passed with one advisory. Which (speaking with no experience of being an MOT tester) seems fair as the disc is about 2/3 worn and may need replacing before the next test :)

Lastly, the tester will examine each road wheel for security, checking where possible for the correct number of nuts/studs/bolts. These checks must be done without disturbing any wheel trim/cap etc.

So they check your wheel nuts without removing the plastic trim!

That's reassuring :eek:
