Tyre wear - inside

A definite fail on the "visible tread pattern" test, ergo instant fail regardless of tread depth on the rest.

Really, can you explain?

There appears to be visible tread across 75% of that tyre.

I would say the wheel allignment is worth it for that price, as long as it's done correctly. It's the type of thing that pays off more than tyre wear. The fuel efficiency benefit would be minimal, but it is a benefit none the less. Improved grip and handling as well as possibility of over 50% longer life on the tyre.

I'd phone some other places though for quotes. I hear the Hunter 4 wheel allignment system that some garages use is the best to look for. Usually £100ish

I agree. There's a load of BS in this thread. The central 75% has more than 1.6mm, the baldy edge doesn't come into it. I have no idea what AdrianC is on about either but that goes for most his posts.

I vote fail, using the comparison photo the left hand grooves are within the centre 75%, op's photo is taken at an angle (it makes the centre smooth portion look off centre) making measurement impossible. I think the confusion is over 75% or central 75%, which is the measurement used in the MOT manual

I've seen part-worns form sale that look worse than that! Take it somewhere else for a test next year as the MoT tester seems very picky to have failed you; an advisory would have done.

Phoned another place, £100 + Vat, and as I've ordered the tyres already I'll let them do it in one go I suppose.

Did some Googling, they reckon if you drive like a c**t, sorry 'corner enthusiastically,' then the tyres will wear evenly given the typical config on my Eos (with GTI engine). If you are more gentle, then you get what is seen in my pic, and in that case you can adjust it.

Agreed that the tread has to be checked over the central 75% (ie: equal around the centre line of the tyre). But there's also the information note to S.4.1 which states categorically:

Grooves that had not been cut as deep as those containing the wear indicators when new are not to be considered as part of the tread pattern.

It's common for the sipes on modern tyres' shoulders to be shallower than the main tread grooves, and the photo of the new Bridgestone posted earlier suggests that's the case with these tyres.

In fact, a larger version here shows quite clearly that the other shoulder is cut shallower than the main grooves. If you look around where the bar of wear indicators are, there's a definite step down from the end of the sipes into the longitudinal groove. Note that the manual doesn't specify "how much" shallower, so shallower is shallower.

In which case they're not considered part of the tread pattern and it doesn't matter whether they're still there or not in a legal sense. Road safety, especially in current conditions, is another matter of course!

The tyres are definitely showing uneven wear, even despite the shallower shoulder, but they are legal.

In the end however the choice of £50 for a new MOT and then new tyres in a few weeks, or £216 for two new tyres now is a no-brainer.

But I won't be going back there again!

You never did confirm if these were runflats or not.

In my experience runflats are very sensitive to wrong pressure.

Make sure you have it right!

As I said in an earlier reply I would be fitting Contis as I've found the Bridgestones to be too soft for me.
