Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

Assuming no track work, what mileage are people getting out of their tyres? I have no idea what to expect - I'm guessing around 10,000, but haven't a clue. I put new tyres on mine when I bought it, so I'm curious.

POST 2Original post

When I bought mine it had nearly new tyres all round (so perhaps 6mm). MOT yesterday and no comment was made so maybe 3mm. 3 years and 9000 miles

POST 3Original post

On my 3rd set of Michelin rears in 21k , 2 sets of fronts. 991.2 carrera 4 gts

POST 4Original post

I would replace my tyres at 3mm or 3 years whichever comes first. Fronts especially, as they do the most crucial work.

POST 5 / ORIGINAL POSTEROriginal post

Useful info thanks.... it's sounding like around 7,000 miles and then a proper check.

POST 6Original post

I would say check before the 7K, I would measure the inner + outer edges and the middle and then do it again after a couple of thousand miles. I've just replaced my two three year old rears on 991.2 GTS and the inside of one tyre was worn down to the cords. The other rear was significantly more worn on the inside compared to the middle and outer edge. No idea how many miles it had done on those tyres as I bought the car in Aug 25. I had a geo carried out on the car at the cost of £200 to ensure it was setup propertly too.

POST 7 / ORIGINAL POSTEROriginal post

Good advice. Someone (was it you?) posted pics of their worn down to cords tyres recently which prompted my question.

POST 8Original post

It’s probably worth noting that a .2 will have lots more torque than a .1

POST 9 / ORIGINAL POSTEROriginal post

LastPoster said: It s probably worth noting that a .2 will have lots more torque than a .1 Yep, I think it's 44lb-ft more than my C4S thanks to Mr Turbo. Even so, the advice to check tyres a bit earlier than I had originally thought is very helpful.

POST 10Original post

I’ve just had 2 rears replaced , I started getting vibration through the whole car at 98 +. Once the car was on a ramp , you could see there was 4mm on the middle but the inner edges were both bald ! New tyres, car is silky smooth again .

Even so, the advice to check tyres a bit earlier than I had originally thought is very helpful. Yes, that was my point really. My wear over 8000 miles in three years (my 9000 above was terrible maths induced) in a .1 might well have been more wear in a .2 doing roughly the same use.

NDA said: Good advice. Someone (was it you?) posted pics of their worn down to cords tyres recently which prompted my question. Possibly it was me but I don't post a lot of images as it's pain compared to 911uk.
