Tyre advice

Hey all, haven’t been on here for a long time (for various reasons, none forum related though)

I’ve picked up a screw in my rear tyre which I’m not sure will be repairable :unamused: question is though - it was serviced last month and the front tyres were 5.5mm, rears 6mm - will I get away with just changing the one with the screw in it, then once the others have worn down change all 4. I do on average less than 6k a year so they don’t get a huge amount of wear anyway.

Usually I change all 4 as they wear fairly evenly but in this scenario is seems a shame to bin any of them with the amount of tread left on them and no damage!

Depends where the screw is, inch from edge to middle usually repairable, too close to the sidewall & its new tyre safety wise, although can be repaired subject to the garage you use.

I’d, Get it repaired and replace all 4, when worn lower...

But you could change them now and sell if you can get some money back by selling them on?

Should have added a picture really, ideally I’d get it repaired if it can be. I don’t really fancy changing more than needed because of the tread left on them.

Unfortunately I don't think they can repair in that area! You could buy a part worn of the same make/size etc.

Yeah that was my thinking re repair.

Hmm I’d rather stick to new rather than part worn really, I’ve got Pilot Sport 4S all round.

With the rear being on 6mm and a new being 8mm it wouldn’t make a huge difference would it? Then next tyre change get all 4 done and hope I don’t pick up any other unwanted guests anywhere other than the middle!

Buy a pair (currently on offer at ATS) and either sell the good one you take off, or keep it in case you find yourself in the same situation again.

Like what Neil said get 2 new.
Put the new ones on the front and the current front ones on the back. Rear wears slower than the front so eventually they will be all even and then get 4.
These haldex awd are part time with no lsd or torsen diffs so wouldn’t really matter if one side had more tread than other and similarly no different between front and back as they are independent till the haldex kicks in whereas the old school Quattros had to be within 2 mm between left and right and front and back, well that’s what I was told by an Audi tech.

Might be different with AWD- not had one - but I would always put the new ones on ths rear.

Hey up James, yeah all good now mate. Hope you’re keeping well. Went down to the tyre place and as expected, not repairable. Said 1 will be fine due to the tread left, booked in for Wednesday. £160 all because of a f*****g screw

I would say that’s the norm as understeer is easier to handle than oversteer but OPs tyres are 5-6mm so pretty new and he’s intending to do all 4 eventually. If it had 2-3mm left I wouldn’t be doing that.
Exactly that, they’re literally just over a year old and probably done 6k if that. Decided to just change that one for now then when the others have worn down I’ll stick 4 new ones on.

It’s a pain. If it isn’t a screw it’s a ****** pothole that blows them up.
There’s load of new houses getting built where I am and in the last 5 years I’ve had 8 screws/nails in my tyres that’s more punctures than I’ve had in the 17 years of driving before that. Luckily had wheel and tyre insurance on the car so only cost me a tenner a time.
It’s the Lazy ****** workman at these sites and caught one of them sweeping the crap out the back of his van on to the pavement.

That seem a lot! What size wheels have you got? I just tried my old S3 reg and got:

You should always put new on the rear unless you want the back to overtake the front.

Doenst really apply if you are putting on like for like, which he pretty much is. I would agree if you were going for a pair of new tyres and you had like 4 or 3 mm left on the other pair.

Stick the new tyre on the front left. They typically wear more than any other wheel due to roundabouts.

"If you replace old tyres with new tyres and this does not apply to the whole set, there comes the question: Do you fit the new tyres at the front or back? Regardless of the drive type, we recommend not fitting the better tyres at the front, but always fitting them at the back. The reason is simple: The rear axle ensures the tracking stability of a vehicle."

" Another way to keep your tyre wear more even is to fit new tyres to the rear axle and move the older tyres to the front axle positions. This provides the best grip at the rear of the car where it’s needed, and you can get more from your tyres as they are worn more evenly, reducing the chance of replacement due to age alone."

"Mixing different tread depths is generally permissible. The tyre industry recommends fitting the new tyres onto the rear axle. This will provide greater grip to the rear axle and mitigate any potential oversteer condition or loss of vehicle stability on slippery surfaces."

Leave it to the experts​

A tyre specialist will tell you if your tyre can be repaired after damage has occurred and advise on correct fitment"

I’ve got 19’s, that’s £160 fitted - I usually go through Black Circles as they tend to be the cheapest, there was only £9 in it using them or the garage direct so just booked it with them.

What site is that you’ve posted the pic of?
Tyres on the drive.

Tyres on the drive.
All sorted now thankfully, although did have to go back the next day as the valve was a bit dodgy. Looked at the car that evening and the tyre was nearly flat again!

Took the cap off to pump it up and air was coming out, tapped the valve core and it stopped.

Had 235/35 ZR19 Michelin Pilot Super Sports fitted all round yesterday, Whilst I was sitting waiting for the tyres to be fitted saw this on a screen on repeat in the waiting room.

This is verbatim from the Continental website:

"Mixing tyres with different tread depths​

If you are replacing only two tyres on your vehicle, the new tyres will probably have a deeper tread depth than the older tyres.

Mixing different tread depths is generally permissible. The tyre industry recommends fitting the new tyres onto the rear axle. This will provide greater grip to the rear axle and mitigate any potential oversteer condition or loss of vehicle stability on slippery surfaces.

There can be exceptions, however. Some car manufacturers will recommend fitting the new tyres to the front axle, for example, if the car is a front-wheel drive. Consult your vehicle manufacturer’s handbook or a tyre specialist for further information."

There's a paragraph further down about cats and pigeons. It's just after the can of worms section.

For every argument there’s a counter.
main reasoning for putting new in back is under steer is easier to control than oversteer but then my argument will be the front does 90% of the braking so you would want the best tyres on front surely.
It’s definitely can of worms. Someone will come along and say something else completely different that also makes sense.
 
So it’s one of three

1) New rears to ensure the rear brakes work at maximum efficiency
2) New fronts to ensure you get a better feel and under steer is safer than oversteer
3) Make it rain at the tyre centre and do a ”Loadsamoney” (which is showing my age now) and put on fresh ones because you can

:wink:

In reality depends of the speed, it can be rears will brake 90%
Here somone bern wondering his rear brakes pads worn faster than fronts. I saw it like what no that's not right.
Then I replaced all pads and yeah rear pads were thinner
