Pumping up my tyres and saw this . It's probably 5mm deep
Lol yes
I would say so.
Not as bad as my mum calling to say she has a "puncture" 😳
Mine's passed its MOT at 2 separate garages for a few years with similar though possibly not quite as deep as yours. Can you see anything other than rubber?
Just rubber. Had a similar thing years back , took it to the tyre shop and they said it was ok.
Superglue and carry on
Any cords showing? If not glue it be fine
I had one very slightly worse than that last week. The tyre shop, which is one I trust, said to replace it.
It’s probably fine, but replace for peace of mind. Would prob help sweeten the pill if it’s over half worn anyway!
Personally I'd replace it.
No wires and no bulges safe to glue and carry on.
As Duncan says, if there are no cords visible, it's legal and considered roadworthy.
But when they say no cords visible, they mean get a blunt screwdriver and have a proper look.
I'm not sure of the max surface area but I think 25mm or 10% of the width is normally the max for cuts, not sure if this is just tread damage or also sidewall.
Any bulges or ripples on the inner or outer sidewall and it's unroadworthy.
Judging by all the other marks around the area, I would say thats clouted a kerb, or simialr pretty hard.
With the visible damage, internal invisible damage has probably been caused to the carcass.
I'd change it.
Better than:
Blow out and the results of same,
'Discussion' with plod at the side of the road, on a journey, and then having to change the wheel whilst they watched, and then diverting to Kwik Fit*
There are other fast fit tyre depots.
The fact you've been on here and asked means it would be prudent to ignore the machismos and change it.
Avoiding the scenario where it blows out and injures or worse friends or family members and the evidence that you sort of knew it was possibly unsafe.
As above, I'd be changing it. An 18 year old and broke version of myself would have glued it, but for the cost is it worth the risk?
It's going in this afternoon.
New tyre is £69.50 fitted.
My fatty tyres cost £90 each.
Silly not to.
Initially I wasn't concerned till I zoomed in and noticed that's a reasonably sized hex key for scale.
That's a biiiiig gouge.
