Title: Cause for concern?
Post by: zpyder on May 17, 2013, 09:08:31 AM
I think when I hit a curb getting out of the way of an emergency vehicle, or maybe hit a pothole, I must have done this. It's only gone through the edge of the tire where a bit curves out, presumably to protect the alloys from scrapes, so I am assuming it shouldn't cause the tire to blow out or anything? Thoughts?

Tear just by the "e4" if you can't see it.

I think that could quickly turn into a problem - the sidewall is just as important as the tread, I've never had a blow out and don't fancy one so personally I'd replace it (I don't think they can repair tears like that). £50 for a tyre or your personal safety, I know which I would choose :)

If it eggs, it can cause a blowout.  I'd get that changed.

I assume "eggs" means swells? Or cracks?

Just so I'm clear, the tear doesn't run into the tyre, more towards the axle, more of a slice than a tear. If I pulled it I could take a chunk of the tyre out etc. I guess I'll see a tyre place tomorrow.

I suspect it'll be more like £75 than £50 to replace :(

Can you pull it apart, is it cut down to any cords?

Personally id leave it but keep an eye on it, if it starts to bulge replace it.

Do you have a spare in the car ? if you want to be cheap, swap them :)

Sidewall damage = replacement basically. It's the part of the tyre most stressed and could go at any moment.

I also wouldn't be surprised if that's a slow puncture.

Been like that for 2+ weeks with no tyre pressure change.

Also driven on it about 200 miles probably. Including lots of speed bumps and gravel/farm track roads.

I get the impression consensus is to change the tyre.

I don't know what's happened. When I had the micra, in 8 years only 2 tyres needed changing due to wear. In the last 4 years in the Mazda 3 and Mazda 2, I've had to replace 2 tyres due to damage plus probably about 6 plugs.

Low profile tyres? Dodgy compressor gauge meaning you're under filling them?

Even if the compressor gauge wasn't 100% accurate, it'd at least show if the pressure was going down?

Even when the below happened, the pressure only dropped 10psi over a week.

Tempted to start keeping my old tyres, would make some good planters for in the garden etc.

Probably on the cusp of greater than 25mm, though I don't think you can see any ply or cord etc

Id not bother to replace it then that being the case.. but my tyres cost approx. £250 a corner so id be even less inclined to replace them if they didn't absolutely need it.

what size tyres are they ?

check online before you go to a tyre place so you know roughly how much they should cost ;)
Title: Re: Cause for concern?

Doing a reg check to check on the correct tyres I'll be paying between £55 (budget)  to £130 (premium).

Back from the tyre place. They said it should be ok as the tear only goes through the rim protector on the tyre. No sign of cords etc, just need to keep an eye on it.  They weren't concerned though, and usually I've had the feeling they'll take any excuse to make some money.

That's good news, as long as you keep an eye on it hopefully it will last until both the pair are due for a change anyway.

good news indeed, if a tyre salesman tells you that you don't need a new tyre, you can probably be fairly confident it's ok

thats good - if there was any concern, I think they are under legal obligation not to allow you drive your car!

What I thought as it was so near rim but I did not dare say it was ok without a close look.

Just be glad it is not on run-flats.

Managed to get some steel rope right through the tyre:

255/30 19z runflats, got a choice of Bridgestone Potenza RE050 or Pirelli P-Zero Rosso both at a wallet-crippling £320 per tyre :D Killer is had only replaced it at Christmas and still had over 6mm on it.

So....the benefit of run-on-flats, is that you can still drive on them even with a puncture, but I assume only till you can repair/replace them?

For the inconvenience of changing to the spare tyre, I think I'd stick with normal ones!

i think youre allowed 50mph on them. to get you to the nearest tyre shop.

ive got them on my 330d. they're 17s, expensive, they tramline for fun and they lose air/help you crack your alloys.

but im not plannning on changing them, cos there is a plentiful supply of them cheap on ebay, when people sell them on.
