Tyre Life Anyone ever seen this happen before?

323GT-R · 24th March 2007, 16:45

Here's a pic of the inside of my front tyres. These are the 225/40/18s that were supplied on the car from new.

This has happened to both front tyres on the inside of both shoulders, it looks like the layers of the tyre have seperated in this area, which eventually led to one of them blowing out on the motorway last night. The sidewall / shoulder of the tyre had lost all strength, and you could visibly see the one intact tyre was distroted all round the outside of both sides. I had no choice but to get them both replaced immediately. Both front tyres are now back at my dealer, supposedly they have to send them back to the manufacturer for analysis. What worries me is that if it's a batch problem, I still have two of them on the back of the car... The car was serviced 2000 miles ago, tyre pressures have always been as per honda recomendations. There were no visible signs of the problem, until I noticed a slight vibration through the steering driving home on Thursday, which progressively got worse on friday.

323,

Do you regularly drive (possibly quickly) over those one meter wide speed humps - the ones where if you take them centrally you tyres just brush the edges and you don't get much of a bump?

Or possibly a mini roundabout that you clip?

Those speed humps (cushions) can cause this sidewall damage, it's most likely to be the cause if it's the inside sidewalls of the front tyres.

stewright · 24th March 2007, 23:29

Pottsy .. what's the best way to drive over humps like that then?

ste

Pottsy · 24th March 2007, 23:32

Slowly!

One wheel over the centre of the hump, and one down the flat "valley". If you have to go over them centrally, then go even slower!

This is a moderately well known phenomenon within the tyre industry.

The damage is caused by one sidewall taking all the load, coupled with a lateral sheer.

stewright · 24th March 2007, 23:34

i see .. so when one's in the valley and one's over the top of the hump the individual tyres are loaded the same on both sides.

makes sense

just more uncomfortable. i always tried to do it so it was most comfortable .. will change my driving ways i think!

cheers for the info

Pottsy · 24th March 2007, 23:38

Point 4 on this page.

And here.

stewright · 24th March 2007, 23:41

Very interesting .. Thanks for the links Pottsy.

stewright · 24th March 2007, 23:44

I remember i used to love driving over the full with humps in my 205 on the way to school. Rev up lots and floor it .. used to get all 4 wheels off the ground. Uncomfortable landing though .. the suspension was a bit old! .

I won't be doing that when i get my new civic of course.

323GT-R · 25th March 2007, 10:32

Tyres are Yokohama AVS DB. I've been impressed with them up till now... They've lasted well, and on the occasions I've tried, they seem to grip fairly well too. They had about 3mm tread left, so I was getting ready to replace them in the next few weeks.

Pottsy, interesting point, the inner and outer sidewalls have both gone the same way though, right at the point where they meet the tread. Fortunately for me, there aren't that many speed humps round here, and I tend to go slow over them, as the Civic is a bit too firm to do anything other!

It looks like the layers of the tyre have seperated, and air got between them. Eventually the front passenger side one blew out on the shoulder where the sidewall meets the tread. I don't think the drivers one would have gone on much longer. Fortunately, I was doing about 50mph on the M5 when it happened, so no damage to anything else. Called Honda assistance, who arranged for the AA to take me to the next services and get a mobile tyre fitter out to replace the tyre. After trying to replace the tyre, and finding my delear had put the locking wheel nuts on with an air gun, the AA had to be called out for a second time to get the lock nuts off. Eventually got home about 12:30 am!

Same lol, Thought he was going to say Michelin's

The Phantom · 26th March 2007, 12:36

If that damage is on the inside wall of the tyre (ie the bit that no one will ever see unless thay take the rubber tyre off and look inside) then I would say that one of two things will have caused it.

Manufacturing defect or rough install on the rims. Either way I would bet dodgey batch of tyres.

Impact on a speed hump/kerb/pothole shouldn't cause interior damage to a tyre. Exterior maybe but not interior and there would be noticable deformation of the rim to produce it.

323GT-R · 26th March 2007, 13:56

It's on the inside and outside of both tyres, which make me think it's a manufacturing defect, or possibly as you say, damage during the fitting.
