Hi,
Had my 17" Dare V1s with Toyo 205/40 R17 Rubber on for the past 8months, the other day i noticed front drivers side was going down slightly - drove down to the petrol station to fill up with air - it had 6PSI in 
Pumped it back up to 38, got it home, started going down again - couldn't see any form of puncture within the tyre - drove it again that evening and as i was driving the steering wheel gradually got to a 90degree angle. Decided to stop and take a look - the tyre had come about half an inch off've the Rim (towards the suspension side.
Jacked it up and on changing the wheel noticed the whole of the inside tyre wall was f**ked!!!! It was completely split open.
On the inside of the drivers arch there is a lump - anyone know what this is?? the other side hasn't got one.....
This "lump" has been rubbing on my tyre every now again again - at full lock etc and has worn it away and made the inner lining quite sharp.
Anyone have any ideas or similar experiences when fitting 17s??
I'm now rolling on 3x 17s and a 13 for a week - looks POOR!!!

The lump covers the carbon canister which is used to ventilate the fuel tank. I can't undertand why it's damaged your tyre though as the plastic the inner arch is made from is softer than the tyre. However, you should have removed the inner arches before you fitted the wheels to prevent any rubbing. Though it's strange you are having problems because my 18's only catch on the inner arches while turning from lock to lock.

So you think i should've completely removed the inner arch?? Wont this expose the indicator wires etc?? bit dangerous in the wet isn't it??
Whats everyone else done with their Corsa on 17s lowered 40mm on Pi springs??

Are these the same offset as others have used with no problems? Could tracking be an issue?

38 psi in your tyre, seems alot to me, 30-32 is about right?
If you've been running that sort of PSi for a while, was the inside of your tyre bald?
The reason it has probably split open is due to running little pressure in the tyre.
Running low profile tyres and a fair bit of camber puts alot of pressure on the inside of the tyre/wall.
Just check your tracking and keep an eye on your tyres frequently.

Think it should be 28 PSI in the rear and 32 in th front for normal driving.
As for the inner arch you should remove it. Get some pictures up though I'm astounded the inner arch actually managed to damage the tyre.

I'll take some pictures tonight and stick them on this post. Perhaps i shouldn't have put 40psi in, i'll remember that.
That inner arch is really sharp where its rubbed a whole in it.
The pictures can only tell
Thanks for all your help!!

Yea, that could be the problem. Thats a dangerous pressure. You're asking for blowouts and mega understeer.

Standard PSI should be 32 on front and 30 on back (average).
Sounds gutting mate, will have to choose my alloys very carefully methinks.
