Tyre Blow out

[Guest]

Yesterday I had a very scary moment in my 996 GT2 i was travelling down the motorway at what i can only say at the appropiate speed for a GT2 when i herd a really loud bang. First of all i thought i must of hit something but soon realized the car was not reacting properly so i quickly moved to the hard shoulder, when i got out of the car i noticed the rear tyre was completely down so i began to try and repair it with the hardening rubber pumped into the tyre method but to no avail the hole was to big. Now i was in a real situation thinking how do i get my beloved GT2 home so i rang a good freind of mine who is also a mechanic and got me home eventually . So my question is this since i would not like to be in that predicitment again is the any testing of tyres to suggest which is more or unlikely to explode more than the others and whic is the best for the GT2 . My tyres on the rear wheels are at the momnt 315/30 ZR18 oh and one more thing do u have to replace both tyres ?

Eek - bad luck - not a nice thing to have happen []

No need to change both tyres on the axle AS LONG as the other type is identical - if the type or tread pattern is different, you need to change both.

Good luck []

Or if there is more than a certain amount of wear, you need to replace both. My OPC recommended 3,000 miles (ie if the "old" tyre is more than 3k miles old you need to replace them both).

This is more a PSM requirement - I guess that if the tyres are too different in diameter the PSM thinks you are in a constant skid...

Not sure if that's just myth or not. Last week I had to drive around on a barely legal offside rear and a brand-new nearside rear for a few days, PSM didn't seem to have issues with it, although maybe if I was pushing it it might have?

Very scary[&:]
Were the tyres "N-rated"?
It's 20 years ago now but I was following a Rover SD1 at about 80 down the M6 when its front NS tyre blew. It spun, rolled, flew through the air and landed upside down on the embankment. One of the passengers lost his life at the scene.

Since then I've had 2 occassions when I noticed a slight continuous wobble in a car at speed - on both occasions I've stopped and checked the tyres and on both occassions found bulges (one my fault because I'd not noticed the tyre was really worn in one patch, the other for no reason on a fairly new tyre).

The Boxster workshop manual says 30% wear. I can see no reason why other models would not be the same.

Thanks for the replies guys i ended up replacing both tyres for £540 which i think is very reasonable since they came around to my house and did everything on site and was very careful since they had a problem getting the jack under my GT2
