Tyre sourcing problems

My Boxster I have not long had has Continental Contisport contact N1 tyres fitted all the way round. The problem is one of the rears needs replacing. However they dont make the Contisport N1's anymore but they now do Contisport N2's. Presume it would not matter fitting a N2 if all the others are N1's?

There is also another problem no one sells the Contisport Contact except Kwik Fit. I've tried protyre, blackcircles, mytyres etc. I read somewhere that Contisports are no longer Porsche approved. Which brings me to another problem, when the rest needs replacing if i'll be able to source anymore N2's? or shall I just source another make?

Anyone help?

Why only replacing one ? - if its a puncture, and you are covered under warranty then you might be better of calling Porsche assist and letting them sort it out for you, as they are having issues themselves and the end result could be a new set of Bridgestones for the price of a single tyre as was the case with member 'slapshot'

Michelin and Bridgestone are the only approved tyres for the 987 now in 19 inch - and Michelin are as widely available as rocking horse poo !
 
Thanks for the reply, forgot to say the tread is on the limit, all the others are ok though 6m of tread+.

I also noticed one of them has had a puncture repaired, does this matter on 'Z' rated tyres?
 
One tyre on the limit and the others 6mm ?- sounds a bit dodgy to me, if the wear on the bad tyre is uneven then suggest you get the alignment checked. Opinions differ on puncture repairs - i had a repair completed and i used the tyre no issues for 5k miles before it wore out. Same on my old Boxster. The OPCs will not repair tyres, but then they want to sell you a new tyre - Porsche official line is you should not repair, i believe thats more to do with the fact they have no control over the quality of a repair and they are covering their backsides .
 
As there is quite a difference in the tread left compared to the others I doubt whether a alignment problem would the cause this much difference? especially as its a rear tyre. The car drives perfect and does not vear to the side at all.
 
If the wear is even across the bad tyre , then your alignment and/or pressures should be OK - still doesn't explain why its worn so much more quickly than the other side though.

Back to your original question - Porsche official line is not to mix makes or N ratings, even on the same axle - the choice is yours whether you take any notice, you're probably not likely to ever notice any difference.
 
It's probably because the previous owner had a puncture/replaced that one tyre when all the other tyre treads were around 6mm or so.
Fast forward to when the other tyres were replaced, and the punctured/replaced tyre is now on say 4mm.
Fast forward to now, when the other tyres are on 6mm and the replacement tyre has punctured and is on 2mm.

Looks like a previous owner did what you're thinking of doing, and when there's 6mm left in the other rear tyre it does seem a waste.

The Golden Rule is never mix on the same axle - your post implies that it's ok to do this.

Yes it does John - its a bit ambiguous, i meant to run differnt N rating on the same axle, different makes is a no no to me - However, there's plenty of cars running round quite happily with different makes of tyres even on the same axle. Whether its good practice is another thing, but its not illegal.

Although the way tyre shortages are at the moment, running different N ratings side to side, or front to back is looking a reality for lots of owners.

At £250 a tyre you're not going to change both when one has 6mm - at least i wouldn't !
 
Back to the original post, I'll have to try and source 1x contisport contact, anyone know where I can try and find one other than Kwik Fit who want £175 a tyre!?

 
No idea whether they are local but you could try Buckley Tyres in North Wales/Cheshire border - they seem pretty well stocked with N rated at present, and are a Conti dealer - 01244 544575

 
Don't know if this will assist you but I've had a similar problem, my Michelin 19in N1 rears were getting low (2.6mm) tried everywere to purchase some, with no joy, I went to Porsche Uk customer service, and they agreed that as their were no tyres availble and they would put me a full set of Bridgstones on if I pay for the rears they would pay for the fronts total cost £535 (4 tyres), I bit their hand off, I've now got 4 new Bidgestones, its worth checking

Guys, need your expert advice.
What is the difference between the various N ratings?

I have found a great deal on Bridgestone SO2 N4 tyres through Tyre Shopper for my 2.7 Boxster (17" wheels)

See : http://www.tyre-shopper.co.uk/home.asp

A set of fronts and rears for £486 sounds too good to miss!

My understanding is its the compound of the tyre, I was adivised by OPC not to mix compounds, hope that helps

Tommo
 
The first approval of atyre would carry a N0 rating, any subsequent improvements or changes have to be re-approved, at which time the tyre would get N1, N2 etc etc

 
I kind of think this tyre stuff is a bit of over hype. In the past, there were radials and cross ply tyres. To mix those on the same axle, was I believe, made illegal. Now I think this was born from the fact that crossplys used to let go before the radials and give a weird handling characteristic. However these days all tyres are radials with somewhat different tread patterns. Now I suspect that the speed rating does make a difference if you go beyond the manufacturers limit, but who really has anything but Z on a boxster? huh? I ask you? So now were down pretty much to tread. And I know that there are purists out there that think this makes a huge difference and Im sure it does on the track. But hands up how many people think that gary is talking about zinging his boxter round the track. hmmmm yeah thought not. So in summary get a tyre of the same rating and get one thats available.
 
Rod_dude.. saddly ... does insurance companies think like that ???
So its a risk . if you total a car with mixed N1 / N2 tyres... will you accept the insurance company ruling ???? whioch may be ... no payout .....................
 
Believe me, different Porsche approved tyres feel totally different in handling characteristics, and I'm talking about on the road!

There are some I like, and some I hate. It does make a real difference.
