No more runflats
Discussion
Finally bit the bullet today and changed my EMTs for Michelin Pilot Sports. Same price as EMTs so not cheap at £200 per corner.
Is the ride improved? A little. The effect is almost equivalent to one position on the F45 switch.
Is the handling improved? Yes. Particularly the tendency of the back of the car to hop sideways on mid-corner bumps. Very reassuring.
Grip? Don't know yet but they do feel good in corners. They also squeal a bit under good old kickdown!
Overall? Time will tell.

Pretty much my experience and I am about to buy my second set. There is the conumdrum thought that the Vette designers would have designed the suspension to work with the harder sidewalls of run flats - but I am convinced the handling in the dry is better.I assume you got SP3s?? I have SP2s and at the time there was a new version about to be released.
Are yours homologated to Mercedes?

Nope they are don't run flats unless you have some goo and an inflator in your boot

Run 'em in gently for the first 50 miles or so - even the best tyres will have the remains of the mould release agent on them and a tread surface that needs a bit of scrubbing in which means they won't have as much grip as they will do later. Don't want you sliding into the back of someone on the way to the Fairmile tonight !
Regrettably can't do Fairmile tonight but plan to get to Wheels at Aldershot on Friday with meet at Fleet. Reason for tyre change was the ride and handling limitations of stock C5. Before the change the car had plenty of power and grip though not enough handling; but it's a great car that I've been enjoying for 6 years. Ride is a bit smoother on the Michelins (especially ridges and pot-holes) and the handling is improved. All down to losing those stiff EMT sidewalls I guess. I have reservations about life without a spare but if the car's a little improved then hopefully it's worth taking a chance. Certainly cheaper to change the tyres than buy a C6 at the moment! What I eventually want to do is see how the C6 rides and handles by comparison.

Yes but you will bugger up the TPM's on a normal C5 in using this. If you value the TPM then run-flat or the AA is the only real option. Unfortunately the only available emt is Goodyear in the UK, unless you import others specially (my preference is the Michelin Run-Flats or ZeroPressure)
The tyre dealer I used had Bridgestone run-flats in stock in C5 sizes and slightly cheaper than the Goodyear EMTs or Michelin Pilot Sports. The Bridgestones are apparently the runflat tyre for large BMWs. Although tempted to give them a try I decided there was a significant risk they might be no better than or maybe even worse than the Goodyears which would be frustrating.
