I noticed that the cost of tyres has rocketed and the MP12's are £450 each or £2k for four, about double a 911.

So what do current owners guess they will achieve mileage wise? Presumably the rears wear faster?

Way off Moncho,3500 miles so far,very little commuting all balls out fun,and so far im seeing little wear.This has a lot to do with the compliant suspension and very advanced TC,so i reckon 10k miles plus or more if you using the car as a DD

The first London demo was at 9000 miles with tread in OK condition , maybe a couple of thou left.

They do,its just a little subtle in been rated M1 on the sidewall instead:D

Andy, would you be reticent to try non-spec tyres like Michelin? I seem to remember Mclaren saying the suspension design allowed a softer compound???

Andy, I have checked and the PZ's are a softer compound due to Mclaren suspension compliance and thus I wonder if non-spec tyres l, like the Mich SS, would mess up the stability/traction settings........maybe harder compound equals earlier brake away so no problem.....but.maybe it would invalidate the insurance.....must find out I guess.

I might try the michelin ss,seen as the factory 458 has suddenly started braking all track records with this new tyre being the main difference!!!!,and its superb in the wet aswell as being as quick as a semi-slick.:rolleyes::rolleyes::rolleyes:
Still i might try them anyway;)
Andy, I called a Michelin Techhead at their HQ. He helped me last year when tyres for one of my bikes were unavailable and the bike manufacturer would not approve Michelin but at the time Michelin had completed their own testing and he sent me an email confirming approval.

So he said he would be reticent to use other than Mclaren approved as the sidewall and tread/compond/construction specification become important at speed and when hot under load, especially high torque load.

However I do wonder if we are talking about performance at the extreme and mere mortals don't get there?

It is an issue on bikes as the tyres work different to CAR tyres in that they have to maintain profile for stability.

However he expected Michelin to go through a testing programme with Mclaren at some, unconfirmed, point.


I have now been quoted £300 for the PZ rears.

His point was that they had engineered the tires jointly with Pirelli. Sheriff also commented that the various electronic aids were programmed based upon the grip characteristics of the tire design.

The tyres have a Mclaren designation both in the nomenclature and physically.
Given the comments from Michelin it makes sense to me to be cautious, especially if you have to ask an insurance company for a 'contribution'.

Michelin will get approval, probably in 12 months or so.
