Tyre brand advice please

[Justlovethelook]

I think all run-flats are like bricks regardless of brand, model; it is the nature of the wall of the tyre.

It is interesting that the Potenza RE050A none run-flat version is no longer available; they discontinued it.

Seen these on Camskill lately....unless its just existing stock that they are running down.

I'm on the phone with BMW dealers again, both dealers now giving me different information about bloody speed ratings for tyres.

One says

225/40 R18 - front - speed rating should be Z
255/35 R18 - rear - speed rating should be Z


The other says:

225/40 R18 - front - speed rating should be W
255/35 R18 - rear - speed rating should be W

However, my tyres have on them 88W for front and 90W for rear, WTF.

Neither BMW dealer can tell me what the speed rating should be for non run flats, they only have speed ratings for run-flats.

So, I've asked them to check speed rating for M version of my car with same size rims and let me know what they should be.

If I'm going to spend money, I want to get things like speed rating nailed.

I'm going to bite the bloody bullet and go for a set of Vredestein Ultrac Sessanta as I don't want to spend more than £550 all in, in case the ride is not secure and is iffy, as BMW suggest it will be.

So dealer know what they are talking about

WTF indeed After all that you could at least have the decency to have gone for the RFTs! If you find the ride is "not secure and is iffy" get your dealer to check and explain the sport button "suspension settings ", if it's still 'iffy' let me know and I'll take the Vreds off your hands.

My Potenzas just gone were the original factory fit so
Front 225 40 R18 88W
Rear 255 35 R18 90W

Interesting my Dealer's Tyre Specialist had the higher rating Michelins in stock but recommended getting the correct tyre ( which he did overnight ) as they were cheaper and the correct Z4 rating

I appear to have a gem of a BMW Dealer

I think you are right a11y, forum life is definitely not for me, I have a bit more intellect than that.

I'm outta here, goodbye all, squabble amongst yourselves.

Bye.

Just slipped on my flac jacket and.......................

Home now from a trip to my Dealer to replace the RE050s with Michelin PS2 ZP and I don't know how West Sussex council have done it but the Chichester bypass which is on long truck rut
has by the time I returned home apparently been resurfaced and not a truck rut to be found
seriously I cannot believe the difference car is transformed goes where I point it stable quieter .......I could go on but most important I feel I am in control rather than the tyres
Pricey but what the heck the car is now enjojable to drive

Cheers Gannet

so glad you're happy with them

it does indeed transform the car

we all seem to have scared Nigel-Z4 off though

I think cabin fever is the culprit - as for me I'm going out for a blast in my roadster shod with Avon ZZ3'S - no doubt someone will be along shortly to say how crap they are
