Non run flat tyres
- Thread starter Sidey?
- Start date
best all rounder.. Michelin ps4, tons of options though depending on budget, if you want a quieter tyre try dunlop sportsmaxx, best all rounder on a buget.. Vredstein ultrac vorti, just all imho 
Be carefull with non run flat tyes, in france for example, insurance companies don't "cover" an accident if your Z4 (E89) don't have run flat tyres.
But i think in UK, is not same rules ?
I agree with people who remove Brigestone run flat tyres (originals) to non run flat
Ps : Michelin PS4 are very good as you say for E89 ?

I double checked with my insurance company before changing, they weren't bothered at all. That's in the UK
I got rid of those Bridgestones a fortnight ago, got a decent deal from my local f1 autocentre for Goodyear Assy 5 on each corner. Car holds the road, quiet, no tramlining, dsc light doesn't keep coming on - feels like a different car.
Hastings insurance weren't fussed about using non-flat - bought an ectric pump and can of slime in case of a puncture

They are currently getting very good reviews along with the Goodyear Asymmetric 5s..
Michelin no longer the undisputed leader..

I understood that Premium Contact was both a better handling tyre or at least equal to the Sport Contact 5 series but much better wear rate..
Certainly the Sports Contact 3s and the 5s both wore out very fast on my car...
I've been enjoying the Vredestein Ultrac Vortis on mine, the car is far superior handling than on the runflats, far less crashy too. The wet/damp traction is significantly improved, as an Aston Martin DB11 found out when pulling away from the M6 toll 
My only criticism is that when temperatures drop below 5c it loses traction a lot easier, but that's what a winter set is for I suppose...

It is described by them as an ultra high performance summer tyre..so as well documented once below 8c ish progressively loses performance..
IMHO for Z4s in most of the UK an all seasons tyre may be the best solution for winter and the variable condition long spring/autumns we seem to have..winter's are great for daily's but badlly wear / go off as temperatures rise much above the 8-15 c range..
If you're faced with snow regularly winter's prevail but for most of the slush/snow we see in the UK I think all seasons are a better compromise..
Maybe finding all season run flats in the correct sizes may be more difficult..
