New Tyres, WTF????

[Six Days]

Just had new tyres all round on my wife's 116i Sport. Had Goodyears on and changed to Pirellis (all runflats). Rears went on first and seemed to alter the feel of the car a little. Then after about three months we had new fronts fitted. The steering is significantly lighter, but stranger still is the behaviour on poorly surfaced roads - it feels much more mobile than before and under braking you need to be ready to adjust the steering to compensate for tramlining. Anyone else experienced this?

My runflats tramlined horribly, which is why I replaced them with proper tyres.

They seem very sensitive to pressures, so maybe try experimenting a little?

Run flats ruin cars. Fact

The Pirelli run flats are terrible!!!!!!

Get them off now!!


I have just thrown a set with 6.5mm all round out, I hated them that much.

The Pirellis are hopeless... which is unfortunate if you,ve just bought a full set.

I swapped to Bridgestones and they are a tonne better.

I was used to rfts on my Z4 but the Pirelli euforias on my 120d M Sport were frightening in wet and/or bumpy conditions. Barely 'fit for purpose' in my opinion.

So if you are determined to stick with the Run Flats which are the best???

I'm currently on the Bridgestone Protenza's (SP???) great tyres (in my mind anyway), seem to have good grip and still strong @ 24k, only had one scare during harsh breaking in the wet at XXX leptons when spotting a scammer van.

I'd be interested to know which Pirellis went on as Pirelli make two run-flats; the Euphori@ (which is reputed to be appalling) and the P-Zero (which I've not yet seen any reviews of.

I'm on the Dunlop Sport SP01 and very pleased with them. I'm on about 3mm and will change them at 2, however initial checks seem to show that there aren't any in the country in the size I need, nor do Dunlop know when there will be. I have to use Kwik Fit (lease contract arrangement) and they're also struggling to get the Bridgestone RE050s.

Really hoping the supply issues have changed in a few weeks when I need those tyres. I'd really like the Dunlops again as they've been really, really good on the 1er.

Well hang on.

I had this problem when I fitted new ultracs to the front of my car. But after a few hundred miles when they were properly scrubbed in there were fine.

Well better than fine, there were excellent.

If you're running them at upper end of inflation pressure range they will tend towards tramlining. New tyres at high pressure have a slight difference in contact patch and dependent on the shape of the contact patch (i.e. design of the tread for water evacuation) it may require some bedding in to get the best out of it.

Bear with it for a while (obviously maintaining sensible pressures or else run the risk of under inflation...wear/safety

Of course, I fundamentally detest Pirelli esp in the wet...so some people have already suggested alternatives...depending on your patience levels and wallet size...I'd opt for Michelins myself.

[dasherdiablo1]

Michelines all the way.....put a full set on my wifes Z4Coupe and it is a different car from when it had the horrible Bridgestones on there.

Almost as good as real tyres.....

Disagree. The Dunlops I have are excellent.

They're the Eurfori things. Tyre pressues are as per BMW instructions - may alter a bit to see what difference it makes, but will see if they bed in first. BMW dealer recommended them, said lots of their customers preferred them... seems that most BM drivers actually have little interest in driving If they don't bed in and improve much, I will of course be giving some feedback to said dealer. Not sure we can justify the cost to bin them yet.

Apparently the earliest Dunlop can provide the 215/40/18s for the front and 245/35/18s for the rear is the 19th November. Eek. I have about 3mm of tread left on the rears..

[BMWBen]

Another vote for the dunlop's here - pretty good tyres.
