So I have been looking at a set of p zero for my 435i and am considering non rft

Looking on popular tyre sites they list all the tyres avaialble for my car. When I look at p zero tyres there are literally 5-6 choices of the same sized tyre but all different prices because they fit either an Aston, Audi or merc. There isn't a Bmw one because they want to steer you towards the rfts instead.

The cheapest but same sized p zero is £40 less than the Aston Martin badges one.

Why???

Supposedly the car manufacturers request slightly different compound make ups of the tyre manufacturers. I can't see it really but happy to be proved wrong. As said, just AM/Porsche e.t.c. tax.

So interestingly I get the Aston Martin point but there are 5 other Pzero 255 35 R19 96 Y tyres for sale that are cheaper.

the cheapest is a Merc version Mo1 at £154 each fitted, then the next one is another merc version but that's a MO and that is £159 a tyre fitted... then you have another MO version (so the same as the last one) but that is £163, then an Audi one at £163, the Aston is £181, the Lambo is £184

the Run Flats are 255/35 R19 W (92) but they are over £200 each

Have a look at Vredenstein Ultrac Vorti:

They're available in the 19" staggered fitment. I'll probably we getting them when my S001 RFTs are replaced.

There are at least five different types of Pirelli PZero, including the 'New' PZero so it's easy to end up comparing completely different types. It would help if Pirelli gave them different names, instead, they rely on the retailer providing the full variant name PZero/New/Rosso/Asymmetrico/etc. Often they don't. Historically, the PZero was aimed at heavier performance cars and got a bit of a bad press when it got put on lighter-weight cars like the BMW 2 Series, where it really didn't shine. In the reviews I've seen, they also tend to be hidden becuase they tend not to come first in a any one category, but score well overall, and especially when they include more 'esoteric' tests (e.g. things like aquaplaning resistance when cornering, not just in a straight line ...).

The runflat debate rages: you'll see them disparaged a lot. But it's hard to know, as I image few people who've swapped to runflats and been disappointed are likely to post that they made the wrong decision? In my case, I've been the beneficiary - after cutting a sidewall on a low wall my 330d Touring runflat deflated on the motorway and it was no great event - I got home OK and to the dealer the next day and got it replaced. A gunge-kit wouldn't have repaired that sort of damage on a non-runflat, so I'd have been stuck on the hard shoulder waiting for a flatbed or had to fit a temporary tyre. And I'm not sure that the deflation would have been as controlled in a non-runflat.

So interestingly I have swapped from rft on the e90's and that was like night and day in regards to comfort, handling and the disappearance of tramlining and noise.

I previously had a 335i touring f31 and at the end of a set of run flats I purchased another set but they were Goodyear rft. They were good, as good as the non rft on my old e90 so I stuck with the rft.

On my current f36 435i the dealership fitted a new set of Bridgestone soo1. I find them really fidgety, and on tramlining they sit between the rft on my e90 and the rft on my old f31.

So is it that bridgestones are rubbish or is that the geometry of the coupe series of the f30 is more sensitive to the road than the touring and I should go the non rft root?

I've got S001 RFTs on my 340i and don't have any real issues with them (as long as I avoid potholes/bumps with steep sides). Had them on my E92 335d and also found them to be good.

It's very commonplace. Even some mediocre brands will have OE specific tyres.
As a result, there are cost implications of development/materials that have to be accounted for - hence the disparity compared to standard replacement tyres.
