My new 4GC arrived shod with these, unfortunately.
My question to those who have persevered with them is, Do they improve with wear? If not, then I will have to pay out to replace them as I'm not sure I'll be able to tolerate the tyre roar and unsettled ride at speed

Remove them at about the 6 month mark, but regular tires and put the runflats back on at the end of the lease

That is if you leased. I realize it is unclear from your post

You don't mention the exact Potenza: Do you mean RE970AS? S001? What?
You also don't mention the size.


1) All performance summer tires are noisier than all-seasons.
2) All performance summer tires usually are noisier than all-seasons.
3) If you compare apples to apples, ie an OEM summer RFT to the corresponding go-flat, the performance is quite close, within 1%-2%. Although RFT's are a bit noisier.
4) Many are comparing the OEM RFT to the latest version of the go-flat. For instance, Michelin Pilot PS2 ZP (RFT) to Michelin Pilot Super Sport (or PS4) go-flat is not a fair comparison.

FYI, The OEM Potenza RE050A RFT on my 2010 lasted a bit over 20K miles.

They're S001s in 19"

I have the S001 tires and they perform pretty well. I'm glad I got them over the all-seasons. But i have 18s so maybe some more comfort there.

What do you mean by unsettled ride?

Transmits every imperfection in the road into the cabin

Should read "All performance summer tires usually last a shorter time than all seasons"

Don't know what my brain is doing today...

I think they settle in. I actually like them, aside from road noise. They are touch rough but I was happy with performance. I switched to continental Dws 06 for "winter plus" months since I HATED my last set of snow tires...

The CPO 435i came with those exact same tyres. Took them off asap and sold them to get a set of Mich PS4S, though note i live in warm climate so never need snow/cold weather rubber. We must remember the suspension includes the tire sidewall flexibility, and the RFTs have very little of that. On the wife's 2013 X1 the RFT work and feel fine, yet on the 2014 435i with 704 suspension i didn't like it one bit. RFTs are a compromise in handling, compromises maximum grip potential, etc. compared to 'the best' tires available today.

Sell RFT ASAP for something with a less stiff sidewall.

My previous 2013 BMW 335 had Bridgestone Potenza S001 tires as well. They are indeed a bit noisy and the degree to which one notices transmission of road imperfections is highly subjective. I did not like them but found the performance to be acceptable. Pirelli RFTs are not as harsh.

My contisport contact 5ssr RFT drive like shit too...on my 4gc but i own bought this car and i dont like throwing them out.. i already have 12k miles on them. Probably have to drive them till they wore out. Suck that there are no good RFT so im going regular tires.

[jv004]

I had S001s till they were worn out and they never improved, they are noisy and rough, especially on a sportier car like the 4series, far worse if your suspension is lower. I tossed them and got regular radial tires and ride is so much better.

I paid for most of the car with cash as I did a part exchange. I have a small amount of finance (just to get the finance contribution from the dealer, of course )
So, I'll need to sell the Bridgestones if I replace, which I want to very much - but who the hell is going to buy a set of tyres which are this bad?!

Goodyear Eagle F1 Asymmetric 2's are the best RFT's I've driven. Nothing beats a regular tyre, however, as you say

Sell the tires on the classifieds section then buy new ones. People buy these tires when they need to turn in lease so if you make value good for them you can cover most of the cost of some highly rated Michelin's or continentals

Echoing previous recommendation: sell these tires to another BMW owner who will use them during lease return.
