340D tyes

[Theblur_20]

Afternoon all, very unexciting discussion....

Got a lovely 340d touring and love the car, but I'm looking to replace the tyres as previous owner has a mixed set of tyres on it.


Do I either replace with the standard
P zero Pirelli P Zero (PZ4) (runflat)
Or
Michelin Pilot Sport 4 S (not runflat)

I know there's probably a huge endless discussion on runflat or not but specifically on the beat tyre I've heard a lot of good things about the Michelin PS4s.

What are you experiences?
Cheers

xDrive? If so; stick with the OEM spec sized tyres; but go for whichever tyres you want

PS4s are great tyres; personally I'd run Goodyear Assym6s or Conti Sport 7s over them. Both excellent tyres also and yes, I'd go non RFTs all round

Exactly what I've done with our F31 (Goodyear Assym6s for summers, Vector Gen3 all seasons for winters)

Just have a decent tyre repair kit in the boot and away you go (plus decent breakdown obviously)

I do get why some folk stick with RFTs (more so the latest ones as they seem to be getting better & better)

What diameter wheels?
I have a 335d xdrive saloon. I changed my 19” Pirelli Pzeros, for 18” Goodyear EfficientGrip. But maybe I would go for Goodyear Asy 6 now. I have always used Continentals in the past, and never been disappointed, plus they do a pretty good all-season too.
As for runflats; in North West Wales, local road surfaces are pretty good, so I have kept runflats. If I lived in the countryside in South East England, or in Scotland, I would perhaps go for non-runflats, because of the poor road surfaces.
I certainly would not go larger than 18” wheel diameter.

For that car I wouldn’t bother with the UUHP 4S.

Go for the PS5. A better all-round road tyre IMO and you’ll get more mileage out of a set compared to Conti.

I had the PS5s on my 130i; was glad to see the back of them. Didn't rate them at all; not better than PS4s in my experience

Haven't tried the Conti's yet but they're what I'll be going for when I sort some new alloys for summer tyres. I don't do much mileage at all, so wear is NA for me really

Yes it's Xdrive, and it's 19" rims ( shadowline variant)

Price wise I can't see much in it between conti and the PS4s, it's roughly £950 for 4 tyres to be fitted. ( BMW bit pricer than my old car lol)

I can't atm see the need for runflats as like you said you'll just use a foam canister either way( previous work BMW had runflats and still needed a canister)

Also it annoying BMW don't make room for spare wheels these days .

Have a look at Camskill for prices as well; you'll have to get them fitted locally, but generally their prices are hard to beat

Runflats are not what people think though, they are not supposed to be driven on when deflated, if you do, they will inevitably need replacing due to internal damage.

The only real advantage to RFTs is if you have a sudden deflation the car is easier to get to the side of the road safely, but the tyre/wheel still needs sorting immediately.

They are not RUNFLAT so that they can be driven on and continue the journey when flat.

Give the PS4 Zero Pressure a try if you want run flats. Really good tyres.

The Conti Sport 7 is also very good, as is the PS4S, but the CS7 is better from cold and better at the limit. The Eagle F1 SuperSport is another good one, but they're not the best in the cold and need more heat in them than the PS4S and CS7 to perform.

But if you have winter wheels and use them, then none of those shortcomings matter.

If I had to pick one as an all year great all rounder, it would be the PS4 ZP.

One thing always over looked about run flats is how the steering feels. It's not exactly bursting at the seams with feel to begin with thanks the Thyssenkrupp ball bearing steering rack, but I found non run flats felt considerably more vague than fun flats, due to the softer sidewalls.

Well actually they are, you can drive on them for up to 50 miles at a max of 50mph, no one thinks you can just carry on regardless with day to day driving though.

You may well bugger the tyre completely but you're not stuck with just pulling over where the puncture happened unless of course the tyre dismantled itself as a by-product of deflating.

I think you may well be VERY surprised on that one, several times I have heard this argument & the surprise at the truth is evident.

Correct, you will still likely bugger the tyre completely, hence what I said about still needing to stop immediately & sort the issue.

Thanks for the heads up, I never thought of PS4 zps, I'll have a look at them Vs the Michelin PS4s.

I totally agree ref the " feel" I've driven rft and non ones, the difference in feel is another reason I want to get rid of them as they do feel heavy in the corners.

One for the masses but do you think conti 7s at around £40 a tyre cheaper is worth it over a set of PS4s? ( Heard the contis won't last as long so is £40 cheaper worth it).

Cheers again for help.

How many miles do you do and what size tyres? Have you looked at the tyrereviews.co.uk Youtibe channel; if not it's worth it IMO

I don't do many miles at all and the Contil Sport 7s will be perfect for my 130i; more so as they're considerably cheaper than the PS4s in the 18" sizes I need

Are you open to all-seasons, or do you want premium summer tyres only (do you run winters etc)?

As said earlier; we have 2 sets of non RFTs for our F31; Goodyear all round, Assym 6s for summer and Vector Gen3 all seasons for winter. The car drives and handles superbly on them and the drive feel is very good indeed. However, they're a straight set and same sized tyres all round

So are you seriously saying you would actually carry on for 50 miles on a flat and knowingly stuff what could be an up to £200 or even more tyre rather than pull over & hopefully manage a £20 repair just because it MAY be possible?

[Pica-Pica]

I certainly would not ‘pull over’ on a motorway, for sure. I’ve seen some ridiculous things; such as a couple standing between two cars on the hard shoulder - volunteering to be the meat in a sandwich!

Depends on work ect, the tyres will be my only tyres I use on the car so guess you can say all season ( although I've never gone out my way to get all season tyres as most premium tyres tend to do alright in everything).

Ref the Michelin PS4s, do you have to use the *BMW versions? I've read into them and seems they designed for M3 cars so yes they are " better" but I can't see how my 340d would really need them over the normal versions. Unless you can think of another reason?

Size wise my tyres are standard
225/40R19 Y 93 Front tyre
255/35R19 Y 96 Rear tyre

Nah; stick with standard PS4s, or Conti Sport 7s, or Goodyear Assym 6s etc - whichever you choose

However; I'd highly recommend Goodyear Vector Gen3 and Michelin CC2 all season tyres; we have them both ands they are superb

I would pull off at the next safe exit/refuge/layby etc.
