Why is it increasingly difficult to get anything done well these days? Answers on a postcard...

Because there is a massive competency crisis on top of a lot of trades just not giving a fuck and having shite standards.

Yeah that's why I stick with Run flats as I prefer the turn-in feel of stiff sidewalls. The PS4 run flats are very good indeed. The CS7s are extremely grippy, impressively so in the wet, but much much vaguer turn-in that run flats. I hate vague steering, so happy to sacrifice a bit of mechanical grip for a more chatty helm.

Nah, it's not. A colleague has an Ioniq 5N and he gets that kind of range also. It's just how they are. I was looking into getting one myselkf through Tuskers as I like the look and performance of them, but he advised against it

People forget all cars have issues. I mean, 335d and 330ds chewing through oil, cracking DPFs etc plus all the other general ICE woes. I'd rather have a short range as the only issue personally. Constantly fixing ICE issues is getting old and expensive.

Do you say shit like that in pubs when people change the conversation?

I don't think I could get past the first week with that sort of carry on. I realise a lot of people don't do the sort of driving I do but losing twenty minutes every 120 miles for a charge is insane, it would easily add an hour to my day over a weekend. It's almost as bad as the nationalists wanting to reduce all A roads up here to 50mph which would add similar times. Combine there two and it would genuinely make some journeys that are currently normal a complete no-go on a normal day. A car is freedom to me first and foremost, but all this nonsense really encroaches on that.

It's an interesting point, I like a sharp turn in but the downsides of run flats, despite the stiff sidewalls, is a general lack of feel. Additionally, while the PS4S are softer, it's what I think makes them so settled on rough and broken tarmac where a stiff side walled RFT gets unsettled and can feel fidgety or lead to it stepping out. Even really sticky stuff like Michelin Pilot Cups and R888R GG's etc can get unsettled when the tyre can't properly deform to keep the tread on the road. With sticky rubber on those tyres there are compensations, but on a normal HP road tyre there just isn't enough movement in the tread to hang on when the wheels are very lightly weighted in a turn, like where the road drops away on the inside and the outer, loaded, tyre hits a broken surface. For my driving and the roads I enjoy going on, there is definitely such a thing as too stiff. Fast sweeping smooth tarmac and tracks are a different proposition. Where the PS4S is so good is being consistent from corner to corner regardless of the road surface, and an ability to really hang on when the road surface is terrible. That it wears better than most other HP tyres is all the better.

This is where I feel that the MP4s strikes a really good balance. Ultra-high performance compound and, in XL rating (which I always buy), stiffer sidewalls which provide immediacy in turn-in, great stability and predcitability through the corners, as well as eliminating pretty much all of the bounciness that is typical in non-XL tyres. A bit like suspension, they are stiff but not crashy.

The difference between MPS4S and MPSS on track is significant. My MPSS would literally melt on track (the compound would get so soft that it would roll-over onto the faces of the tread blocks) whereas the MPS4S just soak up the punishment.

Some other tyres have been ranked higher than MPS4S in tyre tests during the past year or so, but they will remain my tyre of choice.

I had always assumed the MPSS was a better track tyre than the MP4S so it's interesting to hear you say they went off quicker.

Your last point to me is the key bit though. On a road tyre the ultimate metric is the subjective handling IMO, so while grip is important and you don't want a plastic ditch finder, what you want is predictability, progression and communicability so you can feel what's going on underneath you with changing road surfaces and grip levels, and for it to do what it does consistently without snapping on you. I've always liked Michelins right back to the original Pilot Sport, and while the PS2 was a significant leap ahead in grip, it was the feel that marked it apart for me. Good Years are good, but just not quite as good as the Michelins.

The thing with the tyre reviews is that they're either absolutist like the German ones, which misses out on subjectivity, or you get subjective tests which use the tyre on a smooth track and then try to extrapolate that to a 'road handling' score, except that isn't what I drive on, and what makes a tyre feel good on that sort of surface is what can very easily make it feel crap on the local roads I enjoy a good hoon on. Just look at all the cars ruined by 'tuned on the Nurburgring'. As I'm not driving against the clock on the road, the PS4S is what I was most happy with and it would take a lot to sway me away from that choice next time simply because it makes the car such a joy to drive. Winters are an absolute nothing-but-RFT situation but I think I'm going to ditch the PZ4 RFT's when they're done and go back to the PS4S. At least in summer you have a fighting chance of spotting the craters in the road surface.

Interesting to read; my pal who has a dedicated E46 330i track car wasn't happy with the PSS tyres at all. He loves his R888s and drives to tracks on either PS4s or Eagle F1s (he has a few sets of wheels)

I'm looking forward to giving the PS4S's a good run when I get the Protrack wheels and have them paired up; the weight difference should be very noticeable too!

I found the MPSS to be an interesting tyre. Superb handling in the dry, less traction than I need (RWD, high torque), not as durable on track as I was expecting, and not great in the wet.

The MPS4S beats the MPSS on all those criteria.

Hey - I've picked up this thread as the 19" run-flat P Zeros on my F36 430d are coming due for change and I'm thinking of changing to non-run-flats mainly to improve the ride. Probably Michelin PS4.
Is there an issue with the tpms by going to non-run-flats?
Has anyone thought of buying a space-saver wheel as back up? I've seen 18" spacesavers for about £150 and 99% of the time I can afford the boot-space. Of course I have breakdown cover too.
Thanks

I'm just replacing run flats with non run flats on my Mini, and new wheels. Told by the wheel supplier than they just work with the new tyres (although I am buying new as the current ones will stay with the existing wheels)

Nope

I run x2 sets of non RFTs on 18s on our F31 (came on 19" 403Ms with RFT Bridgestones)

Summers are 18x8 405Ms with Goodyear Assym 6s and winters are Stule 397s with Goodyear Vector Gen3 all seasons. All 235/45/18, non RFTs and I fitted new TPMS sensors to them whilst they were getting a full refurb and new tyres fitted/freshly balanced etc

There's a reseller on eBay that sells genuine BMW TPMS for the F3X series at c£100 delivered for all 4 corners

I have a decent tyre inflation/repair kit spugged away under the boot flooring and breakdown cover too

Interesting!!! I like the idea of same-size tyres all around. The only time I’ve had a puncture in the last 20 years the hole in the tyre was too big for the gunk to seal it up! I probably just need to get past that and get a repair kit!

Same; but happy with the equipment I've got and breakdown etc

Having same size all round I've found that the F31 handles and rides better and has a better turn in feel

Plus the OEM 18" 405Ms are forged, so c9kg a corner; compared to the 397s which are 13kg a corner!

Winters (397s)



Summers (405Ms)

This just started with a question (in my head) about the best tyres to replace my worn Pirellis with...and now I'm in to new tyres plus new wheels plus an extra set of each for summer and winter plus a repair kit! A line is going to have to be drawn!

Hello all,

Can I please remind all of the forum rules here and specifically:

1) Respect. By far the most important rule here. Through the generations of BMW, enthusiasts have come together for the love of the car and the community. So the basic rules of real life apply here, show each other respect and you will get respect as well. Don't bash someone else here because you feel like it. Derogatory or insulting remarks will not be tolerated. This applies to all corners of the site - including posts, profile visitor messages, and thread tags.

3) Disagree, don't attack. Disagree on topics, but try to leave it at that. Just because you don't like someones opinion on the car's engine, doesn't mean you should call him and his mother all sorts of names. Disagreements are awesome, and you should call someone on something you don't agree with, but don't go out of your way to insult and flame someone. Please consider if you would say to someone's face the same thing you are posting.

Of course we reserve the right to ban/restrict members in accordance with these community rules, hopefully it never comes to that tho!


Thanks, Mani

The pilot sport 5's aren't available in my size on 275/40/R22. Perhaps as new maybe they'll add that size in time for the next set in 3-4 months.

I wonder if that's down to them planning for it to be a PS5S tyre whenever that finally gets released?

What do you think to the 'flag' type wheels?
I have the same on my A4 and still can't decide whether I like them or not.
They look easy to clean, but they really aren't IME.
