BMW M135i Info needed

[Nigel H]

Looks like BM are predicting based on Pablo's numbers

£31,487 will be down to £11,440 after 4 years so 35%. Maybe £13,500 after 3 years so 42%

No too shabby I reckon.

Do these have LSDs?

Nope. They have an electronic diff thing when you switch it to Sport+, but no proper LSD.

WhatCar also reckon that it'll be worth 51% after 3 years so you'd have some decent equity on the PCP deal if you wanted to trade in.

Guys, your advice pls...M135i Run Flat Tyres or not...I'm confused:

> I understand the car was developed with some specific tyres in mind...what were they, RF or not?
> WHATCAR? says "Just as crucially, though, a lowered ride height, specially selected springs and dampers, and the M division's insistence on fitting high-grip, non-run-flat tyres means you can place the car on the road with supreme accuracy"
> RF's are a £0 cost option...ominous
> what are the standard factory fitted Brand of RF and 'normal' tyres?
> if I buy RF and dislike them can I change to normal tyres...or are the wheel rims and/or suspension setting s different in some way(s)?
> what do BMW and knowledgable drivers recommend? what are the differences

All inputs will be read with interest. Thx

Runflats have come a long way since those first heavy unyielding tyres were introduced. The weight penalty is now minimal and sidewall flex is far more in line with standard rubber.

I recently spent £1000 'experimenting' between runflats and Michelin Pilot sports 3's, the difference was somewhere between marginal and nothing. Waste of money.

JB, Lewis, Kimi and the crew might detect a slight difference, us road warriors won't.

Carrying luggage, passengers or allowing your tyre pressures to be out by a couple of psi will have a bigger effect than changing tyres.

Guys, really appreciate all your views...which seem unanimously -ve...which is fine and I suspect correct

I'm just puzzled why BMW would develop a new car (M135i) then offer Run Flats as an option...just to spoil it
I'd love to know what were the M135i's tested by PH, TopGear, EVO, Autocar etc were shod with...they got excellent handling reviews, but on what tyres pls?...and what would have been the equivqlent result on Run Flats?

I remain a trifle confused. Thx

Cheers...

The car is on Mich Pilot Sport no run flats on this car, all tests so far on these tyres.

[warrenosment]

tyrrell...is that as in Ken, JYS, Cevert & 003?...if so, excellent

No disrespect, but may I ask how do you know these Tests were done on non-Run Flats, and from my perspective, why?...why did BMW supply their Test M135i's exclusively on non-Run Flats?...are Run Flats such a truly an apalling option on the M135i?

All the pics & videos on u tube & magazines show the car on pilot sport, product manager from M division also confirms their input to develope with non run flats from outset.

I think the fact that all M-cars come fitted with conventional tyres speaks volumes! Although run-flats may well have improved they still spoil the ride quality (especially on our lousy UK roads) and in my experience the drop off in grip in cold weather is also significant and much worse than a conventional tyre. I've been driving for over 30 years and (touch wood) have had one puncture in that time; therefore, why accept compromised performance 100% of the time to guard against something that happens once in a blue moon? Stick with conventional tyres IMO!

Are you the guy collecting the BMW M135i for that spa town just north of Leeds? They are taking a delivery this week in Estoril (Their first car of two), I was going to call down amd look at it before it was driven away by the happy customer..

No, not me - only got my 335i in June so a bit soon for a change! Reading the press reports the M135i sounds like an entertaining machine so sure you'll enjoy yours when it arrives; while you're busy driving that I'd be happy to look after the Aston if you like?!!!

Cheddar, really interested in understanding more about your £1K experiment that concluded difference between RFT's & 'normal' is marginal...what car; tyres; tests; results.
It seems the overall view of RFT's is -ve
Do both tyre types fit the same wheel...I believe there is only 1 wheel type on the M135i. Do our learned PH'rs who tested the M135i have any final words for us. Thx to all those who contributed.
Cheers...
ps. I'm not the guy who's about to pick-up a M135i from somewhere N of Leeds...wonder if he chose RFT's

2010 BMW 123D Coupe, (with M spec suspension, which is apparently better damped than standard) came on OE 17" staggered size runflats, I changed at 1500 miles to Pilot Sort 3's. Lifted up both R/flats and Pilot's to check the weight difference and my 'arm scales' detected only minor differences.

The car may have ridden marginally better on the new Michelins but it really is too close to call.

They have progressive breakaway when they eventually let go and preferred more pressure than standard at a recent trackday, they grip harder than I'd really like on dry 'public' tarmac.

The runflats didn't exactly lack grip anyway and the car is 'overtyred' for the torque output, a drifter it is not.

I carry two cans of tyre mousse.

I'm sure this is a fast car for the money, but am I the only one who thinks it's pig ugly?

Nope. Hasn't stopped me ordering one. I reason that I sit behind the steering wheel, not out on the street gazing at it lovingly, so the fact it has a face that cracks mirrors is immaterial. Plus I do think the MSport versions aren't quite as gopping as the cooking versions.

For those not having read a write up.. this gives a good review.

Only the headlights really muck it up, the rest is inoffensive enough and quite purposeful - squint and it's got shades of BMW's Breadvan about it.

Very quick car, 0 - 150mph in 25 seconds:
