6 Series wheel options
Discussion
Hello all,
I'm going to buy a BMW 640d '15 plate onwards, and its purpose is to transport me long distance in comfort.
I'm going to be doing 22.5k a year.
I've pretty much landed on this car, I love the interior, especially with the comfort seats.
Most of the 640d's I see have 20" runflats and I'm a bit concerned about ride quality.
On the one I've taken out recently the ride was fine, but it was a short test drive and I'm going to be sitting in it for 4hours at a time.
I'm more interested in comfort than the looks, so I don't need the 20" wheels.
Does anyone run on 17" or 18"?
What tyre code do I need for these options?
Should I pick alloys from another BMW?
Should I avoid runflats?
- I looked in the boot and BMW had located the battery was in the spare tyre well!
Are tyres going to be cheaper with smaller alloys?
Are rears wider than fronts?
Appreciate any help, I’m a 6 series newbie

My 6 had the 19" standard wheel and even with runflats, the ride was very smooth and compliant, much better than the model with 20s that I test drove. Anything smaller than 19s and your car is going to look under-wheeled imo.
ETA standard wheels on the 6 have wider rears compared to the front.

A friend of mine has a 640d and he's gone with non-runflat 19" tyres (went with Vredestein Ultrac Vorti's IIRC) and he said the car drives so much better
He does around 18-20k miles a year, knows he hasn't got a space saver, but has the genuine BMW tyre repair kit, which can be bought via eBay cheaper than the dealers. Could be worth thinking about

I have a 640d M-Sport with 19s.
The car came with run-flats and although it has about £22k of options Electronic Dampers were not one of them. I do 30k miles per year and found the ride quite harsh on RFT on A/B roads. A switch to non-runflats improved the ride massively. I have a tyre-spray-can and BMW Assist if I get a bad puncture.
Some SE models did come on 18s, but in non-staggered sizes with 245/245 instead of 245/275 as in the 19s and 20s.
I suggest that you buy the car you like, then try non-runflats before looking into smaller wheels.

Yes that's what I'm a little concerned about.
245/245 is going to be different handling to 245/275. Especially as there's a lot of power to put down on the rear, with only 245 rear that's a smaller footprint.
Unless there are 245/275 18's.
If you're doing 30k a year, what are you tyre costs?

I’ve done 30k on the tyres so far, the rears were fitted exactly one year ago today and they still have plenty of life in them, reckon they’ll last 40-50k. But that’s because the mileage has been long trips once a week of 250-350 miles on motorway/dual carriageway which hardly wears the tyres, also a trip to Italy and back.It’s just not a car that you end up driving at 100% through the twisties, it doesn’t suit it’s character, it’s a great Grand Tourer in the truest sense.

Mind if I ask what tyres? That's serious mileage out of a set of rubber!
Michelin Pilot Sport4s, so proper tyres.However it spends 90% of its life on active-cruise control at 50-75mph on motorways or dual-carriageways, so there is little braking/steering to wear the tyres.
without a shadow of a doubt in your situation 19s on non run flat tyres will be good and a must. If you want the most comfort out of them then read up on tyres that might have a softer sidewall than others. Personally I found goodyear eagle F1 tyres had a softer sidewall compared to the alternatives.
20s on run flats or even non run flats will cause you all host of issues purely on the basis they buckle and kink easily and will cause vibrations to no end in the car.
