Winter wheel/tyre dilemma

Post by Temeraire » Wed Aug 29, 2018 12:32 pm

I currently have an 2016 M135i with the standard 436M (I think!) wheels.

I want to get a second set of wheels to run winter tyres on. 18" Style 386s seem to be available at reasonable price, I assume
they'll fit the car? Sizes seem to be 7.5J front and 8J rear.

On the subject of tyre sizes the fronts seem pretty straight forward. 225/40/18. What size should the rears be please? 245/35/18
look to be rare and expensive in winter tyres. Could I run a smaller tyre on an 8J wheel? Like 225/40/18?

Any help with the above would be appreciated - it's a minefield!

Check out this table kindly provided by marco_polo in second post on this thread.

Looks like it is an acceptable fit but whether its a good idea on a M135i I couldnt say.
Im sure other folk will offer advice soon.

Toyo Snowprox S 954 are now available for a sensible price in 245/35/18. Up until the Toyo's were released, most people ran 235/40/18 on the back.

There is a school of thought that says 'Just go with what BMW recommend as a winter wheel+tyre spec' On my M235i this is a 7.5Jx17 225/45-17 and that's what I've gone for (down from a 245/35-18 summer size on 8Jx18).

My logic ( and I know it's not everyone's) is that I just have to accept that a M-Lite in winter is not going to enjoy the same levels of grip as in summer and no amount of rubber can compensate for that difference. So I might as well go for reduced aquaplaning and use the 225s which will disperse standing water and heay rain better than anything wider. In the dryer/warmer months, yes I'd prefer to be on wider rubber but then I'd prefer to be on summers after a certain point.

It's not black-and-white and there's no right or wrong answer to my mind. But if you're buying new wheels and tyres, then you do have the choice of biasing your winter setup to reduce aquaplaning significantly, rather than trying to reprise a summer setup that can't deliver summer traction. Just a thought.

I’ve been doing some research and planning on this topic lately and I think I’ve decided to go with 225/40/18 Michelin CrossClimate+ front and rear.

I’ve been using winter tyres for years across various rwd cars and I consider them a necessity, but, I really don’t like the softness they tend to introduce to the handling with the many tall, soft tread blocks. I’m also mindful that we have an awful lot of dry and damp days through our winter months and would prefer a tyre that excels in those conditions and copes in the 5 days of snow rather than vice versa.

The reviews on the CrossClimates look very good, seemingly designed to do exactly what I’m looong for.

Size-wise, yes a narrower rear may limit me a touch getting on the power, but I don’t expect much of a difference elsewhere and the benefits are that I can switch front and rear to even out wear and it should be a little better in low grip situations.

My thoughts anyhow :thumbs:

On my M135i, I ran 225/40/18 winter tyres all round on staggered 7.5"/8" widths on OEM style 385's initially then 461m latterly. No issues whatsever.

If in the market for a set of VGC 461m - I still have wheels only so PM if you want to buy them off me - photos below of actual wheels on the car

I am also considering all round 225 40 18 Cross Climates for winter. I dont need full snow performance, just need to be able to get home. I managed to get home from work last year even with MPSS....just. I just think for my needs and for our mild winters the Cross Climates will perform better than a full winter most of the time especially in the dry. I would like to know which performs better whens its wet and cold/greasy as this is a common condition and where the m240i struggled the most on MPSS tyres. Hell I even struggled in the dry when it was cold. The full winter option I am considering is the Conti Wintercontact TS850P and would likely go a wider 235 40 18 on the rears. I left a message on tyre reviews and they replied saying they would probably lean towards the Cross Climates......but the Conti 850P is an incredible tyre. Decisions decisions.
