17 inch winter tyres

[ppavuk]

Temporary fitted wheels with 225\45 winter rubber as sending my oem 18" to refurbishing. Ride is much softer, but almost no grip. DSC engages on every second roundabout, and on very hard braking front axle slip and squeak ever before abs engages! Accidentally did the noisy braking trick on country just in front of police car (they were just over crossroad). They turned over and followed me for 5 miles or so. Never ever before was I so good and polite driver! Didn't stopped me though

Will perhaps keep those wheels for winter time, but at summertime no good they are! Can't wait my oem 18" to be done!

Btw, alloys are ET35, so track is a bit wider, but does not feels as stable as on OEM wheels. I am not sure really, I maybe even sell them or swap to 18" winter kit...

They perhaps will fit Z3 nicely, but no good for Z4 with ///M suspension! Just in case - picture below, still plenty of thread! Or even better i'd consider 18 OEM\Replica with no rubber \ crap rubber for swap.

Grip on winter tyres reduces dramatically above 7 degrees. In this heat they will be really struggling I would expect. Just take it easy in the heat, give yourself plenty of thinking and braking time. If you were to have a prang your insurance will look very closely as to why you've got winters on in the summer and very likely put you at 50% to blame irrespective of the circumstances.

@hard top ran his Z3 on winters all year round he said, I know several people who have also done that without detrimental effect. Not saying it's a good idea just that there's maybe another reason why they're so poor. Pressures maybe?

As Tony says, no problems what so ever, never got mentioned at MOT time ether.

Insurance don't care, as tyres isn't counted as mod AFAIK.

handling and braking isn't that bad to cause any issue, even more with this set I feel safer for my rear end
Now it's brakes as brand new fiesta, or even better

btw, avail for swap - if anyone get ready to swap genuine stuff for this

they ain't that bad, went for shopping with my Mrs, and she didn't noticed a change I've tried hard to convince her why I have to swap those back to original, and she agreed that oem looks far better, so money box exposed

The clue about winter tyres is in the name. We would all be using them all year round if they matched the performance and wear of standard tyres. The MOT doesn't as far as I know(which might be wrong) look at the type of tyre only its condition when presented.

Many tyres grip and handling starts to reduce below 4mm.
Winters use a different compound and construction with silicon that aids grip in cold, snow and wet conditions. Run them hot they won't necessarily perform the same as standard tyres in the same condition. Why would you expect them to.

Many Insurers start to load any claim against you if your tyres are below 3mm - well above the legal minimum.

A few years ago insurers were refusing claims if you winters on even in winter if you hadn't told them. They will try any argument to reduce their liability that they can. I suggest using common practice as an argument may not work.

So, all I'm saying is by all means use winters in summer (many do without issues), but, don't expect the same grip & performance (you're reducing your margins potentially especially if well worn), wear or complete cover from your insurance.
Your tyres are what stop you getting the grey and green stuff mixed up. Pays your money take you choice.

I totally agree with you - I've put those only temporary to get car running this week while my oem alloys are in workshop. Unlikely I even do a 100 miles on those winters. Once my normal wheels back I'll get them straight on and leave winters for winter!

Also, the handling isn't that bad - I believe 98% of cars on the roads handles and grips far worst than Z4 even on winters at hot summer day

t-tony was right, pressure it was, all four 22psi. Get it to 34/32 rear/front and back to normality!

Who would pump Z4 wheels to 22 psi?
