Changing Winter Tires

I am trying to change my tires to winter ones.
The previous owner of the car gave me the winter tires.
However, the threads are uneven, one pair is quite a bit thicker than the other.
Since the car is a RWD, I think I should put the pair with thicker thread in the back, right?
Also, how do you tell which direction the wheel should spin (i.e. which one is left or right)?
Is there a marking on the tire?
I tried looking for it yesterday but couldn't find it.
BTW, the threads are not symmetric.

TIA for your advise.

As you dont know the basics, do you know how to change the wheel?? - you keep mentioning tyres... what do you have.. tyres only or wheels with tyres?

do you know how much torque the wheels nuts/bolts should have and how to?

for direction there will be an arrow on 1 side of the tyre if required

if in doubt just take it to a garage - its not expensive

Re: Changing Winter Tires

Asymetric treads can be be swapped axle for axle - nut not side to side. You can also get directional tyres - so double check that.

Generally if winter tyres are below 3mm - bin them and get some new ones.

Theoretically whatever drive you have - the best tyres should be on the front. Not gaining traction can be solved with chains - not being able to steer/brake efficiently is usually solved by a tree.

The former is usually a cheaper option.

I was being generous - I'd not both putting on winters unless there was 5mm - but I'm a sucker for paying money to ensure that the people who drive in my car (and myself) are safe

I have the tires + rims (i.e. full wheels).

hmm.. I don't know about the torque thing.
I had changed wheels before when I got a flat a while back.
I just tighten the bolt as best as I could.

Perhaps it is best to let a garage swap them.

Re: Changing Winter Tires

on the side of the tyre it will say if there is a direction of rotation - it may be an arow with direction or will just say left / right.

regarding the torque, frind of mine would tighten them also as much as he could, until the stud snapped and he had to get the garage to replace it at a cost of £250

Every car has a different torque setting for the wheel nuts but I never saw a garage look up the correct setting & then change setting on the torque wrench before tackling wheel nuts so I guess it is not so important to have it correct

It's a good reason to change them yourself. I have a metre long length of steel tubing at home to fit over the wrench so I can loosen the wheel nuts after the car has gone in for a service before tightening them without the tubing.

That way I know I can undo them with the wrench that comes with the car if I get a puncture in the middle of nowhere.

Re: Changing Winter Tires

With all season tires, you wouldn't have to go through all that hassle. Just sayin'

thats because the knuckle dragger has done the nuts/bolts up with the air impact gun - its quicker

If you do it yourself, tighten the bolts up, but don't go beserk, go for a drive of a few kms, then check/tighten them again. You'll quite often find one loose one.

A good pull is usually enough (ooherr missus) but never use your foot.
You use your foot for undoing them

Or not -

There is also a TCS spider diagram (although I can't find it at the moment) which shows just how bad the all season tires are compared to swapping between summer and winter ones.

As I have said numerous times before, the contact patch of rubber to road is the only thing keeping you going in the right direction. Choosing to save a few CHF by not having the appropriate tyre for the conditions is a personal choice. I choose to have good quality tyres fitted to all my cars - with a good tread depth - and the right tyre for the season.

Presuming you mean 'tread' not 'thread' (which would be the screw thread on the bolts).
You don't need to worry about different tread depths, as long there's enough and you match the pairs.
I'd actually tend to put the deeper treaded ones on the front, as steering and braking are much more important than acceleration.
Although some tyres have a specified direction of travel, many do not. If there's no arrow on the tyrewall it doesn't matter.

Yes it can: some tyres have 'Outside' or 'Inside' written on the side wall. However, as these are usually mounted on the rims by a tyre fitter you shouldn't have to worry.

Is there a specific date in CH when (before) you HAVE to put winter tyres?

No. But if you have an accident and the insurance company/Police believe that inappropriate car tyres was a contributing factor then you may be in more trouble legally and financially than if you had winter tyres fitted.

Considering it was only 4'C on Saturday, now would be a good time.

Re: Changing Winter Tires

I drive to the UK in 2 weeks - I suspect I'll be on winter rubber by then.

If you're doing it yourself, now, before it gets too cold.
If you'll go to a garage, before everyone else heads there to have it done.
So, in either case, do it now.
