I live in the the UK and I am now considering buying a new set of wheels and winter tyres for my R172 as I am worried about getting to and from work safely in cold/wet weather. I have looked on the Mytyres website and I am wondering about Bridgestone Blizzaks 225/45 R17 with the most basic wheels. On the Mytyres website it mentions an option for the complete wheels to be ready installed with a TPMS sensor (£185 for this option). To be honest I am not really sure what this is but my datacard shows that my SLK has a Tyre Pressure Monitor (Code 475). I would appreciate it if anyone could confirm if I will definitely require the wheels to have this sensor. (Is there a sensor in each wheel?). I live in Kent and I will probably look for a mobile fitter to change the tyres over for me. Any advice would be appreciated.
Thanks,
Sharon

Keep in mind that winter tyres need to operate at 7c or below. Above that ambient temperature, they wear very quickly. Last winter in the SE, the temp very rarely dipped into that region, and when it did it was short-lived.

To answer your question, yes, you should opt for the sensors - one in each wheel. And make sure the supplier guarantees the sensors will hook up to the Mercedes frequency.

You can run without them, but if you do, there will be an annoying message flashed up in your info screen that the 'pressures cannot be read' every 5kms or so. The message is easily cancelled by pressing the 'OK' button, but it becomes a nuisance.

not starting a row

but modern winter rubbers are very durable. so you'd probably be ok with them over the 3 or 4 months we call winter, even in the balmy south east.

have you considered an all season like the Conti extreme DWS? maybe your driving style you want summer performance tires in the better weather.

Thanks for the information re the Tyre Pressure sensor. It makes sense now.

I'd save your money to be honest ..

I've never bothered with winter tyres in the UK, even during some of the more recent colder ones with lots of snow ...

The previous car (front wheel drive 3ltr Alfa) and the 55 haven't suffered on normal tyres ....
