I have just bought a set of used oem 19"alloys (172s). so now i ll be changing my mv135 18" which had run flat tyres with these new wheels. so what i wanna know is that which spare wheel should i get, as most of you would know that 172s come with wider rears so should i get a wider spare wheel or normal front wheel plus i need some info about the tyres as well as the 172s i have bought are without tyres so i ll have to buy new tyres and dont wanna splash out much so please advise me on good cheap tyres or any suggestion about used tyre. as always your help is highly appreciated.

For the spare, get the regular "doughnut" and don't bother with the full-size spare. If you REALLY want to, get the narrower (front) one - just for practical reasons - cheaper tire.

As for a good tire, Hankook Ventus V12 is considered to be the best summer tire.

Get the space-saver steel spare which comes with the 19"172M option.If you buy a spare 19" alloy it will take up some boot space.Don't forget to buy a wheel change kit (jack,etc) also.As you are in the UK you will need all-season tyres, the Continentals on the 172M's will not be cheap,but I'm sure others can give you advice on alternatives.

just get a donut!

Glazed or otherwise ... a full size tire will eat up too much trunk space!

I done exactly the same swap as you not too long ago. I got Falkens on my 172s and am very happy with them. I also got the space saver wheel from the dealer for ?150. It also comes with the jack and other bits.

thanks jas. thats what i was thinking to go for falken as a lot of e60 owners in the US use them as well. any specific falken jas or anyone and what sort of weather for ?
