I've got a 2003 mk1 Ford Ka Style, 1.3 l. It's currently using tyres sized 165/65/R13 which, in my opinion, are really too thin. Looking around I've seen that it can also mount tyres sized 195/45/R15, which seem to be a popular choice combined with alloy wheels. I couldn't care less about alloy wheels, all I'm interested in is using thicker tyres.
Will them make any difference in term of stability? Will I be able to fit them with normal steel wheels? Thank you.
Edit: I'm trying to get the best reliability in wet conditions, that's what I mean by stability. Sorry about the confusion.
