wheel sizes

[jnorton]

Hi

My vehicle is a C320 ( W203 ) Elegance and I wish to replace the standard wheels.

I was trying to find out what are the largest/width I can fit to the standard vehicle. I was looking at 225 50 17 for front and back, but could I go wider at the front wothout it affecting the steering or any modifications needed ? same at the back, how wide ?

Thanks

HI .
I had a similar enquiry some time ago,i was posted with a website address,which is http;//www.miata.net/garage/tirecalc/html
It gives you the rolling circumference of the tyre size that you want and how it effects your speedo.All i do know if you go bigger than the spec,it can affect your cruise control. good luck

Jason,

Best guide IMHO is below. It is possible to go slightly bigger - Brabus, BBS and others offer 8.5 fr and 9.5 rear in 18". You'd need 225/40/18 fr and 255/35/18 rear. Honestly no point in going wider unless you're prepared to do body mods.

Standard fit on my C43 are 225/45/17 front and 245/40/17 rears if that helps?
