w124 rims

Other day i bought only two rims AMG 18x8 monoblocks

i hope that i'll find other two. One month gone no success

I am thinking placing those on front and drive around with only two alloy rims as i can not wait any longer to put them on. I am just thinking is 225 40 r18 best tyre size for those rims on my car so even when i lower it later i don't want any rubbing? Would 18x9 be ok at the back or i should be looking for 18x8 at the back as well.

Thanks heaps guys

225/40R18 gives the correct outside tire diameter (25 inches) so your speedo and gears act stock.

Yeah, ouside tire diameter (nominal inflation) is:

<width> X <aspect ratio> X 2 + <wheel diameter>

in your case :
225 X 0.40 X 2 = 180mm = 7.07 inches + 18 = 25.07 inches (close enough).

stock:
195 X 0.65 X 2 = 253.5mm = 9.98 inches + 15 = 24.98 inches (call it 25)

my car:
225 X 0.45 X 2 = 202.5mm = 7.97 inches + 17 = 24.97 inches (perfect)

So yeah, the width doesn't effect the outside tire dimension but, is used to calculate it from the numbers they give you about the tire.
