help with rims - 18's on W204
 

So i found some rims on http://www.replicawheelscanada.com/
Under "M Benz" fitment

they have the MB52 style similar to that of a C63.

Anyways the offset says 43, would that work on the W204?

I currently have the stock 17's (sport), staggered setup. What do i take into consideration before buying these? also what is a good size tire to go with these rims (assume, my ride is at stock height), i did try searching and looks like a lot of ppl are going for 19's so some help would be appreciated.

In all honesty diameter, offsets, staggered, etc just confuses me!

Minimum offset is 40 and bolt pattern is 5x112. Yes they will fit but they don't offer staggered fitment. Are you planning on using same size all around?
The Audi and VW sections also have rims that will fit.

apparently they can get staggered fitment.
What about tire size on them?

225/40/18 front
255/35/18 rear

would that be proper?

here use this to calculate the offset. http://www.1010tires.com/WheelOffsetCalculator.asp

The stock C63 wheel is 18x8 , but not sure about the offset. once you find the offset just plug it in to calculate the spaces

damn, they have the monoblock s replicas i was looking for. but it only comes in 1 size, and they have no email address!

i deal with tires23.com and they can get anything from that site
it's Canadian (for once) and is near where i live

so my stock tire sizes are
225/45-17 (front)
245/40-17 (rear)

if I go with a 18" rim, would the following be the best size tires?
225/40-18 (front)
255/35-18 (rear)

or should i go 245/35-18 (rear)

?

Try http://www.miata.net/garage/tirecalc.html

It shows that the 245/35 would be closest match to your stock tires. That said, the OE tires on 18's for our car is the 255/35. I would probably lean towards 255/35 myself, maybe even 265/30 if the rears are 9" wide like the OE C63 rims are.

Regarding the front tires, you could also consider 235/40 with an 8" rim. That is the OE size for the C63 as well.
