Best price and place to get ZCP wheels?

[Tbonem3]

Because Michelins run wide. Because that's not BMW spec. BMW only speccd 245 on a 8.5" for e9x and they still kept 265 for the 9.5" (on e9x). They actually specc'd 255 for the 9.5" for u.s. E46 with 19". Because albeit small, 245/275 is heavier and slower. Perhaps turn in feel isn't as crisp either.

Wider tires don't give a wider footprint. You'd need wider wheels.

235/35/19 and 265/30/19

Well I always interpreted footprint to be the contact that the car makes with the road. That is determined by tires, not wheels.

Additionally, I was not going with the factory spec sizes, which by the way are not 235/265 but 225/255 on the m3 ZCP. 235/265 were only CSL spec tire size. Many people decide run wider tire sizes on OEM wheels to get extra contact on the road.

Sorry???

Keep in mind Michelins run wide. 235/265 ps4s is perfecto on CSL/ZCP.
Unless you don't want your car to look like this:

Well true the Michelin 265s don’t look nearly as bad as their 255s. Still not what majority of BMW car writers have said about the CSL rears. They suggest 275s. From Bimmer Mag, European Car, Roundel, BMW Car and Performance BMW.
I’m very familiar with Michelins, as that’s what I run for decades. I have even run Michelin Sport 285s happily on my CSL rears. I’m running 275 now for the grip and look over the 265. And not a chance will go further and run ridiculously 255s.

You don't get more grip from 275s on your rear wheels than 265.

BMW doesn't spec a tire for "looks"

Proper tire for a 9.5" wheels is 265. Take a guess at what tire spec track rats run on their 9.5et22 square wheels?

Actually according to BMW USA on the E46 it’s 255.
275 are within specs by Michelin. I go with the tire manufacturer.

You get more grip driving.

Oh and here’s the experts at BIMMER MAG’s take on it.

Ok buddy.

i like how this super smart magazine guy chose a 40mm staggar (235/275)

For a street car, and for how 95% of people on this forum drive, it does not matter if you get 255s, 265s or 275s. Just keep a 30mm split front to rear to keep a factory like balance. Here is yet another link to confuse people even further.

I couldn't agree more, I went from a 225/255 to a 245/275, can't tell a difference as it's street driven. I just wanted the tire width for looks mainly.

Damn shame about no more CSL fronts as I would love to maintain the wide rears but wouldn't necessarily want to run a 235/275 stagger. I would think a 245 is pushing it on an 8" wheel but may be dead wrong.

Did you use 245/40, 275/35 or 245/35, 275,30 ? 19s or 18s? I ask because it seems the ratios are equal but the tire is slightly taller when using 40/35 on a 19. And I was wondering if that combo would rub up front as it seems most ppl run 35/30 when going wider.

Most important thing for a street driven car is to keep overall diameter the same front and rear. It came with 26’’ overall diameter from factory. I prefer to have 25.5’’ cause it looks better (sidewall) and it also helps acceleration. Keeping same overall diameter will get your DSC/traction control to work properly.

On my OEM CSL wheels, I had Michelin PSS 235/275 and it looked perfect. On my BBS LM 19x8.5 19x10 I have 245/275 but I prefer the look of a 235 on a 8.5’’ wheel. Just a little bit stretch.

Yesterday, a guy came to my place with an Imola ZCP and he had 245/275 on his OEM ZCP rims, 245 looks terrible on 8’’ wheels IMO…

When I shop for tires, I go on Tirerack website, choise a tires and check specs to see info like overall diameter.

245/40 and 275/35 on 18's, went from the stock 19's to that. My car has BCs on it so it does sit quite low but I'm not even close to rubbing with my current setup, I would wager the 19s w/ the same tire arrangement would be ok even.
