Okay... I'm trying to get the maximum dry grip for my E92 M3 so I'd like to mount a 295 tire on my stock zcp (I know 295 is a bit big for the 10" wheel but I'm okay with that for now).

I've read a lot of threads where people have mounted 295 tires on the zcp wheel with little to no rubbing (depending on tire selection we'll get to that next).

I'm looking for some feedback on fitting a 295/zcp wheel when the car is lowered on a set of swift spec R springs (0.75" drop)? Will this setup rub badly, rub a bit over large bumps, or not rub at all?

I know tire selection plays a big part in this so I'm debating between the following in order of preference:

1. R888's - 295/30/19
2. AD08R - 295/30/19
3. PSS's - 295/30/19

I've been on tire rack and chatted with a few reps and they tell me that the PSS's are the widest of the 3 options and the R888's would be the narrowest. I've always thought the AD08R's would be the widest out of the bunch? Can someone with first hand experience with these tires please confirm the order from narrowest to widest?

Anyway, any insight would be greatly appreciated!

I'm wondering the same...

Since no one has any thoughts on this I'm going to attempt the ad08r's in either 265 or 275 front and 295 rear. Every wheel and tire shop I've spoken to say the ad08rs are a much better choice for street driving. I might also try an 18" setup with bfgoodrich rivals in 275/35/18 in the front and 295/35/18 rear.

To bump my old thread I finally got around to installing the AD08R's on the car... At this point (a few hrs of driving) I'm happy to say I haven't experienced any rubbing front or rear. I will give my impressions once I've had a chance to put them through their paces which might take awhile as it's cool and wet up here.

wheel/suspension setup:

Front stock ZCP (19X9) - AD08R 265/30/19 (I may have been able to go 275 front)
Rear stock ZCP (19X10) - AD08R 295/30/19

With swift spec-R lowering springs

Edit: Crappy iPhone pics after install on a rainy day but you'll get an idea of how it looks.

Reviving an old thread.

81bear how has this setup treated you? I have the same tire size setup 265/295 Michelin PS4S and was thinking of putting Swift spec R springs on the car.

It's been awhile but I don't remember having much issue with this setup. If I remember correctly there was a bit of rubbing at full-lock.
