I recently bought another set of street use wheels for the M3 and decided on a staggered set from Apex, EC-7 in 9.5x19 and 10.5x19 sizes in their summer sale; also bought PS4S in same sizes (255/35, 275/35) I was previously running on the 220Ms with PSS'.
For general street driving these feel outstanding. I can tell right away the wider wheels giving a nice taught feel to the tires, especially out back where it's nice and taught in transitions. The wheels/tires feel great, are wider and significantly lighter than the 359Ms, and look good too imo (race silver). The perfect condition 220Ms are boxed and stored for now.

Glad it was helpful to you We have a full vehicle specific fitment guide on our site now, so hopefully more enthusiasts find the information useful.

I'd say it greatly depends on your ride height. I'm lowered to about ZCP height and when I ran the Maxis RC-1 in 275/35/18, I got rubbing at full lock. The 285 tires will be even taller. If you are stock height, you might be able to get away with it.

I've run the 285/35-18 on a 10 up front (RS3's) and 285/40-17 on the 17x10 ET25, and can confirm you're going to hit stuff even with stock ZCP springs
Huge mid-corner grip from the frontend though. It rubs a lot when the tires are new and gets better as they wear down a bit, back of the fender liner up front will have holes in a few hundred miles

I was getting some rub on 275/35/18 up front on 9.5” 219s until Malek did my alignment last. I’m on stock ZCP otherwise.

I highly suggest purchasing adjustable camber plates, not only to ensure you do not rub the front fenders, but more importantly for more consistent tire wear and mid corner grip. You'll want to leverage that new wheel and tire package. If you are going to upgrade to coilovers in the near future, than you will want to hold off on camber plates to do it all at once (camber plates built for the OE spring diameter will not work with 2.25", 2.5" or 60mm linear springs commonly found on most track oriented coilovers). In the interim you could pull the camber pins which will at least net you somewhere around -1.8 degrees. - Ryan

Given your 10.5" ET25 wheel specification, your best bet would be a set of 5mm spacers (effective offset of ET20) with most suspension designs including JRZ, MCS, Ground Control, TC Kline to name a few. 3mm spacers could also work, but it is better to error on the side of caution if you have both spacer options available to you. Tires deflect under load, and you may go with a wider compound in the future so a few extra mm of strut clearance is worth it. Now you are currently running OEM suspension (with lowering springs), which takes up a little more room than the suspensions mentioned above, so you will definitely need a minimum of 5mm spacers to clear, and even with them it is going to be quite close. Since you will be in the market for suspension soon, note that KW, Bilstein and Ohlins to name a few are not as friendly to wide wheel and tire fitments, actually taking up more room. In this scenario that results in the need for thicker spacers. Thicker spacers result in pushing the wheels further out towards the front fenders, which in turn requires more negative camber to prevent rubbing. It is very much a cause and effect relationship. The bottom line is 18x10.5" wheels up front are best suited on a car equipped with proper suspension including adjustable camber plates, and one could argue that if you are the type of enthusiast looking for the marginal gain/benefit of 10.5" wheel over the common 10" wheel, you should have suspension addressed. I hope that makes sense. Suspension is a whole other topic, but as you can see from above, it is important to consider how a potential suspensions will effect front wheel/tire clearance - something often overlooked. It is a slippery slope isn't it Give me a shout anytime if you would like to discuss further. - Ryan

I can fit the 10.5 Titan7's with 275 tires up front fairly comfortably (depending on tire brand) but I run -3.5* camber and have JRZ RS2 coils which have more clearance than stock. I currently have my 18x10 ET25 ARC8's on my car with 265/35/18 tires. I have about 15mm of clearance on the outside. A 10.5" wheel would would push the sidewall out another couple of mm, then add another ~10mm on each side for the difference between a 265 and 285 tire and now I'd have about 3mm left. Not enough room for a 5mm spacer and I'm at -3.5* camber. So, I highly doubt you'll fit a 285 tire up front with < 2* camber regardless of what spacer you run. You are going to start running out of room on the outside. Best thing for you to do is to mount some tires on your Titan7 wheels, and do some measurements. Or measure your clearance with whatever wheels/tires are on your car now and do some calculations. |

There's room to run a 285/30-18 all day long on a 10.5, so let's be careful about which tire size we're talking about. The 285/35 is a bit tall and wide for a 10.5 I agree, but I think it's doable, if you don't mind some rubbing. I think the hottest street tire/wheel setup you can get on one of these cars, if NA, is the 285/30-18 RE71R on a 10.5, square. You get a gearing bump, you get the fastest 200tw tire, and you maximize the amount of tire you can get on the car up front where it needs it most. IF you're supercharged that's not a whole lot of rear tire to take all that extra oomph So... to sum up - take it from me, who has done it, don't bother cramming the 285/35-18 up front, it can be done, it works fine, but why when 275/35-18 and 285/30-18 tires exist?

I was planning on running Titan 7 TS5 18x10et25 275/35 in front and 18x10.5et25 285/35 in the rear in stock suspension. I think I'm good, hopefully. Do I need to pull the alignment pins?
