Thanks and let us know

Really appreciate the time the OP took to figure all this out.
Thanks for these photos. Anxious to hear how the new wheels and tires are working for you.

Hey thanks those look great!


Question: Do the rims stick out any further than the tires? I ended up with some semi convex wheels for my winter set and the spokes sticking out further than the tires makes for real easy curb damage. I would like a slightly concave wheel or at least one that does not stick out further than the tire

et 43 looks like the perfect square set up for PS4

Thanks again to XutvJet (OP) for his post. Super helpful and much appreciated.

Test fit my OZ Leggera 18x8 et 45 wheels with 245 width Michelin PS4 tires all around.

In the front, there is very little room between the strut and tire. I tried adding 5mm spacers, but this moved the tires out to almost even with the outer fenders. Some might like that look, but I like the tire to be inset a little at the top. Et 43 is appears to be the perfect offset for 245 width PS4s. I encountered no rubbing with the et 45 and no spacers. Did full lock circles in both directions. There would be an extra safety margin at et 43.

In the rear, the et 45 works great with loads of room. It sits further to the outside than the stock et 52 wheels. The rear would probably work well with the 5mm spacers to get to et 40.

With the Alutec Drive wheels and MPS4 tires, the tire sidewall protrudes past the wheel lip ~1/4". It's a very square and blocky look. If you've got the factory staggered setup with MPSS 245/35 in the back, that's the look and protection at all four corners with my Alutec and 245 square setup.

Great description of the look.

Factory fronts for the M235 & 240is is typically a 225mm width tire on an 7.5" width wheel: so 8.86" tire on a 7.5" wheel. With XutvJet's set up, one has a 9.65" tire on a 8.0" wheel.

Thanks for the great info, both of you.I am getting close to getting a new setup.

Do either of you think that a 245/40/18 would work as well? The only difference is 1 inch in height difference. When I feel the space between the stock front tire and the strut height does not seem to be an issue.

I am considering the VMR 804 which is 18 x 8 with a 42mm offset.

Looking to get a more meaty setup with more sidewall for ride/potholes.

Thanks

Probably too tall. There is an excellent alternative, however. A 42 offset with 245s should be excellent for a square set up.

To get more "meat," consider a 17" wheel. 245/40/17 would be almost an identical diameter. I have run 17s on my M135i and then my M235i. The 17s should perform at least as well if not better than the 18s and be less vulnerable to both potholes and curbs.

I have considered 17't but have not found a wheel I like and is lightweight.

What do you think it would hit/rub on being taller?

While pricey, these wheels are forged, extremely light and very strong. Available in 17s to fit over the standard M240i blue brakes. You can customize the offsets and center bore. Many finish choices.

This style may be a little closer to the VMR 804s:

I wouldn't. A 1" difference in diameter is pretty massive and will make the wheel look smaller. I imagine there will be some rubbing on the fender plastics too. You'll also lose some gearing with a taller tire.

Yes, indeed. If you want more tire "meat," get the 17s at essentially the identical diameter.

While those look like great wheels I really do not want to spend that much.

The difference is just under 1" in diameter, which would equal less than 1/2" on the top and bottom. This would only raise the ride height 1/2" and bring the tire 1/2" taller. I don't think the difference is huge. The tread width and section width remain the same as the 35 series.

Those look pretty good! I don't know that a 9" wheel is what I am looking for though. I don't like the rim sticking out further than the tire, and I think you would need at least a 255 or 265 to fit that way on a 9" rim. I don't think I could fit that with all stock suspension, which I intend to keep.

experiment

FastEddy1: This is an interesting perspective: "The difference is just under 1" in diameter, which would equal less than 1/2" on the top and bottom. This would only raise the ride height 1/2" and bring the tire 1/2" taller. I don't think the difference is huge. The tread width and section width remain the same as the 35 series."

Please let us know if you go forward with the 35 series on the 18" wheels. It would be fascinating to see how this works.

XutvJet's experiment on the 245 square set up has benefited a number of us. The vehicle should probably come from the factory with this configuration.

The section width of a 245/40-17 Michelin Pilot Sport 4S is 9.8" and the measured rim width is 8.5", so I don't know that you'd have that wheel-wider-than-the-tire look.

A 255 Continental ExtremeContact Sport in 255/40-17 might look better with its 10.2" section width, though. I don't know if there are any 265s in 17" - the Rack doesn't show any in 30, 35, or 40 series.

I don't know if you noticed on that page, but Bimmreworld is doing that same forged race wheel in 17X8½ ET 40 for $390/ea. The 245 PS4S would fit that wheel as well.

I think you'll be surprised in just how much taller and unsporting the sidewall will look being 1/2" taller. That increase in height will likely cause plastic fender well rubbing as well.

17s are the way to go if you want more sidewall. The issue will be that they'll look small. The 2 series has a way of making 18s look small. The key is getting rims that pull the spokes to the outside rim edge. My Alutec Drives do this and it makes them look nearly like 19s and much larger than the stock 18s.

Lastly, tire design is key. Summer tires are a must has they'll have a blockier, more squared off shoulder. All season and less aggressive tires have a more rounded shoulder and it really can dumb down the look.

Here is a comparison of the same BBS wheel in a pattern similar to the VMR in 245/35/18 (top) and 245/40/17 (bottom). The 17s only come in a 7.5" width (I think) which is too narrow. A 9" width is too wide for the front.

I really like your wheels and may end up with some. The only thing holding me back on the Alutec is there is no weight savings, and they are not currently available.

Good comparison. This make me understand I really like the look of the 18's over the 17's. I just need to decide if I want to take the gamble of needed to roll the fenders and deal with possible inner fender rubbing or not.
