yes, and yes

What suspension is that on? Back tires look stretched, curious to see what 275 looks like.

Or what about wider 265 vs a 275? Just don't like stretched look, and plan on having a modest-Eibach type drop.

? or more specifically, do you know if it will rub? im lowered as well.

Here is my set up on stock hight.

f19x9 et35 245/35/19
r19x10 et38 285/30/19

Bridgestone Potenza S-04 Pole Position

Not a fan of stretch look, so I went with these wide sizes.

Rears rub at some dips on the highway, so I am getting the fenders rolled tomorrow. Hopefully it will stop rubbing.

Front did rub at left steer 2/3s of to lock. It was the bottom right nut of the oilcooler vent grill on the right fender liner. I took it of for now and no rubbing. I've seen on a forum here that someone did the same thing and going on the second year with no problem. But I am thinking about somehow pushing the liner to front or sanding down the vent grill and putting it back on there.

Anyway, it is a working project right now. I have to say though, I love the look of the car with the wider tires.

Okay, I got better sized pictures here.

those look fantastic. im surprised you actually got 285 with thicker wall tire like those to fit. the non stretch looks makes a big difference

Wow, 285

I wonder if you'd still rub in 275? You're on stock sport suspension?

My main goal was avoiding stretch look, and same side wall hight for front and back. After lots of calculations I knew that 285s were going to fit just fine, I just didn't know how much to rub going over dips???

Here is how I started:

Originally I had 265/35/18s with factory wheels at 37 offset and 12mm spacers, which gave me a pretty flush look at ET25. So the distance from the center of the wheel to the hub is 25mm. This means center of the tire to the hub is also 25mm. Width of the tire is 265mm, So from the center of the tire to the outer edge of the tire would be 265/2=~133mm. 133mm-et25=108mm is the distance from the hub to the outer edge of the tire. So 108MM is the key number here.

Lets do the same thing for the new wheels and tires I was working on getting:

285/30/19s with et38 wheels (No Spacers this time). 285mm is the width of the tire, so 285/2=~143mm is center to outer edge of the tire. 143-et38=105mm is hub to outer edge of the tire.

As a result I knew the new tires were going to sit (108mm-105mm=) 3mm further away from the fenders compared to the old tires.

Now I had to compare the hight of the tires:
265/35/18s 643mm tall, and 285/30/19s 656mm tall
So the new tires were going to be (656-643=)13mm taller than the old ones. Which means I would have 13/2=6.5mm more tire tacking under the fender.

Here we go: Outer top corner of the new tires would be placed 3mm inner, but 6.5mm higher under the fender compared to the old tires.

With these numbers I went to my car and measured the room I have in there.
YESSS! I knew that 285s were fitting!!! Rubbing was possible but that was my next project to work on.

Finally this past monday, I got the fenders rolled and gained maybe another 3 to 5mm room under the fenders. Now, NO RUBBING at all. I tried dips at 90mph and no rubbing! Thankfully I won't have to deal with adding neg camber.

So yes, it was quite a process for me to fit all this rubber; sometimes I even thought I was gambling with high priced tires! What if it didn't fit??...

Anyway, let me know if you have any questions about my calculation. It worked for me. If you haven't bought your tire and wheels yet, give me your current set up. I'll put some numbers together we'll see what would fit or not...

Yes, I am on stock suspension, and I think 275 would have been an easy fit. However, I think front and rear side walls should match.

245/35/19 would give 245x35%=85.75mm side wall
285/30/19 would give 285x30%=85.50mm side wall almost equal

275/30/19 would give only 275x30%=82.5mm side wall which would be 3mm shorter than the fronts. Most people wouldn't even notice but just knowing it would have bugged me. So I pushed harder to be able to fit the 285s in there.

Hi Ivan, this is Hamit. Thank you for these amazing wheels, they turned out pretty good looking even on stock hight on my car. Quick question on this white e92, are there wheel spacers on the rears or the LCIs run wider?

The E92 is lowered on ST V1 coilovers with 235/35/19 , 265/30/19

No spacer on this car as I know.

Ya, plus each tire has two sidewalls (top,bottom) 2.5mm x 2 is 5mm. However that is mm vs inch. That's like 2 tenths of an inch. Not really going to be noticeable from front to back but I get it.

Another quick way to compare tire's and offset is tiresize.com for comparison and offset. You can also look at the plus and minus tire sizes that fit your vehicle at discounttire.com
