Opinions on 295s for this setup?

Was hoping to get some opinions on whether 295s would look ok aesthetically. Hoping to get a little more traction with 295s but I am worried about ruining the look of the car.

The pictured setup is with 285s and as you can see it's already sticking out a bit from the fender. I just cant decide if going up to 295 would push it over the line from looking nice and aggressive to goofy/unproportional.

You can easily fit a 305 on a 11et42 (38-44 are common offsets). Common square track setup is 18x10.5et36 square (15 mm spacer on the front) with 295 square tires. So there are plenty of options that’ll work with a 295.

11 refers to the width of the wheel and 42 is the offset, is that correct?

I have the 20" competition wheels which I believe are 10" wide? Not sure the offset but it looks like the 1st owner has put some aggressive spacers on there which is why the current 285s are sticking out a bit from the fender.

Are people running 295s with the 20" comp wheels?
Going from 285 to 295, would it just be an additional 5mm increase in the amount that the tire sticks out from the outside of the fender?

295s are too wide on a 10in rim. You can do it and plenty of people do, but those sidewalls will bulge and not be properly supported. Minimum you should be running 10.5in and optimally a 11in rim with 295s. I've also found that BMW * spec tires usually have a very narrow tread width for the sticker'd size so a BMW 285 is more like a 275.

Correct. For example, an 18x11et42 is an 18” diameter wheel that’s 11” wide and an offset of 42.

285 is the max for a 10” wide wheel. Just because you can install a wider tire, doesn’t mean you should. There are a lot of articles proving this. Here’s one article:
https://grassrootsmotorsports.com/ar...always-better/

Not all tires for a given width are actually the same width. For a lot of 200TW tires, a 295 can be as wide as a 305 or 315 so it’s always important to check tire specs before buying. A 295 sounds like it should be 10 mm wider than a 285 but different brand have different real widths and rolling diameters. Also, an 11” rim is measured from its inner tire bead to inner tire bead mounting seats. The beads are 1/2” wide from inner to outer wheel surface so an 11” wide wheel is actually 12” wide from its outer face to outer face. This is important when using offsets to calculate the frontspacing and backspacing of wheels.

This is great info, thank you both.

I'm wondering if it would even be worth the cost of buying all new wheels just to move up from 285 to 295 in that case.. Is the traction difference noticeable?

I believe the tire compound you choose is much more impactful.

I have pilot super sports currently. Would the pilot 4s be an improvement?

Yes, it would be a noticeable difference, especially when the tires are cold and in rain.

Stepping up to 200TW tires will make a huge difference in grip even if you stuck with 265/285. However, lighter and wider forged wheels with even wider 200TW tires, especially a setup that’s < 20 mm stagger or a square setup like 285/295 or 295/305 or 295/295 have a noticeable difference in grip you can feel.

I used to run all three of these 285/305, 295/305 and 295/295 setups depending on track and rear spring rate (1100 or 1200 lbf/in rear divorced spring). A 20 mm stagger is the widest you’d want to run on track because if it’s > 20 mm it will provide too much rear grip relative to the front and, therefore, it makes it more difficult to rotate the car on corner entry. 265/305 is a great street option which has a safer limit with understeer on the street and the 305 provides more rear grip to help with putting power to the ground on the street.

You can fit 295 on a 10" rim but just be aware that you are trading away some sharpness/stability in corners for increased lateral grip (possibly) and the looks of a meatier tire. Like M3SQRD said, you can compensate for that with a stiffer tire, like Cup 2's or similar if you want, but that does come with its own tradeoffs.
