Can you tell me why it's not optimal?

Will there be a noticeable decrease in performance when I make the drop from 205's to 195's? Or will it feel better because it's "optimal"?

Thanks.

Buying better performing tires will far outweigh the difference in width.

Probably a 205/45 tire.

25-30mm front spacer right off the bat. Tire size is good.

[Mystikal]

will it be safe to try as it is or should i get spacers? if so, what size for the front? rear?
thanks

15mm front and rear, 205/50 tires. It'll look much better too.

[Mystikal]

I have them laying around my garage and I would like to get my car off jackstands as I sold my m systems. ..

So ill be needing 15mm spacers to clear the strut? ... test fitting it seemed like it cleared but very close to the strut for the tire

.... what would be an optimal tire size?

They should just barely clear the struts with a 205 tire (reader note that E30 M3 suspension geometry is slightly different from 4-lug, this setup wouldn't work on a 4-lugger).

205/55 is optimal without spacers. If you step up to 15mm spacers all around then 225/50 with a rear roll would be nice.

Okay, heres a tough one for ya. Right now im 15x7 et20 with 205/50's. I could not be happier with my fitment, its perfect. Its e36 5 lug stuff. I have a set of e46 16" steelies that I want to get widened and get the exact same fitment. How wide would I get them made? Hopefully you can help, thanks!

I poke a smidge in the front and tuck a smidge in the back.

16x8 +35 all around will be virtually the same (within 2mm). 1" widened on the outside lip.

[Jafxod]

Then I guess run 215/45's?

[Jafxod]

Thanks a bunch man. Any idea how much that would cost?

[Jafxod]

Does 15x7 et sounds like it should be dead flush on my car. I might have to measure that by hand. This is what the steelies looked like on my car unwidened.

[Mystikal]

215/45, and no not really flush. I'd suggest stepping up to 16x8.5 +28 and 16x9 +21 for flush with 205/45 tires and rolled arches. Cost varies a lot for steelie widening, wouldn't hurt to shop around ($50-200 per wheel I've seen).

Hopefully not repeating an already answered questioned. I search the thread and didn't see a definite answer.

Looking to order the Tire Rack TR motorsports C1 wheels and some new tires. Debating between a 7in wheel with +25 offset and an 8in wheel with +20. Lowered on Bilstein sports and H&R springs. I'd like to do an 8in wheel with some nice wide tires. They recommend 225/50 but also say it will require fending rolling. Not opposed to that, but don't have the tools or know any one. Or may get the 8's but with a 205/55 tire.

So, I guess my question is. Will a 225/50/15 on an 8in wheel with +20 offset fit without rubbing badly with my suspension and unrolled fenders?
Car is a 91 318is.

Hey all, im on stock bottle caps w 195/65/14 and I really like the height of my sidewall. Im looking at a set of 15*7.5 et 25, they come with 195/44.
I checked and think those are too narrow and short. Can someone suggest a tire size to look for, so I can pruce out new tires.
Thanks, also no need for stretch I want wide tires. Thanks

Even with the 205/55 it will be very close to rubbing an unrolled fender. I'd still suggest going for it.

225/50 with a fender roll. 205/55 otherwise.
