Is a 10mm spacer a lot and safe

No and yes.

Hmm well I plan on doing quite a bit of auto-x and hopefully a couple HPDE's this summer so I want some decent tires. It seems that for 16's the widest you can get for an extreme performance summer tire is 225mm and always with a 50 percent aspect ratio.

I'm a noob to tire fitment. How much of a problem would the scrubbing be if I was doing auto-x? I mean I'd be using a lot of steering lock and what not.

I guess my other option is to run Kumho Ecsta XS's or Falken Azenis RT-615k's since they're available in 215 45 r16.

If you're willing, knocking a few key dents into the front fender wells will get rid of most of it. I don't think you'll ever be 100% successful though.

Okay this same setup but I bought some 15x7 Enkie 92 reps. I had to choose offset 0 or 20. I knew 0 would poke and Im not planning on stretching tires becuase that would be dumb on 7 wide, so I got offset 20. As for tires Im thinking 205/50/15, ive run this size on 15x8's with a hair of stretch so this should look normal. I do have rolled fenders and theres a good chance im gonna wanna run spacers to get sortaflush, i was thinking 10's or 15's, thoughts?

Should be space for 10mm front 15mm rear with rolled fenders.

Wheels are 7x15 ET35
Car is 1989 325i

Can I put 225 width tires on the back and 215 on the front?
What about sidewall? Should I get the smallest sidewall possible or the thickest?
How about 40 or 50 for the sidewall?
Car is just used as a daily driver for now.

You could, but why? These cars need as much front tire as possible IMO, and there's quite a bit more tire clearance in the front anyway. You'll also need 10-15mm spacers to fit those wheels/tires.

You also want to keep the tires as close to 24" as possible. 215/50 225/50.

17x8 et25 with a 245/40/17 tire? Or do I have to run a 235/40/17?

It'll come down to the exact tire model used. Some will clear, some won't (section width and rim protectors vary).

ive got some 17x8 apex arc-8s with 215/40/17 yokohama parada spec 2's on there. What mm spacer would i need to push the rear wheels flush with the fenders? the front is perfect i would just like to sit a little more flush in the rear. Im sitting on h&r race with billy sports.

I want to run sum Schmidt Space line wheels.. I was thinking of getting 17x7.5 et 35 up front and 17x8.5 et 25 in the rear. Well this fit without issues or do I need a spacer up front. My fenders are rolled slightly. I was thinking 215/40 up front and 235/40 on the rear..

I currently have 10mm spacers up front and 15mm spacers in the rear with my current set-up 17x7.5 all round with 215/40 schmidt CC line revolutions..

thanx!

Looking at a set of old school rims as follows on my E30:

15x7 ET 27

Would those fit without any modifications?

[Knoepfler]

Should I get 215/45/16 or 215/40/16 with:

16x8's et 20 with 10 or 20mm spacers (I'm going for as best fitment as possible)

KW 60/60 cup kit (in sig)

I have some 16x7 et25 XXR 522's waiting to be put on my car.

What would be the best tire size? 205/45/16? I know it says don't ask for specific brands or types of tires, but I'm no good with differentiating tires so it would be nice if someone could recommend some good tires

I got some rota grid v 15x8 et0 with 195/45/15. Soon on gc kit. Fender rolling needed? Oh and the centerbore is 67.1 I think, but does hubcentric rings work?

5mm should be okay without a fender roll. 10mm would look better but will definitely require rolling.

Put the 15mm spacers up front with the space lines. Everything else is spot on.

Yup, with 205/55 215/50 or 225/50 tires. No fender rolling.

Best fitment suggestion:

205/45 tires
No spacers up front, 10mm rear
Rolled rear fenders

For no rolling:
205/45 tires
No spacers up front, 5mm rear

Not a fan of 215/40 tires as they are very undersized. They exaggerate fender gap not only at the top, but increase the space fore/aft of the tire.
