Looking for the best tire fitment for 16x9.5 et 30 front and rear.
15mm spacers would also be needed?

you would need 25mm spacers to clear front housings.

easy. Your final fitment will be 7.5j + 5mm. An equivalent would be 8J+11mm. You can run wider tires if you want.

Thinnest adapters I have seen are 18mm though

I have a machined 5 lug conversion, pushes front out 12mm each side. rear is e30 m3 5 lug width, same as stock. I have a set of style 42 17x8 et 20 all around, im thinking about strapping them with 225/45/17 or should I go 40 aspect ratio? Thanks in advance for the help!

P.S. currently on eibach springs and bilstein sports, soon to be on full ground control coil overs, I have no problem rolling fenders if need be, fronts are already rolled a bit from P.O.

You will be limited to 205/40 fronts. 215/40 rears fit with a flat roll and coilovers. Everything else is far too big.

I have a set of 16x7.5" rims with 225/45/16 RE55S tyres. The rims appear to be et37. What's the minimum spacer needed up front? They fit ok on the rear with out rubbing.

15mm

Background:
I'm currently running 16x8 et8 front/16x9 et15 rear with 225/45/16 Falken FK452's all around. I'm happy, but I wish I went 16x9 square.

Tires are almost shot, and the only thing I can find without shipping internationally are two Toyo Proxes T1R 225/45/16 (and they're on clearance for $75/pc). I can ship two 245/45/16 of these for another $400, and I feel it is worth it.

My questions:

1: With 16x9 et15, how hard is it going to be to fit 245/45 in the rear? It is already rolled and pulled somewhat, but it looks pretty close as is.

2: I plan to swap the fronts out for 16x9 et15 as well, which will push my wheel out 6mm more. I've test fitted my current rears to the front and with a 225 it looks like it will work, but would you call me crazy if I try to fit 245's up front after I run out of 225's?

Neither proposed idea will work.

Need a lot more info.

[Mystikal]

Will that rub even with a fender roll?

I'm struggling to find decent 17s new to run 17x8+20 front and 17x8+25 rear.

Thanks for your help.

Yes.

Late Model e30 with rolled fenders on ground control coils, lowered but not dumped.
- car is a turbo car (s52 turbo making 500+whp) so looking to fit largest rear tire I can on the apex acr8 17x8+25 wheels.

Can I fit a 245/40 out back on that wheel? or should I stick to a 235/40 square setup?
- street tires also no Hoosiers. Most likely NT01/Toyo R1R/R888

Thanks!

245/40 should work but you might need to raise it a bit.

[Mystikal]

looking for some guidance. Have original basket weaves on my e30 325is. I was looking at getting 205-60r14 Falkens but can't seem to find any. What are my options? No spacers or hub changes for me. Thanks

That works. Never seen adapters smaller than 18mm though.

From what Ive read this setup isnt a perfect fitment, but the price is great for a new wheel, and I like the look.

I am at stock ride now but may get lower by up to 2".

What are the recommended tires / spacers for this setup?

Forgot to mention This is for a '91 318is.
Thanks !

Anyone know what's the widest tire I could mount on a 17x7 wheel 40 offset I could run 20mm spacers

You will need 5mm front spacers. 205/50, 205/55, 225/45, and 225/50 all work.
