New wheel and tire fitment

About to go with some new wheels and just want to get some input on this fitment - would be greatly appreciated.

19x8 et45 (with 15mm spacer)
19x9.5 et53* (w/wo 5mm spacer)

245/40 F. 275/35 R

Alternatively I could downsize tire width in both front and rear - but I like a bit of beef on my tires.

Those rims look similar to what you have now. Why bother changing it?

stock wheels are garbage. I have had 3 tires and 4 wheels replaced in 15k miles.

I am going for an OEM look on purpose without the run-flats and crappy soft wheels

Wheels look ok, spec is good. You might not even need spacers for the rear. Just make sure you get good quality balanced spacers up front. I have an idea on how you feel about tires... i think i've read some of your posts re bent rims. You're probably paranoid by now.
Tires, with what you've gone through i would personally go with f: 235/40 r: 265/35. With non-runflat tires keep the tire pressure between 38-40f, 36-38r.
Although I run on 20's, with lower sidewall heights. I found the best ride and traction combo for me is at f:38psi, r:36psi, and i've never bent any of my cheap taiwan made (haha) rims.
Btw, have your alignment done after. Choose a reputable tire and alignment place. Its ok, if you have to pay extra. For as long as they specialize in alignment.
good luck!

Yeah - after a bit more research, using the C63 as reference, I think et51 is going to sit great (I already have the 5mm so I have them on standby).

I went with a Hankook v12 evo2 as I do 15k+ a year and feel I will get a bit more bang for my buck than a PSS or PS4.

I have a few friends who ran them on their Audi's and were very pleased.

Such good advice - so hard to follow haha.

Definitely doing an alignment. Might line up with 20k prepaid service with the swap (assuming 20k service includes an alignment - or at least alignment check). I will, otherwise, get one performed.

Thanks for posting - such a good set-up. And definitely makes me feel better about my fitment.

What, are you off roading in the thing? My tires/wheels are in perfect condition @6k and I don't see it going any different in the future **Knocks on wood**

honestly, I think I have a bad batch of wheels. I do have the 19's as opposed to the 18's but still it's a bit ridiculous.

I am extremely careful and have never bent a wheel in my life before this car.
