definitive tire, wheel, and offset thread

[twinsteve]

I am seriously looking at getting custom made forged one-piece wheels from CCW....about $750 each including custom finish....if I stick to 18" (which I probably will for several reasons, namely the style I want they only make in 18 unless I want 19x10 which I don't), them width/offset is easy

If I wanted to do 18 but go a little wider than stock (say 18x9), then I would assume tire size 265/40/18 would fit just fine...would stock offset 30 still hold true or do I need different offset? Since they are custom made, I can get anything.....no immediate plans to lower, but that will change if/when DRC craps out

Thx!

yep, thx.....my concern is really around offset....does offset need to change from stock 30et if I go up to 265 tire width on 18x9?

Well, logic says you may want to go to an offset of 25 due to the increased width of your rim. By keeping the offset the same and widening your rim you'd be basically pushing the rim inwards. I'm not sure how much clearance the factory settings allow for on the inside. That being said, my 19*10's are using an offset of 25 with no rubbing so that implies a 9" rim would be fine without changing the offset.

I just got new (used) sneakers too...

Volk VR G2. 19x9.5 ET29 (on all 4 corners) (stock RS4 size)
Michelin Pilot Super sport 275-30-19

No spacers and no rubbing...fit perfect
and I just lost 10lbs of rotating weight per corner

18x10 ET 33. I'm guessing ill need 5mm spacers but what do you guys think? Will they fit?

not if you want a lowered ride height and like to push her in the bends and bumps

mine 19x9.5 et 30, 255/35/19...

will rub rears on extreme occasions (i mean very extreme) like air-bourne at 110 mph

Would these fit? Says for audi RS6 but then disclosures in red say not for 4.2 V8...wtf

Hey mate, I'm running stock B7 RS4 wheels with 255/35/19 tyres, the rims are actually 19*9 with a 29 offset not 9.5. Just to keep the numbers correct.
