Ok to cut a long story short, I did have a look thru the various wheel threads but they focused more on the wheel offset etc Vs actual tyre fitment.

the 215 50 17 size that the Stagea has now is limiting our choice of replacement tyre.

Has anyone actually FIT a 225 45 17 to their C34 S2 , ours has the "autech" rims not sure if they are any different than others.

I just dont want to order the tyres then get em here and they dont fit.

Anyone shed any light on this?

Stock Autech Rims are 17x7 + 30 front 17x7 + 20 rear. I run 17 x 9 +20 Wedsports SA90s with 235 45 17 with RE001s. Had floating spaces but f**ked them off. Needed nismo long bolts because of not much thread. Basically R33 GTR offset. I will not go up to 18s for daily driving only for show. Duncan runs these exact rims with Feds as far as I know.

Fitting these will be close to perfect, just dont rotate front with back because they are offset specific. You dont want to strech your tyre either, so 225s are fine for 7s. If you are from WA give chuckie a pm regarding Hankooks. Ive heard Nittos are also good and much cheaper. Buy a good set of tyres. Mine cost more than my rims but it has payed off in the long run.

225/45 will fit, but you will pay more then for a 235/45 as its a very common size, i have 235's on my autech rims and they fit fine, bulge a tiny amount but you cannot feel it when driving hard ish.

Id go the 235, can get em from $100

So if your 235 fit the 225 should be fine yeah? I just don't wanna order tyres then get stuck when they don't fit

Unfortunately I was away with work and someone else took the car to the tyre shop for me. The tyre shop had ordered in some 235/45/R17s for me and then when they took the car in, they rang me and said that it was illegal to fit these tyres to a 7" rim. That's all I know...

I'm away again, so can't confirm the tyre size that's on there now. I've asked the misses to check for me. She'll get back to me soon. I'm pretty sure they are 225/45/R17s and they are the tyres the compliance centre put on for me.

225 will fit on a 7in rim. You can search online for fitment charts to confirm if you want.

235 will fit but are not recommended although i don't know about ïllegal" especially when I see some of the stupidly "stretched" tyres that some people have.

Yeah they will fit easily.

Ive never heard of them refusing to fit tyres before, a 265 sure but not a 235, the standard stagea size is a 225/50/17.

Just being pedantic.

I have stock Autech Rims (17x7) and the stock fitment as far as i know is actuallt 225/50/17 from factory, and is what I'm running.

I have a slightly separate question for those with a 260RS.... What size wheels can I fit??? I have the bilstein struts and have lowered them as far as I can.

It seems to me like 18x9 will not fit, so was thinking 18x8 +15 for the rear, and probably +25 for the front (matching up the stock offsets).

235/45/17 are illegal on a 7" rim, narrowest it can be legally fitted to is a 7.5" any good tyre shop should refuse to fit them to a 7 because they can get in shit if you get defected for it as they shouldnt have fitted it.

i have 225/45/17 on my rs4s rims, apart from f**king the speedo reading due to the smaller rolling height, they fit perfectly fine. my speedo just reads about 9km/h under what im actually doing

They will be near enough the same...a little bit smaller so your speedo will read a little higher.

      You’ll be very upset when you bust that too not to mention the gearing totally sucks. Don’t do it.

      Is the panel filter one that is oiled? Have you ever cleaned or touched the AFM?

      So.... the K&N air box thingo was too big, ended up gifting it to a mate, well, by gifting it he actually supplied food and beer at the pub,  which was nice, as it will not sit on a shelf in the garage for the next 10 years I did trim up some of the existing stuff to neaten it all up and gave it some wrinkle paint, unfortunately it currently has a used and abused mish mash of different types of hose clamps, 4 big fat T bolt type (shit), and a few normal clamps of vairing sizes and brands, but..... only until the 6 constant tension black worm clamps that I ordered from EFI solutions turn up next week Currently the current hose clamps are triggering me hard, LOL Is this the final version, probably not, I really want just 2 silicone pieces, a straight bit of silicone from the filter to the MAF is easy and will happen as soon as I head into Just Jap tomorrow, the problematic part is a 30° silicone bend from the MAF to the TB that I can connect the engine breather from the head, I found that there are bulk head fittings for boat bilge pumps that should work, but until I can get a 30° silicone bend the alloy pipe, and the 11ty thousand hose clamps, are there for the foreseeable future 4 hose clamps are golden, 6 are grudgingly acceptable, the 8 currently holding it all together is just taking the piss    I've also ordered 60 more retaining wall blocks for the front yard, I mis-gonculated the height that was required to get above the base of the Photinia's (red robin's) that are the hedge behind the front fence, currently it is 2 blocks high, and about 1/2 a block short, so going 3 blocks high will be above the base of the red robin's, and allow some room for mulch

      It is the stock air box with the panel filter. Everything else is stock except the exhaust at this point, as I also went back to the cleaned 270cc injectors. I will check the RPM when the IACV is unplugged and report back.

      As MBS suggested if this is happening when the engine is cold you're going to want to remove the intake air regulator and verify resistance + that the shutter is physically opening and closing. At -20C should be fully open, 20C half open, over 60C fully closed. At 20C should be 70-80 ohms. For AAC valve testing using a Consult cable see if you can raise and lower the idle by commanding more or less AAC duty cycle. Hopefully it's pretty linear as well, shouldn't be like 30% AAC valve is barely idling and 40% is 1500 rpm.
