I have one more dumb tire question..
What does the 30 or 35 mean? Is it the sidewall?
I ask because I would think that both the front and rears should be the same but, in the previous posters tire set they are different.

When comparing the STOCK/OEM tire size there is a difference in wheel rotations front vs back.
is there a reason for this, Such as handling or performance?
would it be better ofr the vehicle performance/handling to have equal tire sizes/rotations front and back (i.e. Going to 255/35F & 295/30R)

As far as the rears being 295, the only issue I have is that the difference between the front and rears is "supposed" to be 20. So 265 up front and 285 rear would be an identical set up to stock.
By going to 295 (and knowing we can't get to 275 up front) you are changing the geometry/design of the vehicle. In addition, you are altering the MPH/KM on the speedometer by altering the geometry. So, your speedo will not reflect your actual speed.
If 265 is confirmed, then I have my answer (finally) 265 front and 285 rear.
Although I would love 295's in the rear, I just dont feel the added size is worth the potential downsides as mentioned above. But it sure looks bad ***..

most manufacturers would match the rotation perfectly. Dont think it alter too much of handling at all coz the difference arent big. Im sure it makes a huge difference for F1 cars since they are driving at 200kms plus, but for us, doing barely average of 65kmh or less, theres no difference at all (or we can tell).

My coupe came with 255s in the front and 285s in the rear.
They do not have to be going up in 20s by any means, I asked my dealer ship this when I changed my 285s to 295s.
But yes, you are correct it fractionally changes the speed. Instead of going 60kms I travel at 59.8kms - I can live with that.

The coupe and the sedan have different setups. Coupe is designed differently, wider flares, bigger tires, etc.
255/285 on coupe is correct and the difference is 30
245/265 on sedan is correct and the difference is 20
If you went to 295 then you should have gone up to 265 in front
If I go to 285 in rear I will also go to 265 in front but, I will keep mine in 20 differential
I cannot confirm or deny what the difference in speed will be on your speedo but, I can 100% confirm it will not be accurate if you change the geometry from 20 or in your case 30 from front to rear.

The table provided above gives the given tyre size and it's over all diameter.
The aim is to keep the over all diameter as close to the factory sized tyres so the speedo isn't thrown out to much.
By changing the factory 35 profile tyre to 30 on the 295 allows for a very close match to factory tyre specs in turn not greatly affecting the speedo ratio.

These cars are not 4wd/ quattro
so tyres only matter on the sane axis. Ie front back
if it was 4matic then rotational distance would be important but its not in this case.
Thats my 2p worth correct me if im wrong
i had a rs3 and fronts were bigger
my gtr rear are bigger but profile is the same
iv had other cars with different front back profiles from factory.
Car feels great, grip from rear is very good and turns into corners much better. Im very happy with the result.

check out that link above, it will help with visualizing the radius/width/travel/rotations.
it will also let you see how two different tries i.e. 255/35 and 295/30 are 'same-same but different'

and the largest on a 9 1/2 rim is 285 so if going (large) is your goal and you want to keep your stock rims on a sedan you would put 255/35/19 on the front and 285/35 19 on the rear and you get the added benefit of a slightly larger diameter to fill the wheel well if not lowering the car. 285/30/19 is OK but with a slightly smaller diameter.
The largest PREFERRED size on the 8 1/2 is 245 and largest on the 9 1/2 is a 275

Lowered - 295/30/19 Dunlop Max Sport
CT,
295/30/19's on the rear factory wheels with no lowering and no spacers and no scrubbing.
Obviously this size is larger than recommended but this is what I'm running and I'm happy with the setup.
My my car is now lowered, and still no issues.
Still waiting on a confirmed 265/35/19 front tyre size.
I might just do it and see how it goes.
Thank god i found this tread again!! Hey mate are you still running 255/35 19s and 295/30 19s ? still no rubbing issues on lowered or non lowered cars? even on comfort or sports mode? which lowering did you use and how many mm drop. your tires are michelin PSS too? am currently using 255/35 19s PSS. Am changing my rear tires i like to go with you rsame set up 295/30.. If i decided to go wider wheels like 10.5 295 shoouldnt be a problem right?

265/285 or 255/295, both will fit no prob. I have 295 on rears as per my post and they only rubbed so slightly initially on factory 19inch multispoke on full load going thru steep dips at over 100kmh, so virtually there was no rub at all. There has been no rubbing noticed going thru the same patch of the same road with the same load and speed since the tires hav been broken in ie after about 1000km. So i'd say 285 would have zero rubbing at all.
the 295 woild look a little bulged on the factory multispoke, it doesnt affect performance nor safety but protects the wheels from curb damage so im pretty happy with them.

Upgraded the front to 263/35/19 and rears are still 295/30/19.
Also changed out the factory Dunlops to the newly released Michelin Pilot Sport 4S's which I highly recomend.
I've also fitted the K-MAC front and rear camber kit to stop the premature wear my last two sets of tyres suffered from.
Interestingly, now that my tyres are standing straighter (1.5 degrees neg camber on the front and 1 degree rear, was 2.7 front and 3.1 rear) the tyres still do not scrub out.
My car is lowered 20mm all round on KW HAS.
Hope this helps in you setup.
