Anybody try 285/35/19's on the rear?

I'll piggy back on this thread for similar sort of inquiry.

Will 245/35/19 at the front and 275/30/19 at the rear cause any type of issue?

Wider tyres = taller side walls as the 35 & 30 represent percentage of the tyre width so 35% of 245 is more then 35% of 235. This will increase lateral movement/flex of the tyre side wall and therefore the whole chassis :banghead: Furthermore, your in car instrumentation, in particular the speedometer will give you false readings.
You're better off sticking to recommended OEM sizes and widen the track with good quality spacers :beer:

What good quality spacers do you recommend Matt?

What can I get away with on mine for the rear?

H&R 12 mm is what I used with that particular set of wheels mate and it's what I'd recommend for the rear only. Pic below to demonstrate.
This is where I got them from: http://www.motorsportworld.co.uk/fra...725&PID=613035 :thumbs:

I used to run 245 on the front and 255's on the rear - I like oversteer
245's gave better turn in and more grip up front.

250s all round for me, feels great.

they will give increased grip when accelerating and under braking tho matt, but like you say taller means more sidewall to flex- so steering would not be as precise, but then you'd get a better ride too - ask bealo about that:hahaha: 235/35's will snap out of grip quicker too I think [ the thinking bit is where this may all come undone]


Also depending on your ride height and camber set up you may experience rubbing....

I agree with that :thumbs: nothing else :hahaha:
On a more serious note, the M3 CSL has a great, forgiving chassis and is all about cornering ability, not the 0-60 nonsense, so I'll be sticking to the tyre sizes BMW recommend :blalalala:
