M3 TYRE SIZES ???
Discussion
You can run 235/40 and 265/35 if you want a bit more sidewall, bit and comfort.
You can also run 245/35 and 275/30 if you want wider for a bit more grip, although it may tramline a little more and does drink more fuel.
You can also run 225 or 235/40 and 265/30, this gives a little more bite into corners up front and a slightly higher gear ratio on the rear with less bite at the back. This is what the CSL comes with as standard.

Interesting. I've always stayed with standard mind you, and when I say CSLs, I mean the CSL replicas that came as standard on my CS; not a wannabe CSL! Just got a whole new set today of the Conti SportContact M3s - a rather wallet-lightening experience... 235/35/19 on the front?? you mean 235/40/19'S???
235/35 is too low a profile.
I have just gone back to 235/45/18 and 265/40/18 and the difference between 225/40/19 and 255/35/19 is something else.
The car feels lighter, steering is more precise, it bites into corners again properly and it doesn't twitch about on our crappy UK roads which inspires confidence once more.
I prefer the look of the 19s, but the don't do the car any favours at all. That is why I like 245/40 and 265/35 when using 19s, it feels more like the car on 18s just not quite as light and nimble, however, it is my second care and I only use it when having fun o I have decided that handling is going to come before aesthetics from now on.
I had my 18s finished in anthracite to make them look a little different....

Its a pretty standard upsizing size to use as far as im aware (according to guys at Mtorque and M3cutters), when you put the 30's on the back, you need to go for the 35's on the front to keep the geometry correct. The 18's do give better handling than the 19's but i much prefer the way the 19's look. The ride seems good enough to me (but then i did come from a VX220, and getting dragged behind an M3 is comfatable in comparason)
It's downsizing really. It is reducing the diameter by around 3%.
Personally I would rather go 265/35 and 235/40, this is upsizing by 1%, bringing the speedo nearer to correct than the factory sizes and getting the car to handle just that little bit better.
I know alot of people go 275/30 cause they like the look of a really wide rear, and then you should use 245/35 to keep it similar.
The CSL 265/30 and 235/40 as a combo which works well, still keeps the bite going into the corners and reduces flex on the rear reducing overall understear a little.
Alot of the track set ups are 245/45/18 all round.
