Yep, maybe. Wide tyres on these cars are mainly for looks unless the car has been pretty modified and therefore needs the extra grip.245`s all round would be better but then the grip is too high on a std car(IMO), plus putting 245`s on the front might rub.

A great thing about the M3 is that the grip\handling balance is great. TOo much rubber = too much grip. For 280+bhp, 245` all round would be the best way to go though I`m sure.

I am currently on the lookout for a narrower set of wheels for the back of mine because 225`s on the 9 inch wheels will look a bit weird 8-). Bit difficult finding just two 8 inch wide RS`s though in a good condition.

I'm running 225/45/17 (0n 7.5) and 245/40/17 (on 8.5) Michelin Pilot SX. As i'm new to the car I wanted to see what I had to do to get the car to over steer. I had to 'nail' it in 2nd from 4000 rpm round a damp bend to get the back to step out! Easy to correct. I almost wonder whether I'm 'over-tyred'? I mean if you have to go that hard to get the adrenalin going that's getting a bit OTT on a public road? I can get my M535i to step out at the slightest provocation...at least at speeds where I'm unlikely to do myself a really serious injury.

I've almost started to question whether the M3 is almost too good to be safe....if you can follow my warped logic?

Just my rambling thoughts.....

Hi there!
Wheels are 8inch fronts and 9 inch rears. Tyres are 225*45 front and 245*45 rear.

When you`re already accelerating around a roundabout its a bit hard to jump further on the accelerator :). I can induce oversteer but I usually do that by fast entry on to a roundabout with quick sharp steering (not smoothly steering around it) and then some good throttle.

PS I dont do this all the time, but I have some wide safe roundabouts near me and been experiementing when its a bit wet 8-).

Hi Darren,
I am running same sizes. What exactly do you have, rims and tires? 225/45 front and 245/??? rear?

Are u not concerned about understeer? I have 225 up front and 245 on the rear on 16`s. On damp or wet roads I can feel the front end atart to understeer when cornering quickly.

Try to put wider rubber on the front if u can


I finally got my M Contours down to the wheel shop to be refinished and wanted to make sure I bought the correct spacers and tires. The wheels are 17x7.5 up front and 17x8.5 in the rear. The tires I want to go with are Yokohama AVS Sport 215/45/17 up front and 245/40/17 in the rear. I know a couple other folks are running M Contours as well. I'd appreciate some advice on what size spacers I should use for this setup.

Thanks and take care.
