No, not a whole lot. I'm currently running about the same pressure as I ran in the Contis... about 34lbs up front, and about 36lbs in back. Any suggestions?

38-40 up front would make a huge difference.

I don't have experience with the PS2 but the same pressure might not be ideal for 2 different tires. So just because that worked with the Conti's doesn't necessarily mean it will for the Michelins.

If it were me, I would swap those pressures....36 up front and 34 in the rear, or play with going up and down a couple pounds to see what happens.

And before you say it...yes I know BMW says to put more air up front but they are also the same people who put that tiny 225 front tire on there to begin with.

I bought both sets (15mm front, 12 mm rear) at TurnerMotorsport: http://www.turnermotorsport.com/html...6&subcat_id=93

... one caution, though: there is a possibility of rubbing the rear fenders when used with a brand of tire other than the Potenzas RE750 that I have. The same wheels/springs/spacers and tire sizes where used in a M3Forum member ride and he told me that in his car it rubs the rear fenders. I have no rubbing at all in my setup; I cannot remember what brand of tire he was using, but that was the only clearly evident difference between my car set up and his.

Thanks for the info Technic. Not going to do anything to the suspension right away, just the tire set up. I will keep it in mind for future referance.

nope, they are the RG4's from RAC monolites.
lighter and stronger than the ZCP or CSL wheels, with a more agressive offset, and they are a bit wider... 10/19r 9/19f.

thanks though, I like them.

Anyone care to post their own specific experiences in going from the stock 225/40R19 front, 255/35R19 rear to the wider 245/35R19 front and 275/30R19 rear? Did you find that the wider tires were mostly a cosmetic issue, did the tires tramline more, etc?

Thanks in advance for any feedback

Don't know if you are still following this thread, but I have Dinan's 19" wheels (9.5F and 10R) with 275/30F and 285/30R S03's. No interference issues at all. Turn in was improved enormously. After nearly 20K miles (no track) the tires have become noisier and tramline more. I'm going to put PS2's on next week. (Nothing against the Bridgestones, but I'm looking for a softer ride with the Michelins.) BTW I also have Dinan's complete suspension set up including the camber plates. The air pressure discussion raised on this thread will have me experimenting with more air in the front.

On a properly built set of custom wheels, like CCW's that are machined specifically for the E46, you can fit a 275/30 on the front with a 19x10 rim like I have right now, no fender rolling needed if you run some negative camber. You could also go to a 295 tire on a 19x11 on rear, but you'll need to roll fenders

For the track a 275/285 hoosier combo workes nicely on my CCW race classics 18x9,5 and 18sx10.5. A better set up would be to get 4 - 18x9.5 or 10 inch wide rims and with 275 tires the whole way around so you can rotate them. WIth the right back spacing you should be albe to pull this off with no spacer or a very small 5-10mm.

Hey Technik, I have the same dillema as TD330ci. I currently have stock 225/40/19 and 255/35/19 on my m3, but would like to switch to 245s and 275s. What I am concerned about is that if i go with 275/30 the overall diameter of the wheel will come down to 25.5" as compared to 26" stock. If I go for 275/35 it will be bumped to 26.5" and am told that I will most likely need to roll the fenders. Do you know if reducing the OD to 25.5" can be a
problem, especially since my fronts will stay at 26" (ABS, DSC ???). I assume the odometer will be slightly off but I am not concerned with this at all. Thanks in advance.

Hella nice black M you got there!

I dont think its blingy. Anyways, when the customer first wanted 20s in the rear, I was also thinking why, but when everything was all done and lowered, it looks pretty awesome in person

why?
to increace underateer, which the car has too much of already?

I am running 265f/275r and the steeering is so neutral that it is almost perfect.

I would want to decrease understeer- rather than increase it!

That's why serious track and autocross people are running same size tires front and rear.

20" are pure bling, overall the combos are heavier and the lack of sidewall height reduces the ability to get the tread flat on the ground. Look at F1 cars, or pretty much any other race car, there needs to be some sidewall height to make the tire work best.

And there is a dearth of GOOD tires for thoses sizes.

If you are doing it for looks, fine. But for performance, you are doing the wrong thing.
