Thank you very much I appreciate it

someguy_99 · 11-12-2012, 12:55 PM

mmm

sakumaxp · 11-12-2012, 01:24 PM

maybe you have a sticky throttle?

Mircea's M3 · 11-12-2012, 07:38 PM

I know I find it so hard to believe that the different size wheels would do this but who knows

Dreamwerke · 11-12-2012, 07:49 PM

I guess we will find out as soon as my bud brings me his wheels..

someguy_99 · 11-17-2012, 10:21 PM

try getting it on video and posting it here so ppl can try to see what is actually happening

Mircea's M3 · 11-18-2012, 02:09 PM

So i figured out today if I take off the traction control it stops doing it. So like Dreamwerke said it has to do with the different size in wheels front to back. Traction control is trying to make up for the diference

Dreamwerke · 11-18-2012, 02:11 PM

That's good to know, because I still haven't gotten new tires or a full set of 1 size to keep on

All E46 M3s are drive-by-wire

What are the actual tire sizes?

Meh, all E46 ///M's have fly-by-wire throttle.

Mircea's M3 · 11-20-2012, 03:34 PM

Tires in the back are tall 255/40/19
Front is 225/45/17

And this issue doesn't happen once you turn the DSC off correct?

Absolutely 100% it's the mismatched wheel size(s). The car's stability control/traction control is confused by the difference in size from front to rear.

If I can ask, why are you running 17's in the front?

Mircea's M3 · 11-20-2012, 05:59 PM

That's correct
I got a flat on my 19 in the front, and I only had 2 winter tires on my winter wheels, so I put them on and I'm in process of getting two more winter tires for my other pair of 17s

So for now I have a ghetto setup lol

Copy that. Ya gotta do what ya gotta do ! Sucks about the flat, sounds like you just need to run her w/o DSC (carefully

) until you get the new replacement 19" tires. Use the force !

Mircea's M3 · 11-20-2012, 08:11 PM

we have no snow yet so I'm safe!

That'll do it.

Why are you running such tall tires on the 19s out of curiosity?

Because DRAG racecar bro.... LOL

Couldn't resist.

scca_ziptie · 11-21-2012, 11:04 AM

I ran 235/40/19 front and 265/35/19 rear and had no issues - the aspect ratio does seem to be a bit high on the rear tires (aside from the obvious 17" wheel issue up front).

Mircea's M3 · 11-21-2012, 07:27 PM

Can't wait to get them matched again
Looks like a drag car lol
