you think it has something to do with it?
Turn MDM mode on, it's a completely different animal.

One should avoid using it in rain or on slick surfaces, as it does allow one to get into trouble.

i just recently bought the car and the tires it came with are some cheap crap Chinese with 0 traction [literately].

When i accelerate hard [no matter from what speed] you get this uneven and not smooth power delivery its like the engine is tuning itself down on purpose [ and no its not traction control ]
i did coils \ plugs last week issue still there.
some guy in the m5 forum said it could be maf\o2 sensor i will try that out but i was wondering if the tires could have anything to do with it?
Excellent. Please take before/ after pictures especially showing side and rear quarter profiles of the wheels as I am interested in going your route too.

Appreciate it and hope it all works out well for you! Cheers!

Exactly. With all of the driver aids turned on it's just about impossible to lose traction, that is absolutely what you are experiencing. The car is pulling back everything to keep the motor from making power because brake pulses aren't going to keep those tires on the ground by themselves in these cars.

MDM is going to let you have some spin, but my guess is if your tires are really that bad you are going to still run into some limiting. Keep it on a straight road and you should be fine. It is amazing how controllable the cars stay in MDM.

your back brakes will be gone every 15k miles due to traction control. Also, I'd be very wary of turning TC all the way off. These cars can spin very quickly if you're not used to it

Bought the car with 255/30/21 in 295/30/21 in the rear. Gives it a stretched look, will raise the car and switch to 315 or 305 as soon as I can.

Sorry to thread jack,
I'm a long time lurker first time poster, and forgot my other accounts email password so made new account.
I have a 14 M6 GC CP with CCB's & 343M wheels. I'm looking to replace the tires and couldn't find the tire combo/size using the search bar.

Will this setup work on the wheels i have? Vehicle has no mods and is not lowered.

295/35/20 - Front
305/35/20 - Rear

35 in the rear is tall but will it work? also the front being 295 on the stock wheels, will that work? Thank you in advance for all the help.

front rims are too narrow for 295/35/20. You might also have trouble with the stability control. The standard ration front over back rollings ratio is 0..988 whereas what you you are looking at is 1.01 that is very close to the 2% limit.

Thank you for your input and information, i appreciate that. I thought so about the front wheel being too narrow. My next option tire size is as follows:

275/35/20 - Front
315/30/20 - Rear

Now, would 315 be ok for the rear? Im not looking for tire blow outs.
According to the tire manufacture, the tire requires a wheel width between 10.5" - 12". I know these wheels are 10.5" wide but i would like some input regarding this please

thank you

The 305 /30 fit. Have not tried 315 but someone else might be able to chime in. There are several discussions on tire sizes on the forum. Did you have a look to see?

I Did see only 2 people mention then fit, so not enough evidence in my opinion.
Also the ratio with the front tires i suggested, are those ok? for that 0.988 you were talking about? thats my main concern. that 1/1 ratio tolerance... I'd prefer not having any malfunction messages lol

Why don't you just find the "normal" size tyres 265/35x20 front and 295/30x20 rear (or 305/30x20 - that's what I'm running)? It's not as if you can't buy MPS4S in this size...
