..?Steering pull, normal?..

[rlubocki]

... I noticed that when riding on uneven pavement, the steering gets affected and pulls into the grooves of the road.
Is this normal on a Z4? I have stock run-flat tires, maybe thats the cause? I feel I have less control when the steering falls wherever there
are dips on the road.

Happy Holidays!

Welcome to the forum

Sounds like tramlining and yes pretty common with the stock run flats...

Do a search for "tramline" or RFTs. It's well documented. The run-flats are very stiff in the sidewall and tend to follow any irregularity in the road. Couple this with the very responsive steering and you get that "pull". Non run-flats help a bit, but to be honest, it won't cure it. I had a 325Ci that would tramline and it had "standard" high-performance tires on it.

Drive the car a bit and you'll get used to it and more confident in the handling.

Now, before the others chime in, :worthless: :lol:

I have been drining my mums fiesta over the hols and have been surprised how little feedback I find now Im used to the z handling- A first the z seems very unsure and tramlining but you will get used to it then u will love it!

my zed must be an anomaly then, cos it doesn't tramline at all on the Michelin run flats :?

Thank you for great advice, I thought this was abnormal. The steering is very responsive, and I am getting used to it… Enjoy, it’s an awesome car!!

Your roads must be better than mine!

Actually, it only tramlined on the most rutted road, but it would definitely keep you on your toes-this was with sport package and 17" wheels.
