Suspension knock with winter wheels
Hello
Currently experiencing some noise in the front passenger strut Going over speedhumps and adding steering input (right, in the direction of travel) sometimes generates a "Ptwooooing" sound. Also experiencing some slight steering creak in low speeds. Anyone have any idea? Öhlins, New Top mounts (2021-06-01) and problem free before swapping to winter wheels. I have removed the wheels once -> cleaned hub and rim surface -> 140nm torque to lug nuts |

**** RESOLUTION******
So the problem occured with winter wheels being fitted The dimensions of the winter wheels (235/40r18+255/35r18) changed the rake of the car decreasing the tension on the front suspension allowing for movement. Now if this problem only arises with customs spring rates or no is a different question. Edit: I'll add that the front passenger needed a lil' extra preload to avoid spring movement. I also torqued down the locking ring afterwards Last edited by DonPedron; 01-08-2022 at 04:57 AM.. |

16mm and 42mm are a huge difference in diameter compared to the summer tires. Generally +/- 9mm is the acceptable maximum. Or are these studded?

Nokian Hakkapeliitta R3, hard core snow tire but not studded. As grippy as can be in snow and on ice.
I also have a set of wintercontact from Continental, just doesn't cut it for me. That second set is 235/35R19 square. Squiggly back end, terrible grip. Downright scary tires. |
