I am used to drive cars with good balanced wheels. On the highway I am used to have a steady feeling in the car/steering wheel.
I am now driving the XC60 with 255/45 R20 Tyres.
So a relatively flat tyre. Is it normal that such tyres/wheels give a more bumpy feeling less comfort?
It drives still good and I feel no unbalance, but the car is just not steady on the highway. A light bumpy feeling in the car on certain roads.

Does anyone recognize this?

 

Yes ,big tires , less comfort , but it looks nicer😀

 

By less comfort you mean the light bumpy behavior on the highway and also feeling slight resonance (especially on rough roads) in the steering wheel (also at low speeds)?

 

I dont feel any bumpy behavior but In Nyc road are in very bad condition maybe that's why lol. but I got another problem looks like my car steering more to the left when I don't hold wheel I check the tire pressure but everything is fine there.

 

wider tires combined with poor alignment can lead to "nibbling" - where the tires tend to follow cracks or ridges in the road surface. When was the last time you had the car in for a 4 point alignment? When you take the car in, make sure you ask for the results print out as well that shows all the suspension measurements. It is also possible you have something worn or bent in the suspension - a proper alignment shop should inspect when they put the car on the rack.
