S60 2015 R-DESIGN owner

[nkclair]

Hi All, wonder if anyone can answer me a question, I've just brought myself another Volvo, S60 2015 R-desgin with 24500 miles, and part exchange my S80 2009 over the weekend from Volvo Selekt, its a nice car, i notice how going over even small potholes or speed humps at low speed, it's so not comfortable, it goes through the car, the S80 was much better. the standard tires are 235/40/R18, i know there low profile. I've never had a low profile tires so not sure if its normal, the 4 tires are new.
Wondering at some point i was thinking to change them to 235/50, see if it makes it better or help or would that be pointless.
I have 30 days to return the car.

Thank you.

To keep the same rolling radius they would have to be 225/50 and yes, 40 profile tyres will give a harsh ride.

Thank you, not used to it.

A few things here , The S80 has a longer body so the wheels are further apart ( wheelbase) this helps with a better ride , Also the S80 is a limousine made for an executive ride . The S60 is a sports salon and is set up for a harder ride and gives more dynamic driving . I don't think tyres or wheels will make any difference at all . You probably have the wrong car for your needs ...

The problem may be the R-design suspension which is 15 or 20% stiffer than other S60s.

Only option for you is to switch to 16" wheels and put some 215/60 tyres on it or, as it is a Selekt car, you have I think 14 days to swap it. See if the dealer has something other than an R-design car to test.

I find mine (with the same size tyres) is a harsh ride and can transmit a lot of road noise on certain surfaces. It's slightly better with the tyre pressures at 35psi.

Thanx all, just need to get used to it. Once again thanx for the response

I have a D3 with 235/40/18 and I must admit it's is really not the most comfortable ride in the city here in eastern Europe. But on the highway on the other hand this thing is just flying and rock solid on the road.

Today the winter tires got placed. 215/50/17 Continental TS850P. brand new ones and I have to say it really doesn't make any difference at all. And you have to know that as far as I know winter tyres are much softer. So go figure.
I think it's just the suspension and nothing you can really do about it.

on the motorway yesterday, had a warning low tire pressure. I went to check the tire pressure and the rear were set to 36psi and 33psi. The front were set to 48psi and 49psi. now i know why the car was bouncing like a pimps car. it drives much better then before. am shocked that Volvo selekt didn't check that, as part of there 100-point check, should be 101.
should there be 33 all around. i know the cars on the door says 33psi ?

Tyre pressures ARE part of the SELEKT check and you should have a ticked checklist in your paperwork to show this .

It is advisable to set tyre pressures to ECO which is good in all ways as long as you are happy with the ride . In any case do not let any pressures go below 35 psi otherwise the edges of the front tyres wear prematurely and fuel consumption will suffer .
