Suspension design for comfort is way, way more complicated than tyre height and wheel travel.
I had a ride in a McLaren 720S over the summer. It rides better on 35 profile tyres than anything I can remember sitting in. People told me this before I got in but I still wasn’t ready for it. It’s properly luxury car smooth.
Teslas just aren’t engineered to ride well, you’re polishing a whoopsie trying to change that.
Honestly, it's going to give you a better ride but it won't feel luxurious. The XC60 is taller and I imagine has a bit more tyre to arch clearance so Volvo can build in more travel into the suspension to help cushion bumps.
If you take a pic of the tyre size from the tyre sidewall we can work out which tyres you currently have and how small a wheel/big a tyre you can possibly fit.
