greetings from another person still driving an s70.
I too am in search of tires.
My s70 is a base model and came with 15 inch wheels.
I have noticed that the selection of 15 in tires isn't what it was pre-covid. I also realize fewer cars use 15 inch wheels so there is less demand for them.
I had thought of picking up a set of 16 inch rims to increase my choice of tires but I concluded that the extra price of sourcing used rims wouldn't really benefit me as the choice of 15 in tires I have still contains tires I would be willing to put on the car.
I will look into whether the tires above still come in 195 60r15 .
195/60-15 still has plenty of options, as it was a common size, and of course, tires that small are very cheap too
