I have an '07 C70. It's the first volvo out of 5 that I would steer anyone away from. I suspect that potholes are much worse in Boston than here in Memphis. There were two options for wheel sizes, 17" and 18". Ours has the larger and in two years we bent or broke 4 wheels. The bent wheels ended up in flats as the bead seal was compromised.

Because of the brake rotor and caliper size the smallest you might be able to go is the 17", which may or may not help.

After bending and cracking a couple of wheels and having them repaired, I asked the wheel shop if running a higher pressure would help. Their opinion was that the car is too heavy for the wheel material and design. Short of finding steel wheels with the right backspace and offset, you're kind of stuck.

OEM wheels are very expensive, over $1,000, so after finding one in a salvage yard and having it bend I began using aftermarket OEM design at half the price which don't hold up any better.

This was my fifth Volvo and by far has been the worst for maintenance and repairs, which I do mostly myself. Radiator, multiple coolant hoses, suspension, brakes, timing belt, water pump, trunk leaks, falling headliner, and now the top failed.

I love volvo but for a convertible I had much less trouble with my '70 Fiat 850 Sport Spyder, which is saying a LOT.
