Yes. Get all the wheels cleaned of brake dust and checked. This is an issue people don't think about. Brake dust contains metallic particles and when they combine with winter road salt, water and alloy a corrosion battery is formed. So it's just as important to clean brake dust off the inner surfaces of alloy wheels as it is to clean it off the polished outer surfaces. Inner rims of alloy wheels are also damaged and cracked by straddling speed cushions. Never do this. Always drive one wheel over; one wheel on the flat. Wreck your springs rather than the rims or the tyres.
