Wow, that's unfortunate... it's often a case of weaving all over the place with low profile tyres... my current 19" rims are a nightmare. Thankfully I've only curbed the front left once (and that was on one of those stupid bumpy stone curbs).
Do you not have any alloy protection as part of your purchase? I took out their platinum protection plan because it covered alloys, chips, small dents etc and GAP insurance.
