I've had a contessa welded years ago when a tyre fitter gouged it with his remover and tore a 50 cent piece sized bit out of the lip , the fitter showed me the gouged wheel at first , then I picked it up that afternoon and could barely see it (wheels were fairly scuffed and the welded section was the best looking bit on it

) . Would I race on one that's had the center repaired ? no , would I drive on one ? only as a spare . I haven't seen them crack around the center but maybe I haven't seen enough of them that have had hard lives , if it's cracked there then what's the rest of the aluminium like fatigue-wise (but I'm ultra careful with pressures on wheels , I've had a wheel drop off in a 60 zone and that was enough of an eye opener , I'd hate to have one fail when pushing it hard ....)?
