i dun see any issues with replica rims, japan rims,german rims, taiwan rims, china rims, japan rims, thailand rims, indonesion rims, and sorts of rims...
if china cars of almost 200mil on the road with china made rims, is all going to be cracked ? So if our proton and perdua even the toyota rims which is made locally, going to crack like this ?
judging from the pictures, the rims must have broke on impact, knocked, hit hard on a kerb...
only thing that makes the rims get crack easily is lousy rubber and too thin.... think of 255/35/R19 tyres on 19" rims... it takes only one pothole to either crack your rims or dent it, or worse, like picture 1...
