bbs sr wheels

Hey folks, I have some almost brand new BBS SR wheel on 18x8 with 235/40 R18 95Y XL tyres and a rim rating of 795kg. Are these suitable for a a T32 SWB T6 if I get PCD adapters or am I better of selling them and buying van rated 5x120 rims? Is the rim rating the important bit or is it the tyre...
