E12 rims replacement - help!

[817oakley]

Hi all,
i have an e12 520 euro model. They have the TRX 14 inch original rims. Rather than having to buy classic Michelin’s from Coker tire at 350 bucks a pop and hoping never to get a flat and not having to wonder if Michelin will ever stop custom producing them for Coker tire for us vintage car owners I would like to swap with a compatible rim from bmw or any other after market such that tires are not impossible to find. Every search of rim shops online comes up with bubkiss- nada or a 16 inch rim I am not sure will fit. Don’t wanna put a wheel adapter on it either. I know the bolt pattern 5x120 and offset is M according to specs. I am not sure of the center bore. I have read that it can go up to a 16 inch rim but would love to keep it 14 inch or 15 at the highest. Any suggestions of what other bmw rims would work would be helpful. Thanks.

I will move this from 5 series general to the E28 forum (we do not have an E12 forum), maybe someone there can help
