which rim size b3

hi people, in the early years there are a few new complete summer showers for my b3, bj 88, 2,0E. I just recently bought the car. find it great! winter tires are great, only you rims of the summer tires are dead! now I thought, there have to be some new ones on it. now my question: I find it very horny, if the bike closes with the wheel box quite exactly, so already wider than 165 g! lol may the rims be a little bigger! what do you recommend to me and what do I have to spend?! my pain limit so lies at 1000 euronen…… may be less! would also take well-preserved used many thanks
