If you are going with the 99-01 E38 740 Sport rims they will fit right up just like it does on the E38 but on the E32. They are 18-inch M Parallel Spoke wheels 18x8 235/50ZR-18 front, 18x9.5 255/45ZR-18 rear I think these would be a great choice. The stock 15-16 alloy wheels aren't worth spending the money for new tires. Time to upgrade to today’s standards and increase your bimmers handling and looks.
