E31 factory tire sizes
Original-equipment sizes by trim and wheel package, from the fitment listings linked in each row. Front and rear differ on staggered setups. Rows marked verified appear in both tiresize.com's and Michelin's fitment lists for that model. Pressures and run-flat are shown only where a BMW owner's manual table covers that trim and year; star marking isn't confirmed yet. Your door-jamb placard has the pressures for your car. Pick your year and trim.
