1988 OEM wheels/tire sizes
 

Do 1988 Supra OEM wheels fit 205/45/16 tires

As far as I know all oem mk3 wheels are 16in, so any 16in tire will fit on a 16in rim. But the size you talk about will fit and totally clear because it is much smaller than the factory size of 225 50 16. That size will look very small and throw off your speedo by a good bit.
