I have an Impreza Sport with 16 inch wheels, my last tyres where 195 width and the fitter said these are the smallest he's ever fitted to an impreza. However they are the size I had when i bought the car.

What size is best ?

 

From memory, 205/50 16's should be on the 16's... so long as the rims are wide enough, should be if you've already got 195's...

 

I had to get spacers to make these tyres fit
