Hi

I recently purchased a 1987 740 wagon. It came with five spare tires (3 new, 2 part used) as it was running on winter tires (I am in Canada). I came to change these and realised that the all season spares are 195/70R14. The tires that are on are 185/70R14 as recommended in the owner's manual. Can I use the all season spares in spite of the size? Will it have any impact on the speed reading on the the dash?

Thanks for any clues.
