Tyre Size Question

OK this has probably been thrashed to death but I'll ask anyway:

I have 195/45/16R 84V tyres on my car currently, If I was to swap them to 195/50/16R 84V would that create a significant difference in the speedometer measurement?

    Think it drops it out of the legal limit, so you'd end up needing a recalibration.

    It's a difference of 3.5% (the max recommended is 2.5%) and when your speedo says 60 you'll actually be doing 62.

    you can buy my 15" multispoke zetec alloys if you want :P ? They run a 50/55 i believe. Still plenty of tread on them too so no need to buy new tyres lol.

    As Nath says you will need to re-calibrate. This site helps you find tyres that would fit within the 2.5% change

    Your only real option would be 205/45/16, provided they'll fit on the rims.

    They should fit fine, but no larger than that really.
