195/60/16 would be the correct size. So the speedometer is correct. The 'revolutions per mile' of a 195/60/16 is perfect as a replacement (so the speedometer is correct.
185/60/16 would also be decently close. Curious NO tire at all is for sale on Tire Rack at the 185/60/16 size.
Several 195/60/16 are available.
(I do not know the tire availability in Quebec)
The 195 would be a good compromise in tire size.. narrow and save gasoline. but not too narrow...
And 60 aspect ratio is fine. nearly all tires used to be 60 aspect. But now 50 is the standard
Thanks Elizabeth
There you go, Elizabeth looked up the actual size that would work.
Metric sizing makes MUCH more sense than the old American letter sizes (at least it means something in itself).
Still not the easiest to figure as sizes can vary a bit even when described with the same numbers.
Width is supposed to be "section width" across the sidewall of the tire, that varies with the rim width used though so it may be different on your car.
Tread width isn't measured at all, so that can vary a lot between different tires of the same size.
Then for height, it's measured by "aspect ratio" which is a percentage of height vs. width. (50 series is 50% as high as it's wide at the shoulder)
SO, any time you change the width number you have to change the height ratio JUST to maintain the exact same height of the tire in actual measurement.
It would be easy if size was measured by tread width & actual height from tread to bead edge, not NEARLY that simple.
Clear as Mud?
Tx for the translation offer BTW, high school french just won't do for actual use.
Hehe yeah i searched for the formula so i can learn how to calculate it next time. I have difficulties with mathematics its..pretty incredible and i sometimes wonder if its not discalculia..! Thanks once again tho the answers are perfect.
As for my offer i also meant helping out in case someone wants to know which websites are good for searching used cars etc. or a member of FF gets scammed and needs to investigate/search for co.'s/individuals.
As for high school french and actual use, i dont understand?
And here I thought everyone with a car had
www.rimsntires.com bookmarked in their browsers. Give it a try as playing with the sizes helps to visualize how things change and definitely helped me understand sizes better. They show the tire in a wheel too so you can get an idea of how much bulge or stretch you will get with each size tire.

Thanks i'll bookmark that for sure and give it a read
I will go with the 195/60R16 that's pretty much the same tire you have now, the speedometer measure should be the same (speed reader)
Sounds right and yes regarding the speedometer it sure is important, it absolutely needs to remain precise. I never really thought about those things you know? I used to swap tires on my downhill bike and simply go on. This is totally different..[wrenchin]
From a handling perspective, I think these cars are under-tired at 215. I'd worry about the loss of grip on a 195, from a "safety" perspective (no, I don't think you'll crash & burn, but that heavy nose on skinny tires might make it interesting).
Tell me about it, i felt a slight loss of traction on my front drivers side going on an off ramp at moderate/high speed last week at the middle of the apex. You've awaken my performance-conscious side lol.. I'll check the price difference just for fun and while i'm there, just for fun....i'll check the price difference for 215/225. I guess i'd have to downsize the aspect ratio for a wider tire...? It happened 2 times this summer and the [

]$%? barely squeal before giving out.
Stock tire size on a MK1 Focus is 195, are the MK3's that much heavier that they need the extra 20mm??
Maybe they wanted to get better performance rating i dont know. A softer compound could also do it while remaining more narrow but then a wider sportier-look might of been what they were after
