Tire sizing

Stock tire size 195-65-R14

What would be better: 225-45-R16 or 205-50-R16 ? Why and how?

For a 16x7 wheel, tirerack recommend the latter but the speed error is lower with the first ...

go see at tirerack.com what they suggest.

with the 225-45-16 your spedo will be exact

with the 205-50-16 your spedo will be 0.4% too slow, so when your spedo reads 60mph (100km/h) you are really going 60.2mph

not a very big difference. what you wanna check, is how much distance you have between the tire and your strut, you dont want them to rub!
