LE / SE tire options (17" rim)

I ended up going with Contiental TrueContact Tour 54 in a 215/55R17. My speedo runs fast by about 2mph. GPS indicates 50 when the speedo says 52. The tires do not yet have 300 miles on them there a signs of only minimal impacts to range and mpg. My primary mode is EV use around town. My daily range remains so far between 58 and 59 miles. If you factor in a bit of inaccuracy because of the speedo (.96%) that means my true range has been reduced to between 56 and 57 miles - not earth shattering. They reportedly have much better wet handling than the Ecopia. I'll see in a year how they compare in terms of wear!

 

Just to be clear - the 4% fast on the speedometer is not due to the tyre change. That would have reduced speedometer and distance readings readings by about 0.4%. The new tyres have a slightly bigger circumference.

And an deliberately high reading on the speedometer (arising from legal rules about speedometers) doesn't mean all the other readouts are skewed by the same amount, so a 4% "true range" adjustment shouldn't apply.

 

Yeah by my calculation the 215/55R17 is a mere 1.8 mm taller (sidewall, the tire radius), compared to stock 17” 195/60R17:

(215*.55)-(195*.6)

And the 19” stock tire, 195/50R19 outside diameter is markedly more than either
