The method to adjust the speed calibration through the nav system is in the thread titled "Speedometer Reads 6% High". I believe the steps to bring up the service screen were - Turn the audio power off, then press Map, Map, Map, Audio Power, Audio Power, Map. I have tried this on my 2018 SL with no luck.estomax wrote:for those with navigation you can adjust the speedo error slightly through the nav screen. there is a thread about that here somewhere. You can do a -2.5% offset and get your 205/55r16 to read dead on. Otherwise the 17" wheel Leafs are a bit bigger OD than the 16" (215/50r17), so going with taller profile could correct speedo error. My SL (with the aforementioned tires) has less than half mph speedo error compared to GPS at 65mph.
I will be buying a set of Ecopia 422 plus tires before the end of the month. The OEM Ecopias on the 2011 worked well under wet conditions if inflated to 44 psi. The Michelin MXM4 replacements worked well and had a little better dry traction. The OEM Michelin Energy Saver A/S tires on the 2015 were probably the worst radial tires I have ever owned--wet traction (on oil-soaked wet pavement typical here during storms after long dry spells) was non-existent regardless of inflation pressure. Both sets of Michelins had excessive weather cracking on the sidewalls in my climate. The Continental sport performance tires I put on the 2015 were great when new, but they dropped the range by at least 15% and their wet/dry grip has dropped as they have aged. The Ecopias offer the best range of any tires I have used on either LEAF and they have good wet traction so I am going back to them. My only decision is whether to stay with original size of 215/50R17 or go up to 215/55R17 to get slightly larger diameter.mwalsh wrote:I guess here is as good as anyplace...
I just went back to Bridgestone Ecopia tires on my 2011. Reasons:
The Ecopia 422 plus were $20 less per tire than the Michelins.
The most local tire place had 4 in stock and there wasn't another of their stores locally with more than 1 of the Michelins.
Got about the same number of miles from the Michelins as I did with my factory Ecopias (actually 40k vs. 35k, but I let them go more).
Michelins had great grip when new, but atrocious (dangerous even) grip towards EOL.
That's still my impression after a full day with the Ecopias - they are a little more squirrely than the Michelins, and I find myself somewhat missing the surefootedness I felt with (in my case) the MXV4s when new.GerryAZ wrote:The Michelin MXM4 replacements worked well and had a little better dry traction.
