Model Y efficiency and performance impact with tall and narrow tires

See my previous videos. 10% energy savings were measured in June tests. It's true that 10% lrr tires don't give that 10% more range. In next consumption tests savings should be around 12% for best setup. But those will come next year after the winter. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Iv_Jk086V6w.htmlsi=BtTAZX2B4PVAL8eT

I also cannot wait for the next tests. Currently there is over 10 cm of snow, but lets see if I get the airfield cleared from snow to make the tests happen next weekend.

At the moment there is only a winter tire in the market in that 205/60r18 size. 18x8et30 sits 4mm more in to fender 205/60r18 tire outer edge is 15mm inwards 225/60r18 sits same place as oem sr model y tire outer edge. Check my other videos for more test details, more is coming also in the next days.

Not yet. But that 195/60r18 e primacy is quite optimal for model 3

Picture from 50 seconds in this video has the data. 24kg weight saving from wheels and tires means only 0.3% difference in energy consumption at 100 km/h steady speed. So not important at all for cunsumption wise.

@@TunekoLtdso wheel diameter is more important than weight for savings? It’s interesting to see the weight decrease still helps highway efficiency. So many people keep stating “ heavier wheel keep inertia up and makes it easier to maintain higher speeds “

For Zoe I would try 175/65R15 ecocontact 6. In general the ecocontact 6 should be better in real life consumption. The ePrimacys just have better rolling resistance in the rolls. Main reason why I use them in the tests is that you can buy them used really cheap as people buy winter tires in Germany. For some reason there is not so many sets available in ecocontact 6 series and they are much more expensive. however I will try to grap one 195/60R18 set for next summers tests if I find a bargain. If you go to car dealers and look tires they are not designed to same specs on some model Michelin are narrower and if you look other model goodyear is narrower vs e primacy. That is within same tire size. Citroen shops particularly they have same car offered with two manufacturers tires.

Those braid fit only Model 3

All tires are A rolling resistance exept the 215/55R18 ecocontact 5 is a B rated for rolling. I will gather that data on results.

@@TunekoLtd ok! While we are really going into depth, you might also look on the tiresidewall info for threadwear, traction and temperature. Also interesting when comparing i think.

@@Aarthodo That is interesting information which is almost never mentioned in tire tests. I will also release those numbers

It won't make the ride much softer if that is your goal? I am preparing a video on the ride hardness impact. You should have 225 wide or narrower to be able to notice different in ride softness. Impact to consumption is minimal by going just one sidewall higher. Rideheigth gain will hurt, but bigger tires you put, fill your wheel wells and arches closer and it will help. Also taller tire diameter helps. So roughly +-0 impact to consumption.

For Model y sr 17 in steel wheel and correct offset.
