The Nexen will actually loose traction down a steep hill if pulling the left paddle, which causes the car to activate full panic emergency breaking but only half a second after fully disengaging regen all together. Very scary the first time it happens.
Ok ... I was actually planning such a driving style as the windy road to Bridgetown usually requires down hill braking ... so good to know. I assume this doesn't happen if in cruise control mode?

Will enquire today about swapping out and changeover costs.
Cruise control uses regen to maintain the set speed downhill. I drive with level 3 regen all the time anyway. Regen is not just on/off; you modulate how much with your right foot. Going down a steep hill with regen level 3 is like being in a lower gear in a manual petrol car without the screaming high revs.

If using the break peddle to slow down hard, the car will use regen to the maximum possible before engaging the breaks.
The beauty of using the left paddle pulled continuously is that regardless of the speed or incline, the car will never engage the breaks until the car is stopped.
The down-side is of course that being a 2WD, the breaking force is only applied to 2 wheels. I would imagine that a rear wheel drive, better under acceleration, would actually be worse for hard regen on a wet downhill road.
Despite the limitations, I use the left paddle all the way to stop 98% of the time. More free energy and my brake pads should last the life of the car.
One other thing to keep in mind, and one more reason not to charge to 100% all the time, is that the maximum regen is not a fixed value. If the car is fully charge, regen 3 or holding the left paddle will decelerate slower than with a battery at 60%.
The regen paddles as implemented by Hyundai are the best inventions since gravity.

I run Xice in the winter and noticed very little difference when I swapped for the OEM Nexens. Of course, that's a winter tire compared to a summer one. But don't forget that the Nexens are EV tires, designed to be hard and efficient. You won't find many EV choices designed with noise or comfort in mind. Not yet anyway.

A bit of a long shot - does anyone in Perth have a spare Nexen tyre as a result of swapping to the Michelins?

Just got a serious puncture in one tyre that might not be repairable. There is no stock of Michelins in Australia, and even getting a Nexen into WA will take a couple of weeks.

Hi.

Sorry, I didn't get to change mine over pre delivery, so don't have a spare Nexen. I always used TyrePower in Willetton here in Perth. The manager there is fantastic and might be able to provide you some guidance. Certainly my last conversation with him was that there were a few enviro options available for the Kona when I was ready.

Good luck.

Finally got to do a road trip with the primacy tires and am very happy with them. Got efficiencies I havent seen with the nexens with one run from Ballarat to Doncaster 130km and got 12kwh and never seen anything like that before. Apart from that the ride, comfort and grip are way up and tire noise is way down. Winner winner

Sounds like I'd better work harder on wearing out the Nexens then ... will try to reduce the 'eco' driving points and up the 'aggressive' ones. :twisted:

Someone had already put some really sticky sports tyres on my Kona before I got it. They really screw up the efficiency but the good news is they will probably wear out fairly quickly.

Hopefully though the local speedway will reopen first, it has a drag strip that is only 1/8 of a mile long. I have my old farmers hat ready and we will see who this nutter might upset first.
One of the good things about electric cars is that I already know what my times will be ( but I won't be telling) and can find out who I will beat.

Well Yes sort of,still waiting for our new Kona electric,our other Kona a Iron Man version wore out the Nexions in 20,000 Km, looked around for something with more grip in the wet and lower rolling restance,the best i could find was from Kumho Ecsta PA51, so new not yet in the tyre caterlog.they also have 8.3 mm of tread, after 2,000 km i think thay are a lot quieter, roll under no power better and have a lot more grip in the wet, all thought i found then noisey for the drive home,then found the tyre shop had left the stickey labels on them, 50kms later the sound of a lot quiter tyres, shame about the wind noise thought. :D :D

I don’t get it? My front tyres are just shy of 50’000km and probably still have 5’000km in them, and the rear ones (never rotated my tyres) are close to new. I know I drive gently, but not that gently.
Is it the smoothness of the electric drive?
I also inflate them to 42psi. Is that a factor?

I am at 23,000km and still have lots of tread on my Nexans. I expect I will also get to at least 50,000km before I can justify replacing them.

What happened was this: picked up the car from the dealer with just 4 km on the clock,after about 6,000 km later parked one day with the front wheels an angle and noticed the front tyres looked allmost worn out, not far off the wear band ribs,swapped the tyres front to rear and took the car to a 4wd alignment specialist , result both front and rear track were out by lots,paid $118 for the alignment,cheaper than tyres,car drove a lot better after wards as well. wore the fronts down from 50% worn to change them in 14,000 km.tyres on the iron man its AWD as well are 18 inch rims and 235/45/ 18 so not much of a sidewall at all,but max cornering grip on the road, :( :(
