Maintenance Schedule

[Jamas]

When is the first recommended maintenance visit for the Kona EV and what work is to be performed? I read somewhere that it is 6 months for a tire rotation. However, I just noticed that the dealer placed one of those reminder stickers on my car that says 3700 miles. Any thoughts?

Manual says 5000 miles for tire rotation..

The dealer told me 5000 miles for tire rotation.

 

[Jamas]

Thanks for confirming. 5000 miles it is

Since tires are not typically warrantied by car manufacturer's I personally would do whatever your specific tire manufacturer suggest. Its typically 6000-8000 mile rotations. That said doing what the manual suggests is a safe bet.

From the owner's manual:
"To equalize tread wear, HYUNDAI recommends that the tires be rotated every 10,000 km (6,000 miles) or sooner if irregular wear develops."

Yup, especially with 291 ft-lbs torque and regen, the front tires are going to wear quickly.

Any thoughts on front to back, or cross rotate? I also wonder if the TPMS sensors can be (or need to be) reprogrammed to give accurate locations.

My understanding is that TPMS communicates with a sensor at each wheel well area. So doesn't matter which tire/wheel you have there, it will report the correct one.

Thanks just saw this:

Hope it works. on the Leaf I had to do a "virtual" tire change using Leafspy.
I will check when the time comes and report back.

Just curious, how does regen factor into the wear of the front tires?

 

[KiwiME]

I can't see it being a significant factor and no worse than front-biased hydraulic brakes.
If you rotate the tires as recommended you're spreading the wear around anyway.

When you use your brakes, all four wheels are used to stop/slow down. But with regen, only the front ones, so they take all the wear of regen braking.

And of course with FWD vs AWD, all that drive wear is also in the front. I had to rotate my Prius tires more often for that same reason and the wear on the front tires was quite noticeable. Having said that 6000 miles or 10K kms should be good enough.

I'm still not clear on how regen (or even regular breaking for that matter) contribute to tire wear (unless you're skidding). Isn't tire wear simply a function of the tire making contact with the road?

Wear is caused by friction between your tires and the road. Regen, drive torque/force (as supplied by the engine), and braking all increase that friction. Of course, skidding or spinning dramatically increases the friction. The rear wheels don't have the driving or regen force, so they wear less quickly.

If you measure your tread depth with a caliper (I do that regularly) you will find that your rear tires always have less wear than the front ones, on a FWD vehicle. Some cars also have slightly more weight in the front (not the Kona EV, I think), and that also contributes to more wear. That also requires higher PSI in the front tires. And of course low tire PSI also greatly increases that friction (as you will notice with higher fuel or kWh consumption).

And as for tire friction, all cars have that. You would need steel tires on steel rails (like a train) to dramatically decrease that friction. If there was no friction, you could push you car forward (on a level plane) with just your small finger.

Hmmm. When brakes are applied, isn't it at the brake pads where the friction takes place (or resistance in the motor in the case of regen)? I understand there will always be rolling friction between the tires and the road, but isn't that unrelated to braking?

UPDATE: Okay, I think I found the answer. "As we apply the brakes, weight transfer occurs from rear to front , thus more forces are transferred to the front tires." This must have been covered in physics class the day I was out sick ;-)

Takes place at both the pads, and at the road, as the tires try to slow you down.
