Hi,

First of all: excuse for my bad English: I'm not native
I have been reading for some time here, and done some ecomodding

- Light weight lifepo4 battery (hi-genius from Taiwan)
- removed folded down bay in the trunk

- Adopted mild hypermiling techniques: coasting in neutral and DFCO
when needing to slow down faster.

I now have 4,8L to 4,9L/100km

Before all this, I would get around 5,9L to 6 L /100km

Now, my question:
Are there light weight donuts that would fit my car?
My wheels are 15"

I measured my donut: it is 15" x 4 ET39 bolt pattern 4 x 100
Tire on it: T125/70D15
Weight: 8kg

Would the Honda Insight donut work?
It is however 14"...
Do all yaris come with a 15"donut? or did you get at 14" donut if your car
came with 14" stock wheels?
What other lightweight donut would fit?

I do like the security of having something. (instead of removing it
completly)

Greetings and thanks for reading!
