Testing 6 LEGO Technic tires on different surfaces, such as sand, glass, grass, etc.
The main goal is to find out which tires are most suitable for a particular surface. For the test I use AWD car with 4 speed gearbox and central diff blocking mechanism, which I will also build in this video.
I use a PS4 gamepad to control the car and use a digital scale as a measuring device.

The final results are quite interesting, I think.
When I had the idea to test LEGO tires, I thought there was nothing special here. Larger tire, larger contact patch, better results. But, I forgot about the weight of the tires...

Surfaces:
1. Wood. Untreated 6layer plywood.
2. Glass.
3. Grass. Artificial lawn, imitation of real grass.
4. Stones. River pebbles, 510 mm.
5. Sand. River white quartz sand, 0.81.2 mm.
