33 Lego Wheels/Tracks on Wood (worst to best)

33 Lego wheels, tires or tracks tested on a wooded board to find the best traction. Presented in order from worst to best. Enjoy! Test method: adjust the slope angle until the driving car doesn't slide down or climb up but stays in place measure the angle of inclination calculate the coefficient of friction = tan(angle) Potential sources of error: traction varies along the wooden board (maybe +/- 1 degree of error in spots) wheel rotation speed varies (faster rotation adds maybe even 2 degrees to the result with some tires, tried to minimize it by using L-motor with large tires) vibration (happened noticeable only with 15038c03, those errors were omitted) weight varies (shouldn't matter in theory) uneven weight distribution on the 4 wheels angle measurement inaccuracies == the results are not very accurate, but I'm confident they are roughly correct All wheels were wiped clean before testing. The material of the wood board is pine, untreated https://www.biltema.fi/rakentaminen/s...
