Is the climbing performance of MN168 “falsely labeled”?

Official propaganda VS actual test experience: “Officially said that it is easy to climb a 45-degree slope, but it slips at 30 degrees! Is it a technical problem or false propaganda?”

From a technical analysis: tire material (hard plastic vs. soft rubber) and differential design (open vs. locked) directly affect climbing ability.

Real feedback from users: Some car owners have significantly improved performance after upgrading OP tires + metal differential gears.

Official response: It is recommended to check whether the tires are worn, and provide a free differential lubrication tutorial (official website download).

And what everyone is arguing about: Should a “professional climbing version” accessory package be launched?
