Conducting field tests and kind of comparison of TRX4M and CR18P Evo Rock Van rigs with Injora heavy brass rings installed on front axle at the same stony track.
These heavy brass rings are specifically designed to fit the stock tyres of TRX4M. But I experimented how they will work with Injora tyres
As a result found that they can work well with some Injora wheels and tyres and with some not. An example shown on the video shows that the front wheels spin in the front tyre of the TRX4M as the wheel disc can no longer be tightened.
At the same time, in the Rock Van, the tyres are sitting quite firmly on the wheel with heavy brass insert.
In any case, it looks like the combination of the heavy brass ring with the brass wheel is too heavy for both car models as the front axle tends to slide sideways on the slopes due to the heavy weight.
I will probably go back to the normal brass rings which weigh about 12gr each instead of 34gr.
Despite small 55mm tires, Rock Van perform really nice
