The MR33 tire roller is used to prepare your racing tires.
As you probably know, many drivers "roll" the new tires with a little pressure over the setup board before using them for the first time.
This process serves to "break" the superglue in places where too much tire glue may have been used. this process is used to "break" the superglue in places where too much glue may have been used.
You can also press the tire insert a little flatter by rolling, which increases the air (the distance) between the insert and the tire rubber.
If you simply use an Allen key or another tool for rolling, you cannot apply even pressure.
Likewise, you then press exactly on the edge of the hole through which the wheel axle will later be inserted, and this can distort it - anything but perfect!

The 3D printed MR33 tire roller is the perfect solution.
It fits perfectly into the rim and provides even contact and pressure during rolling.
The hole in the rim is also not stressed and retains its original shape.
