Like me with great restriction

The rims tree does what he should. It keeps the wheels - in my case 19 "265 (235 front / 265 rear).
However, I would not get the idea 4 wheels on this rim Tree store - 2 maximum are fine. 4 works in my opinion, only if you then tying the tree somewhere. This is already at the construction of the tree. On the conditions the wheels can very easily slip. That's enough to make you lose control around the tree. I've just now two rims trees bought and store only two wheels per tree. Thicknesses above, the thin bottom. It is safer than risking damage to the rims.
