Snow chains Deluxe - very easy installation

After my new vehicle had a different size to winter wheels than its predecessor, new tires were needed.
The current complete wheel star spoke 397 (all around 225 / 45-18) of BMW should support mounting snow chains according to the manufacturer.

But as I at the previous vehicle the Centrax could not use, although the tire / wheel size combination was supported by RUD, I was initially skeptical about whether the same problem would be - a bolt with mounting sleeve did not fit on the wheel nut. Neither the BMW hotline still at RUD hotline I got a satisfactory answer - you me each pointed to the other party. Nowhere are the exact dimensions of the sleeve are communicated, and also of the car manufacturer can use a notify the exact dimensions.

The Centrax is supplied with two sets Radschraubenbefestigungen and valve caps, which in wheel bolts M10 and M12 (wrench size 17 or 19mm) to fit, as long as the rim hole 23 and 27mm diameter. My Winter rim supporting this, and so the sentence was ordered chains.

The chains come in a compact pouch, in which the chains and the mounting hardware are included, including gloves. Quick look at the table, because you have up to four of the so-called shortener, which are pre-assembled at the factory, remove depending on the size of the wheels. In my wheel size, it was a. This is very simple according to instructions.

The mounting of the mounting sleeve is very simple. Then the chain on, align spring steel arms and engage the lock release lever on the bolt, and fasten by turning knob. When starting up then the chain moves alone altogether. Could not be simpler.
