J12 snowchains?

[peeaa]

Two questions:

1. I have J12 VX (5 doors, original springs and suspension) with BFG AT 265/70R17. Has anybody used snowchains in J12 with this tyre size? So is there enough space for chains or should I just have the original tyre size 265/65R17?

2. Recommendations for chains? Make, model, size?

According to the manual the chains should be used on rear wheels only. Different opinions?

Thanks,
