Chains on Brick/patio tile = Scratch if don't spin??

My experience comes not from running chains but from working around tile. The focused pressure from a hard source like chain would concern me. You may scratch your tile. A greater concern would be actually breaking the tile. You have a very hard and non-pliable surface at a very low temperature which could make it more susceptible to breakage. If there is any void under one of the tiles this chance is multiplied.

I hope you get responses from some who are already experienced in doing just what you are thinking of doing.:dunno:

Two comments that offer neither proof, nor 100% confidence:

I ran a JD 445 with chains for 14 years on a very long driveway and a very small brick turn-around area. If you are really talking red brick made of baked red clay, they are too soft and will take marks even from just driving without spinning. And as noted, if any of the brick are even slightly uneven, from frost heave or what ever, there is a risk of breaking them. Just driving over brick will apply enough pressure on the chains to make small chips at the edge of each brick. Over time they will show. On the other hand, if you are talking about concrete pavers, designed for paving driveways, I suspect, but don't know you would be ok. I also have a flagstone parking area (had two kids with cars at the same time and needed to keep expanding my parking areas and had these flagstones stacked in my woods) and never made a mark on them with the 445 and chains. Their surface was plenty hard, and did not mark.

Point two: I relate to your issue with the front wheels dropping of the low side of a driveway and the combination of weight shift and mini-ledge making it difficult to back up over the edge. My experience, even the chains will not always solve that issue. You will find yourself either spinning the chains, or climbing off and push/lifting the front over that edge. FWIW, I finally solved that nagging issue with the fulltime 4WD of my new x748.

Good luck, and good preparation to think of this and ask before taking the next step.
