I've asked the same question for the past two years. I couldn't find a set of chains or cables that fit the 20" tire size. Last fall I went to Les Schwab and asked if they had anything that would fit. They finally got the size for the tire. Their tire chain specialist looked over the vehicle and told me this is a common issue with many new cars. He did not recommend putting their chains on the front tires due to clearance but said they would fit on the rear tires without a problem. He said since the car is AWD, you probably won't need them in most situations, but if you did need them, definitely put them on the back. Their chains are a lower profile chain and pretty easy to put on. I did use their chains on a 2006 Murano AWD and they worked fine. Whats nice about Les Schwab is that if you don't use the chains, you can return them the following Spring.
