Re: 2011 gc qt1
If you can get grip from the stock rubber, you should be able to get through more than the 8" JGC ground clearance (not QL) in fresh or soft snow, and considerably more than that with snow tires or AT rubber. With grip, even a heavy SUV can push, float up and down, or surf, in soft snow if you let her run a bit.
In general, the only snow conditions greater than the JGC 8" clearance you do not want to test, is wet then frozen packed snow cut by deeper, older tire tracks on either side usually left by big rigs. These conditions can set up like concrete and can either leave you swamped to the belly or cause damage to the undercarriage.
