I pulled the rv-12 out of the hanger after warming it up with my pre-heater and taxied over to the fuel pump. Took about 10 minutes to fuel, taxied back to my hanger to get arriving passenger. In the meantime, the wind started gusting and blowing snow off the drifts. Shut down to load passenger, but we decided it was starting to gust alot worse than expected, so we hooked up towbar and tried to put it back in the hanger, but 1 wheel was frozen. It appeared that some blowing snow got inside the wheel well and froze between a brass bushing and the inside of the hub. There is only about 1/32 " gap, but I couldn't budge it. Luckily I was near the hanger & my 100' extension cord and salamander heater, finally got it freed up & back into hanger. My A&P told me I probably would have blown a tire if we would have flown that nite. I had removed the wheel pants to avoid a slush build-up, but now the hub is more exposed to blowing snow. What do other pilots do besides only flying above freezing ? Thanks
