Familiarity: I've put it through the wringer
If you have a 963Pro Tire Mount Thule, this looks like it was built for it. However, the 963 has smaller diameter metal compared to the Tram. Where the tram was built to carry 6/4 skis/boards, if you use it with a 963, you can only carry 4/2 skis/boards. Consequently, there is a bit of bounce while moving with a full load. I don't think it's going anywhere, but it makes me keep an eye on it. For the money, I would have expected sturdier support. Arguably, it could be the result of the max load of the car tire mount. Either way, for what I need, it does the job and looks pretty darn good. I didn't want a roof rack on my 2013 Wrangler and any hitch mount won't clear the spare tire and tailgate--a pain when suiting up for skiing and you need the tailgate open. Only option, mount to the tire so everything swings out of the way.
