Although this thread stopped in January, the winter season is coming up fast.. On my 2013 AWD, we put snows on right away for the first year, I did not like the look of the stock continentals, so we placed BFG winters on. The first problem was finding a set of winter rims, it turns out that GM changed the spec from 5 by 100 mm bolt pattern to 5 by 105mm. Hardly anybody had rims that would fit. Next came the tires, the stock size 16s on the trax are not a common tire so to get winters we had to use 215 instead of 205. These tires were great and in the Heavy snow areas of where I am from it made a great difference. The Encore would be the same.
If anybody is looking to put winters on this year, also change your wheel nuts, 2 winters of ours and they were a rusty mess. This season now that we have a 2015, we are now going to have to add TPMS sensors to the steel wheels.
In 2017 as this forum mentioned, The Trax will have a refresh, for a nice Trax look, just google, the Russian Niva, its a Trax but with Bush Bars, Winch and other essentials. It looks lifted by 4 inches as well.
