That is a pretty small truck. A problem with pickup trucks is they are too light in the back and have no traction on the rear wheels.
A couple of bags of coarse sand and a shovel will likely do more to get you unstuck on icy or snowy roads than chains.
The sand should be in bags that keep it dry, if it gets wet it can freeze. A bit of salt in it can prevent that too.
The shovel can dig you out of a snowdrift, spread sand and if you do get stuck on ice it will chip the edge away from the little hole you melted in the ice by uselessly spinning your tires..
Snowtires are a help, If you need them get the all-season radials. They look just like regular tire but are more grippy.
A lot of the people with small trucks use mud and snow tread tires all year here.
