Traction track questions

Was watching a Nathan Mueller video yesterday, he spoke very highly of the X Bull traction tracks. I need to get some, and have some questions.

1. Does storing these exposed to UV significantly shorten their life? I’d likely throw mine in the topper for most occasions, but would also probably store them on my roof rack as well.

2. Bad reviews. So folks not know how to air down and not spin tires? I see a lot of bad reviews because the traction nubs burned off. I’m assuming 4LO is ideal for using these?

3. Size. I see different sizes, X Bull has a couple. So I assume I want the biggest possible given the weight of a Tundra?

TIA.

 

Depending on rim and tire size, and rim style you might want to consider strap on traction blocks. Storage might be less of an issue. Pretty effective too. Just need to have the abilty for the strap to wrap around and not hit the brake calipers while in rotation.
