i think whoever put your nitrogen in didn't purge the air well enough.
everett is correct. To expand a little. Nitrogen will expand as regular air will. The slight advantage nitrogen has over air is it takes longer to leak out of your tire and it doesn't create as much heat inside your tire and thus there is less condensation inside your tire.
The tred on the tire should have deep rivets and stuff to dig into mud and get traction
nicely a much wider tire gets much less traction in snow than a slender tire via fact the extensive tire floats on the best and cant dig down for traction like the slender tire. I run prevalent width dirt tires on my vehicles on the iciness and get super traction in deep snow yet very unfavourable on ice and packed snow. The final time i bought mudders for mine i went with some hercules path diggers which have been studdable. It fee me approximately 80 dollars to stud all 4 even yet it became nicely worth it. Ice is not a situation. of course i now have 2 contraptions of tires mudders for iciness and mudders for summer time. they're 265/seventy 5/sixteen's I actually have a collection of 275/50/20's on my different truck and it truly is valueless interior the snow they're too extensive.
Carefully read the sidewall of the tires and look for the letters UTQG followed by a number. Mud and dedicated snow tire have no UTQG wear rating number which means they wear-out very quickly on bare black-top or concrete roads. If you had listed the specific brand and model tire in question, we could have answered your question flat out.
