Trails and snow shouldn't really be a concern...trails are slow And you generally drive slower in snow anyway.
The main issue is the ability to go up hills on the hwy...you'll be a dog, especially if you've got an auto, but you'd be fine in town or in trails.
I run 35's on my 99 2.5 but rarely ever go on the hwy...only when going to a trail. I also run 4.88s and have a manual so it's doable.
Good luck with your decision
