Well i generally have alot of people riding with me I live in a college house and inevitably i have 8-10 people trying to cram into my car so a spring upgrade might not be a bad idea.
As for the tires I probably wont be driving the truck much in the winter if at all i have a celica I use for snowboarding and long distance driving since getting 15 miles per gallon really chokes my bank account. I have 36in super swampers on there now but you would think they were racing slicks. I'm thinking of downgrading to 35's. I really want a sensible tire but i dont want to lose the look it has right now.
