I had the same problem trying to find the intro forum. I purchased my titan brand new in May, and have been a member since yesterday trying to find some good advice for my truck. I eventually wanna go with 20 inc off road tires and bigger wheels. Not too big, just aggressive and still good with lots of on-road driving. I am going to start with some mods to give me some more power. I have been thinking cold air intake and catback exhaust. This is my first pick-up truck and I wanna do everything right.
