How do I BBQ a tri tip?!
Answers: I have a regular coal weber, i want to cook this thing up now!
My favorite way is to use an 18" kettle BBQ (your webber is perfect). Use the indirect cooking method, and sear the tri-tip until browned on all sides, then move over the drip pan. Take an aluminum can, cut off the top with a scissors, fill with water, and place over the coal side of the grate. Put lid on BBQ and cook approx 45 mins for a medium size roast. Mesquite wood chips soaked in water are optional, but do add a delicious flavor.
You can season it with back pepper while cooking, but don't put salt on it until it is almost done. Salting beef too early causes the delicious juices to move to the outside and run off, resulting in a dry steak.
Next time maybe try marinating it in Wish Bone italian dressing overnight in a zip lock. Just pierce it all over with a fork and toss it in the bag with the dressing, then pop it in the fridge. Never use a marinade with sugar or corn syrup in it. It will blacken really bad. Another killer seasoning is called "Santa Maria Seasoning".
