Be sure to check the manufacture date on the tires. If older than 4-5 years and TT has been sitting, change them before hitting the road. A lot of us recommend the Goodyear Endurance trailer tires, they are US made and tow and track good. Tires are not the place to save money.
Also look around the various forums for helpful hints with a TT. Or ask here lots of good input.
