Getting the tongue weight correct is very important. I used the āBergstrom Method.ā

You should be able to estimate the total weight of the trailer and car, and anything else you put on the trailer. But using truckstop scales is better of course. Iāll take a wild guess, just for the discussion, and say itāll be around 4,500 lbs.

You then need 450 lbs. on the hitch/tail of the tow vehicle. Have 450 lbs. of friends stand on the rear of the tow vehicle and measure the height of a known part of the tail of the tow vehicle, to the ground directly below it. Write down this measurement.
-
Hook-up the trailer and drive the racecar forward until the tow vehicle tail drops to the measured height.
-
Mark the spot where the racecar is now sitting on the trailer and you will have the correct tongue weight. Put the car in this same spot everytime and youāre good.
If you donāt have enough tongue weight, the trailer will sway and will pull the tow vehicleās tail from side to sideā¦until you get it stopped. This is very bad and can result in a huge crash, for you and possibly other drivers.
Get the tongue weight correct and you should be able to drive at normal highway speeds very comfortably.
Also, consider a weight distributing hitch. It consists of a larger hitch that locates two longitudinal bars on each side of the hitch, that also attach to the side rails on the front of the trailer. Some people think these are āsway barsā but they really distribute some tongue weight to the front of the tow vehicle by āpryingā the trailer hitch upward, which lifts the tongue. This helps maintain proper tongue weight but keeps the rear of the tow vehicle from sagging so much from the tongue weight. Youāll see them on camper trailers.
A weight distributing hitch is expensive but I used one for years and it was a good thing. Normally, they are used on larger/heavier trailers but I towed my race cars on an open steel trailer with a Mazda MPV (the old RWD version rated at 4500 lbs. towing) and it worked great. It also keeps your headlights from aiming up and into other driverās eyes; and we do tow at night alot. If your tow vehicle can easily handle 450 lbs. of tongue weight (a large SUV or truck), without sagging down, use a standard hitch.
All the other advice here is good, especially the part about having a spare. In 18 years of club racing, I have changed about ten trailer tires on the side of the road. We had one blow on the way home from Summit Point Sunday. It didnāt come apart from low air pressure/overheating; the sidewall blew out.
Good luck and read every post here three times.
