How CURT talks about trailer sway control — useful after you fix soft tires, not instead of airing up.

Towing
Soft trailer tires make sway worse. Most first-tow weekends learn that the hard way. Here is what matters: check cold pressures on the trailer and the tow vehicle before you leave, why underinflation on the trailer side feeds yaw, and how tire pressure belongs beside the first-tow and sway checklists. We teach the habit here and do not stock trailer tires, with free shipping anywhere in Canada when you shop related hardware.

How we talk about cold tire pressure before a tow
Read the pressure molded on the trailer tire sidewall or the trailer placard, then set cold pressures before the trip. Soft trailer tires flex, heat, and feed side-to-side yaw once highway speed arrives. Tow vehicle tires matter too, especially the rear axle that carries tongue weight. Recheck after the first long stop if temperatures swing hard. This page teaches the habit. There is no single PSI number for every trailer brand.
Step 1Set trailer pressures cold before you leave
Use the placard or sidewall guidance for that tire.
Step 2Set tow vehicle pressures for the load
Rear axle tongue weight is real.
Step 3Treat soft tires as a sway cause
Hardware cannot fully save underinflation.
Step 4Recheck after big temperature swings
Cold mornings and hot afternoons both move the gauge.

Stop Trailer Sway in Its Tracks
Why sway gear is a second layer — soft trailer tires still have to come up to the cold sidewall number first.

Level attitude from a correct ball mount keeps load even across tires — soft rubber plus a nose-down hitch is a bad pair.
