I'm a newbie to the site, and just bought a 16 foot Thor Wanderer. My question is, if the TT tires and the TV tires are not at max air pressure, would it cause major bouncing. On way home from dealer, handled beautifully except for bouncing. Trailer tires were at 50psi, max is 65, and truck was at 37psi, max is 44.

twwpalmsprings,

Welcome to iRV2, we're really glad to have you here as a new member and are looking forward to reading your posts about your RVing experiences and adventures. You'll find a great bunch of folks on this site who are very knowledgeable of RVing, the rigs we use, and the places we go in them.

As you'll see, they're eager to help and share their knowledge and experiences with others.

I doubt the bouncing you are describing is caused by tire inflation, your tires should be inflated to the amount of pressure as indicated on the trailer's placard and the truck's placard. You're probably experience what some of us refer to as 'Freeway Hop'. a bouncing action that gets started due to the sections of pavement being inconsistent from each other.

It's a function of speed, pavement section size, trailer length, and tow vehicle wheelbase. The suspension starts into an oscillation and just keeps bouncing until something changes to stop it.

Adding shock absorbers to the trailer and stiffening the tow vehicles rear suspension
may help some but it's tough to eliminate it entirely.

Again, welcome to iRV2, we're glad you joined.

Since you were on your way home from the dealer the trailer probably didn't have a load in it, like water, propane, etc. I suspect that once you've "loaded it" with some fresh water and your "stuff" for a trip, you find the added weight will have a positive effect on eliminating the bounce.

Do you have a weight distribution hitch? You may have to adjust it for either more or less tension on the bars, as well as determine what the maximum weight you can load the trailer with before you "overload" your towing system.

Good luck.

Thanks for the replies. Yes, I do have the Equalizer Hitch/WD. I go back to the dealer soon, and will have them adjust it if needed, after we go for a test drive. I will have my tires at the proper psi this time as well, to see if there is a difference. This is all new to me, I feel like I'm in over my head. At least this forum has useful information to learn/help.

I think you'll find handling more precise if tires are aired to sidewall maximum. It's worth a test, If you don't like it you can return to previous pressure. 90% of tire failures are caused by under-inflation per industry findings. ST tires are speed rated for 65 MPH. Goodyear says for each MPH over, rated load must be reduced by 10%. I too welcome you to the club! No-one here knows it all, however, together we do know nearly all.
