Hi,
We have a 21.5' Travel Trailer, with a GVWR of 4769. We are getting ready for our first camping trip of the season, and I'm looking for a recommendation of how many pounds of pressure to carry in the 5 tires, 4 on the ground plus a spare.
Here are some stats on the tires: Brand is Karrier, "for Trailer service only", Tubeless radials, Size is 205/75R14, Load range C, Max pressure, 50 psi cold, and yes, made in China. The TT is only a year old now, and these are the OEM tires. I understand the principle that more pressure in the tires means cooler running temps for the tires, but the trade-off is a rougher ride for the TT and its contents. We travel only 120 miles each way throughout the summer to our camping spots where we stay 3 or 4 days, then return. The roads are pretty much all paved and of good quality. However, we live in Phoenix, AZ, and tow to the high country, so at the lower elevations in summer, temps can be 100 degrees or more, though we leave early enough going or coming to avoid towing in over 100 degree temps.
The tires are all currently sitting at 37 psi cold. I'd be interested in any recommendations as to what pressure to carry in them throughout the summer. Thanks much for any input.
