Long distance trailering

[Crazy Dave Condon]

Kerry;
Long distance I would suggest a tire pressure guage for checking the tires and fill before the trip. Fill cold.

Those are good ideas too.

60 mph generates a lot less heat in the tires/bearings than 75mph

I put my hand on the tires and hub after 50 miles. then recheck when fueling.

The tires and bearings may be in perfectly good condition, but just be prepared... after towing a few miles, get out and feel the bearing hubs... if they are hot to where its even slightly uncomfortable lay your palm on them, you have a problem... and if they are cool, check them in another 50 miles.... if there is no change, you can stop worrying about the bearings.
But make sure the tires are fully inflated to their max pressure... and check on them periodically to insure they are still in decent condition...

This is probably the most important post regarding what to pay attention to. Heat in the bearing, or heat in the tires will tell you nearly everything you need to know while driving.

Trailer tires are only good for 5 years, even if NOT USED! ...

This discussion comes up on the RV forums regularly. 7 is more accurate according to the tire manufacturers, although some state even longer. It would be best if the previous owner will tell you how often it was driven. Tires are designed with special oils that work themselves to the surface to prevent UV damage, and preserve the rubber. If the tires sit for an extended period of time, these oils do not get worked around to the surface, and the tire will dry rot. Nylon belted tires will last much longer than steel belted tires, as it is difficult to get the rubber to bond to the steel. Steel belted tires are much more prone to tread separation. Yes, they are better for road hazard protection, but do not tolerate heat or age as well.
