whats the best way to keep the tires from going bad when sitting along time? thanks

 

Buying new ones . The best you can do is keep them from sitting in water, bleeding down during storage, keep the tread face supported all the way across(some people park on planks). It wouldn't hurt to put a tire cover on them, as long as it's not air tight.

 

I'm a firm believer of parking trailers on wood planks. Course, the best thing for a tire to last is to use it.

 

Sorry, I'm not getting it... what does parking on planks do? You're talking about a 2X6 or 2X8?

 

Max out the air pressure and park them on air by placing the unit on jack-stands or blocks.. Spraying 303 on them will help cut down on dry rotting..
Tire covers if it is parked in the daylight..

 

a peice of mirify works good,it allows air flow we do that on our grader tires at work.

 

If the tires settle into the surface, whether it's dirt or asphalt, water will pddle around them. Some people are pretty rabid about using 2x's to park on. BIL is one, but usually uses whatever is handy, even 2x4. I've tried to get him to use wider planks, but , well, BILs. I parked in a buddies hay field last winter, and used 2 longish pieces of scaffold planking, 1 per side.

 

I would put the trailer on jack stands and store the tires out of the Sun and weather. Aerospace 303 is a good idea also. When I bought my trailer used,the tires only had 1300 miles on them. However, the sidewalls were cracked and dry rotted from being parked on an asphalt surface and not used (the ladies husband had passed away). I had to buy new tires all around

 

Got it. Thanks for the reply.

 

Getting tire covers at an RV place is a good start, keeping sun off tires.
The wood keeps the ttires off the ground and moisture. I have used treated ply wood cut 12" x 4', and also put some plastic floor matts for additional water barrier. The more often you run your trailer, the better, as the tires release compounds that help prtect them as the roll.

 

I put my trailer up on blocks for the winter--works for me.
