I have a 2004 Sunline Solaris T2475 with maxfli st205/75R15 tires. What is the correct tire pressure. Thanks
 
Tire Pressure

I'm not familiar with your trailer's brand of tires but the trailer does weigh 5000 pounds, resulting in a load of 1350 pounds per tire. A saftey factor of 20% would be wise indicating a requirement for 1620 pounds load per tire as a requirement.

Safety margins are wise because trailers are never equally loaded from side to side due to the trailer itself and equally due to road conditions, slopeing roads, bumps, etcetera.

I use Goodyear Marathons and in your size range 50 pounds of pressure would provide a load capacity of 1820 pounds of capacity per tire. As a result I would guess that you need 45-50 pounds pressure. I would suggest that you enter the full name of your tires and look for the inflation chart.

If you list the tire manufacuter I would be glad to help.

Good luck,

Norm Milliard

This chart may be very helpful. Note that there are different optimal pressures for B and C rated tires.

IIRC, all tires have the maximum recommended tire pressure (COLD) and (most of the time) the load rating on the sidewall. That's where I look.

My trailer has the same size tires as fiveaday's trailer. 50 PSI COLD is the max pressure listed and that's what I run them at. I want the most load capacity I can get with this heavy coach. :wink:
