What Should Trailer Tires be Inflated To


My Tab 400 campers original tires are load range C with a max inflation of 50 psi. The trailer rating sticker gives an inflation of 50 psi. I have replaced the tires with Goodyear Endurance tires load range D with a max inflation of 65 psi. What PSI should I inflate the new tires to? 50 or 65psi - or somewhere in between?


Expert Reply:

When inflating trailer tires the recommendation is to inflate the tire to the max tire pressure listed on the sidewall when the tires are cold. So if your max pressure is 65 then that is what you would need to inflate to when cold. The increased pressure when hot is normal.

If you don't inflate to max pressure the tires will not get their full capacity and heat will build up which will cause premature failure.
