Question:

My trailer 2018 fr cruise lite 230 bhxl came with castle rock 205/75 r14 8 ply load rated D , nitrogen filled tires. The tire says that max pressure is 65lbs but the tires are filled to only 50 lbs.the trailers dry weight is approx.4950lbs and max is about 7500lbs . I was wondering if you have any info. On these tires, and why they seem to be under Inflated? Thank you

I don't have any information on your 8 ply tires. Our 6 ply rated Castle Rock ST205/75R14 Radial Tire w/ 14" Condor Aluminum Wheel - 5 on 4-1/2 - LR C - Gunmetal # LH84VR have a max psi of 50 and are inflated to 50.

I can confirm that your tires that state 65 psi are underinflated at 50 psi and will need to be filled to your max psi when filled cold for proper function. Many tire shops will have the nitrogen available to fill your tires to their required max psi when filled cold.

Driving with under inflated tires can cause uneven wear, lack of traction, overheating, and even blow out. I highly recommend you get your tires inflated properly as soon as possible. You can add normal compressed air to your nitrogen filled tires, it just be as consistent as Nitrogen. Even Nitrogen filled tires need to be maintained, they just won't fluctuate as much as regular compressed air with temperature changes.
