Trailer tires, Time to replace. Suggestions Options

[Krieger]

So my twin axle 7000 lb. open trailer is 8 years old and the date code on these tires will be 9 years soon. I know I must replace these tires. I completed inspected each tire every time I used the trailer. Maybe around 6-7k miles total. The tires look like they are maybe three years old. I think these were bias ply. They are Hi Run LQ 229 205/75 D 15. I just found these online for $69 each. For all I know Hi Run are crap tires now. Should I just go to COSTCO or Les Schwab? Does anybody have brand recommendations? Radial or bias ply?

Thank you

Having towed race car and horse trailers for more than 24 years, I am a believer in quality trailer rated tires that are sized for your load. Load range D (65 psi) or load range E (80 psi) are what I use.

Additionally, I strongly recommend a TPMS system for your rig. A slow leak will heat up the tire and eventually cause failure. TPMS saved me more than once. They are not terribly expensive and I put sensors on the tow vehicle and the trailer.
