Copper Canyon has 15 inch wheels - tire options?

If you have the standard aluminum Keystone 15" wheels like I had on my 2010 Sydney fiver (12,000 lbs), the best tire in my opinion would be Maxxis 22575R15 load range E. I switched out the junk load range D tires that came with my 2010 Sydney anf upgraded to E's. It was the best upgrade I made on that rig. LTs were out of the question with 15" wheels.
I put LT tires at the dealer on on my new 2013 Sydney as it came with 16" wheels. The tires that came on it were junk as well.
