Wildpeaks at3's load rating and price

So I got almost 50k on my stock tires and it's about that time for me to get new tiresafter searching to The forum I've decided to go with the falken wildpeaks at3's but some websites have a load rating like E, P, SL, LT ect and other sites have load ratings of 115t or 116t so it didn't really understand that and also wondering best place to get the best price for them?

 

If i'm not mistaken (feel free to correct me). Passenger tires (P) have different load ratings, which are Standard Load (SL) and XL. For most the passenger rated tires will do just fine and not hurt MPGs that much since they aren't as heavy as Light Truck (LT) tires. The LT tires have different tire load ratings, ranging with letters, C, D, E.

As for best price, I see people wait for ebay coupons or things like that. I got mine installed through Discount Tire. $540 for all 4.
