Your tire shop clearly thinks all vehicles are Corollas.
You'd be well advised to never return there. 38ish for Prated (like yours) and 40-50 for LT tires would be reasonable on these trucks.
Agreed.
I always purchase my tires online, for about 25+ years. So I find a tire shop to do a mount/balance economically.
I see you are in SoCal. When I lived in Orange County I would always use Tucker Tire. They were great.
The shop I use here in TX is a large outfit, NTB. They did do a good job on the oil change (semisynthetic) when wallyworld (never go there again) could not get the oil filter off. What a wuss.
