its called radial pull, take it back & have them replace the tire, very common
He can get the Toyo MTs replaced 100 times and still get that radial pull, specially when going with the larger size Toyo MTs.
Ive ridden on several trucks here with the toyos, all with the radial pull, some try to reduce this pull with an alignment, it will not solve it 100% and you will have your truck out of alignment in order to make it track straight.
Do a search here on radial pull and you will find this true specially on larger solid front axle trucks, your cheapest solution is to get a 1 degree offset balljoint to cure this radial pull to the right, I was gonna do that, but I will get a nice steering stabilizer shock from Kore which helps eliminate this radial pull.
