Just make sure you don't price 30 inch load range C tires against Pmetric car tires. Do price comparison againt LT tires.
Usually you only want to go an inch or 2 taller at most.
Had I gone with 30 inch tires I may have seen more of a fuel economy boost.
But it was hard to argue with free tires when the P235/75R15 were failing left and right.
Then I kind of got hooked on the 31 inch tire.
