No, the Prado came with 4.88 gears. That is an incredibly low gear set. So, a slight increase in tire size is not going to make a drastic difference as it would on a higher geared diff. And, if you have done any tuning on your truck, it will be no comparison at all to even a stock tired Prado.
The difference in that is night and day. The truck labors under even stock tire size uphill with the stock tune. I have driven mine with both stock tire and 33" tires at stock tune. There isn't really a noticeable difference between the two. Still just slow. And, if you tune the truck, it will make you no difference.
