If you have them mounted on stock rims, you'll have to run lower pressures to get even wear. I run 42 (front) and 32(rear/unloaded) with 295 Toyos and stock rims in order to get semi-even wear. I know that the BFGs have stiffer tread plies so they might stand a little more pressure than the Toyos. I'm contemplating going to a 9" rim in order to be able to air mine up for better fuel mileage. At the current price of diesel, every little improvement will help ofset the cost of the new rims.
