Re: P245's for my splash?
I would go with 31x10.5 R15 for your Ranger. The 31's will fit with only minor rubbing with the steering at full lock. A passenger tire like the P245's have very flexible sidewalls making it kind of "squishy" around the turns. A light truck tire such as a BFGoodrich 31x10.5 R15 All Terrain has nice stiff sidewalls and makes the truck handle well on and off road.
I've been running BFG's for years and have yet to have one complaint about them. Can't go wrong with them.
