The 315's will be fine on the front, but the spacing required so they don't touch in the back may not be there.
You can play with air pressure to get a better ride. No reason to blow them up to the max. But you don't want them underinflated either.

Check for clearance with the leveler pads with the wheels at max turn. My right tire will contact the pad if I turn the steering wheel to the stop.

I switched the fronts on my 06 to the 315s, and loved them. No benefit with them unless you switch to wider wheel, because they have the same weight rating as the 295s with the factory wheels and that means you run them almost at max pressure.

With the wider wheel, you can drop pressure to about 110 lbs, and the difference in ride is something to sing about!

I had no issues with their greater diameter or width, but you sure have to be certain the tires are straight ahead when you drop the airbags to level with the jacks.

I believe the new wheels Spartan factory used for me were 9" wide. They were using them with 315 tires for some Entegra models at the time.

Is there a sticker with recommended tire pressures in the coach anywhere?
