I haven't heard of anyone running 315-30-20, but lots running 315-35-20.
Aspect ratio is just that - a ratio. A 315-35-20 will have a 28.7" diameter, while a 315-30-20 will have a 27.4" diameter. You lose almost 3/4" of sidewall by dropping to a 30 series.
The stock rear 295-40-20 has a 29.3" diameter. Going to a 295-45-20 will get you to a 30.5" diameter. I don't like the tractor tire look, but others are more concerned about the ride quality and live with it. I've never had an issue with ride quality.
Tis better to have loved and lost than never to have loved at all
