I have a '00 150 4x4 with stock rims. Looking to purchase 315/70-16's but need to know how much trimming to do/and where the trosion bar is so it can be cranked. Or should I go with 285/70-16's. Does anyone have these set ups or ones similar?? Pro's-Con's??? Any info would be greatly appreciated.

 

Cons are that the stock rims aren't as wide as we would like them to be for 315s, but the pro is that you have 315s!
