You want to go with a lower offset when upsizing you whel diameter. An 18-20MM offset should fit fine with no rubbing issues. 265-35 is about as big as you can go without rubbing issues. I'm looking to upgrade to 22's from 20's in the first half of 09.
I have 22's on my Dakota right now and being that it is a heavier vehicle the ride is very smooth. 265-40's on it.
