That is the drawback of narrow rims and wide tires. You have to run them soft to get the tread to lay flat on the road. That could get interesting in high speed (speed limit) cornering. I tried it for a week or so and then bought 10" rims. That would completely change the look of your truck though. If you like the rally wheel look then I would be inclined to leave it as is.
