i have 33x12.50 swamper radials on my xj right now. compared th the 33x12.50 bias swampers i had on my cj the radials are smaller (width and height), much quiter, and wear about twice as slow. they still have the agressive swamper tread and behave much better in rain. if you need an agressive tire but still drive on road a lot, i'd recomend them.
