I have a 2000 dakota and it came with 31 x10.50 -15 from the factory. I don't see any clearance issues with what you're looking for.p-metric will be a little cheaper, and might ride nicer, The lt's will probably last longer,plus if you live in a pot hole area,they will handle those better,save the wheels from getting damaged.The lt's are slightly heavier,but I don't think that you will notice any mpg difference. you might need someone with a scan tool to recalibrate speedo if you change sizes.
