I just put on the Bridgestone Dueler A/T Revos size P255/70R16 and LOVE them! The ride is greatly improved and I have not had any rubbing issues yet with the inner fender wheel wells (but I suspect if I offroad this CRD than I will have some rubbing). I used to have the older style Bridgestone Duelers on my 1989 Chevy Pickup Z-71 before I sold it. They had 102,000 miles on them before I had to replace them - but they were an LT rated tire with even more tread depth than the P rated ones I just bought. The key is that you must keep the tire pressures up a bit above the vehicle recommended (I run at 38-40 psi cold) and you MUST rotate every 5000 miles - NO EXCEPTIONS.
I've had good luck with the Bridgestones in the past and am giving them a try on my new CRD. There is a $75 mail in rebate going on right now through October 15 if you have a set of 4 mounted and installed by an authorized tire or service shop.
I traded in my 4 factory tires at 588 miles (kept the spare) for a $300 credit and was out the door installed for $260. After the rebate I'll be at $185 for the upgrade. If you are worried about rubbing and do trail riding, stick with the P245/70R16 size as this is nearly the same diameter as the factory P225/75R16 but only 0.9 inches wider. I use my rig for mainly highway use and construction site inspections in the mud, so I'm only off road for a very short time.
