275/55-20 Toyo Open Country H/T on the wife's truck
285/70-17 Nitto Terra Grappler G2 on my 2500HD

 

275x45x20's Iron man's they were $500.00 mounted and balanced. They Handle well and they seem to be wearing well.

 

275/45/20 Nankang SP-7 from ebay. Were 382 shipped can't beat that man lol

 

275/60/20 Michelin LTX Premier's. Not cheap but I have about 40k on them with half tread still left on a heavy nnbs crew cab. The only problem them is now I don't have a good excuse to get a different size/style tire.

 

got me 285/50/20 Nittos...they dowell, smooth ride but would go smaller next time maby 18's for my v6 that is...

 

305/75/R16 Cooper STT Pro mud tires

 

I just picked up 275/55/20 Michelin Defender LTX MS. Also not cheap. I'm hoping they work as well as my last set of LTX MS2.

 

I can't imagine them working worse than your first set.

 

Everyone speaks highly of the Hankook RH06 for traction. Not to mention, people are getting great mileage out of them.

 

I have a spooled rear end, and I run the goodyear fortera HL's in 245/65R17. They seem to grip pretty good for normal street driving, and the best part is that they don't squeal when turning.
