I am considering going to 19.5s on my 3rd gen 3500 4x4. Looking for higher weight carrying capacity than I can get in the 17" wheel and tire combo. I am currently running Michelin LTX 2 and am very pleased with the traction I get in wet, snow and ice and am very concerned in finding something in a 19.5 traction tire that will at least provide a reasonable amount of traction. I am thinking I need an open shoulder style rather than a closed shoulder style.I am considering the Vision 81 machined aluminum wheel which is rated for 5k pounds. Looking at several brands of tires (Double Coin RLB1, Cooper Roadmaster rm253, Toyo 608, Yokahama TY303, Hankook DH01) to name a few of the more reasonably priced 245/70/19.5. Anyone had any experience on 19.5 traction tires (good or bad) that you are willing to share. What are good brands to consider. Most truck tires are getting pretty high mileage (I am told 80k-120k) so I would expect the tires to time out from age rather than wear out due to mileage.I know the sidewalls will be stiff and the ride will be more rough when I am not loaded but I am hoping to stay away from tires that's sing too much or are not reliable.Any input?

I still curious about the performance wise on dirt like AH64ID would be doing plus the life span.

I read these posts last week, about you and others wanting to go to 19.5" wheels and tires.  I had been looking into them myself and have a website all of you guys and gals should take a look at.  There is a lot of information about changing to 19.5" wheels and tires, including what the affects will be on the Speedometer/Gearing and such.  Take a look.  Ricksontruckwheels.com.  Hope to talk to all again soon.
