I run the missions for mostly asphalt and Continental TKC 80’s for offroad. You may get away with less aggressive tires but why risk crashing if a more aggressive tire could prevent that?

 

I did the Nor Cal BRD last year with knobby tires and glad I did for much better traction. You usually are only on the street for small sections and like @dallas said why risk it. My normal riding is all street with a good amount of freeway so I took off the knobby and put on street tires which handle much better and next year when I go do another BRD I'll put the knobbies on again as they have lots of life still in them. Use the BRD site to read up on the route and suggestions it is very helpful. The Nor Cal is easier for a bigger bike than the So Cal, NV and AZ routes I believe.

 

As someone who bought their AT for the purpose of riding BDRs (and who bought a dirt bike for the purpose of training to better ride off-road), I hate the idea of having to buy a 3rd bike. I ran the SD-BDR-X on Pierelli STR Rally tires (70/30), but the conditions were perfect.

I agree with you on knobies. The AX41s or Trailmax Raids interest me. Likely the AX41s because I can install them myself.

 

AX41s are good on the road and on trails, especially dry and stony surfaces. Any looseness on the road is easily dealt with by the AT traction control. They do fill with mud if it is thick sticky clay, but then clear quickly once out of the mud. Prolonged stretched of mud might be a problem.

Here's a fairly new tyre, with deep tread, after coming through a muddy trail in South Warwickshire, England.

 

Try a search this has been discussed ad nauseum!

 

My choice has been 90% dirt (Motoz) tires. Can't have too much traction off pavement.

 

Hey Tiger…kiss off!! If you don’t have anything fresh to add just scroll on by, why be insulting? Tire experience can be like choosing oil, but I was specific and explained exactly what I wanted. Info related to BDR and full knobby. Thank you to the forum for the remaining thoughts, I appreciate you time.

 

I use the Dunlop Trailmax Raid and have ridden most of the Az BDR and many other areas off road in Az, they are great in the gravel, sand and rock, and ok on road, but I got them for off road, but I'm not sure they will last much more than maybe 3k, they are wearing fast, but grip great in the Arizona dirt/sand.
