Riding a big bike anywhere but pavement can sometimes be a little daunting, with all that added weight you really need some grip.
I have tried a bunch of different tires on lots of different bikes and wrote a very detailed article about that a while back - ADVENTURE TIRES – ‘MY PERSONAL EXPERIENCES’
The one tire that's not in that review is the MotoZ Tractionator ADV front for a big bike, in a 19 inch, the tire shown below.
This tire I found to be confidence inspiring, in the dirt, and also have great grip on the pavement. A very good all round, classed as 25% Road – 75% Off-Road it does what it says.
Don't think that due to the extra grip you will get crazy distance if just used on the pavement, this WILL NOT happen, it will wear faster than expected, use it where it was designed for primarily in the dirt.
The thing you will notice straight away is the amount of tread depth for a big bike front rubber, set your air pressure accordingly and enjoy the added grip and confidence it will give you.
