My first report to Dunlop on the Roadsmart IV tires.

Dunlop Roadsmart IV Tire Performance Update
Motorcycle - BMW 2016 R1200RS
Darrell Penning Recording Data
Tread depth is measured in 4 spots in each of 3 areas around the tire in the order of 1” from left sidewall, center, and 1” from right sidewall. Depths listed are in 32nd of an inch.
Tire pressures are check and adjusted if necessary every 2 - 3 days regardless of miles rode. Pressures are checked in the morning before riding so tires are cold. Pressures are maintained at psi 38 front and 42 rear using a calibrated dial gauge for pressure checks.

Collection of Roadsmart IV Tire Information
August 12, 2020
Installed new tires at Moon Motorsports in Monticello, MN, a Dunlop Pro Dealer
Mileage at 107,000
Front - 5.0, 5.0, 5.0
Rear - 8.0, 8.0, 8.0
August 25, 2020
Mileage at 109070 - Whitewood, SD
2070 miles on tires
Front - 5.0, 4.5, 5.0
Rear - 8.0, 7.0, 8.0
Road conditions - generally flat with some sweeping curves in the Black Hills of South Dakota and Panhandle of Nebraska as I’m riding in central plains of the US. Most miles on roads of well worn black top and concrete surfaces. 300 miles of 4 lane highways.
Speeds - generally in the 65 - 70 mph range. Maximum speed of 90 mph for 200 miles on interstates I25 and I90 in South Dakota.
Temperature/Weather - ranged from 65 to 107 with the majority of the time in the mid 80’s to mid 90's. No wet roads. Skies are generally sunny so road temperatures are warm with 1000 miles of hazy skies from the forest fires in Colorado.
Darrell’s comments - Comparing to the Roadsmart III the tires (especially the front) seem more compliant (softer feel) to road surface imperfections such as expansion joints or cracks in the pavement. I sense the bike has a sharper turn in on corners but will comment on this further after I get some time in the Black Hills this week and the Colorado Rockies a few days from now. With the high temps and sun causing warm road surfaces the tires do allow the bike to move on any tar snakes running parallel to the line of travel, but no different than the Roadsmart III. My initial reaction on tire wear is surprising considering the heat, speed and flatter roads I’ve been riding on.
