Update on Dunlop Roadsmart IV tires after 4000 miles.
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.

Mileage at 111049 - Cortez, CO
4049 miles on tires
Front - 5.0, 4.0, 5.0
Rear - 7.0, 5.0, 7.0
Road conditions - the last 2000 miles were on mostly 2 lane roads. 350 miles in the South Dakota Black Hills, 300 miles crossing plains of Wyoming and 1350 miles in the canyons and on a few of mountain passes in Utah. 400 miles was on fresh asphalt which tends in accelerate wear on tires. The roads of Utah were mostly sweeping curves on 600 miles and tighter curves on 300 miles with the remainder being straighter roads.
Speeds - the speed limit in Wyoming and Utah is 65 or 70 on 2 lane roads so the majority of miles were run at 65 - 75 mph. Most curves or corners are rode at an average of 15 mph over the posted number.
Temperature/Weather - ranged from 45 to 95 with the majority of the time in the high 70’s to mid 80’s. I had only 5 miles of rain and 15 additional miles of wet roads so cannot comment on the tire in the rain but hope to find a few hundred miles before the set wears out.
Darrell’s comments - tires continue to display a round profile with zero cupping on the front tire. Handling remains as it did the first 2000 miles so very positive. With the Roadsmart III I would wear out the front tire before the rear and I am sensing that will not happen with the RS IV. The next 1500 - 2000 miles over 8 - 9 days will be spent in the Colorado Rockies so will get a good feel of handling and wear on tighter curves
