Sounds Like a Good Pair of Tires
Dunlop has had the Roadsmart line of sport-touring tires for a little while now. It had the Roadsmart III tires previously, but now it has updated the tires and that has birthed the Roadsmart IV. Dunlop will now sell both tires.
The Roadsmart III tires could provide 12,000 miles, which is 3,000 more miles than the main competition. These new Roadsmart IV (RSIV) tires should add a class-leading performance option to the mix while still providing long life. The RSIV tires can provide superior mileage for riders (up to 26 percent).
The tire compound is completely new as is the tread pattern, construction, and profile. The profiles differ from front to rear. This results in a 15 percent lighter steering on turn-in. The tread pattern is designed to provide maximum grip while also providing even wear.
The compound of the tire utilizes Hi silica X, which increases the silica content. This improves grip even in the wet. It also provides a 10 percent improvement in wet braking over the Roadsmart III. Fine carbon is also used. This increases the bonding point with polymers on the molecular level, allowing the tire to heat up quicker and more effectively.
The tires come in a variety of sizes. You can check out Dunlop’s website for more info and see if they will fit your bike.
I’ve been using III’s on my 17 R1200RT. Love them. Wish they would offer a pair for me yo try. Hard to upgrade to a more costly option when the current product was so good.
I would imagine the IV is better, but I wonder how much better really. Would be cool to do a comparison piece of sorts.
I’m looking to buy a replacement set of tires, and I’d like to buy the Roadsmart IV tires, but…
The only “reviews” I see are “First Look” reviews which are nothing more than regurgitation of the Dunlop press releases. And with the price of the IV being @ $140 more for a set than the III, it is hard to justify without more data than a press release.
We would love to be able to review all the new tires that come out but doing a proper review takes time and resources of course.
I think it’s always a good bet to stick with what you know works if you have any doubt. At the same time I did a review of the Michelin Road 5 tires last year which are the next generation of the Pilot Road 4. The PR4 are phenomenal tires so it was a bit of a risk going for the unproven Road 5 tires that paid off for me. I’m not at 10,000 miles on those and they’re just now down to the wear bars. That’s on my tire-shredding Kawasaki Ninja H2SX bear in mind. If I was planning on keeping the Ninja I would seriously consider testing these Dunlops but the review wouldn’t be ready until August or July 2021 so it doesn’t really help you.
