I asked Dunlop a question about the RoadSmart 3, and received a thoughtful and detailed response. I thought others might benefit. The email I sent: "Hi, Are the Dunlop RoadSmart 3 tires, sizes F: 120/70x17 R: 180/55x17 suitable for a 2016 BMW R1200RS? The “Tires for my bike” tool on your website displays only the RoadSmart 2 and SportMax Q3 for this bike. Is the RS3 is a suitable replacement for the RS2? Are the RoadSmart 3 tires in the sizes above able to handle the load of the R1200RS fully loaded with passenger and luggage? The GVWR for the bike is 992 lbs. Other tire manufacturers seem to offer both “standard” and “heavy weight” or “GT” options on their sport touring tires. Most specify “standard” for the front tire of the R1200RS, and “GT” for the rear. I’m curious why Dunlop does not need to do this? Thanks,"Response from Dunlop: "Thank you for your interest in Dunlop Motorcycle Tires. Our RoadSmart 3 is a suitable fitment for your bike. The RoadSmart 3 is the [successor] of the RS2 and has the same load index for both front and rear tires. Our tool might just not be up to date. Each tire size is classified with a Speed/Load Index. The Speed index is determined by the tire manufacturer but the Load index is determined by the tire size. So for the Dunlop 120/70ZR17 the max load capacity is 520lbs @ 42psi and the 180/55ZR17 max load capacity is 805lbs@42psi. This is the same exact load carrying capacity as our competitors who mark their tires GT. In fact, between our competitors GT and non-GT tires, the load carrying capacity is also the same, so we don’t see any difference in actual load carrying capacity between their tires. The Dunlop is fully adequate for heavier bikes such as the BMW K1200GT and even the heavier K1600GT. All testing is done to DOT standards which is determined by the Speed/Load Index of the tire. In addition to this, the Dunlop is the only motorcycle tire designed specifically for US roads. So the benefit is that we actually use the roads you ride to develop the product so this makes it much easier for us to meet the true requirements of a sport tourer without compromising performance. We’re fairly confident that our competitors cannot say the same. Regards,"
