chuck4788 Posted April 17, 2017 Report Share Posted April 17, 2017 I just purchased a new Dunlop D803GP tire (120/100R18) to replace a D803 (4.00R18). I expected a low profile tire but what I got seems to be a higher profile tire than the 4.00R18. It appears narrower and the loaded rolling circumference at 5psi is greater than the 4.00R18 at 10psi. The tire is made in Japan by Sumitomo Rubber Industries Ltd. So I'm now concerned that it may not have better traction. Anyone have some experience with this tire?

collyolly Posted April 17, 2017 Report Share Posted April 17, 2017 I thought all competition tires were made to a standard with regard to overall dimensions and tread pattern, why do you think there is a difference ? Quote Link to comment Share on other sites More sharing options...
pauls320 Posted April 17, 2017 Report Share Posted April 17, 2017 I have a set of GP's on one of my bikes to try'em out, the other has Michelin lites. I have come to the conclusion that, the GP seems to be working Great and I not being an expert rider by any means find no real noticeable difference...(Experiment with what air pressure works well for you though)..And the GP is almost half the cost of the Michelin which is a nice bonus. Enjoy them and keep your feet on the pegs Quote Link to comment Share on other sites More sharing options...
chewy Posted April 17, 2017 Report Share Posted April 17, 2017 Lets hope this becomes a very hot topic...some real competition for Michelin is long overdue.......is Dunlop still the preferred tyre for the SSDT (stays on rim better when punctures arrive). what we all want to know is how good is it.s grip and feel how easy to fit how long does it keep its edges how much is it 1 Quote Link to comment Share on other sites More sharing options...
beta_blocker Posted April 17, 2017 Report Share Posted April 17, 2017 Great tires. And Great Price compared to Michelins. Run 6psi ft. 4psi rear. I still contend in a blind side by side comparison 95% of people could never tell the difference. Quote Link to comment Share on other sites More sharing options...
carlos Posted April 17, 2017 Report Share Posted April 17, 2017 D803GP, Love em, lasts way longer than a Michelin. Michelin still works a little better on the real cold snowy day's. 1 Quote Link to comment Share on other sites More sharing options...
collyolly Posted April 17, 2017 Report Share Posted April 17, 2017 Where can you get a Dunlop for anywhere near half the price of a Michelin ? 1 Quote Link to comment Share on other sites More sharing options...

digger144 Posted April 17, 2017 Report Share Posted April 17, 2017 absolute rubbish tyre, I thought they were supposed to hold air, I have a brand new tyre fitted to a new sherco & you cannot run below 6psi, I have tried all the usual tricks . ended up fitting an X lite problem solved.other riders have had the same problem, how can they sell a tubeless tyre that does not hold air,I mean DUNLOP for goodness sake 1 Quote Link to comment Share on other sites More sharing options...
chuck4788 Posted April 17, 2017 Author Report Share Posted April 17, 2017 I'm using it on a dirt bike with the Tubliss system and it has held air for several days. The X11 on my Monty is still working good. The reason for the new D803GP is the D803 on my XR began leaking air thru the sidewalls from me running it too many miles at very low pressure. Based on the tire size I expected a low profile tire but ended up with one that is taller than a D803. Quote Link to comment Share on other sites More sharing options...
wheelieman14 Posted April 17, 2017 Report Share Posted April 17, 2017 (edited) Having tried Michelin X-Light, X11 Competition (came on '16 Beta Evo 300) and Dunlop D803GP, I've noticed even a worn X11 provides some pretty amazing grip, but doesn't seem to be available option to purchase in USA. I've also used a couple sets of D803GP and when the pressure is properly set for the conditions - feel the Dunlop is just as good as either Michelin model for significantly less money. I watched a video from RYPUSA putting aluminum tape (4 layers) on a Morad rim to get a better seal at the bead and help prevent slow leaks with tubeless rear trials tires. I use generous amounts of "tire slick" tire mounting lube and seem to get a better seal than new tires installed from the (Beta) Factory. having reversed direction of rear tire at 28 hours ride time.
