I am looking to replace my stock Dunlop Elite 3 front tire and D417 rear tire on my 2008 Vegas Low. I am leaning hard toward the Dunlop ( Harley ) D407 & D408 combination because of the multi tread compound. Have called Dunlop just got a recording with no call back yet. My question is: Harley designates the front tire as an MH 90/ 21. Is that tire a 90/90/21 which is the stock tire size for the Vegas or is it an 80/90/21? If it is an 80/90/21 will that cause a problem. I have been hearing about Dunlop making MT tires for Victory bikes but the only ones I can find for my Vegas are the Harley brand. Thanks for your help!
