looking at my oem tires it is a Dunlop K591 160/70R17 on rear and a D401F on the fron 100/90-19. So is that a radial on the rear and nonradial on the front. Can I get the Metzeler ME 880 Marathons? They are bias ply and it says tubeless. I have laces wheels and they say I need a tube, can you put tubes in if it says tubeless? So many question but I am so unsure of what to do. I do mostly back roads riding, not much highway and I am more of a fair weather girl. But I also race motocross and ride endures so I do like to rip around fast through the turns, etc. Thanks for any help anyone can give me

it usually says on the tire, Tubeless but if needed fit a tube.
