Help me with tire sizing for my wife's DR200

My wife bought an '07 DR200 which has the original tires. (!) There are a set of Shinko 705 (dual sport) tires that seem perfect but when I use the original sizes (knobbies) I can't find many tires. Will the Shinkos work?

Stock are:
Front - 70/100-21 44P
Rear - 100/90-18 56P

And the Shinkos I have seen recommended are:
Front - 90/90-21 (H speed rated)
Rear - 4.10-18 TT (P speed rated)

I know that the numbers are width/aspect and diameter. But will they fit? And is 4.10 listed in inches? That would work out to 104cm so pretty close, but what is the aspect? Ugh, I love standards...


Thanks,

I'd go with the 244 series - 2.75-21 and 3.50-18.

She wanted more 'on road' tires. You recommend the 244 for better fitment or to better keep in the original style?

I tried to show her Super Moto bikes when she was shopping but she loves the 'dirt bike' style, however she's not really caring for the on road feel of knobbies. I'm just happy that she is riding!

For size - stock rims are pretty skinny and you have to watch for clearance especially on the rear.
