best dirt tire for 17 rear and 19 front

[imagex]

I have a Kawasaki 250 with 17 rear wheel and 19" front wheel.

I have 50/50 tires which are great but want something more serious for off-road / mud / rainy season.

I can't find for my sizes easily. I'm probably going to have to mix and match 2 different models - but even that is hard to find.

Anyone any recommendations for an off-road 17 rear (width 120 or 130) and an off-road 19 front (width 70 or 80)

Try to contact Piroj at Big Bendum in Bangkok - Phone 089 1115962 and see what he has or can get.

You could put a Continental TKC 80 on the back
