tires for kz305

the original equipment on my wife's '87 kz305 was listed as;
dunlop
front 3.00s-18 4pr
rear 120/90-16 63s

I e-mailed Dunlop for best replacement but didn't get a reply.

I would really appreciate if anyone can tell me what they are using or any suggestions as to narrow my search.

Thanks
Jerry

Any help from this?

they list a 1982 kz305, I'll have to research if they are the same as a 1987
thanks
