hey guys im looking to get tires for my baby, im looking at sock size. i was looking at the Sumitomo HTR Z II. is anyone using these tire and can recomend them?

I don't know anyone that has those.

Bubba Foot is on his second set and loves them. Especially where Bubba Buzz lives (no cold weather) they would be perfect. A japanese racing tire with very aggressive tread pattern and outstanding ratings in every category.
Good in the rain and corner excellent traction and they wear better and ride smoother than anything I have owned seen or heard of. Make sure on any tire that you ask what the date code is and insist on the newest set they have.
You will love 'em and the price is right too For this review I charge an excellent cuban cigar, please..I know you got em there in Miami
