After doing research on the Brozz tire sizes 17/19 here is what I found. This is after researching this site, multi other forums, net, and talking with 3 major brand bike shops. Here is list of what tires are
available for the china bikes with the:
OEM front rim size 1.85x19, tire size 90/90/19
OEM rear rim size 2.5x17, tire size 110/90/17
Replacement Tire size:
Front 100/90/19 will work on the 1.85 rim for the front.
Rear 120/90/17 will work on the rear 2.5 rim.
I did a search of tire manufacturer sites and here is the model of tires they make in these sizes. I did only matching pairs since I do not run mix match tires. SO if you do there are a few more options that you could mix and match.
I did find one perfect match for the OEM tire size. But couldnt fine any state side but they were listed on Michelin USA site so you may be able to order them.
Michelin Sirac 110/90/17 and 90/90/19
Second best match and china rider favorite is
Shinko 244 2.75x19 front and 4.6x17 rear
The follow are tire brands that make the 100/90/19 front and 120/90/17 Rear.
AVON - Trail Rider
Mitas- Terra force, E07, E08, MC-24, E09 (Terra Force is new and caught my attetntion I will be looking for a review on these)
Metezeler- Tourance
Dunlop- Trail Smart
Continental- Trail attack 3, Trail attack 2, TKC 70, TKC 80, Escape
Perelli- MT60
Kenda- K761, K760
Now money wise and performance wise Shinko 244 is Top dog, and under a $100 a set. The others will be much heavier especially the AVONS they are like lead. They will also set you back most likely over $200+ a set.
Hope, this helps those looking for replacement tires.
Also here are couple links I found worth a read.
