would these fit (not about bearings..)
 

do you think mini-z/x tires would fit these..they have alot better looking compounds out for them and im thinking about buying some..

Standard mini-z and mini-x tires are not as wide as standard XMODS tires (about 1/8"difference). They also have a slightly smaller inside diameter that XMODS tires so they are harder to put on but will fit . I believe there are wider than stock mini-z tires available. I do not have any but I am sure that they probably exist.
