i bought my new tire. 225/45/16. they are maxxis stg...i bought what they had in this size. I alos, bought 5 mm spacer that were 4$ each(i thought spacer were more like 50$ for two). They are not hub centric tho.
You don't want those. Will tear apart your hubs, wheel bearings, tie rod ends, ect... That and the vibrations while you drive from your wheel being out of balance will probly drive you nuts; not to mention eat up your tires irregularly.
You can find plenty of cheap hubcentric 5mm spacers on ebay.
