How long do Ribs have to rest

Hello fellow brethren. I need ur quick advice. Im kinda a newbie at this. Today I went to Mi Pueblo and bought their BBQ ribs. Went home seasoned and threw those bad boys on the grill at 250-275F. Pulled them at 180F. Is that too high for ribs? How long do they have to rest? Im getting hungryray:

thanks for your opinions

Thanks.... Those ribs r already gone .... Couldn't wait any longer...meat pink and pulled right off the bone.... I guess the wrap and rest thing is only for large cuts of meat.
