replacing tires back on bike? lil help
 

been a while since i posted on here but once again i need help, haven ridding the bike in over 8 months due to an accident but recently wanted to start using it as a daily. so i was able too look up how to take the tires off but when i went to get the tires changed they gave me some spacers I'm pretty sure i figured out the front one but not 100 percent the rear ones are the ones that concern me because there both different also the torque for the bolts would be also helpful again tks as always guys and gals
