I currently have the 5 stock 15x8 rims & tires on my trailer. I'm thinking about purchasing 5 Rev Shooter rims (BassCat Rims). I noticed that my stock rims have a hole in the center that allows me to currently pack the bearings with grease & the Shooter Rims don't.
I probably put about 7k- 10k miles a year towing. Is this a big deal? How often do you guys pack your bearings?
