Wheel Spacers & Offset Wheels

Hey guys, I literally just bought my Rhino back in November and have only taken it out 2 since then.* I noticed that on my last ride that there are wheel spacers on all four tires. **I have ITP beadlock rims with the offset of 2” inner; 5” outer (I don’t know if that’s 2/5 or 5/2).* I believe they are 2” spacers all the way around.* I love the wide stance, but I’m afraid that I’m going to burn up the wheel bearings in all four tires.* What the biggest spacer I can stick on my Rhino with those rims that wouldn’t burn up the wheel bearings?* Basically I’m buying time before I end up getting a mid-travel suspension on her.* Right now dropping $2-3K on a mid-travel is just out of the question.

Also, would re-packing the bearing every few months increase the longevity of the bearings or would I just be wasting my time?

Thanks!
