2010 RT Tire Replacement - do I need to use beads to balance it? What size valve stem?

[Lady HardlyRider]

Hi y'all! Been having so much fun on my 2010 it's time to change out my rear tire. I'm replacing with the same one I had before... The Kumho AST KU25 225/50R15 91H. Lol My bike/s mechanic and my husband are two different people. Bike mechanic does what I ask. Enough said.
Questions...
1. Do you guys suggest putting beads in the tire for balancing? Is there recommendations on which to use if so?
Probably TMI: Hubby doesn't like using beads, feels it makes my MP3 500 and RT tires wear in the center. I disagree, and my bikes mechanic does like beads lol. Hubby has a Honda & Harley. I drive the Spyder and usually keep peace by having my own shade tree mechanic for my bike repairs & biking desires rofl.

2. To replace the valve stem is the correct size .453 diameter rim hole? My mechanic has replaced all my tires in past but it's been several yrs since the rear was changed! I love my Spyder.
Meanwhile, I "HardlyRider" ->the MP3 anymore. It's always having issues lol!!
Thanks in advance for any suggestions!!!

Beads don't wear the tire in the center. Try running 18-20 lbs. in the rear tire and see how that goes. 3oz. of beads will do the trick. Be sure all the weights have been removed.

Glass beads work better than ceramic, in my opinion.

My personal experience is in 100% agreement with BaJaRon. I'm running beads in my Spyder, it rides smooth as silk. Your tire wear problem is more to do with air pressure. If the center is wearing, then you are running too much pressure. I run 18 pounds in all 3 tires.

I've been running beads in my cars and trucks for years and years. In fact, I much prefer them over wheel weights - especially in my dually!

I have been using beads for probably over 12-15 years now. Bikes cars,3/4 pickup. They work well. One advantage is they balance the tire thru its entire life.
