Why...

Why are tire balls so expensive?
Do you get a discount for buying a set for all 4 tires?

Because the material and manufacturing process is extremely expensive. Call me and I can talk to you about a discount. 877-tirebal

Jeff, I was just wondering if its bad to run 14 tire balls in a rear tire? I see your saying 13 but is 14 bad?

[cdalejef]

Worst case is the tire will feel hard and they could possibly jump on top of each other.
This is assuming your talking about a 20" tire.
