[urq] Slow Tire Leak

[Max Hoepli]

Hello all,

 

Unique problem. Have slow leaking tire, all tires have 5600 km, 9 hole
Al-alloy rims are at least 10 years old from S-Audi, not original to my car.
Was told Al-alloy when getting old will have problem of slow leak due to
oxidizing at inside inner rim. Anyone have such experience? In the tire shop
garage noticed workers will take large buffing machines and clean away this
gray like sediment from inner rims. Piles of gray produced in garage.
