I was slowly losing air from my front right tire and went to see if I could have it plugged.
Diagnosis - cracked rim.
I generally have driven on good roads, little or no potholes - and don't recall ever hitting a curb or significant pothole - and definitely not in the last week or so.
Anyone else ever have a cracked rim (base wheel)?
Now I am into it for a new rim and two new tires ($855)
Never had a cracked rim in over 40 years, and over 1/2 million miles.
First issue to speak of with my Model 3 after ~28,000 miles, could be worse ….
