Four new tires

[mmcirvin]

That's one less thing to worry about.

The left front one was not only leaky but had developed a disturbing lump in the sidewall. They were all getting on in years, except for the one that had been changed a couple of years ago when its predecessor went flat, and that one had some foreign object sticking out of it near the tread that I just noticed today. They all had to go. It's better to have identical tires on the same axle anyway.
