I've been off the bike for about a year because of an illness, and as I get back into it I'm tuning everything up. Today I replaced tires on two road bikes and, coincidentally, on my wife's Mazda.
Now, I'm an old guy, and I realize I can't get Contis for the bike for five bucks or Pirellis for the car for $35 anymore. What surprised me is that pretty good Schwalbes for the Atlantis--about 12 or 13 ounces of rubber, fabric and technology--cost $45 apiece and will last me maybe 1500 miles. Pretty good Bridgestones for the Mazda--30 POUNDS of rubber, fabric and even more impressive technology, rated to 130mph and sure to last 30,000 miles--cost only $25 more.
I'm not saying bike tires should go 30,000 miles. But I'm mystified why they cost as much as they do.
