Piston Slap: Spare Me Your Noisy Rubber!

TTAC Commentator gtemnykh writes:

About 5,000 miles ago, I installed new General Altimax RT43 tires on my 2012 Honda Civic LX, a well-regarded tire according to most sources. Everything was great when I first had them installed: No noticeable increase in noise and much better wet grip.

It was only several thousand miles later that I noticed tire noise. It’s loudest between 40 and 50 mph and sounds like I’m riding around on snow tires. At highway speeds, it’s less noticeable or not at all.

My question: Have you heard of tires starting out more or less quiet, only to later get louder as they approach 5,000 miles?

Cadillac Reports 43% Of Dealers Will Not Sell ELR

A niche vehicle is one that serves a very specific set of buyers with a vehicle that’s defined by a specialized and uncommon or unique role; and is often knowingly sold in low numbers to satisfy that dedicated group. Sometimes it’s to test a market: The Miata created its own niche in the 1990’s, and became a role model for modern product, like the S2000 and BRZ/FRS. Other are more esoteric niches, like the Nissan Murano CrossCabriolet. Sometimes, niche cars bring buyers to a brand that they would not have thought about before.

Currently, one of our most popular niches is the hybrid segment, dominated by the Toyota Prius. Chevrolet threw their hat into the ring, inadvertently, with the Volt. Though primarily an electric car, it does run the gas engine as a series hybrid with engine lockup if needed for maximum efficiency. The sales have been mediocre, pushing just over 23,000 units in 2013. The Prius? It sold over 145,000 units in the same time period..

Is it any wonder, then, why 43% of Cadillac’s dealers aren’t willing to take the up-market, $75,000 (before $7,500 Federal tax credit) Cadillac ELR? It’s a niche of a niche. And it’s an expensive one for dealers to take a risk on.

  • Mister It wasn't helped any by the horrible fuel economy for what it was... something like 22mpg city, iirc.
  • Lorenzo I shop for all-season tires that have good wet and dry pavement grip and use them year-round. Nothing works on black ice, and I stopped driving in snow long ago - I'll wait until the streets and highways are plowed, when all-seasons are good enough. After all, I don't live in Canada or deep in the snow zone.
  • FormerFF I’m in Atlanta. The summers go on in April and come off in October. I have a Cayman that stays on summer tires year round and gets driven on winter days when the temperature gets above 45 F and it’s dry, which is usually at least once a week.
  • Kwik_Shift_Pro4X I've never driven anything that would justify having summer tires.
