"But aren't performance tires softer than touring tires?
The other day the guy at a local tire shop mention Toyo Proxes TPT when I say I want low rolling resistance tires for mileage sake. He also says Yokos are crap, Nokians are waaaay overpriced, and Hydroedge is better than Turanza LS-T, and my alloy rim choices at 14" are very limited without going at least +1. Told him I use 185/65R14 when I asked him all these."
The rubber compound of a performance tire is probably softer and stickier but the sidewalls are generally much stiffer to withstand high speeds and brisk cornering Associated with aggressive driving, etc.
It is quite an experience to observe and touch new tires in stores. Same brand and size, a standard touring S or T rated tire vs a high performance H or V rated one... I thus promptly eliminated the latter for my intended use.
On the other hand, all tire company's have older/lower priced tire lines that don't deserve interest. That doesn't mean that they don't sell high quality tires. To say that Yokos are crap is a bit simplistic in my view. Either the guy doesn't carry that brand or I might try another shop...
