A businessperson with integrity. He knows the tires are poor so he won't sell them. They do still exist.
More than likely your guy was selling fear to up sell you.
I have Kumho ASX's on my SC400 now for 20K miles. Guess what they are very good tires. Except in snow over ~3 inches.
I'm rather particular about tires. But after years in sales and marketing I understand a few points about human preception and price points.
I've driven 80's vintage bikes over 120 mph, cars +170mph and aircraft supersonic, I understand the varibles of perfomance.
Had topline Michelins and Brigestones and Goodyears on the car before. Nothing SIGNIFICANT in the cars performance between each brand except for the lack of flats relative to the $250 Michelins and Goodyears wearing out quickly (~20K). So I cheaped out this time. I'm VERY happy I did. These tires can't be beat for the price. Everyone is discussing shades of grey in performance. What about real life significant improvements. Most people can't notice a quantitative difference of anything greater than 10-15% change. Most people compare the feel of tires to the prior worn out set. Most people are conditioned that higher price must mean its always better. These tires deliver what they promise. If you need to pay and additional $170 per tire for a 5% increase performance that you'll likely never notice, more power to the tire companies marketing teams.
