I just got the scorchers and mounted them on my Swift. Here are a few preliminary impressions:
1.) The tires are easy to mount. Almost too easy. No tools required! Which kind of worries me, particularly the fear of the bead blowing off the rim. In contrast, the Comets are tough to put on and take off and require a tire lever. The Scorchers can easily be installed by hand.
2.) The sidewalls feel really thin and flexy, which almost fooled me into thinking they were kevlar beaded. It's probably why the tires are so easy to install.
3.) There's an overall feel of less material in the tire than I would expect out of a 20 x 1.50. The weight difference between the 20x1.35 Comets and 20x1.50 Scorchers (55gm) is almost undetectable when hefting the two tires. These tires are light for their size.
The Scorchers remind me of the Michelin 700C racing slicks way back when. Slick, supple, and sticky.
I'll give a first-ride report tomorrow.
