Why would you even consider putting a car tire on a motorcycle?
Motorcycle tires are a pet peeve of mine. I have ridden a lot of miles, and so have a lot of experience with different makes and models of tires on a variety of different machines.

To point out my peeve with motorcycle tires, first I will discuss car tires just a moment:

25 years ago, a tire for my car cost $35 and lasted about 30,000 miles. Occasional failures of tread or bead/such were expected, but not frequent.

Today, a tire for my car costs $90 and lasts 70,000 miles. Failures are unacceptable and very unusual and are covered by extensive warranties. We've tripled the price and more than doubled the miles. In addition the technologies have made them handle better in cornering, wet-traction, braking, and heat-shed than ever before.

By contrast, 25 years ago, a tire for my motorcycle cost about $20 and I could expect it to last 8000-10,000 miles. Failures were common and there was no warranty coverage beyond the first install. The tire maker would provide instructions and materials on the safest and permanent way to repair a simple puncture.

Today, a tire for my motorcycle costs just over $200 and I can only expect it to last 8000-10,000 miles. The price is 10 times higher and I can expect no additional miles. Failures are frequent and there is no warranty coverage beyond that it will hold air when you first install it. The manufacturers will look you in the eye and inform you that there is no-way, no-how that a single puncture can be repaired-throw the tire away. Although there have been technology improvements in the super-gummy race-bike tires, the cruiser tires perform about the same as they did when I started riding.


How does it handle?

I am happy with it. It is very smooth and stable at high speeds, and for me at least, at very low speeds (full deflection turns for instance) it is an improvement over the motorcycle tire. Basically, I've found it to be superior in all conditions.

There are two areas of difference in feel:
It requires active counter-steering to put the bike in a corner.

t's flat! How can it turn?
Well, it's not really flat. This tire has a profile; it is just not as radical as the motorcycle tire. Remember that it is the back tire's job to stabilize the bike, in turning it is the front tire's job to de-stabilize the machine so it can lean into the turn. With the different profile, this back tire is just trying a bit harder to stabilize me. It does not reduce my turning response or authority. My line and speed into hard corners is unchanged, and I have the added benefit that I can absolutely slam the throttle exiting the curve without so much a squiggle. The Valkyrie on the stock tires or the Avon rear would spin it out from under you, resulting in all sorts of unpleasentness. One more advantage is that "flip-over"...that is, coming out of a hard turn in one direction to a hard turn in another direction is substantially easier and faster than on a standard tire.

ITS BEEN DONE, AND IVE SEEN IT IN PERSON AT A CAR SHOW. AND IT LOOKS LIKE ***....

AND MY CAPS LOCK IS STUCK ON SINCE IM IN A DIFFERENT OFFICE AT WORK...

WHAT I ALSO DONT UNDERSTAND IS WHY PPL WANT TO PUT A 300 TIRE ON THE BACK OF A SPORT BIKE
