You're forgetting your math. Higher tail on a bike means steeper steering angle, and quicker turn in.Hard to believe that it would be anything but bad. Car tires are not designed to run on the edges. The COG of the bike is also going to be a couple inches higher than normal when leaning into a corner over due to the square cross section - even worse. A wider tread will make the bike even higher during the lean.
Yes, the CT is designed to handle more weight. But also designed to work for a wide range of weights. 1/4 of a 2300 lb sports car to 1/4 of some big grand touring car, for example. We run pressures developed from our testing that work for the load we have. Mostly 30-32 psi. Contact patch is much larger than a moto tire in most cases. The problem with your imagination is it lacks experience. What really happens is that it's almost impossible for a CT to hydroplane on a bike. It throws a HUGE amount of water spray off the back! There are so many more tread blocks and sipes than on a moto tire that riding in the wet is simply incredible. Now, most of us run high performance all-season tires. You could conceivably run a summer performance tire that has no sipes and a compound that gets hard quickly in cool wet conditions and have issues. I've certainly felt that in a car! From great dry traction to horrible understeer in the wet on some nasty Dunlops.Also keep in ming that car tires are designed to carry a lot more weight than a motorcycle - probably no flex at all which will make the contact patch with the road very small. I would also imagine that if you hit a puddle you going to hydroplane like crazy.
Yes, it looks wrong. But it does in fact work quite well. At 28k on my BT 019 Grid, I'm not to the wear bars yet and probably have another 10k left on this tire.This looks like an accident waiting to happen.
Once again, it's really not that different, handling wise, than a moto tire.
More turn in pressure is required. (quickly gotten used to and forgotten)
It feels different in longitudinal seams and grooves because you're feeling each edge go on and off the groove/seam.
It tends to track more in car tire width grooves, so extra attention is needed in that situation.
Some of this can be aggravated by a worn front tire, and thus alleviated by a fresh front tire, as has been noted by riders here.
Most riders tend to develop minor riding traits to compensate for the oddities of the CT. Using more body motion when initiating turns, paying more attention to ruts in the road and staying out of them, being more aware of lane position, etc. None of these detract from safe riding, and in fact tend to increase rider awareness, which is a good thing, regardless of what tire you choose to run.
At this point in time I don't even notice the CT. I suspect it's gotten a little easier and more moto like as it's worn in, but I'm simply very used to it now too. After all, the CT remains consistent in feel throughout it's life. Unlike a moto tire that starts out awesome and begins going down hill right away until it's handling sucks by the time you wear it out.
