Check your Air Pressure, I run "Max" in all my tires. the stiffer sidewall works better and you "feel" the road surface better for more control.

My ct experiment is over. With a little over 3k miles and a long ride yesterday on some real twisties, I'm a convert. I'll never put a mc tire on the back of this bike again.

Hearsay with me, but I do think that you are not running enough tire pressure. Add more in increments of 5 psi. And/or your rear air shock might be too soft.

If it is squirrelly, to me that says the sidewall is too soft.
There are way too many Austone taxi tires running on 1500s with excellent reports for it to "just be the tire".

I did some looking for you, read these.

There have also been reports of what the OP is experiencing, that didn't go away...... Is not Pressure related, balance related, bearing related........ Not sure what it is.

I know I have experienced it on my 1500 and will be ripping it off the bike before it leaves the garage this spring. It seems the more it wears, the more dangerous it's handling ability is getting. Not every one has experienced this "squirrellyness" But for those of us that have experienced it, don't like it and either have taken it off or will be taking it off............ There is no fix to it that any of us have found.

Ran the tire pressure up to 45 psi, rear shocks up to 50 psi and had the same squirrelly ness. Ran the front shocks up to 8.5 psi from 3 psi and it made a huge difference. Still not as solid as before, but much better. That make sense?

How long since you rebuilt the forks? Greased and torqued the steering bearings?

Welcome Jeddy460:
I installed
my Austone 2.5 years ago, love it! Its current mileage is 22K and tons of tread left. I get that squirrel'ly feeling in turns too BUT I've learned to understand it, I now expect it and ride with it.

My take on what's happening.
In straights 2 tires of relatively the same size and track inline are working together. Bike tires in turns are still slightly out of line and the rear is tracking a slightly smaller radius. While turning they're not entirely working together, they're slightly fighting each other to go in two different, forward directions.

Now put a wider and flatter (car tire) on the rear. In straights the 2 tires are basically working together, although the CT being wider has 2 outside edges wanting alternating grip. Some folks call the rear tire seems to always hunting to go straight. Extra air pressure helps until the treads center is flat again.

I can go into deeper detail but the original poster didn't ask for that.

That "squirrelly" feeling you're getting, in a nutshell.
Compare it to 2 front car tires that are out of alignment and making a turn. Each tire is hunting its own path making the car jostle around, sometimes a lot.

It can dangerous if you fight it, so loosen your grip and "Let the Wing do it's thing".

I hope this short explanation makes sense.


Additionally, I pull a large heavy trailer. That Austone is fab! LOTS of extra footprint grip.
I've hit 'black ice' before in my past on MC tires, the bike went down FAST. Last year, rid
ing about 50mph I hit 'black ice' in a slight turn and the bike lost grip. Not getting excited, I immediately but slightly rolled off the throttle keeping the rear wheel turning. A mistake remembered from experience. Anyway, that wide Austone grabbed the ice more than the front and straightened out the bike.
I'm now more hooked on CT's on the rear.
