WTF would make my tires wear like this????

Before you get onto the "YOU NEED NEW TIRES!!!!" thing...I already ordered some, just waiting for them to arrive.

Anyhow, why are they like that? They're scalloped, but particularly, it's worn smooth OFF CENTER.....

When you look at the overhead shot, you can see how they're scalloped and there's a block of tread actually protruding to a point off center, then the worn flat spot. When you run your hand over it, it doesn't feel smooth round all the way around like it's worn evenly, rather, it's flat, hump, flat hump, as if I had flatspots in the tire.

When I lean left during a turn, I feel it "fall" into the worn spot, but how the hell is that worn like that if I can feel myself fall into it? You would think if it were wearing off center like that, I'de have a cambered wheel....or is it truly crooked???

Is it a wheel balance issue? I looked, and I have no balancing weights on my front tire

The bike doesn't veer to the left, and it stops in a straight line, and oddly enough, there's no wierd vibration from it...wtf causes this, so I know how to prevent it on my arriving tires? And before you ask...that's just under 8K miles on that Pilot Sport....

My rear however, is wearing completely normal.

I've seen this on soft tires used for street riding. I believe it's a combination of road crown loading the tread left of center and the habit of pushing the front a bit when making a left turn from a stop. We turn left in a larger radius than on a right turn (from an intersection) and tend to get on the gas a little harder.

but why would it ALSO cup like that??? Not to also mention, it's not smooth, there's flatspots on those worn out places, like I sanded it down. It's funky...

check the suspension settings - specifically the compression damping (the adjuster on the bottom of the fork leg - at the axle). see if that one is out of wack.

btw, the brutale manual should have some suggested settings for general road riding. i'd start with those then tweak it as you like

Well, I just went out there and adjusted the suspension settings to the softest setting according to the manual. There was only soft standard and rigid.....it was previously on rigid...we'll see tomorrow on the ride to work, how I like riding a "plush" bike....

be sure there isn't anything on the bike rubbing the tires!

I have seen tires wear in very odd ways as a result of low tire pressure or a good panic stop where they actually wore a flat spot from locking the tire up, but I have never seen anything like that.

I think a good starting point would be to check your tyre pressure gauge accuracy, I am actually an Instrument technician by trade, and auto tyre pressure gauges are pretty poor on the accuracy front, it's not unusual to see 3 psi difference between them
You probably need to spend (in the UK) around the 15-20 to get a reasonable one, cheap digital one's are usually worse. Try and get one from the like of Demon Tweeks in the UK, or a Racers Hardware store in the USA, just to make the point, F1 type gauges cost wise are in the Hundreds of pounds

we'll see if the SUSPENSION changes help
but....
this is 100% a ROAD CROWN issue as was mentioned above
where I live... the roads have SUCH a high crown that the LEFT side of my tires ALWAYS wear out first.... please remember that there are FEW TWISTIES in florida

the UP side... we rarely IF ever get any standing water on our roads after the usual florida downpours
