Ahhhh, but I've seen him RIDE!! Gary dump the tire after 10,000 miles and put fresh rubber no matter what the tread looks like, it's done!. (The side wall can't take much more).
When I had an Alfa years ago I had a shop that would 'True'the tires, with a high speed cutter removing a layer of rubber from the tire while it is spun at near 100 mph rotational speed, (or some such BS) All I know is it made a racket and I didn't want to stand too near. Initially I was VERY skeptical about cutting rubber off a brand new tire, but when this was done I got more mileage and initially they were the smoothest ride I have ever experienced. You could feel a dime if you ran over it, the "feed back" was that great. before it is cut the tire 'bounces off the slightly high spots and comes down harder in the low spot wearing them faster and making the cupping worse and worse.
If you ride like the G-man, buy new tires, lots of them!! :lol: :lol:

The sticker on the down tube of my frame says, 34 front, 42 rear.

Manual says the same.

I've been running 40lbs up front and 42lbs rear since new. In 9000 miles haven't had any tire related problems, but after reading this, I'm starting to second guess myself.

I bought mine with 11,000 miles (UK) on it in Feb. Handled a bit iffy on the 200 mile ride home. Checked pressures next day and Rear was 38 front 30! No bloody wonder.
Put in 34 / 40 F / R was OK but ended up settling on 36 / 40 as best.
I have noticed the you can scrub the rear up to the edge but there's always a "chicken strip" left on both edges of the front. May indicate too low a pressure in the front?
I'm concerned that if I increase pressure in the front to 40 it will decrease the contact patch, although having it scallop does that anyway. I've never had the front end wash out or lock up. Have any of those running 40 / 42 had any problems?
I've had a Hardly in the past so may not realize that these things aren't meant to be as vague at the front as it has been. I have Progressive 440s on the rear and OEM on the front.

Sorry Jethro, just reread yours.
From other posts I'm guessing you ride it like you stole it, if that's the case, and you haven't had any problems with 40 I'll try it next time I'm out.

...I have noticed the you can scrub the rear up to the edge but there's always a "chicken strip" left on both edges of the front. May indicate too low a pressure in the front?...

The front tire will always have wider chicken strips than the rear unless you are running full lean (way past peg scaping point on stock Rockets) on a race track. It has to do with the fact that countersteering forces apply much more directional change than simply leaning your bike, so not all the tread is needed to corner the bike effectively. Also has to do with the front tire's profile, as the Rocket's is steeper at the middle to make cornering swifter and easier so this also means you will less likely need any front tire tread out at the sides. Another thing to affect your chicken strip is steering geometry. Decreasing your rake by lowering your front end will concentrate more of your contact patch to the center of the tire during cornering. Factor all that in and I'm doubting that you can eliminate front tire strips on a stock Rocket at sane speeds.

I certainly haven't been able to get rid of my front chicken strips on the Rocket in all the street riding I've done. Maybe someone who does track days on the Rocket could claim this.

I've noticed that scalloped wear pattern on mine at only 6000 miles.

Been runnin the stock psi.

G- I always ran 42 front and rear. front tire lasted 11K on both bikes. I actually wore the sides out before the center of the tread. NO Scalloping. I believe the tire manufacturers. Afterall, it's their product.

I cant beleive you get that mileage we must have roads like cheese graters my tyres worn badly(knackerd)the side we hit round abouts (rotarys) its only done 5500 i recon it was one of Rossis duff tyres.
