Nope rider weight and usage were much the same, if anything the Michelin has been worked harder.

Impressive difference. I'd go with city grips as replacements based on that comparison. Tread design alone would seem like they would grip much better and give a lot more confidence in cornering. Thanks gn2!

there is no difference in how different tyres work, i have had irc, Michelin and Pirelli, never road the scooter any different in all conditions, i think sometimes its in the mind or what you are used to. im a Pirelli man and that is what I buy now. :-)

Nope.
A few bends but no corners.

I would declare that at least for me the new tire/tyre feel was not just in my head. I bought a used PCX and switched my tires/tyres out within the first 200 miles. I had never ridden a motorcycle before so I was a complete rookie. Maybe because I was a rookie, or maybe because I'm not that bright ;) but the thought of a different feel to the ride never crossed my mind .... at least not until I came to the first turn (if you feel the need to respond to that comment, please don't ;) ). Immediately upon entering the turn I was shocked by the different 'feel', even to the point where for a split second I thought I was going to get thrown from the bike.

Excuse the possible stupid question but what exactly are the wear indicators? I've been keeping an eye on my tyres and they still look good.. But I've recently hit 10,000 miles which seems massively over what others are saying they replace them after.... Still handles as good as it ever did and I was happy with the grip in the recent rain..

Ignore that.. Just had another look, front still seems pretty good but back needs replacing.. Think ill put it in for a service and do the lot in one go..

The indicators are the little horizontal bars across the grooves.
When the tread gets level with them its new tyre time.

I changed my original rear tire at 5700 miles. I also now have a City Grip.

I'm about .1 mm away from the wear bars on my rear tire. I have 9100 miles on it. I'm going to get at least 10,000 miles from the stock OEM tires. I will be getting the city grips for both front a rear replacements.

Interesting how riding style, road conditions and braking preferences change dramatically tire life. Especially the rear.

6,000 miles and my rear IRC tire is really square. The front is still good. I ordered a Michelin City Grip for $62 shipped. I hope it lasts longer. I got 16,000 miles out of the IRC that came on the rear of my CBR250R which looks like the same tire. The front is still good and should make it to 25,000?

Well, I think I know why my fuel economy kept drifting up as I passed 6,000 miles on my way to 7,800. Apparently a bald tire rolls easier than a newer one.The new rear tire is not as fuel efficient as the worn out one was. Interestingly, the difference in circumference is only about .4 percent It looks to be a lot more. But the loss of fuel economy sems to be about 3% on the first few tanks. I was able to grab the wheel with the automotive tire machine at work so was able to change it myself and save the $50 that the dealer charges. My dealer doesn't have the fixtures to balance rear scooter tires so I also have Dynabeads in both tires and they work well to balance the tires for a smoother ride. I don't notice much difference in the cornering or traction but I hope the Michelin City Grip will last me twice as long the way others have reported.
