E3 Rear Tire being replaced

Ok, took these pics of the E3 2nd gen rear tire with about 16000 miles.

Will be replacing with another E3.

Looks like one spot on the tire was getting kind of bald.

But over all I am happy with the mileage.

Thats real good mileage for the rear tire. I thought i was going to the E3's but I found another E2 and put on the rear this week. I lost the mileage when I put it on, so I don't know how many was on this one...

I'm sticking with Dunlop tires.

That one MIGHT have made 20k but that last pic looks kind of doubtfull!!

Sure looks like it's cupped pretty bad though.. don't often see rear tires like that...

That last photo is pretty funny!

It looks to me the rear may have another 1000 to 2000 miles, if you really want to push it to the limit. The crack on the middle part of the tire is what concerns me the most. +1 on the cupping...not common on rear tires.

I'm not sure about the crack in the rear, all we really got to see was pretty well worn and maybe ready for some 'retreading'.

Check the 3rd picture. You will see a crack on the middle.

I already have the new E3 here. I wanted to see if I could break the mileage I was getting on the Avon (between 13000 and 14000). The crack is why I am swapping out now.

Not sure why the cupping though, check pressure regiously, always between 40 and 41 lbs. max is 40. And 99% of the time, 2 up.

George, I usually ride with my rear Avon at 45 lbs riding solo, and I have been getting great mileage out of them, my Venture still has the first Avons on them with about 7-8000 miles on them and still have plenty of tread and no signs of cupping, when riding double I up the pressure to 50...........running a higher pressure makes the ride a little harder but its better for the tire, doesn't let it cup. If I were you I would think about running a little more air in the rear since you are 2 up all the time and usually pretty well loaded down with camera and memory cards.............LOL,

And by the way the pic of that bald spot in pic 4, looks like a retread is in order............

OK, let me throw you another curve here, how sure are you of your tire gauge being correct? I ask this because I have seen several of the gauges 10% off or more. If you are off that much and running 40psi on the gauge, you may be closer to 35psi and that will definately cause cupping and reduced tread life.

This would be a good maintenance day or M&E project for someone to bring a tire gauge that has been calibrated and do comparisons with other gauges.

judging from the fact that most of your tire wear is down the middle i would have to say your tire preasure is too high.

The tire gauge is RideGear Electronic.

Also, not many curvy roads in SC, so most of my wear will be right down the middle.

I am thinking about getting a gauge type that you screw down and don't lose the air pressure on.

Its been my experience you loose more air with a srew on type because from the time it starts to open the valve core to the time when you get it screwwd on far enough to seal and then again taking it off you can loose a lot of air unless you have super fast fingers.

I just put a new WWW 404 on the front. The rear was new 1200 miles ago. From the positive experience with tires on my cages, I elected to put Nitrogen in the new bike tires. The Nitrogen seems to be immune to pressure changes due to temperature. And so they tell me the Nitrogen does not seep through the rubber as much as air. The 404s call for max pressure of 41psi, so I had them inflate them both to 40psi.

Just my thoughts on keeping pressure stable.
