Ok so I have noticed hear this summer that my front tire is wearing really funny. It is wearing to a crown. We have checked the wheel bearings and there is no sign of bad bearings. This was my first thought is great I have bad wheel bearings.

So ok I have a 08 vision
7500 miles on it stock tires.
Any help or has anyone else had the same problem. I have never had this problem with any of my other bikes.
Thanks and God Bless

either a tire pressure issue or wheel balance issue.
both can cause uneven tire wear.

Im thinking its a wheel balance issue but not sure cause of the crowning. Tire pressue is right on the money 26-29 psi.
So Im puzzled a bit.
Forgive my ignorance; I know the crown of the tire is the center section but is crowning when the tire is wearing the center more or is it wearing the outside more?

I would expect you are wearing the ouside more since you are running your tire pressure around 10 psi below what the 2009 manual call for (the 2008 manual isn't available on-line).

Page 191 states
Front 130/70R18 63H Dunlop Elite 3 36 psi (248 kPa) 38 psi (262 kPa)
Rear 180/60R16 M/C 80H Dunlop Elite 3 38 psi (262 kPa) 40 psi (276 kPa)

From HOW TO READ TIRE WEAR

Under Inflation
This type of wear usually results from consistent under inflation. When a tire is under inflated, there is too much contact with the road by the outer treads, which wear prematurely. Tire pressure should be checked with a reliable pressure gauge. When this type of wear occurs, and the tire pressure is known to be consistently correct, a bent or worn steering component or the need for wheel alignment could be indicated. Bent steering or idler arms cause incorrect toe-in and abnormal handling characteristics on turns.

The Dunlops do this, it is a characteristic of the way the tire is manufactured, not sure but I believe the compound is harder in the center. I have had a couple of sets and both did this on the vision and I am seeing the same on the cross. This is only one of the many reasons my vision has Bridgestones on it.

If your Dunlops are cupping, that is a tire pressure, balance and shock pressure issue.

I had similar issues on my venture with the Dunlop 404 but I just put some Elite 3 on front and back and they are a world different than the 404. I know the bridgstones that are for my bike don't last and get out of round from what I have been told. I know some use the michalin comanders and have good luck also.

I'm having this same problem

I think that I am having the same problem with my 2011 XC. The Elite 3's that I am running (Stock) have a ridge on the front (I noticed it on the ride home from a trip when I started feeling the road snakes) and hoped that I would make it home.

The tire seems solid, but it is as if there is a bump in the middle. There is also a bit of it on the back tire (and this is only after about 11K or 6000 miles). I am used to having to replace two back tires to one front, and this is a different experience for me.

I checked the pressure (cold) and it was 38. At the end of the day, I checked it hot and it did make its way to 42, but that is normal, is it not.

This "is normal for that tire"... doesn't make it right, but it "is normal" LMAO

IMO Dunlop makes shoddy minimum spec tires for bike manufacturers with numerous quality control issues... this is one of them. the "crown" is because Dunlop in their infinite wisdom decided to "beef up" the E3 and in order to do so added a thick belt of rubber under the crown section. Little did they expect big bike riders to ride on the sides as well... Hey Dunlop, we do!!! The difference in thickness of the tread area of the tire was so that Dunlop could rate the tire at a higher weight thus making it seem to be a better tire for the heavy Vision Tour and Cross Country/Roads. They must not be the smartest or they are very smart in putting this design out there... they have Polaris fooled, but I am not sure that it takes too much to do that.

Inherently, with this design the heat build up and resulting tire wear is out of kilter. The sidewalls are wearing at an accelerated pace while the bulge continues to grow. In my opinion this is an inferior tire, and causes an increased failure to perform properly as a motorcycle tire.

I complained at 4400 miles on my Tour bike, and Dunlop replaced the tire... but get this... Polaris turned down the warranty and I had to pay to have it installed. GO POLARIS!!!

E3 Tire wear

Same issues for me. I just had my bike gone over by the dealer, it's at 10000 KM (6600 MI) of which I've done about 4000 KM since I bought it a month ago, mostly highway riding. I'd bumped up pressure to about 38F/40R when I got it,but they were a bit lower 32/37 when I'd first checked.
Dealer's service guy noted a new set of tires are needed when I'd picked the bike up today. Otherwise all was well. My front does seem a bit "pointed" in the center, not sure if this is what is meant by "crowned" or not.
How long is to be expected IF tire pressures are kept up properly from new, and what other tires are recommended as better alternatives
I'm not yet that agressive, so wouldn't have expected the center of the tire to be "outlasting' the sides due to heavy cornering etc.
