Still on the fence about going to the darkside!! At least for the moment I know I should get another 4K miles before I need to change the rear.. Not sure what to try next (will probably stick with the Avon's unless I have an issue in the next 4000 miles!!).

I will admit that I am very anal about air pressure in my tires. I know that Honda has their recommended air pressure and each tire company has their recommended pressure, I find that for the way I ride and the load I carry 40psi front and 42psi rear work with Cobra's on the wing for me. I also run Avon tires on my sport-touring bike. With the model tire and the load I run, I find that 38psi front and 40psi rear work for me on that bike. It may take a few sets of tires and air pressure adjustments to find a good combination. For me, Avon tire works pretty damn good. I would love to get more mileage out of the rear tire, but I'll give up mileage for all the other facets of tire cost. I have had mild cupping with both bikes on the rear with Avon tires. Much more with other brands. I put Dunlop E3 bias on my sport-tour and while the mileage was great, I hated the way they felt.
Bottom line. It is all about how you ride. I change my own tires, so cost is a little less for me. I ride a little aggressive (or more), so I need a tire that grips. I live in Illinois so I need a tire that has good mileage in the center of the tire. I ride two different bikes, sometimes solo and sometimes two up. I never ride across town just to say I went for a ride. I still think that finding a tire that feels good and gives you decent mileage is a personal thing. Finding the sweet spot in tire pressure and the style of riding is the harder part. Don't be PO'ed because you are to lazy to test and maintain an air pressure that works for you, the bike and the tire.

From reading through this thread, and others it seems to me the problem might have been the earlier Cobras that had the lower load rating. New ones have a much higher load rating.

Hi Rabbott, I do not check my tyre pressures very often :oops: , but I raced motorcycles professionally for a few years and am not easy on my tyres (I like to deck things out) so milage is important, but a long way behind feel/confidence. I am very happy with the feel that I get from my Avons, the wing is a fat old girl, so grippy tyres that give good feedback is something I value highly on this bike. I will probably change for another set of Cobra's with the higher weight rating.. I also change all my own tyres and as I only ride 5K miles a year, I am not too concerned if a tyre does 10K or 15K miles before worn out as that means I change them once every 2 or 3 years!! My dirt bikes go through several tyres every year!!

As per my earlier post. I rarely have an issue with cupping. The only time I had a problem with cupping was on my sport-tour when I bought it. Tires had about 5k on them, the rear was cupped to the point it needed replaced and the front was almost as bad. The pressure was 15-20% below both tire and motorcycle spec. While proper pressure may not improve mileage a lot, it will usually stop cupping. While I would love to get 15k before a tire change, I know that with my riding style, bike weight and road conditions 10k is average. I'm getting very good results with the Cobra front. Probably 15k+. I picked up a nail on the rear and plugged it around 7k. Due to the harder compound of the plug it started to cup around the plugged portion of the tire. So again, I'm over 10k on the front and just replaced the rear.
Since I mount my own tires, I would much rather get 10k with a tire that has good feedback than 20k of mileage. I tried that once and on cold days or in the rain I had serious pucker factor. If you are riding coast to coast or just mostly interstate more power to ya. Just saying, not for me. Watch the pressure and you will be happier with whatever you run.

I'm running an Avon tire on the front of my 2004 Wing. I purchased it because reportedly they were the only manufacturer with a true front tire? My Wing has the CSC kit and of course I run regular car tires on the rear. I purchased the bike with 26 K on it, the front tire needed replacing so I don't have any experience with any other tire. I have about 10 K on it now and not a lot of wear. Handles good with no problems during this period.

I have a 1300 VTX that I run Michelin Commander II's on. Absolutely love them. Best mileage I've ever gotten on a bike tire. However they cost a little more on the front end so that needs to be factored inl

well, here's my 2 cents. have a set of cobras front and rear with 16k miles on them. up till now loved them. great handling and STILL 42+ mpg. but, last weekend with a goldwing ride i noticed a strange handling problem when cornering to the right. VERY squirely. got home and did an inspection and was horrified to find several large lumps on the right side tread of the tire. i've heard of tread seperation issues and i think i just experienced it. anyway i've got a dunlop e-4 going on the rear in the morning. i guess i have to say i'm satisfied with the avon.
:lol: I know people say we spend too much money on our rides, but I can't hear them when I'm 1000 miles away! :roll:

Wow, that's the first I've heard of a failure like this on an Avon. I guess it can happen to any tire. Basically, when the belts inside either break or separate (manufacturing defect or impact damage) the rubber no longer has the tensile strength of the belts to prevent it from stretching, and so it bulges out from the air pressure, like a balloon.

I think you did well ...
They have a 15,000 mile warranty from the manufacturer when installed by a registered dealer-
I have about 12,500 on mine already and they are not worn out -- but they are getting noisy and are cupped -
I use Centramatic balancers on mine from day one and keep tire pressures checked often -
The rear has leaked down a bit over time but that may be due to the rear tire is a powder coated rim ..?
The front is still fine - but scalloped - and noisy when riding straight up - but quiet on the turns -
I will add another 2-3K on these and off they go --
I already have a set of Bridgestones mounted front & rear in the garage with 4K on them -
I like the G704/709 combo the best but 10,000 miles is all I get on them...so I change tires more often

I would have gone with another Cobra, but my local dealer was the only one with a tire in stock plus it was on sale for$210! Saved my weekend !

Unless Avon has come out with a new Cobra, stay away from the rear unless you want this to happen. Mine blew at 70 mph and I was able to get it to the side of the road without any problems. There are many reports of this happening to the rear on other GW forums. The tire only had about 8K miles on it at the time. Loved the tires up to that point. But no more Avons for me!

WoW -- Did you report this issue to Avon ?
What was their response ?
How many miles on that tier when it blew?
Was it sudden or gradual ? Did you feel it getting bad ?

After 4000 miles now on Bridgestones. Avon said they had no reports of this problem, no offer of a replacement or discount on one so binned it.

I found out about the issue after I returned home from the trip. They would not do anything unless they could see the tire. I left it at the dealer where I had it replaced.

It only had about 8K miles on it. It was only about half gone when this happened.

I could feel a vibration for a few hundred miles before it went. It was through the bars so it felt like the front tire was out of balance. I had a front out of ballance before, and it felt the same, so I did not think much about it. When it blew out and went flat right away.

From the pic, the tire had a separation and a bubble in it for some time.... I have a set of cobra's on my 2003 GW when I bought it last year. The tires now have about 9000 miles on them with no problem. I have pressure sensors on my tires thru my Zumo Gps. So I keep a close eye on pressure.... If the bike sets for a while, the rear tire will lose some pressure, so I have to air it up before a trip. I have noticed some cupping in both the front and rear tires. They are quite during normal riding, but noisy on turns... I use Dyno Beads for balance.
