A worrying tyre issue

by Ed Quayle

All ready to leave Chester

All ready to leave Chester

Plans for our European trip this year started with working out where we all wanted to go, what hotels to use, what sights to see, what roads to ride, etc. and after a few changes of direction all seemed to fall into place nicely.

One of the things I did not even worry about was the tyres on our GoldWing. We had new-style Avon Cobras fitted last year just before we all went to Scotland, and I worked out that we had only done about 3,000 miles on them since then – thanks to the bitter winter! In fact, my Wing had been taken off the road for winter and so sat unused for about 4 months. When I came to put it back on the road in the Spring I noticed the tyres had lost pressure – as I would have expected them to do, being sat there for so long.

Once the pressures were restored there were no issues with the bike, but I had noticed a very slight trace of Ultraseal leaking out from the rims. I know my rims need powder coating soon so I thought: get the European holiday out of the way and come next winter I’ll have new tyres, powder coat the rims, etc.

I thought it might be a good idea to remove the wheels before we went abroad in order to have the rims cleaned up inside and the tyres refitted – so I knew there would be no leakage issues. I therefore removed the wheels and gave the tyres a really good looking over before taking them to be done. The front tyre still looked like new and the rear also seemed fine – it was not squared off in any way, so looked great for the trip.

So, tyres newly mounted, Ann and I set off for our holiday along with Nigel & Jo (who coincidentally also had the same new-style Avon Cobras fitted on the rear at the same time as we did last year), plus Dave & Jan and Ian & Val.

About 500 miles into the holiday, I started to notice a slight wobble in the handlebars on starting off from rest. It went away at about 40mph, and I initially thought it was because we were two up, with luggage, etc.

"Something's definitely wrong with this tyre!"

“Something’s definitely wrong with this tyre!”

As the holiday progressed, it got a lot worse and at one point I thought my front wheel was loose – it was that bad! It soon got much worse and the other riders with us could actually see the rear of our bike moving about an inch side to side! The tyre also started to get really noisy and at 70 mph the mirrors were shaking!

Close examination showed the problem to be caused by severe cupping of the rear tyre. Dave Turvey had this happen to him last year after he got back from the Scotland trip, and he had set off with a new Avon as well.

I would describe my knowledge of motorbikes as above average and I am a qualified mechanic, but I have never seen a motorbike tyre deteriorate this quickly or give such a bad riding experience.

As our tyre had got progressively worse, Nigel’s rear tyre started to show symptoms like mine had done a few hundred miles before (he described it as “a wicked handlebar wobble, worst going uphill at 30mph”) – so we knew it was only a matter of time before he, like me, would be forced to buy a new tyre.

Some of the roads we tackled in snow and fog!

By this time we had arrived in Austria for a few days stay, so we thought it wise to start a search for replacement tyres (preferably not Cobras!). After several unsuccessful attempts to locate someone who could supply and fit before we moved on to Germany, we tracked down a GoldWing specialist by the name of Ernst Schick on the outskirts of Innsbruck (http://www.goldwing.at/), but his shop was always closed on Mondays….. and guess what day it was!

As we were only half an hour away, we decided to ride there anyway – just in case! Sure enough, the place was closed, but as we were looking through the showroom window a car pulled up alongside the workshop. I went to speak to the lady driver and asked if she knew if they still specialised in GoldWings here. “Oh yes”, was the reply – “it is my husband’s business, I will go and speak to him”.

The Schick  shop!

The Schick shop!

After a few minutes, Ernst Schick himself came out, shook our hands and patiently listened to our tale of woe. He then took us into the shop to confirm that he had 2 Bridegstones in stock and to check his bookings for the following day. He confirmed that, if we could be there for 8am, he could fit two new tyres.

After picking Nigel up off the floor at the mention of 8am (he likes his beauty sleep!), we told Ernst that this might be a bit hard to do as our hotel was over an hour away – but I offered instead to buy the tyres there and then and take them with us (I figured the women could carry them on their laps!). I told him I would remove the wheels myself and take them to a car garage to see if they would let me use the tyre machine – and I could then fit the tyres and put the wheels back on.

"Hmmm...this is nearly as nice as my own garage!"

“Hmmm…this is nearly as nice as my own garage!”

He looked at me very puzzled (I don’t suppose your typical biker knows how to use tyre machines, but I had used them many times in my career as a car mechanic), and then picked up his phone and after a very quick chat I thought he was arranging a garage for us to go to…. but no. It was just after midday by now and he said, “Come back at 1.30 and my son Armin will be here – he will fit the tyres for you. Now go down that road and you will find a couple of good restaurants where you can have lunch while you wait”!

Wow! We were very impressed, so off we went for lunch – which turned out really nice, sat outside in the sunshine eating Hawaian toast – and we then returned to the shop. They had already removed the bikes from the workshop and were ready for us, so Armin jumped on Nigel’s bike, full of confidence, and rode into the workshop. He kindly allowed us in so we took lots of pictures of his wonderful, spotless workshop – one to be proud of.

Lots of safety-chrome!

Lots of safety-chrome!

A short time later and a new Bridgestone tyre fitted and Armin pushes the bike out of the workshop, jumps on and starts it up ready for a quick test ride. However, before setting off he says, “Xenons?”. Nigel replied, “HIDs – but how do you know just from sitting on the bike?”. “Oh, I can hear them start up”, he says!! And yes, you can (we tried later on). Anyway, after a quick road test he puts the bike onto the centre stand like it is a Honda 50!

My bike next, and again a short time later another new tyre. After the road test, I see him bouncing the front suspension. I thought he had worked out that I have progressive springs, but no – he asked, “did I know the anti-dive was not working?” I told him I did know, as I have blanked it off (like many GL1800 owners do).

Into the shop to pay and we were even given a discount on the bill – and it was more than a fair price for what they had done.

There are a few reasons for writing this article, but the main one is to again thank father and son Ernst and Armin Schick for going above and beyond in providing customer service. Opening on their day off, fitting the tyres so professionally (I saw how careful Armin was), not using the opportunity to overcharge us……. Outstanding!!

If you are ever in this part of Austria, go and give them a visit. They have lots of chrome goodies in stock, plus clothing and new bikes – and they certainly know their GoldWings.

You can tell from the photographs of the tyres below just how bad they had become. I have never seen this before and I will never use this make of tyre again on my GoldWing.

This is now 3 out of 4 Goldwings which have had this tyre seriously deteriorate after all being fitted at the same time – which is shame because the Avons fitted before this were superb and I got over 10,000 miles from my rear one (and it was not illegal when it was removed).

Our bikes were fully loaded but not overloaded, so I don’t think the problem can be blamed on how we were using the tyres. I wonder if anyone else has experienced anything similar? If so, please send in a comment below .

  1. New avon cobra fitted 6 weeks ago to rear of gl1800. approx. 1500 miles later slight wobble to handle bars which became a very serious shake at 50 – 70 mph. New tyre fitted now all ok .Looking at tyre taken off noticed a fig.2 printed inside of tyre now wondering if this means its a second?
    Feel I have just wasted £130…………….

  4. If you run cobras at honda pressures they are low avon pressures are higher

  5. Have exactly the same with my cobras thought it was a u joint going south. My Avon has done less than a 1000 miles and the tread pattern feels like. A water wheel scoop . It must be 2or 3mmhigh at some points . Causing all sorts of handling issues . Come back Dunlop’s all is forgiven .. also what pressure should Avon’s be run at as no mention. If this from suppliers

  6. Thanks for sharing your experience. I have just started having the very same issues with my 1800 Goldwing. After searching the web for possible answers I should have thought to look at a local Goldwing site. Just need to get the tyres sorted now in time for Llandudno light parade in just over a months time. Looking forward to seeing everyone again. Think your article proves how sharing issues can help others. Thanks again.

  7. Two years ago myself and another couple set off to do the Spanish Treffen on our 1800’s. I had 2 brand new Avons fitted for the journey. During the return journey our friends wing developed the wobble. I was aware of the possible tyre problems so we checked his tyres and found cupping on the rear tyre. He replaced this when we got back but then I checked my new tyres and found my new rear tyre cupping also. These tyres had only done around 1200 miles after the journey so I contacted Avon through the dealer to complain. I had to return the tyre for them to inspect and they eventually refunded me part of the tyre cost. It was a load of hassle that I don’t want to go through again. My tyres were not under inflated but the wing was loaded up with bags and a greedy rack. I often wondered after this if the tyres are load rated high enough for a fully loaded wing? Needless to say I will not be putting Avons on again.

  8. Had the very same problem this weekend on my 2012 bike, tyre has done about 3000 miles and started as a slow weave from 20 – 40mph then seemed to go, cornering wasn’t affected which was good. Now have to replace a tyre and am sceptical about putting another Cobra on, any recommendations on a replacement?

    I have replaced the tyre but not with another Cobra, I have put a Bridgestone on. As you (company) seem to be in total denial even with others experiencing the same problem, I will not buy Avons in the future, as everyone else has decided. I can’t afford to replace a tyre on that mileage everytime.

    Hi Dave,

    Have you changed for another Avon Cobra?

    Increase the pressure slightly to 41 front and 43 rear and feel free to keep us posted with mileage.

    I check the pressures before every ride as it’s only used weekends unless we go away, It’s a Honda Goldwing. I’ve attached photo’s of both tyres for you to see.

    As the link on bottom email I am not the only person to have had this problem and have had to replace the tyre, no longer weaving

    It’s odd there has been no issue for 4,000 miles/3 years and its presented itself only in the last few weeks.

    How often are you checking pressures?
    Do you ride with pillion and/or luggage?

    It may be worth increasing the pressures slightly to 41psi front and 43psi rear.

    Are you able to send any photos of both front and rear tyres?

    Many thanks

    Rear tyre is the problem, and, the problem is all over the Goldwing forums as LOTS of people have had the same problem.
    The size is 180/60/R16 and I run it at 41psi rear – 39 front, Went on as a pair and the front is fine. I consulted a friend who is Chairman of the Goldwing Owners Club who told me the problem and it has become widespread.

    Please see the link for more on this problem

    Thank you for the below email.

    Please can you confirm on the below points;
    1) Is it the front or rear tyre that has cupped?
    2) What sizes are fitted to your bike?
    3) What pressures are you running for both front and rear?

    Please note we are not aware of any issues of our Avon Cobras for the Honda Goldwing.

    Many thanks,

    Avon Motorcycle Technical

    I have a cobra on the back of my Honda Goldwing which has cupped after only
    4000 miles, it has been on the bike for 3 years and had no problem until 2 weeks ago on a trip to Wales when the front began to weave.

    I contacted a friend (Chairman of the Goldwing Owners Club) who told me what it was, and checking the tyre proved it. Looking on the forums it seems a lot of people have had the same problem on this tyre.

    I now have to buy another tyre at a large cost that I shouldn’t need to buy for at least another 4000 miles.
