Shinko 705 unbreakable bead

I've been trying to break the bead on this Shinko 705 rear tire for two hours now. I've used multiple spoons, half a bottle of dish soap, a C clamp and as much force as I can muster but that bead won't break. I'm going to take it to the tire shop and have them put it on the machine. The original tire that came on my KLR was very easy to remove. A little bit of soap and then I stepped on it...came right off.

Is it normal for these Shinkos to be so difficult to break loose? If so, I need to think about getting a different brand/tire because I can't see going on a long distance trip and then expecting to change a tire.

I'm guessing that it might have something to do with the Shinko 705 being a tubeless tire. None the less, it's unacceptable for anyone who wants to change their own tire to have to fight with something for so long.

Finally got it off. Ended up having to cut the tire at the bead and then pry it away from the rim....both sides. Anyone in the Houston area want to buy a new Shinko 705? I'm going back with OEM.

The Shinko is a fairly well-respected tire. Quite a few tires are known to be difficult to remove due to a stiff sidewall.

[rant]
Often a tire will get stuck on the rim, perhaps due to the wrong lubricant being used to install it. Many folks insist on using Windex, WD-40, dish detergent, boogers, and all sorts of other 'lubricants'. This in spite of the automotive aftermarket industry making proper tire lubricants such as Ru-Glyde (which stands for something complicated like Rubber Glyde). Rather than spending the same amount of money that a gallon of oil costs and having enough of the slippery shit to pass around the neighborhood for several lifetimes, people insist on using what are essentially corrosive chemicals (detergents contain phosphates that aren't nice to aluminum, Windex is basically watered down ammonia, WD-40 is a light petroleum oil, boogers, erm, I'll stop there. Do any of those things sound like a good thing to put on rubber or aluminum?). Perhaps yours was stuck on for that reason.
[rant/]

My rant notwithstanding, I think going back to OEM would be a mistake. They are far more expensive than necessary and don't last for shit. Get a proper tire lubricant and put the Shinko on. If you are really put off of the Shinko, then a Kenda of the K761 sort might be a good choice. K761s can be had for $100 a pair delivered to your door, work well enough in all conditions for most folks, and the rear will go at least 9K miles, the front three times that (though I'm usually ashamed after 18K miles and put a new one on).

Anything but the OEM Dunlop.

I bet it works wonderfully and I'd like to have one as well as a tire changing stand. What I try to do is use the tools that I would be carrying with me on a long ride and unfortunately I don't have room for that on my KLR.

The Shinko is a good tire for the price and I have been happy with it. My only issue is the difficulty in breaking the bead during removal. I go out to West Texas often and there isn't much shade out there and fighting with a tire isn't a win/win. Part of the reason I decided on the KLR was the ability to fix things out on the trail. After this set of Shinkos I'm going back to stock tires for the simple reason of them being easy to change. Sure you have to take price, value, longevity and handling into consideration but that's not everything. The ability to conduct field repairs is important to me.

1) I have a tool like Patroy shows (mounted on a stand) but I managed for 40 years without one. At various times I've used dead blow mallets, hammers, MX boots, etc. Never had a bead I couldn't get off. I always spray some WD on the bead first......which brings me to:

2) In a rare occurance, I will disagree with my esteemed collegue, Tom......there have been lengthy debates almost everywhere on tire lube including an extensive one on ADVrider. I've used WD40 for a few decades now only because that's what all the other racers were using and because Ive had no issues with slippage or corrosion. There were several MC shop mechanics that stated they've used WD40 to mount tires for 20-30 years. While it may not seem logical, I'd suggest this is one of those "the proof is in the pudding" things. I guess its the same basic argument people have about using WD in lieu of chain lube...

3) having the bead stuck may be a pain for a tire change but it's a good thing when you're riding so....

YMMV

@DPelletier, I would have to push back on that. I have been using Ru-Glyde for years and have never had slippage, corrosion, difficulty breaking a bead, or tires that smelled like fish. ;^)

And to the OP, there are many tires that are as easy to dismount as the OEM tire and which will out-perform it in every category. The Kenda K761 is only one of them.

I never said Ru-Glyde wasn't good, only that WD40 works well. If this is the only thing we disagree on, I'm happy. .......oh wait, I would never have removed my starter, either!

I agree on your tire comment. (see, I can be reasonable!) LOL

Cheers,

Dave

I replaced a Shinko 705 rear tire just a few weeks ago. I struggled for 30 minutes using all kinds of methods without luck. It wasn't until I turned over the tire spoon, that I could slip it far enough down between tire and rim and leverage/push the bead over the safety bump. Using the same technique, it just took seconds to do it on the other side. Before I got started, I did go for a short ride to warm up the tire, and I used tire lube.

I am fairly optimistic I could do it on the side of the road.
