Member Contributer Fritzer Posted August 29, 2021 Member Contributer Share Posted August 29, 2021 About a month ago I was riding along and heard a loud commotion at my rear wheel area. A little jitter and as fast as it came on, it went away. I pull over right away and see that my pyramid hugger fender has been ripped off its mount, but no clue what caused it. I take a bungee and set it up to hold the fender from running into the tire while I ride home, some 8 miles away. After putting the bike on the lift, I see that culprit. A 4" duplex nail at a shallow forward facing angle imbedded itself into the tread portion of the tire but never punctured the case. It stayed in even after it ripped my fender. So, other than my lost fender, it was a easy pull the nail and ride. No plug required. While I'm at it, does anybody have a hugger fender they no longer want? If so, let me know.

Member Contributer Marooncobra Posted August 29, 2021 Member Contributer Share Posted August 29, 2021 Fritzer Wouldn’t it be great if, as well as having road sweepers, the council had magnetic sweepers that drove round and collected all of the nails, screws and other ferrous debris that is the curse of Mr Dunlop’s invention from our roads. Sorry for your woes. I would suggest that although the nail didn’t go all the way through, noting how the structure of the tyre wall is critical for cornering, I would replace the tyre for peace of mind. Last thing you want is it to let go as you are rounding a high speed corner. A shame, as from the photo, it looks a fairly new tyre.

Member Contributer Fritzer Posted August 29, 2021 Author Member Contributer Share Posted August 29, 2021 Good advice for the tire change. I'll probably take that route. Link to comment Share on other sites More sharing options...
Member Contributer BusyLittleShop Posted August 30, 2021 Member Contributer Share Posted August 30, 2021 THE CHOICE The choice is yours but I'd start plugging because there is mounting evidence that plugged tires work and are safe... I have yet to note anyone armed with first hand knowledge to the contrary... REPAIRS Minor tire repair is limited to an area of three quarters of the normal section width. The maximum diameter of penetration damage and/or cracking at the base of the injury should be no greater than 3mm. The repair patches must not overlap. For permanent repair,it is only recommended that small punctures restricted to the tread area be repaired, using a rope type plug. The current condition of a tire is important in determining whether a tire is suitable for repair. Some damage limits include: if the tire has reached its minimum tread depth as indicated by the TWI (tire wear indicator); ply separation, separation of inner liner and or cutting of ply cords by penetrating object; brittle or cracked rubber caused by exhaust heat; broken or bent bead wire, damaged bead zone; damage caused by under-inflation; softening or swelling of rubber due to oil or chemical attack; punctures too close together; damage or previous repair of a puncture outside of area specified for suitable repair. MY EXPERIENCES My screwed Rennsport... boo hoo... My plugged Rennsport that covered 2K miles and not in moderation either... it's seen over a 140 mph more than once... Inside the Rennsport for proof that the rope type plugs stay intact whereas my mushroom type plug started to come unstuck... You can see by the diagram that Safety Seal plugs that are installed properly establish an mushroom shape inside the carcass that holds fast under pressure... you'd have more luck pushing the plug inside carcass than you'll ever have it pop out under pressure... Self Vulcanizing Ropes are convenient to buy and convenient to install for the Do-It-Yourself owner unable to locate a shop to assume the liability of a inside Combi Plug for such little profit... 3 Steps on the rode again Self Vulcanizing Ropes... Rope1) Ream hole with tool provided in the kit found at any parts store Rope2) Insert rope with tool provided in the kit and trim excess Rope3) Inflate tire to proper PSI I don't recommend the inside Combi / mushroom type plugs because I discovered that the inside patch is solely dependent on a bond between a plug company's material and the tire manufacture's rubber compound... that's a crap shoot the two chemical compounds are compatible enough to hold a bond when the rubber is stationary and at room temperature... but tires are elastic bodies designed to flex from completely round to completely flat at every rotation... every rotation builds heat that works against that bond... every rotation flexes that mushroom patch from round to flat that works against that bond.... so we have heat coupled with flex working against the two competing chemical bonds from being as consistence as a self vulcanizing rope plug installed from the outside.. 7 difficult steps for a due-it-yourself or for a shop to install an inside Combi Plug whereas the Self Vulcanizing Ropes are convenient to buy and convenient to install for the Do-It-Yourself owner unable to locate a shop to assume the liability of a inside Combi Plug for such little profit...

Member Contributer Fritzer Posted August 30, 2021 Author Member Contributer Share Posted August 30, 2021 I have been using plugs on flat tires for the last 6 or 7 years. What a great technique to repair tires. It is a rare event that requires taking my tire in for flat repair, and if I have to take it in, they don't usually want to repair for liability reasons. Not to mention the ease of repair while on the road. Don't forget to bring the compressor with you! Link to comment Share on other sites More sharing options...

Not to mention the ease of repair while on the road. Don't forget to bring the compressor with you! For the last 12 years or so I have carried a Slime mini compressor on my bikes along with the tools and plugs. The compressor fits nicely into the left upper part of the fairing on my 3rd and 4th gens, The plugs and tools are in my Tail bag. On my V65 Sabre I hard mounted a compressor to the bike with a switch. Large swaths of Maine, and northern New England have no motorcycle services along with no cell service as does parts of the west in Utah, Montana, North Dakota etc.. Better to be self sufficient than stuck in a lonely place.. Used it once myself, then on some Harley in Colorado, then a Camry in I think, Quebec.

Member Contributer Thumbs Posted August 30, 2021 Member Contributer Share Posted August 30, 2021 Any repairs to a V rated tyre is only permitted on a “get somewhere to replace the tyre basis” in the UK Its illegal for a tyre company to repair the tyre and your insurance is invalid if you do otherwise Link to comment Share on other sites More sharing options...
