NAIL IN NEW POWER

So did you burn the old one off and make some sparks with it first?

:twisted:

 

IMHO that actually would look pretty cool at night. I can't help admitting it, but it would. :lol:

 

Wimp. THAT kind of smoking is allowed!

 

nice avatar... how many cats do you have

 

its bubbles from the hit canadian TV show, Trailer Park Boys... he loves kitties, nothing towards you... just your avatar

 

you should catch the show sometimes... comes on showcase, a canook channel.



or video.google.com and type in trailer park boys. watch an episode or ten. its retarded

 

For some reason saying clean and having rubber on it just doesn't sound clean anyways :roll: :lol:

 

I change a good amount of tires and I will not plug or patch a motorcycle tire to ride on the street or track . Motorcycle tires are pretty thin plus as someone already stated , there are the wound cords that most likey got knicked if not broken by the puncture . Then you need to puncture the tire again to rough out the hole for the plug . Take into consideration the flex and abuse it takes under braking/cornering etc, why take the risk when you are on two wheels ? Murphy says the sudden loss of pressure will probably come at the worst opportunity . I have a fairly new Power Race rear right now on the R6 that was punctured last year at Tally . Its sole purpose now it to let the bike roll around the shop during the Winter months . Even it's coming off tomorrow since track season looms near .



Let's not even talk about liability issues if the person you hit because of that plugged tire finds out it may have contributed to the crash ....



Just because some have gotten away with something doesn't make it safe . Statistics show Jeffrey Dahmer didn't eat me , but that doesn't mean he wouldn't given time and circumstance . :shock:

 

opinions are like assholes.... the world is full of them... and everyone has one

 

Kylbie,



I don't have any proof that repairng a tire is bad but I won't do it for myself, a friend or customer unless stuck on the side of the road with a flat (I try to always carry tire repair kits when rideing .) I don't want to get hurt because of being too cheap to buy a new tire.



Worse, as a mechanic, the safety of the people that I do work for is paramount. Liveing with someone getting killed or injured after I repaired a tire is something that I can do without.



The big risk, as Darkside41 pointed out, is the unseen cord damage from the puncture and the repair. If you take the approach that, I can't see internal damage, so it isn't there, then you can blissfully repair punctured tires until the day you don't get away with it. Unless the damged tire is repaired and then X-rayed, we have no way of knowing how safe or hazardous it may be.

 

Opinions are just that and facts are facts . I'm pretty sure the tire manufactors have all the statistics you need if you contact them . Personally I've seen repaired tires fail at the repair so that's enough for me . Where are your statistics for your original post or is that mearly opinion ? Personally I would lean towards the side of caution when giving advice if all I had were opinion concerning a safety issue .

 

i don't need to contact any tire manufacturers. i have used many plugs in tires, motorcycle, ATV, MX, cars... never had one fail. those are my facts. are there going to be outliers that fail... of course... have you ever had a new tire fail... i had a brand new michelin truck tire seperated belts within 100 miles of buying it. i've had more than one friend with a new motorcycle tire seperate or chunk, those should be considered failures



So with all these thoughts of tire failures being a huge concern i guess i need to raise a question



How do you tech a tire after a crash, if it hits something it could pinch the belts and seperate without causing any damage to the rim. that is wayyyyy more of a hazard than any simple puncture and that would cause an extreme blowout.

 

The tech question is easy if not foolproof (most tech inspections aren't.)



A tire with a break is normally distorted. A crash that is hard enough to break the caseing will normally also damage the rim. Is it possible to damage a tire severely enough in a crash to cause a later failure without leaveing any other damage to point to it? Anything is possible. But that one is very unlikely.



The difficult part about tech and tires is what happens before they are on the bike. How many are damaged in the warehouse or shipping or by whoever mounts them?



No tech inspection can catch everything. To even attempt to would require complete disassembly of the bike. The point of tech inspection is to catch what you can and to attempt to motivate people to at least try to prepare their bikes. Without tech, many would do zero preparation and some would even put all the bad parts on for the track.



Also: In forty years of working on bikes, I've never personally seen a new motorcycle tire fail totally on it's own on the road. I've seen them rub fender bolts, get cut or suffer impact damage but never fail on their own. I have seen repaired tires suffer ply seperations when the air got inbetween the plys at the location of the repair. Fortuneately all that I've seen were caught before total failure.



Yes, I did see Mladin's tire explode at Road Atlanta (on TV) and have read about others on the race track. Very few of these left much evidence of what actually caused it. If the company found the causes, I've never heard of them releaseing it. How could they? If it was their fault they may not be sure and it could damage their reputation. Considering it's racing and experimental, that's part of the risk we take as racers. It would be unfair for street tire sales to suffer due to raceing problems.If they did find an outside cause it would sound like an excuse.



There are enough ways to get hurt on a bike wthout looking for more.



Actually most of the hurt usually happens after we are off the bike :cry:

 

So then why the statement in your first post telling him he would be 100% fine with a plugged tire when you just admitted some fail ? Your logic isn't making sense . You ask for statistics yet you state only experience to substanciate your own conclusions . :?

I've never been hurt at the track in a crash but that is poor statistics to rely on and state to someone that I never would . You've been lucky , I hope you continue to be lucky . Luck hurts sometimes though .

 

I have seen a plug fail. The plug hardened up and allowed a gap to grow between the original tire rubber and the plug rubber. This resulted in a slow leak and a tire low on air. The plug had been holding air for some time (more than 6 months) so it must have been installed properly (by plug manufacturer directions).



I've seen a tire that was ridden while low on air which when removed from the wheel had a lot of broken rubber pieces inside the tire (enough to fill two coffee cups). The pieces were worn from the side wall area from excessive flexing and probably heat too. This particular tire still had 18 PSI when the problem was "discovered".



I too have seen a plugged tire have no further problems and at least one I know was put on the track. I don't recommend this either. What price do you put on your life? The lives of those around you?



My biggest concern wouldn't be the plug but the unseen damage. Monte could answer the question but I imagine that's the reason for the rule. As Mike pointed out, don't take risks that you don't have to. Plugging a tire to get home and off the road is one thing. Continuing to ride on said tire (espeically the track where the stress is maximized) is another.
