    Admit I have no experience with going down on new tires nor finding them slippery. Probabbly more of a function of my less than overly aggressive riding style but if as most claim they need to be scrubbed in for safety reasons I think the entire motorcycle street tire industry could be held liable for all the reported faceplants.

    We live in a horridly litigious society and I have never heard of anyone bringing suit aganist a bike tire mfg for tires that were not "ready for the road" as delivered.

    Seems to the uninformed that if they needed to be scrubbed this would be done by the mfgs before delivery, or it isn't necessary. Simply stating that one should "take it easy" for the first 100 miles is not enough to ward off nor win a lawsuit if in fact the tires are inherently more dangerous during the initial run in.

    Possibly this was the case 20+ years ago but I'm just guessing here that with 2013 manufacturing technology that it does not hold true today.

    Go easy for the first 100 miles to get the tire thru a few heat cycles and get use to the different (and improved) profile, and rid it of any mounting grease/soaps, etc. Call it scrubbing in if you want.

    Ha ha. Should have read the next 10 words but maybe reading is hard.

    I've gone done before, and likely will again, but ever single time it was because I was doing stupid stuff, not because my equipment was unsafe or tires were new.

    Stand by my assertion that new tires are safe as delivered and need no special attention.

    We have tried to use molds that were teflon coated (not really teflon but similar) and they did not work well. The silicone is sprayed on after the tire is assembled.

    Contrary to belief, tires are not injection molded. Basically a tire is made of many layers wrapped around a drum. Tires start on a first step machine where they lay down the inner liner, nylon/polyester plies, set the beads, add another nylon/polyester layer, and sidewall. From there they go to another machine where the steel belts and tread are put on. Then they get sprayed with mold release before going to the press.

    Those little rubber hairs you see on tires, are from the vents in the molds. The more intricate the tread and sidewall, the more of those vents, and after the molds are removed and cleaned someone has to drill out each and every one of those. It can take hours.

    That's a pretty good point. I actually did a quick Google and didn't see a lot of cases. However, my guess is most of these faceplants occur at low speed and result in very little damage - relative to the cost of a lawsuit. So, if somebody leaves the dealership and falls and actually seeks redress - it probably gets settled quickly ("we'll replace your blinkers") or gets settled in small claims court and is never published. A serious injury or fatality would probably occur some distance away and it would be tougher to prove causation.

    But I am a bit surprised there isn't more cases. Even if it is a "myth", I would think there would be some unsuccessful suits. But I really didn't search too hard either.

    I've had the Aprilia head tech tell me they do not send out bikes for test rides with new tires until they are rubbed down with brake cleaner and a rag.
    In the past they've had bikes with new tires go down right away.
    He said brake cleaner removes all the mold release agent immediately.
    He recommended that be done with all new tire no matter the mfg.

    I must have dodged that bullet. Lucky you.

    Tuna, you're saying the silicone is sprayed on the tire after molding? So that puts the silicone on the outside and inside the tire?

    "Yea, thats it, My goal on here was just to be a total prick and not to help dispel a bullshit myth that does not allow people to be better riders.
    As long as you keep making excuses they will continue to suffer."




    One thing I still don't understand.... how does taking it easy for the first 100 miles on new tires make me a "bad" rider??

    I don't know why I read threads like this, but I just couldn't look away.

    I believe the basic process is that the carcass is built up from the belts, chords, rubber blanks, etc, then it is sprayed with silicone and put in a hot press to shape and imprint the stackup into a functional tire.

    And what is it, that goes horribly wrong, if I'll just take it very easy on new tyres for the first 100 miles or so?

    From what I gathered, ol' looney toons thinks that it will forever besmirch your ability to ride "properly" and use the full potential of your tires in the future, or some such drivel-like nonsense.

    On a less sarcastic attempt:
    He means that 1) there's a chance one needs to use the full potential of a tyre at the first few miles. For example when a kid jumps on the street directly in front of you or an oncoming vehicle uses your lane in a corner so you have to lean more or maybe brake to avoid a collision or whatever. Thinking the tyre has less potential than it actually has might in that case lead to a crash that could have been avoided either because one didn't brake/lean hard enough or was not relaxed enough to do it smooth.
    And 2) if something happens one might falsely blame the tyre instead of honing your own skills.

    By the way, I find it funny that the "oh you're lacking reading comprehension if you don't agree to me"-guys have such problems understanding what the other one tries to tell them.

    If I ever start a thread making such a bold claim and stating what can and what can't happen on any given topic, I would fully expect a rain of incoming reply hellfire to show me the error of my arrogant ways. :lol3

    Sarcasm is in full effect with this guy. :D

    Before it goes in the mold. Outside meaning on both sidewalls and the tread surface, inside meaning the part that holds air. I'll see about some spy video.

    These are UK made Dunlop SS tires offered by my regular vendor. The US made version is the 211GPA. Pirelli makes something similar, as does Michelin. They are DOT tires legal for use on the street. I wanted to post this because some here think race tires are somehow different from DOT tires. They are, but not in the way most think.

    I wouldn't recommend using DOT labeled race tires on the street, however. They would be very slippery because they won't come up to temperature riding around the neighborhood. :D

    Sorry to hear about your crash, but those scuff marks are what a tire looks like after it slides along the pavement during a crash. Sadly I know that all too well. Scrub, don't scrub, whatever, but I don't think you can determine the cause of your crash from those photos.
