Proper scrub in

rangerbrown · April 11, 2006, 03:59:07 PM

i brokein my new rear tire at deals gap, the first day was... scarry as hell, then i found out the front tire was about 10psi low to what i keep it at, and the rear would "walk" kinda like drifting in a car.

good thing i have lots of dirt riding on my gs, 3 mile dirt road. every single day to get to a paved road.

its cool as hell to get sideways on the gs in 4th gear. but you must remeber not to lean in the turns as that leads to bad things.

Pirelli's pretty good about their release compounds and glazing. Both Pirellis and Dunlops I just hit with some 80 grit sand paper...works fine. Others, like Bridgestones, I give a good work over with the sand paper and then go do a couple figure-8's on some clean asphault. Works great.

really? I think I might try that

Just make sure the surface is really dull...the slick stuff is the shiny glazing that's left on the tire from the molding process.

no you can do a small burn out . as the tire is spining lean to the left then lean to the right . it will do its job . then you will only have to go about 25 miles before you can really get on it .

( oh and dont worry just keep control of the bike and it wont jet off on you

i know . when i drag race my gs thats what i do to warm the tires up

but it helps a little )

wow I got alot of good info. putting it all together this is what I'm going to do.

mount the tires tomorro, bring them home and finish painting the wheels, sand the tires abit, then mount the wheels thursday night and take the bike over to a parking lot to do some slow figure eights. then still take it easy on them for about 100km

also, the weaving motion does nothing for the tires, new or not.

ah..Man..

Well along with my new front end, I'm installing a new set of Pirelli Sport Demons. I know when you put new tires on they are very slick and need to be properly 'scrubbed in' before you go to crazy in corners. How many miles does a proper scrub in involve? Is there any specific tricks to doing this?

The proper scrub in as you refer to requires you to run the tire for enough time to heat up the tire to allow for any factory applied tire protectors or oils and the likes form the tire mold to burn off.

You do not need to sand your tires with sand paper?

??
You do not need to do burn outs?

?
You do not need to do anythig stupid to your tires?

?

Just ride the bike on the highway for for an hour and it should heat the tires up enough to burn off anything on the tires.

What do you think they do with race bike tires?

Ride them for a 100 miles to scrub them in before they can race on them?

No, they get a warm up lap or two and then they race on them. How long is a lap? At most 3 miles! So lets say they do three warm up laps that would be less than 10 miles.

So just take it easy for the first hundred miles and you should be OK. Being that they are new tires double check the tire PSI and get use to the new feel of the tires before you begin to push it.

Perfect advice for anyone who likes spending a day riding like a wuss.

None of the suggestions in this thread were intended to be mandate or processes deemed "necessary"...you're taking it a bit too seriously. There's more ways to scrub the release compounds off than "taking it easy for so many miles" or "running a few practice laps"...

mak, that was unnecessary. totally unnecessary language. chill out and keep it civil.

makenzie71 · April 12, 2006, 05:05:40 PM

Fixed. Oh, and there was nothing "un-civilized" about my post...sorry if that's the way it come across.

(I honestly didn't think the "p" word was that bad here...considering how many times it's posted without reprimand...)

pantablo · April 12, 2006, 05:13:01 PM

its always reprimanded if its not in TD. That word is inappropriate. thanks for fixing it.

Well the wheels have been primed, and I mounted and balanced the tires today. I'm going to finish the black paint tonight and mount them on the bike tomorrow night. Thanks for all the suggestions and maybe I'll add an hr or 2 of highway riding into my scrub in time for good measure. I think I can handle riding like a wuss for one more day.
