New tire ride...
« on: March 07, 2015, 09:11:52 PM »
When I install new tires it has been my practice to run them for two heating and cooling cycles of ~ 50 miles each before I can trust that the mold release compound is sufficiently off the tire to lean the way I like to...

So, a blast straight up the 15 (as they say in CA) I usually dislike running up the slab but for this exercise, it works.

I needed fuel at about Vista and as I tooled through town to the Chevron I noticed this joint...  Good grub.

Tires are all scrubbed in, ready for another ride with the SoCal Guzzi-Philes...  ;D  Have fun out there.

Best,
Rob

Pity I didn't see you on the 78 heading East toward Vista, Rob.  I had been lurking out behind Barona on my 03 Stone and was coming back to Oceanside around 12:30p.  Locked in 4th gear.  East of Rancho Bernardo on Highland Valley Rd I suddenly had no gearchange lever.  The clevis pin on the linkage to my Tarozzi rearsets had "gone away" and the lever just rotated downward.  Found a nail on the roadside and used it as a temporary pin which resulted in a lot of slop in the linkage, couldn't change down but could change up!  So, struggled over to the 15 in 2d gear and changed up to 4th for the ride home.  At my exit, I pulled over and manually shifted down to 2d and used that on the last 3-miles of surface streets. 

Whatever gets me home is all to the good.  Problem fixed 10 minutes after arriving home.

Most manufacturers do not use mold release anymore nor have they for a long time. The break-in period is more to get you accustom to the new tire and its sharper profile.

Last year at Deals Gap I had my Yamaha DT100 with brand new Avon Roadriders.  I didn't hold back on the Dragon, and I think I noticed a small amount of chatter at severe lean angles for the first trip or two, down to the overlook and back.  On later rides I didn't notice any more chatter.  My conclusion was that maybe there's a small effect of some sort for the first few miles, but it's not much.  Those particular tires certainly weren't slippery at the beginning or anything like that.

That is a great tale on how to get home, good deal Ralph.  BTW, I did take 78 back to 15.  

Most manufacturers do not use mold release anymore nor have they for a long time. The break-in period is more to get you accustom to the new tire and its sharper profile.  

They may not, I dunno...  The process makes me feel better.

I did take a slide once back in the day with one of the Hawk GTs.  I had just put a new rear tire on and went to a Scout meeting, leaned into one of my favorite, double fall line (pun intended) hills and the Hawk just slide out from under me.  My fault for diving in that aggressively that soon.  Thanks goodness it was a slow speed, in town speed limit slide.

Just for the record, the ME 880 is more round in profile than sharp...  at any rate, yes, different than the old tire that had worn tread and flatter in the center.

Matching tires are a great thing.

Not doubting that at all, but wondering when that changed.

Guzziknight here dropped his EV years ago within yards of leaving the dealer with new tires.  Made me a believer real quickly.

Again, without doubting this, have to say that my Norge's new MP3's felt, when installed last fall, "slick" all over.  Imagination?

And, "as we speak," my brother is at Riders Hill in Dahlonega getting new Avons for his C14; I was going to chat with him about "let's be careful out there" with those new (slimy) tires.  Not true now, huh?

Keep warning him Bill.


All tires use paraffins and/or waxes to protect the sidewalls from UV and ozone rot. As the tire flexes, those compounds work their way to the surface and protect the tire. If a tire is not flexed, they don't show up on the surface, and you get dry rot. When a tire is first molded, a lot of those compounds are on the surface, making it slick.

Believe what you want. I have experienced it, and I know people that have. Last summer I was sitting at the tire shop at RidersHill. A fellow came out and climbed onboard his KLR with new skins. When he went to ride off, he did this awesome unplanned doughnut and crash.
Blame it on mold release. Blame it on waxes. Or even blame it on the fact that new tires or 'smooth'. It sure isn't simply a matter of 'getting used to them'.

Only a few years back I couldn't get my go to choice of tire and needed one ASAP so the bike shop got me a Michelin Macanda, trailer bike home due to swmbo was too busy to give me a lift to get it. Rolled said bike from trailer, geared up and shot down my gravel drive like normal. When the rear tire hit the street during a hard left turn out of the drive the ass end passed me and down I went wondering what the f*** happened for a moment.
I'm a good rider and not proud to admit it but it happened and thankfully there as opposed to somewhere else. That tire kept getting little balls of rubber and felt slippery for the first 300 miles but finally broke in and was fine afterwards, remove it by 600-700 miles and gave it away. I'm a bit more cautious these days on new rubber!

hey I went riding last week and thought the handling was a little sluggish.  I checked the tire pressure and had 22 lb in front and 15 in the rear.  Aired them up to 36/40 and shazzam(!) handles like new tires.
