Pirelli tire selection

The 180/60 may follow this path too

But maybe if Kramer moves their 180/55 bike to a 180/60 the 180/60 slick will remain in a couple of compounds, but who knows?
When I ran the show it came down to this. If I couldn't sell at least 100 of a size/compound in North America in a year why should I import them? And if all you fickle racers saw a tire that was like a year and a half old you would bitch. So put yourself in your vendor's tire truck for a minute...

 

The 690 Kramer won't accommodate the 180/60 rear without either an offset drive gear/rear sprocket/rear wheel. 180/55 SC1 are generally available in the US these days. The 890 Kramers and KTMs (KTM-badged Kramers) are built around the Pirelli 180/60 rear. SC1 and 2 rears are available. I don't know but suspect the 190 will fit the bigger bikes because the width is nearly the same.

 

From your experience does age matter in a race tire if stored properly?

is there an expiration date, or is super fresh hot off the line tire better than one that’s a year old?

Any way to know if they are not stored properly?

 

No shit and my point was IF Kramer changes their bike that uses the 180/55 so it can use the 180/60 that may help keep the 180/60 from going bye, bye. Simply put there are a zillions variables to consider here so...

Who knows

 

I remember when Mike Smith won a AMA 750 SS race against the evil empire and ALL of the factory supported teams at Road Atlanta on a set of 2 year old Supercorsa DOTs, and before that everyone said 2 year old tires suck. And sorry I've posted 3 or more times about tire age and correct storage methods on the BBS and I'm deep into a 2 hearted IPA so I'm tapping out.

 

Offset sprockets are EASY to source, if that's the only obstacle.

 

I talked to Joe at Kramer about this a couple years ago and he said changes to accomodate the 180/60 were done by them but they didn't notice any performance improvement.At that time they lots of 180/55 in stock.

 

Yep! The 180/60 weighs appreciably more than the 180/55 and just doesn't add enough edge grip on a sub-300lb bike to overcome that disadvantage. Trade-offs. The 180/55 has been readily available for the last few years so we haven't been compelled to use anything else.

 

Hi @Pneumatico Delle Vittorie , QQ: can the Diablo Supercorsa SC3 DOT rear tire be flipped when being used in dry conditions on track? TY!

 

I know you're not asking me but I wanted to chime in and say that I've done it. I've also seen others do it with the SC3. I flipped mine after some cold tearing on one side in an effort to even out the wear a little.

 

Depends on the construction of said tire so I'm not sure, sorry

 

Thank you! Appreciate the data point.

 

How would I go about identifying how said tire is constructed (in a practical way)?

 

Are you asking because at least one tire guy that sells Pirelli is now refusing to flip rears?

 

Nope. Is that a thing? Refusing to flip the track day DOTs?

I'm asking because I have a fairly fresh set of SC3 DOTs on my bike and wanted to know if I can flip the rear as I can the SC3 slick rear tire.

I don't plan to ever ride the DOT tire in the wet and had ASSumed that the tread in the SC3 DOT was mainly ceremonial to gain DOT approval. Hence I was led to further ASSume that flipping the rear tire may not (should not?) be an issue.

 

There's no ceremonial creation of a DOT tire! To designate as a DOT approved product a tire company MUST meet the industry testing standards and my former employer takes that seriously

 

A tire guy is refusing to flip the Pirelli slicks because they have a directional arrow on the sidewall.

 

I assume you were at the N2 day. He was playing it by the book until he talked to me because he's doing things 100% to the letter of the law because I told him that's how we do things.

I didn't tell him the current construction tires were safe to flip, so that's on me.

I was out walking in the woods with the dogs when he called me for confirmation and my phone was nowhere near me. I spoke to him, and it's good to go. He was doing what he thought was the right thing by you. If you want to spark up your ire, direct it my way.

 

I only use Dunlops.
