Difference between Pirelli "Diablo" & "Diablo Rosso 2" "tyres" (EU spelling ;)-

[DuciD03]

Purchased, and just got delivered a brand new plain ol "Diablo" front tire from an on-line retailer for $114 Canadian; thinking it was a Diablo Rosso 2. Somewhat excited to get new rubber for the front, kind-a like a present for the bike, put it beside the front tire when I received it; ta da!.


What's the difference between Pirelli "Diablo" & "Diablo Rosso 2's"?; asides the obvious difference in tread pattern and slight difference in cost ($13). So if I have a "Diablo" on the front & new last yr "Diablo Rosso 2" on the rear … both w rated; there must be a bit of difference in rubber compound and what rubbers applies where on centre and cornering sides?

Part 2 question; Comparing the old existing & new "Diablo" tires, there's still a fair bit of tread life in the 10 yr old one; 1/2 warn. And what's up with moto tire age? Where do you check the age again?.

Omg that's an old tire...or a new flat track tire... the date code will be 4 digits first 2 will be the week last 2 the year...that said the rubber has to feel like a stick of lumber...get a new set all around and see if the museum's in your area are interested in the ones you got now...lol

to repeat rears newish.

… I hear ya; I did a thumbnail check on the tire before I bought, the rubber is still rubbery, but not as elastic as the new one. Just outa curiosity and not to be cheeky at all; cause it sometimes depends on the optics; are you a GP racer, do you own a shop or have business interests in sell Pirelli moto tires?

There does not exist a tire that I'd prefer at 10 years old over a new plain Diablo.

Plain Diablo or Diablo Supersport are a good inexpensive tire, they've been around forever.

But without a picture we can't know which ones you've got.

The Diablo is a single compound tire, the Diablo II is dual compound, harder in the middle, soft on the sides.  The object is to avoid squaring off and increase life.  Both are good tires.

What Buhgaboo is telling you is check the manufacture date.  Pirelli is up to Diablo III and often the bargain price catalogues are selling old tires.

Yes this is a car tire, but the coding is the same.

There is some dispute over how old a tire can be before it is not safe.  Opinions vary from 5 to 10 years.  I'm a conservative 5 year guy myself.

Two years ago I replaced the worn Diablo II rear on my Monster with a Diablo III... there was a marked difference between the two tires, particularly when they are cold.  But, as Speeddog says, a new anything tire is better than that washout special you are running now.

Date code.  It’ll be something like 3918 which would be the 39th week of 2018.

Will need a new rear this summer. What are the differences you noted between the II & III?

The biggest difference between ii and III is that they are both inferior to the power RS...I wish I got commission...you can full send the Diablo Rosso's into a corner and even riding beyond the tires limit your still slower than the RS...and if your at that pace...it will take 3 sets of tires for 1 of the Michelin...the thing is built in Hogwarts...it's impressive...you have got to try it

As I said before the Diablo is single compound and the Rosso II is dual compound.

@Charlie98 and I both ride 796's. Interested in the difference between II & III. Possibly profile or compound or something else. Have a D-spec III on the front currently which is newish.   (Worn Rosso II on the rear currently.)

[Howie]

Oops!  II and III.  Supposedly the III has a better footprint.  Usually, but not always, the next generation is better.  Unless $ are a big deal I would go for the III

I had problems with the II on warm up, it would step out on corners, and particularly over pavement markings and such... the III does not have this problem.  Comparing apples to apples, even when the II was new it did this; I embarked on a mad tire pressure search, thinking it was related to pressure.  I'm not going to say the III is track sticky, but it is an excellent sport tire, particularly compared to the II.

Thanks! Good feedback.

Truthfully, however, I only get roughly 2500mi/4000kM out of my rears... I really, really like to twist the throttle.  I don't consider that a problem... these days it takes me 2-3 years to do that, which is my cutoff for new treads, anyway, regardless of miles.
