First Impression Pirelli Diablo Rosso Tires

[DAVE R6]

Motorcycle: 2007 R6
Road: Santa Cruz Mountains
Tire Pressure: 40 PSI rear and 38 PSI front.
Previous Tire Used: Michelin 2ct

After breaking in the tires yesterday and giving them a good rub, I took some time to test them out up in the hills on some nice twisties.
My first impression of the Diablo Rosso's are the improved stability compared to the dual compund tires. The one thing that I did not like about the Michelin's is that the large amount of "bumpy" feedback that I got was uncomfortable in the canyons. The Rosso's are a slightly harder compund all around and yet there is an inch worth of tire on the lip that is completeley bald. It provides excellent grip and warms up really fast. Overall the Rosso's seem really sticky and "controllable" when the bike was leaned over hard and felt very, and I mean very solid at high speed turns. Personally, I already like them better than the Michelin's because of the comfort factors that I listed. While I have not been riding for ten years like alot of you guys I have developed a keen understanding on what does an does not make me comfortable and these tires defenitley boost my confidence. Can't wait to try them out at the track!!!

38 and 40??? On an R6? Geez. I run 36 and 40 on my ST. And I weigh 275 lbs fully geared up and the bike weighs 725 fully gassed.

Aren't those numbers a bit high?

Aren't those numbers a bit high?

Ditto.

For the street, I keep my tires at 30/30 for more surface area. I sacrifice tire life, but I'd much rather have the grip.

tire pressure

Felt great....I would rather be smooth and hold a nice line rather than trying to waste my tires on going faster than I really can. 30 psi obviously means your the one riding in the hills like a squid trying to smash around every corner. I have been riding with people that are track junkies and have been on a bike for 20 years. I think I am ok.

 

[mototireguy]

Recommended middle weight bike tire pressures should be more in the ballpark of...

32-34psi front.
34-36psi rear.

If you're carrying a passenger then maybe 37psi front and 38psi rear.

42psi is the maximum rated pressure for most moto tires and only really recommended if/when you're asking the tires to carry their maximum rated weight loads. Recommend near max pressures for heavy +700 pound touring bikes; BMW K1200, Honda ST1300, Kawasaki Concours, etc but not for a 400 pound middle weight bike.

Whoa, a bit presumptious don't you think? Chill out, nobody's jumping on your "merits" just cause we got curious about the tire pressures.

Thanks for the review! I have been waiting to hear something about them...

*Dave R6 - I run my tires at 30psi and am not a squid in the hills or anywhere else really. Been riding at the track for a few years now and have been riding for more or less 20+ years as well.

Higher tire pressures equal colder tires and a smaller contact patch. If that's what you're after, why did you bother getting performance tires?

F*king Aye!!! Why do you all critiscize the guy???

If it works for him then let him run what he wants.

You all trying to act like a bunch of smart-asses.

Thanks for the review.....I'm trying to decide the next best tire for myself and this helped.

Uh no.

We were asking why he chose those tire pressures. Since when did curiousity become criticism?

The tire pressures....

Threadjack. Supertireguy, what street pressures would you recommend for Dunlop Qualifiers on a 1000RR used mostly for sport riding? I haven't run street tires in a while and don't have a clue as to the right pressures for these tires. The dealer gave me the bike at max pressure and I dropped them to 30/30 like my 208GPs, but I'm thinking that might be a little low for street use. I could care less about tire life. Max grip is my goal.

this thread has too much kawk.....

What do tire pressures have to do with the type of rider you are?

WTF are you talking about?

He's running the wrong tire pressures. That's not criticism. The irony of it is beautiful don't you think? He starts a thread reviewing a tire but doesn't know what tire pressures to run .. And who's trying to be a smartass? All i see is people trying to help the guy get the most out of his tires. More heat and more contact patch..what about this don't you understand.

Why am i even questioning you? You're gonna make a tire choice based on the above review... whatever

And if you run 40psi on the rear, wouldn't running that hard make a ride more uncomfortable which is one of the reasons you criticized the Michelin's? It comes to a question of safety too. If you saw someone riding around with cords showing on their tires, you'd say "hey, get your tires changed", that's not criticism, that's being safe. Riding on 40psi is UNSAFE versus a lower pressure. Your tire will not have as much of a contact surface, and not flex as much to bumps in the road causing your rear tire to chatter, again less contact with the road, again unsafe.

I know people who have ridden 20 years and they have bad riding habits. Just because you ride a long time doesn't mean what you do is right.

Agreed. I think it's legit to talk about tire pressure in this thread seeing as a ride review of tires is greatly affected by the pressure they're at.

 

[gsxrguy11]

Per Pirelli's website he is running within the recommend pressure. They recommend anywhere between 36 to 42 in the rear. I personally run my at about 36-37.

As far as the tire goes i have the tire as well and i am very impressed with it. It has good grip when it is cold and for me is a very confidence inspiring tire. I have not had a chance yet to test it in the hills but in the city they have been great.
