I'm sorry but the Diablo front tire is a very stable tire, especially in the corners where it counts, less side groves and special water dispersion pattern makes it more sure footed in the wet stuff. Yes it turns into the corners more easily because of the shorter sidewall, however, most folks tend to enjoy that, and its turning contact patch is larger, a positive.
LOL - I've been reading on tires again, waiting on Michelin to step up with their modern tire multiple compounds for us, but also in that reading I found out why Pirelli recommends the Diablo to be ridden as a set. The front tire is especially made to clear water from the rear tires path/footprint. The tread design is for water clearance and no more. The rear tread design is to move water more to the side - with no groves near the middle because the front tire did its job, and with the least amount of grooves it can have going to the side (tread grooves causing flex), and this tire also holds their latest belt technology. In tandem the tires become more than their separate identities, and really superior handling is the result.

+1 to EZ. Great handling on the Diablos. It doesn't drop into turns. It rolls into a turn, then a little more, or a little less, just whatever you want it to do. |

It drops....and that can be a little unnerving to those that arent used to it. But those that are experienced find they drop to a point and hold it there for some very stable cornering.
Once again the point I make is missed 
I give an honest assessment of the two tires. If you want strictly something for the twisties, then the shorter, smaller front Diablo is probably for you.
If you want something for mostly highway use, the taller (or any taller tire) MT75 is your probably your better bet.
The Diablo is twitchy when compared to the MT75. I never said the Diablo was unstable, but is less stable than the MT75 in a straight line.
The Diablo front does give an excellent ride, even better than the MT75. The 'oversized' Diablo rear gives a harsher ride than the stock sized MT75 (but that might be said for any oversized rear tire).
I also never said the Diablo's were bad. They are different. Just as the Kenda's, Avons, Dunlops, etc. are all different (though some are bad). If you're going to actually bother to choose tires for a particular style of riding, then you should make an informed decision.
FWIW: I would go with the biggest front tire you can find if you do a lot of 'dirt' riding with a Blast. The small Blast front tire does not work well on the loose stuff (yes, some people actually live and ride on dirt roads).
FWIW2: Lest it be found that anybody might actually want to race on a set of Diablo's. They are not rated for the extended high speeds (and heat) a Blast might attain on a racetrack. Tire manufacturers tend to leave a wide margin of error on tire ratings though. But the "scooter" label and 92mph rating on the tire might leave some (including track officials), squeamish. |

What's the difference between dropping into a turn and leaning into a turn? Does it mean that it just takes less pressure to lean into a turn? I like the MY75's. They seem quite stable. I also don't mind trying something new. Would the Diablo make the bike more nimble? I could almost see that as being an advantage.
So let me get this straight.... MT75 for a less nimble tire (ie likes to maintain a straight line) or the Diablo for more nimble, bigger contact turning patch...
Im planning on going with the ST66 for the rear, but the front has got me thinking....
Thanks for everybody's input!!! |

Concur - I totally agree with Erik! He has the right of it, true, a 'p' rating for a a scooter way heavier means just a great well built tire for a Blast - especially a lightened Blast.

So I’m curious which front tire is “Stickiest” when it counts, like in cornering? The MT75 or the Diablo? Which tire would be the safest? I assume a stickier tire is a safer tire. Everybody’s input is always appreciated!

I know I dont have an answer for that. I'd say its close between the two and without changing wheel size, they are both top picks for 'stickyness'. They're just different.
Tires are a lot about confidence. You can have the best tire in the world, but if you dont have any confidence (or maybe experience) in it, then its not doing you any good. You'll "back off" too soon anyway.
You can have the worst tire in the world, but if somebody convinces you its the best, you'll plow into every turn like you're on rails.
That's all just my opinion. |

Hey guys I…..FUBAR’d today..
Okay so here is what happened..
I just got my Pirelli ST66 in the mail earlier this week. I got off work today and felt like getting my new rear tire on my bike. My buddy that was going to help me bailed, so being the hard headed person I am, I decided I would put the new tire on myself..
I got the old MT75 off no problem, and started putting the ST66 on. I got one side of the tire on. I started putting the other side of the tire on… and let me just say. I have put some tires on rims in my day but this thing was the biggest pain in the ass (pardon my French) that I have ever worked with. Being by myself didn’t help either.
….So being the cheap ass or…resourceful person I am I decided to put the tire on using 3 screwdrivers I had in my garage (heck, it worked fine for the MT75’s)…
Sure enough as I was putting the tire on I nicked the steal belt in the bead of the tire. I pulled the screwdriver out of the tire and was sickened to see a 1.5cm chunk of rubber taken out of the inner bead of the tire with a little glimmer of steel belt at the bottom.
 
I thought to myself this tire will never hold air now… I finished putting the tire and as I forced the last part of the bead over the rim I heard a strange popping noise. It sounded like it came from that belt.
I aired up the tire and the bead did not “pop” as usual but instead sort of slid over the rim. Amazingly enough the tire held air and I checked the bead with some soapy water and found no leaks.
So here is my question… If the tire holds air is it safe to ride with that little bit of steel exposed in the bead?
Has the safety of my tire been compromised?
I wont hesitate on buying a new tire if its unsafe.
I’m going to sleep on it… I always value other thumpers inputs.
So what do you think guys? Thank you in advance! |

If it holds air and doesnt wobble when spinning (I dont know how much rubber you took off), I wouldnt worry about it.
I would balance it though regardless. |

Thanks Erik! I agree. After sleeping on it last night I think i'm going to ride it for a bit and feel it out. I spoke to some guys at work and they sure got a kick out of my story. A couple of them had actually told me some stories that were similar to mine, and they had no problems. Thanks for your input man! Its always appreciated. |

That last bit of bead is always a beach. Next time try folding the opposite side(the side that is already in the rim) into the rim a bit by putting pressure on the side you are working on and moving the outside of the tread into the rim. I think when you do that it gets the bead into the dropped center portion of the wheel a little better. The other thing is to use the tye wrap trick where you tye wrap the beads together to keep them together. The last time I tried that the tire when on the rim without the usual struggle. |

Thanks Swampy.Is a tye wrap like a zip tie? What is a tye wrap? How do you perform this procedure? Thank you to all thats responded!! |

Yes, zip tie. You just use the zip tie to 'clamp' the tire beads of the tire together so they cant seat on the opposite side of the rim you are working on (or seat anywhere on the rim).
A novel idea. I wonder if it would work on the big 16" tires? |

Dont worry about the speed rating unless you have a habit of doing 90+mph for hours at a time! (or are racing). |

Alright, well its going to be a minute before I replace the rear tire. Actually now that I think about it I probaly should just replace the rear dunflop at the same time huh? From what I've read I should do the 140/70 with the 110/70 which I've aready ordered. Concur? I will do 90 on and off for about 1.5 hours. I don't know how often that will be now that I've moved... |

Hey everybody, i'm purchasing my first set of tires for my blast and having one hell of a time. The only Pirelli Diablo 140/70-16 tires i can find that fit the blast are technically scooter tires. Are these the right ones? |

Yes, scooter tires. Correct. You'll be fine. |

I cut a shinko tire for a bike once, it was fine, I was using long tire irons too, that tire just seemed like it was too hard. Maybe sit em in the sun soften up that rubber, or it was just what it was a cheap tire. |
