My uneducated guess is that the 180 (due to its more rounded shape) takes more lean angle to get the edge. Am I correct in this? Anyone know the exact difference in lean angle degrees (ie, it takes 5 degrees more on a 180 vs. a 190 to get to the edge). My riding buddies and I had a conversation over some beers this weekend. Just curious. |

old racer trick: drop down a size and she turns quicker. |

Let me rephrase it: In order to get rid of one's chicken strips, who would have an easier time (ie, requires less lean angle) the guy with a 180 or the guy with a 190? |

I think the question depends on the width of the wheel the tire is mounted on. Given the correct wheel width, the profiles should be fairly similar, shouldn't they be? I would think the 190 would take just a hair more lean angle. |

On a 5.5" wheel, a 180 will generally take more lean angle to get to the edge, and will offer better turn in characteristics. Unless you have a lot of power to put down AND you're on a HP racetrack... I think the 180 is the better choice. |

who cares ? So you don't know either, eh? Believe it or not the 180 vs. 190 question is discussed on most sportbike forums...but thanks for your insightful comment. |

M1 sorry thats incorrect. The 190 is pinched a bit so its harder to get there with the 190. Had both and presently run a 190 and its harder. |

wouldn't a 190 have more surface area, thus making the lean angler greater to get to the edge of the tire? I NEED GRAPHICS. |

All I know is the wider the tire the crappier it handles. Remember the X1 came out with a 170. BARKER is 100% right if you want to storm the twisties drop a size. |

Cowboy your X1 also came with a 5 inch wheel is why. I'm going to have to get into Pro racers fan mail and tell them all to drop a tire size. I wonder if their pit crew knows it'll make them faster?? Sorry Don't buy it. |

THis 180/170/190 thing confuses the hell outta me. Must have alot to do with the 55/60/70 designation after the 180- yadda shit. The reason I say this is the Dunlop 170/60 D205 Dunlop Sportmax I took off my M2 is a tad wider than a 180 MIchelin Pilot Road 2 I just installed. I have PM wheels, the back one is a 5.5 incher. The bike does turn quicker with the Michonary's...heh...anyhow, Im probably not helpin this disscusion at all....sigh |

I normally run a 170 tire since it turns in so much better...but I always have the strips...with the 180 I pretty much don't have a problem with getting rid of them... |

Given the same sized rim, a 190 will have a flatter center profile than a 180. The 190 will have sharper countours to the edge of the compared to the 180 as well. (this is due to the fact the belts in the tire will not allow it to change it's outermost circumference). The result is a 190 will have more surface area going straight and in mild leans, and turns-ins will be harder. But, the 190 will also have less surface area and an unstable feeling at extreme lean angles. If both the 180 and 190 are mounted on the correct-sized rim, they would feel the same with the 190 offering a slight advantage in surface area across the board. |

.I have more time on a bike seat than most here have breathing. Do you have any idea how that sounds.LOL I've been riding 22 years now..... Soooooo what. Theres guys on this board that ride circles around me and they might have been riding 5 years. Your experience in the seat has no credibility on this subject for that matter. |

drop to a 170 for quicker turn in. to get rid of chicken strips, that's more about riding style and faith in your tires.

"I'm going to have to get into Pro racers fan mail and tell them all to drop a tire size. I wonder if their pit crew knows it'll make them faster?? Sorry Don't buy it." I thought it was common knowledge. |

You guys might want to go talk to the factory teams then and tell them to drop to 5 inch wheel's with 170's and cash in there 6 inch wheels and 190's because its slowing them down. Cowboy, Where did I insult you??? Your riding experience has nothing to do with this discussion.... sorry. |

turns in quicker. but leaves less rubber to drive out on under the massive power or hold on the big sweepers, especially on the big liter bikes. I never said it made faster lap times, just that it turns in quicker(easier) |

I do not know for sure. But looking at pictures of bikes with 190's vs the 180 on my bike. I would say that Yes, if you put a 190 tire on your buell it will be easier to ride all the way to the edge, thus eliminating your chicken strips |

It's all about riding style. If you want to be rid of the "chicken strips" just go for a ride in the twisties, and don't hang off the bike. |

Aswome picture Barker, I have it over my desk, with the caption "Faith: Because chicken strips are for loosers". It was posted here somewhere. But admiring that picture and looking closely... It looks like Faith ain't enough. Look very closely at the rear wheel, shadows, and rear wheel axis. Perhaps the caption should be "Gear. For when Faith exceeds physics". |

I have tried both. If your talking on your Buell with the 5.5 inch rim, then the 190 would have to lean further, BUT THE PROBLEM is, I think you would actually ground the hard parts before you got to the edge. Riding on a 180 with knee, ankle and toes on the ground, I was at the edge. Same exact curve, same exact contact points, but the 190 still had 1/4" chicken strips. It was really interesting to see that the front tire with the 190 had the same exact lines, whereas with the 180, the front was a tad bit wider than the rear. Both sizes were with the Continental Road Attacks. |

The 190 will have bigger chicken strips. |

Just brainstorming here - but after looking at my X1 (wearing a 180 now - swapping to 170 within the week) If you put a wider tire on the same size wheel, the tire beads on both sizes of tire will be squeezed to the same points - thus the treaded portion of the wider tire will be sharper at the edges. (less contact patch while leaning) It also makes sense that the "chicken strip" portion of the tread will be at a sharper angle, so will require more lean angle to reach. $0.02 (Message edited by pkforbes87 on August 22, 2008) |
