Advantages of a 180/55 vs 190/55 tire.

I recently had a 2 inch screw in the rear tire (right in the center) of my bike and I decided to plug it(not leaking but I just don't feel safe with it). Recently I came across a real good deal on some Pirelli tires but, they are 180/55 and my bike currently has 190/55. I have been asking around and been told by some places it would give me a better lean angle since the 180/55 are more dome vs the 190's which are more flat. I went to cycle gear and lined up to of the exact same tires except for the size and I must admit that the 180's do look more dome than the 190's. I went to a few more places to ask and they told me that it won't give me a better lean angle but will help with the transition from center to lean much easier, but that I will be running on a smaller contact patch. My question is has any one ran these size tires and what are the advantages and disadvantages of both. Thanx

don't do it. the 190/55 is on your bike for a reason. with all the low end torque you have you'll blow a 180 right off the asphalt on a good turn as soon as you get on the throttle. turn in on the 190/55 is almost identical to the 180/55 so there really isn't a benefit whatsoever. talk to albert over at cycle gear and tell him donnell with the zx-10r sent you in, he'll give you a good deal on some pirelli's in a 190/55.

for the street....i think you'll be fine using 180 or 190's.

and if you compared a 180/55 to a 190/55 of the same tire brand and model.....you shouldn't really notice a difference. the 190 might look less round, it's only because it's a slight bit wider. it's an optical illusion . the transition from center to lean will be quicker with a 180, but not really extremely noticeable.

my bike comes stock with 180/55's...i run 190/55's on my 600rr racebike...only because i like knowing i have that extra bit of contact patch to work with.

if i was to ride the street again......180/190 doesn't matter...they both work well.

I have a 180 on the rear of my Hayabusa. 10MM shouldn't make a huge difference, but I noticed quicker turn in, less bar effort at lean, and no perceptible difference in grip. But, I only run 1:58's at MSRH, basically babying the rear so I don't highside my street bike on a corner exit.

Biggets difference, I think, will be less rubber when upright, which means more wear under power = less tire life to squared off.

But, so many have 180's on 17 / 17 rims it's not like you're going into unproven territory. Maybe a 190 is like 2% better. My money said go 180 and get quicker handling to boot.

you're comparing a 180/55 to a 190/50, which is a completely different shaped tire than a 190/55 that comes stock on the 1098. i'm telling you people...the 190/55's handle just as well as a 180/55 but you get more contact patch! there's a reason why every fast 600 rider/racer on the planet has switched to a 190/55, or even 195/55 and even 190/60.

Yup, didn't realize it was a 190/55 vs 180/55. That changes things. But it should still be OK, just not great. If it was my 1098, and I had a little bank, I'd prolly go with a proper set of tires.

Stay with the 190/55.

If you raced, and had a 180/55 and wanted to go to a 190/55 than depending on the bike I'd probably recommend it. However, at this time there aren't any bikes that come with the 190/55 on it that I would recommend going to a 180 on.

Keep the 190/55. The new Duc MotoGP Replica will have a 200 on it.

I am not a bargain hunter I just run accross them. I am not going to turn down a good deal just to go pay more just because I own a 1098. The only reason I got the base is because I didn't want red to many out there, didn't like how the black hides the lines plus its not an actual black, and the tricolor just doesn't seem worth the price.

Hi HD I went with a Pirelli Diablo Corsa 3 on my 1098, dual compound hoping to get a little more life out of it, very happy so far and I stuck with the 190/55/17, we need to get togather and ride sometimes, Tim

I would like that I have only seen one other 1098 (a red one) on the road but I was on the ambulance (working) when I saw it. Just let me know when you can ride. Yeah thats what I came accross some Pirelli Diablo Corsa 3 the dude had bought them brand new and was going to put them on his bike but wrecked a week before he could put them on so he had no use for them and was just looking to get rid of them. Couldn't pass the deal up so I got them but, I will probably sell the rear and get a 190 instead. I was just asking, this way I could get some info before I decided to put them on.

Haha thats awesome, yeah there is nothing like hearing that sound. I remember when I got my exhaust I almost fell asleep on my bike while it was running just listening to that beautiful sound or maybe it was just the build up of carbon monoxide lol
