Advice on Rear Tire Selection

I want to consider going to the 180 rear, like my Ducatii, for my Ninja ZX-10R. The Ninja has a stock 190 rear. Would I loose traction out of turns with the 180, or just love the bike more?

this is the 4th thread (on a couple bike sites), that riders want to go DOWN to a 180 rear from a 190 stock. WHY, WHY, WHY, would you want t do that?????? its like haveing a kick ass modded bike with full exhaust, race filters, bigger intake, power commander and a custom map. then one day deciding F' it, im gonna bring my bike back to boring ass stock and ride it that way. kinda boring and plain in my book.

STEP up to a 190/55 rear tire. please, just do it. you will thank me for it. turn in is effortlessly acheived. i didnt have any issues before, but now its like a whole nother bike in the twisties.

step up to a 190/55 rear. i assure you, that you will not regret it.

i run a 190/55 on the street and the track.

I would guess that the duc has a 5.5 inch rim (unless it's a 1080) and a 180/55 tire. Is the rim on the kowee a 6 or a 5.5 and if it is a six is the tire a 190/50 or 55?

I had a Aprilia with a six inch rim and it came with a 180/55 but in the user manual it gave as tire recommendations for the bike as 190/50 and a 180/55 which are very similar tires. The 190/55 is recommended for a six inch rim and will have a similar profile as a 180/55 on a 5.5 inch rim.

Now the 190/50 and the 180/55 are very similar tires on a 5.5 inch rim, go with the 180 because the tire cost is less. If it is a six inch rim pay the money and get the 190/55 because with the 180 I think the profile is to flat causing problems in the corners (slower or harder to turn in). That's my

I tried the 180/55 several times on my zx10. The turn in is much easier, and there isnt anymore problems with traction than there are normally. However they wear out very, very quickly.

A 55 profile works very well for handling. That being said, if you can get a 190/55 I would do so. I am stilll working on a stack of tires that are 180/55 and plan to go 190/55 as soon as I am done with my tires.

I would not use a 190/50 again. I like the faster turn in on the 55 profile. But like Vash said, I don't get much life out of the 180/55 on the track.

Vash: Did you get confirmed for VIR for March 24 and 25? Sorry I haven't been posting here much. Had a Jennings GP date and a lot of work to get ready for it.

yup, i run a 190/55 here on the street and the track. i would never think to go back to a 50 series rear. turn in on the 55 is so much better.

I am going to go out on a limb here and say the guy has a 5.5" rim and a 190/55 tire is going to be more tire than he needs.

You guys with a 1000cc bikes and six inch rims may think you need a tire like the 190/55 but that tire on a 5.5" rim is going to feel like you're falling of a cliff.

If he has a 6" rim disregard this post.

He's talking about a ZX-10R. 190/50 is stock, and a better replacement would be a 55 series tire. 190 if he needs the additional contact area for sure.

What year is this bike, and what size rear rim does it have? The 06's, 07's and 08 come with a 190/55 tire. I googled the ZX-10R and can't find 04 and 05.

It's somewhere around a 04 to 08. And they have all had 6 inch rims. Unless he has changed the rims.
