The 180 without a doubt turnes in way quicker but is more likely to wash out than a 190 in heavy turning due to less surface area on the road..
I thought you were never wrong?

The 190/50 has a larger contact patch when stood up, but because of its sharper profile, the 180/55 has greater contact area at full lean.

If you are doing more commuting than canyon carving the 190/50 is your best bet. If you spend motr time leaned over, then go with the 180/55.

Maybe beacuse the idea of putting a 200 on the rear tire is just lame unless you're just going to drag-race your bike? :dunno


Just do a search on "Tire Size" or something. Sheesh. Here's one for you (found in 10 seconds)

Uh, either I got punked, or I linked a video that I did not intend to. my bad.

I don't want to call myself an "expert", but I've been racing for a long time and I have done a lot of work with the R1. I currently run on 16.5" 205's which is the same rubber that is on AMA superbikes. They are great tires, but for an average bike and rider they would definitely suck. The are designed to handle SB power output, not street riding. A 200+ tire on the street is a bad choice unless you're a drag racer and running it nearly flat. You need to balance the turn rate of the tire with it's overall grip characteristics... with the R1 that's a 180-190 tire. Bigger isn't always better with rear tires.

This topic has been discussed many many times and always has the same outcome and thoughts. If its a street only bike and U dont have a lot of flip flop corners (1 side full lean to the other quickly) then the quicker turn in of the 180 isnt really giving you any advantage.. However... there is a bit less weight on a 180 which will put a bit more power to the wheel. (Easier wheelie and quicker acceleration) None the less if U R not on a track... there isnt any need for a quicker turn in.... Better set up on your bike with suspension can give you that. Get more rubber on the ground and go with the 190 in that case... A drop 1-3mm on the front end or a raise in the rear end will give you back that quicker turn in... For this I recommend talking with your tire dealer or local race shop to see what good starting point geometry set up is for the type of tire you choose.... If they dont know.. Move on.

As far as the comment said about a larger rubber on the ground with a 180/55... uhhh no. An R1 rim is a 6" rim and will only widen out a 180 tire and reduce the actual contact patch of a 180. On a 5.5" rim (Like an R6) it remains tall and keepts it maximum contact patch due to the triangular profile). So in all reality you have significantly less grip from a 180 on a 6" rim than a 190 and even less than a 180 on a 5.5" rim. If you can get a 190/55 in your selected brand, this seems to be a good middle road solution. U have a taller profile and a large contact patch when at full lean. I dont know what style or how aggressive of a rider you are but hopefully this helps you make a decision that will work well for you.

As far as a 200 yes it will fit on yoiur bike and on your stock rim. Some times you may need a slightly larger chain depending on the length you currently have as well as if you have enlarged the rear sprocket any.... Make sure you dont have the tire rubbing the swing arm when the bike accelerates... (Please test this on a stand before U ride it... It can be a very bad situation....)

On my Street R1 I currently have stock chain, down 1 front and up 2 in rear and a 190/60 Dunlop Race barely fits in there. I needed 1 link extra to make it not rub... If that helps. The 190/60 is a VERY tall tire and only comes in a race tire anyway. A 190/55 wont be as tall.... Ill be putting a Bridgie DOT race tire in a 190/55 on there after I burn this one up.......

I hope that helps you a bit..... Good luck in your choice.....

Why don't we solve this once and for all. If someone with a 190/50 rear and someone with a 180/55 rear in lets say pilot power each go out and cut a piece of paper to match the profile of the rear tire crown when mounted on the 5.5 rim. Then scan these in and we will overlay them on top of eachother. But sure to include a scale like a 1" mark on the paper.

This will only work if both people have the same brand and model tire and they are not excessively worn.

Any volunteers?

I would do it myself, but I run Supercorsas.

i couldn't make up my mind either so I got a few take-off sets of 190/60 dunlop 209's. Pay about $100 for a set, gummied up on the sides, but like new in the center.

Good contact patch, but what I really like is how much harder you have to ride to get to the side of the tires. With the 190/50 I was to the side of the tire last summer. This summer I'm riding even faster in the turns, but with the 190/60, I rarely get off the edge of the tire. Gives me alot of confidence n the 190/60 profile. The only time I was able to get the gummies off the edges was at the track.

190/55 gives you both!

Problem there is the R1 uses a 6" rim, not a 5.5".
