Unless you are doing it knowingly to affect geometry, etc, there is no point. At all. Unless you already understand what it will help and what it will hurt, don't do it.

Re: 190-55-17

The 190/55 was made for the 5.5 inch wheel or 6 inch wheel. The Tire spec books list it as a recommended size for those wheels. A mechanic who says anything different is an idiot and shouldnt be touching bikes. He obviously isnt keeping up with current product applications. The 190/50 is not specified for the 5.5 inch wheel and shouldnt be mounted on a 600/750. Not to mention that the 190/50 is the most worthless tire profile ever invented unless you ride slab 24/7.

It will change the geometry of the bike. The brand of tire will also change the actual size of the tire. The Bridgestone S20 in a 190/55 is taller than a Dunlop or Michelin. The change in geometry will make the bike steer faster.

We went to the 190/55 in 2006 or so and havent looked back. Much better profile and the bikes handle much better. I dont like to put them on R6's because they eat power and the R6 steers quickly enough but on anything else it's a huge improvement.

Having chicken strips after a trackday with a 190/55 is really nice. Knowing that there was a little tire to spare is really good for confidence.

Is this a race bike or a street bike?

It depends on whose 190/55 you are installing. Some tire brands make 190/55's that are meant to go on 5.5 rims. Other manufacturers 190/55's are meant for 6.0 rims.

I good rule of thumb, if the particular tire you are looking at has a 180/55 tire size available for it, then the 190/55 size is probably meant for the 6.0 rim. For example, Dunlop race tires don't come smaller than 190/55 which is meant for 6.0 rims. However, Dunlop street tires (Q2) is made in a 180/55 size.


Since you didn't mentioned the kind of tire you are using OR what you are using it for....if you are just putt-putting around on the street it won't make a damn bit of difference what kind of tire you are using, so don't pre-occupy yourself with "benefits" if that's all you are using the bike for, not to mention that a 190/55 tire has more rubber and is heavier in weight than a comparable 180/55. These things are more of a consideration if you are taking the bike to the racetrack. If this is just a street bike then just make sure the tires are black and round and you'll be fine.

Re: 190-55-17

You will be fine.

I have ran a 190/55 from Bridgestone, Michelin, Dunlop, Pirelli and even Continental on a 5.5" rim. I have even ran a 200/55 from Dunlop and Michelin on a 5.5" rim.

Based upon this thread, you likely won't notice a difference.

Re: 190-55-17

I had my friends install 180/55 Q2 on their 600's with 5.5 rear rim. Pretty sure the 190/55 Q2 is meant for a 6.0 rim and the 180/55 for the 5.5.

If you were using Dunlop race rubber the 190/55 if meant for the 5.5 rim and 200/55 for 6.0

Re: 190-55-17

I'm not sure of any 190/55 street tires that are designed for 5.5 rims. Like I said, if the tire you are looking at has a 180/55 option, that's normally what is intended for it. Don't forget, a 190/55 is more rubber so it weighs more as well. If you really are planning to take it to the track then I would say stick with the proper tire size for you application.

Re: 190-55-17

I'd say, the only difference you will notice if you go with a 190/55 on the street is a bit sharper/faster handling if any.
I have only started noticing differences in tires during track days. Not much, if any on the street.

All of the 190/55's are listed for 5.5 inch wheels. On a 5.5 inch wheel the 190/55 offers you a larger contact patch at lean and more lean angle before you run out of tire compared to the 180.

To the OP... look hard at the Bridgestone S20 first. I have beat the piss out of them at the track and on the street the tires are flat out amazing.

This is me on the #69 with a 190/55 and the tire has about a 1/8 inch chickenstrip after the race weekends. I'll take that over washing out a 180 any day.
