I read somewhere, I believe on another forum, that someone was running a 175/60-16 Goodyear Fuel Max on the rear. It's not a run flat, so I'm not so concerned about that specific tire as much as I'm curious about that size. Would running a narrower tire give the bike a more MT feel, while retaining the benefits of a RF car tire? The other thing I'm seeing is that tire would also be shorter, so maybe 175/70-16. That should correct the speedo and maintain stock height or close to it. What do you think?

A friend of mine is using that tire on his 1500 Wing and likes it. I have never used it so I can't comment on it.

I've been using a 175/60R16 for several years. In my opinion it 'feels' more like a mc tire in that I don't feel the sideways 'push' in the truck tracks at some intersections. My first CT was a 195/55 but was soon shown a 175/60 by a friend at a Darkside get-together. I'll NEVER have another mc tire on the rear of my GL1800.

I like the fact that it's a RF but has the handling more like a mc tire that the 195. Mileage is at least doubled of a mc tire also.

I will be giving that tire a try at some point in the future! I still have 4 SnowControl to wear out first. They will probably last me through next Fall. (y)

I like the weight of the tire and noticed it has an additional .32 of tread!!

You won't be disappointed.

The only downside to the smaller tire, is you give you some lean angle.


yeah, thinks for the reminder. I've noticed a slight difference between the P1 and the SnowControl. (y)

I hadn't thought about that point Murgie. Not being a peg-drager it hasn't been a concern. To me the pluses of being a RF-CT far outweighed that issue.

How large a reduction in lean angle do you think there would be?

Not sure how that could be measured? Probably what I will do is find a nice twisty road that I run a lot with one of my other tires and run it at the same speed with this 175 and see what happens? I would expect a little more peg scraping? But not sure how to determine the difference without going out and experiencing it?

According to TireRack
DUNLOP SP WINTER SPORT 3D DSST RUNONFLAT specs in these sizes ......
175/60R16 vs 195/55R16 (overall diameter 24.3 vs 24.4) and (revolutions per mile 862 vs 856)
Also 4 lbs less and 1/32 more tread depth with the 175/60R16

Hey Cruiser, I hope all is well in your world. How are the knees doing?
I'm curious what kind of mileage you're getting from the 175/60R16 tire that you've been using?

Making a couple of general measurements ( removing front tire/rear tire/peddle effect, scraping anything other than the peddle and taking slight liberties with the tape measure). We can turn this into a simple right angle equation. Using the highest preload my peddle scrapers are at 254mm and they are 560mm a part. So center line is 280. Half of 175 is 87.5, so edge of tire to point under peddle scraper is 280-87.5 or 192.5. Making a right angle we get the angle from tire to peddle as 53 degrees. Recalculating for 195 we get 54 degrees. Reapplying the 1 degree to the distance, tire to peddle, means approx 5mm, 1/4 inch of more lean.

A lot of rough calculation here but you get the idea.

Some other things to consider. 20mm (195-175) of 175mm is 11.5 meaning % of surface area or braking surface.
Also 175s are rated 86H (1168 lbs) while 195s are 87H (1201 lbs)

Pulling a trailer I'll take the added braking surface and load capacity.
