The difference in RPM for a given speed is not all that much more than what it was.
Just FYI, if the tire is heavier, there may be a decrease in fuel mileage. Probably not enough to worry about.
with my '02 1800, the mpg between tanks of fuel, with and without my trailer, did not vary enough to make it worthy of note.

the difference in weight for just the tire, is so miniscule as to be totally discounted.

the real world effects are directly related to Throttle use, and terrain, and Headwinds.

Throttle use includes trying to out run the Speed Limits....
In Oklahoma, we now have some roads with speed zones at 75 mph, and Texas has roads marked at 80 mph.

I personally am not patient enough to ride slow enough to get 40 mpg per tank of fuel.
average for me is in the 33 to 37 mpg range.

Probably. But rotating weight (tires) costs more than fixed weight (the frame, etc). Many years ago, I raced bicycles, and we figured that an ounce on the tire took as much work to move as two ounces on the frame.

WingAdmin makes valid points. IMHO- do what you want. Run what you like. My original point about tire manufacturers is that they will NOT say "sure put that car tire on your motorcycle"... their lawyers won't let that happen. the car tire is not designed for motorcycles- would you put motorcycle tires on your Accord? no.. not unless you did so to get home!

I have a trike.. YES I HAVE CAR TIRES ON THE REAR AXLE! Will I put one on the FRONT tire? probably not. But, logically, I could because the trike doesn't ride on the sides of the tires in a turn...It just never occurred to me to consider it- that's the motorcycle end of the bike,.

Correct. Unsprung weight (the part of the wheel/tire/brakes that is on the "road" side of the suspension) costs heavily in terms of efficiency, mileage, traction, and more.

Racing teams go to great expense to put extremely light magnesium wheels, lightweight tires and lightweight aluminum allow suspension members to get the unsprung weight down as much as possible. You'd be surprised just how little those giant wheels and tires weigh that you see on racing cars.

???

you mean that you put it on a 1500 bike, right?

175R16 is smaller than the stock 195R16 for a gl1800.

Hey everyone first time posting. On the subject of darkside tires. After much reading i decided to try it. Found this tire on Ebay. https://www.ebay.com/itm/263835509921. An Achilles Multivan 195/65/16 It has worked very well for for 10,000mi now Installed with the counter balance beads and no issues. Putting the Ride-On for motorcycles, balance bead with sealant in the front tire this year to see what happens. It's a D rated tire so to make it a little skinnier and give it a round profile i run it at 60 psi with out an issue. I also pull a little trailer at highway speeds and don't even know its there. Had to deflate it completely to get it between the swing arm; but it will fit. Inflated and checked clearance all is well. Great tire at a great price, will order this tire again. Looking for my pics to upload later.

It does NOT rub the swing arm, it does NOT ride on the sidewall. This tire works well for me, I like to toss it around in the twisties here in the mountains of British Columbia. 8-)
Has anyone else used this size tire?
Just trying to get followup with original
poster who hasnt been on this site for a while
or at least hasnt checked his PMs.
My bike is an 89 and my concern is, are there any
changes to the swingarm from my 89 to his 97 1500.

I think you may have found the perfect tire for the 1500 based on overall tire height in order to retain as close to factory tire size/height. if this tire clears frame/driveshaft and under fender. I am buying one tomorrow for my 99 1500. Thanks for posting and i look forward to your response regarding the aforementioned.

Yes flyingdragracer I searched long and hard to find a tire as close to factory as i could. When I found this tire I thought, what the hell it was cheap enough to try. After running it for a couple of months, pulled the bags to recheck clearance. all was well. Been running it for about 10000 miles and very little wear. Did have to use the "helping hand" on my brothers tire machine to seat upper bead. Thats the roller used to push down on the bead so the installer arm can push the tire under the rim. Tire is very stiff. Also did have to completely deflate the tire to squeeze it between the swing arm. Then because its a "D" rated tire, I started to inflate until the tire started to curve and lift the bike. Checked the pressure it was only at about 35psi. Inflated to 60psi to give it a nice profile and to narrow it up a little. Works great, would recommend to anyone going to the "Darkside". Still looking for the pics.

Have a safe riding season everyone.

Thanks trailrated so with that stiffer sidewall of a D rated tire and 60PSI did the ride get harder or any negatives after 10000 miles. Thanks again

Only thing I really noticed is the bike has a tendency of returning to neutral upright just by relaxing your push in to the corner. And have taken twistys deep enough to scrape pegs without issue. Totally predictable and manageable.

I'd be interested to see how squared off the corners of the tire are when mounted and inflated. It does look like a good alternative!

I ordered one today via ebay https://www.ebay.com/itm/263835509921 as TrailRated had posted. I should have it in a few days and will have it mounted in a couple weeks after that. I will post some pictures and opinions as well. Thanks again to TrailRated for posting the info.

Being that this is a car tire or truck tire I should say, is it uni-directional?
Most motorcycle tires or at least all the ones I've ever seen are directional meaning you can only mount it one way for one spin direction.

Good question, my guess would be no.
Appears to be a basic older style, of tubeless tire, to me.

And also why class D? Is C not enough?

I was briefly reading in the valkyries forum and somebody was trying the same tire 2 years ago.

Its not that a C class isnt enough. The issue is this is whats available and a D class simply offers more security with even less chance of tire blow out due to overloading the tire. Overloading the "motorcycle" that is another story altogether.

That is my point triwing. A C class tire will support much more than the GVW of the bike. Thats why I said it isnt that a c class isnt enough its the fact that the D class is available and it matches the original tire diameter nearly perfectly

Don't class D tires also have stiffer sidewalls?
While not as stiff as a run flat, I would think a class D tire would offer a little better control if a tire failure/flat occurred. Not something to ride on for 50 miles like a runflat could by any means, but may help with a blow out.

This is another tire to add to my list of possibilities for darkside.

I am still leaning to a Taxi tire due to actually being taller (I would welcome the slightly lower rpm's at highway speed).

All of the Taxi tires I have seen are actually smaller than the original equipment tire. Which is one of the reasons I liked the Multivan tire it is almost exact to the original equipment tire diameter. there should be no change in highway RPM or any losses of torque.

Thanx for all the interest in my tire find, and also for the mention in the newsletter. Pulled the bags again after reading all the responses. Still no rubbing. Even increasing pressure to 65 psi to get more profile. Riding 2 up and towing a trailer, still no issues, running the stock set of shocks even. Also just changed the front tire to the Shinko 777, very nice tire, lots of water dispersing grooves, perfect for the rainforest weather we have here in the PNW. As far as the sidewall, yes very stiff. Could very well act as a run flat, although I did not check it deflated and with weight on it for clearance. Maybe the next person to install could check that. I myself am now curious about it. Well folks off to my ABATE of Washington meeting. Then for a ride.

Be safe everyone, happy riding.
