Will this fit a C-10?
« on: December 05, 2018, 07:32:16 pm »
I've been considering a lower profile Radial for the rear of my C-10.
 I've seen several reports of wobble after some mounted the few radials that are currently available.
Thought that maybe part of the problem is the profile of a C-10 rear tire.
   {150/80R-16}

Another rider claims that a 180/60R-16 fits ok.
I've never heard of a tire this size fitting a C-10.
Does anyone know if it will fit?

NOTE: I think this tire fits some of the Goldwing's so it's certainly able to support a Connie's weight.
          One of the brands in which I found this size, are sold as a Sport Touring Tire, but most are sold for Touring or Cruiser's..

Ride safe, Ted

I have run a tire meant for the Goldwing 1500. It gave lot of miles, 20,000 plus.
The down side it's a hard tire this compromises traction. It's also a taller tire
this effects acceleration. Would I recommend it, no. Traction is most important,
money you can always get more.

The tire Ted asked about, is NOT taller, it's smaller in o.d., significantly...
almost 1", so it equates to sitting 1/2" LOWER...
but, wider... aspect ratio makes a big difference...

I know its an automotive tire website, but comparable data fields are the same, when considering the differences and outcome..... based on tire measurements.







Mounting different aspect ratio tires requires a bit of research on the allowable bead width specified by the rim rating,

they don't go high width tho... sorry...

Ted,

I've never heard of a 180 on a C-10...could be possible, though.  I do know a 160/80-16 will fit with no modifications...GL1500 size...whether it be a radial...or, a bias ply tire...might be more tires to choose from... :-\

i would be most concerned with rim width compatibility followed by sidewall width fitting between swingarm, but why does everyone hate the stock size so much?

We don't hate the stock size.
Several have reported a increased wobble with the Radials that are currently available.
  (Not many are available anymore)
I suspect that a possible reason is the current radials are flexing due to the high sidewalls, heavy bike, tall windshields.
NOTE: I rode with a friend that had visible {scary} wobble when he came up behind a big truck.
          He went to a Bias ply tire and solved the wobble.
          I like the radials, and was offered this tire to try.
             Was told it would fit.
          So, I'm thinking I might give it a try...

Posted here to ask if it would fit.
ie; Has anyone ever had a 180/60R-16 on their bike?

Ride safe, Ted

PS: Thanks everyone for your input to my question. {Particularly MOB}
       MOB, the dimensions you supplied are what I had guessed.
              ie; Too wide for the rim and OD too small.
         But I had hoped the OD was closer to the correct OD than it turned out to be... {gloom}

But; being me, I have to ask questions.
    Is the rim width a requirement for safety, or is the rim width required to keep the {as designed} tire profile?
    If installed on a smaller rim than specified, wouldn't the profile become narrower/rounder and the OD taller?

Ride safe, Ted

PS: The tire I was offered is a Dunlop Elite 4.

without digging out my bike, which is covered with tons of stuff right now, all I can say is measure the clearance you have now, between the widest point on the 150/80 and the swingarm at the closer points, then assume you need s similar clearance a half inch closer to the axle, and measure there...  based on the tire width in the chart, if you feel comfy with adding width, jump on it..  :great:
I'd do the measurement if I could see my tire.... >:( >:( :))

I do like the concept tho, and a smaller diameter tire does in fact increase "acceleration" rate, kinda like a gear modification.. you loose a bit on the top end, but can accelerate using less H/P..
If I didn't have very low miles on COGZilla's tires, I'd even wanna try some experiments like that..

all in all, it comes down to the tire, on the rim... every tire has different sidewall characteristics; some are stiff, and due to the way the chords are laid, actually resist getting "larger in O/D, mounted on a narrow rim, and in fact, get even "squatier", some with soft sidewalls, and more resistance, may grow in diameter when mounted on a narrower than spec'd rim... difficult to say, they all differ when mounting them on a rim width below the "design factor" of the tire.

do some measuring, it may well be feasible, if you have the side clearance you need, at a point 1/2" to 3/4" closer to the axle between the arms, and can stick yer 'pinky finger in there... meh',  :great: :great:

Did a finger clearance test on my bike.    Can get all my fingers in …   
        "No", I don't want any snide comments about that description! :-X

Still some reservations about the 180/60R-16, so looked for other sizes that might fit.
Found a 180/70R-16, a 170/70R-16, and a 160/60R-16.

Hoping someone can give me the OD size and rim requirements for those..??

Ride safe, Ted

PS: The 180/60R-16 is a Dunlop Elite 4, with 500 miles on it. Was offered to me at 1/2 price, my current tire {Metezeler ME-888 150/80-16 Bias Ply} is not badly worn, and this is my spare Connie that I like to tinker with. 
So, this is not a must do. This is just one of those experiment's that I sometimes get myself into.

use that site I linked to...
https://www.tacomaworld.com/tirecalc?tires=150-80r16-180-60r16

you can plug in various tire sizes, and compare the dimensions, its a really nifty tool I stumbled upon last month, and it gives you all the data for comparing...

 :great: :great: :great: :great: :great: :great: :beerchug:

you spurred/jostled my dead braincells enough that I'm really curious about that 180/60 tire...
If in fact it does fit in the swingarm, it is a cool idea, and will lower the back end 1/2" nicely, without messing with lowering links... and, will make for a "quicker launching" bike to boot... win win in my book, as I don't have a "7th gear mod", and just want the fastest acceleration short of adding a flux capacitor, on my old bike... especially when I get done swapping in my Ninja Cams, and my "5th gear" mod output gears.

Used the info Jim and MOB supplied and calculated the various Radial sizes that are available.
          {180/60R-16, 180/70R-16, a 170/70R-1616 and a 160/60R-16}

The 170/70- 16 is very near the same diameter to the stock 150/80-16.
The 180/60- 16 is the next smallest diameter to the stock 150/80-16.

I think the Diameter of the wider tires will increase slightly when installed on the smaller/stock C-10 width rim.
If so; I suspect; the 170/70- 16 will be a slightly larger diameter than the 158/80-16.
                        the 180/60-16 will remain smaller.

Ride safe, Ted

as I noted, don't be so sure that putting the wider/low profile on that rim, will really make it's O.D. grow as much as you may think... I say this as the low profile tires side wall chording, and direction/construction, may be stiffer, to prevent it from really growing... this, combined with the tread windings, is where the resistive strength of the low aspect tires get their "damage prevention" strength to prevent rim damages when hitting holes and such, may surprise you when they are inflated to "normal/recommended" pressures... so yeah, you may make them "grow", but it will take more air pressure in them than the operational limits actually allow, in order to see the growth.

so it ain't really a cut and dried assumption that the tire will "grow" in diameter, on the narrower rim...
I say this from experience in putting excessively wider tires, with low aspect ratios, on other vehicles with stock rims, and only find them to "pooch out" further from the rim, while not really growing in diameter.

I agree with you. I don't think there will be much change, but there could be some.
  I wanted a different profile, but want the OD to remain slightly smaller than the 150/80.
  Based on that, my last note was not stated correctly. Will correct that..

{My apologies; I neglected to give you the numbers previously}
  180/70-16 Diameter is 25.92".    Larger than stock dia.
  150/80-16 Diameter is 25.45".    Stock dia
  170/70-16 Diameter is 25.37".    Slightly smaller than stock dia    {+.03% Dia increase = 25.45 Dia}
  180/60-16 Diameter is 24.50".    next step smaller than stock dia
  160/60-16 Diameter is 23.56".    Too much smaller than stock dia.

Ride safe, Ted

put the dog gone 180/60 on the rim, andd let me know... your killin' me with antici-pation...

I think it's a winner, and the aspect ratio, may really be a nice stiff tire, with a nice tread....
and still not be a "darkside" candidate...


get'r done dude.... :great: :great: :great: :great: :great:

That's the plan. Waiting for the guy to reply.
Then; I have to spend $100 without "the Boss" catchin' me...
                                :67:

Ride safe, Ted

Update; The tire I was planning to use, has been sold already.
             Would have been cheap e'nuff to do the test...
              So, I guess it's back to the drawing board.

Still asking. Has anyone reading this "ever had a 180/60R-16 on their bike, or know of anyone else?
