RIMS TIRES...heeeeeeelp!

[octane]

OK folks; here's the deal

I planning on (as my next-next project) turning that
76 GL that I have standing there in the corner of my workshop
into a 'Bobber'.
Saw a pair of 16" rim GL1000 wheels on ebay...just had to have them.
Here they are:

They are in fine shape, and I'm sure they'll look brillinant on my bobber. Nice and fat.

On the rims it says:
Rear: AKRONT 16"-3'50-D-40-583-DOT
Front:AKRONT 16"-3'50-D-40-184-DOT

OK I get the diameter and width, the "DOT" is the Department of Transportation certification..what does the rest mean?
Is the 583/184 the month/year of manufacture?
as in 5 month of 1983


They are wearing "5.00s16" tires.

I've been looking at some new tires. They are marked:

Rear: MT90-16/74 H
Front: MT90-16/73 H

...argh, theres too many different tire classification systems.
MT90 is the Alpha designation for what in metric is 130/90,
meaning the tire is 130mm wide and (90% of 130=) 11,7 mm high
, witch again in Inches are called a "5.00/5.10 tire"

...am I right so far?

the 74 and 73 is the load designation (827 lb. and 805 lb.)
and the H is speed rating. H = up to 130 mph / 210 km/h

but I don't see anything telling me if they'll fit my 3.5 inch rims ???
I mean the 130 mm (5.00/5.10 inch) is the width of the tyre at its widest...right...not where it mounts at the rim ?
...or not ???

HEEEEEEEEEEEEEEELP !

will they fit ?


Thanks

Cant help on all the sizes, confuses me to. One thing that might help though, when a lester 16" rear wheel is fitted to teh GL1000 models its a right pig to get the rear calpier on. The trick is to unbolt the disc fisrt. Makes it easier/possible.

Dang would I love those on my GL Octane , also sorry don't know about the tire sizes but my guess is what you are explaining . You would also need a wider set of triple trees for that GL 1000 to fit that front and exchange the 1000 swing arm he 1100 to fit the 16 " on the back .

A long time ago, a friend had a rear GL1000 rim laced to a front GL1000 hub. I seem to remember it worked well with the standard forks and brake set up on his GL1000 with side car.

Right on Dougal , I didn't know . I learned something else , Thanks Chum . Those would still look great on my ride . as I'm striving for the Harley FatBoy look .

here we go Octane..................

Tyrespeed ratings...

J Type 62.....100
N " 87.....140
P " 94.....150
S " 112.....180
H " 130.....210
V " 149.....240
Z " 149+.....240+

TYRES WITH 2.00,2.25&2.50 NOMINAL SECTION WIDTHS ARE RATED FOR 75 MPH.

METRIC DESIGNATION...ie 130/90-16 67H

The 130=section width(mm)
The 90= aspect ratio(%)
The 16= rim diameter(inches)
The 67=load rating
The H=speed rating..

INCH DESIGNATION......ie 5.00 H 16 4PR

AGAIN,5.00=section width(inches)
H=speed rating
16=rim diameter
4PR=casing strength......(ply rating)

ALPHABETICAL DESIGNATION.......ie M T 90-16-LOAD RANGE B

M.... denotes motorcycle code

T.... denotes tyre width code

90....denotes aspect ratio(90%)

16....denotes rim size(inches)

LOAD RANGE B....denotes tyre load range..


ASPECT RATIO = HEIGHT/WIDTH x 100

LOAD INDEX RATINGS...........(LI)

LI 20=176lbs

you should be able to put any 16" tyre on the rim,but the only factor would be the actual tyre width once fitted..
a measure across the swingarm should give you an indication of how wide you can afford to go without tyre rub...

Sorry its long-winded Octane,but hope this helps you out........

Hi guys,
thanks for all your input. Appriciated!

To be on the safe side before ordering
(the tires ships from Germany)
I'll call the place that sells these tires, straighten this out
and make sure I know what I'm doing.


I've done some measuring on the swingarm and forks.
From what I see, at least there is room for the tires that
are on the rims now...not much, but enough.

Thanks again
Octane

Looks great octane,

I put harley 16" rims on my '76 way back in '82 using stainless spokes from Buchanons(sp) in California. Its close, but they WILL FIT! I recomend using rims with the center mounted tire vale as the calipers may have to have a small ground in the "grooves" to clear a side mounted valve (did this at first). I also used a Harley style fiberglass fender I scrounged up that just cleared the tire and just barely fit the fork legs. This bike handled so much better. I also recomend using a rim that has the safety bead (groove?) that is found on the Harley rim. If you have a flat this will keep the tire bead on the rim and could well save your life (4 flats with stock rim, 2 with Harley rim). If you pull a sidecar, go to the Lester 16" on back as the Honda hub is too narrow to form a strong triangle to handle side stress and spokes will start popping.

[Zryder]

Thanks for the tips Goldtr6c , Thats something I would consider to put on my 82 GL . So are you saying that the GL hub could be matched to the harley rim with said spokes ? And where mite you get info on the length of spokes , and or how long that the spokes should be ? Thanks and Welcome again . ( Z )

[RebelRouser]

Hey Z;
I have done a 16in Goldwing Rear Hub to a Triumph 16in Crome Rolled Steel Outer Rim, things to look for in figuring out the fit, make sure they have the same amout of spokes, dose not matter the lacing directions, check the inner circumfrace of both outter rims, if the same they can be swapped out, use the GL hub and spokes and any rim that fits, I also cahnged out a Front 18in hub with a 21in wheel and spokes the count was the same used the Goldwing front hub and the wheels rim and spokes... If you choose to do any spoke changes/relaceing, or whatever do take plenty of pictures for reference...

Yes RR point taken and saved by printing . I am also wandering here , I really love the FatBoy look of a cruiser , Just a thought as to what it mite look like on a springer though ??? But I 'm thinking that I can stick to my stock front tire and rim it would look great with the inverted forks , thats another reason I am picing up the inverted fork ideaas well as them being the simpler to fabricate . So many ideas and what looks best with what eh ?? Thats where what we do to our rides on a personal note make it what we all are individuallizing our rides .

[RebelRouser]

Hey Z;
The Fat Boy look on tne Classic Springer Frontends, Minus the fender and you have what we call the Classic Bober Look, Too much front tire for me, I perfer the skinny tall look my self, but the Inverted with a Bober tire, Short Bars and Dogbones would look great as a front end, just gots to loose al the fringe... lol, By the way, question for you, Whats up with those forward foot rest on your bike? There Huge, re mindes me of the old automobile gas and break peddels... Well to each there own as you put it "Thats where what we do to our rides on a personal note make it what we all are individuallizing our rides (Zryder)"... Take 'er Easy

Those are the auto foot gas pedals , LOL that I cut out with a CNC machine . What I would like there is a spike type of foot rest to keep it smaller and clean looking , I'm just experimenting there . Accually those foot pedals on the bike don't look so huge , I have many here asking me where to get them as there are one of that I hade made . So if you think to much tire , I think I will stick to my stock tire width then . They are 18 "on the front .
