Widest tyre on 3 inch rear rim [Archive]

Hi all!
Time for another silly question of the day that I haven't been able to get a straight answer from the dealer.. or anyone..
I am looking into modding rear end of my bike and wanted to first establish what size would be the widest tyre my 3 inch rear rim will take.

Currently it has factory 150 tyre installed.

Thank you look forward to your experience and knowledge.

For a normal tyre on a 3" rim 110 is the go. A 120 will go on but will be misshapen and handle worse. There are some exception tyres with stepped beads to allow wider but these aren't common at least on tyres for proper motorbikes.
Size of rim will be on the rim somewhere.

What's the bike?

A 180 tyre generally uses a 5.5 inch rim, front 3.5 rim a 120.

So your 150 on a 3 inch strikes me as oversize.

As above the actual rim size will be stamped on the wheel.

Good grief, just googled rim sizes. It' a 4.5". I wouldn't recommend you proceed further if you can't get a grip on the basics. This shit can be dangerous.

Ahh ok so special tyre type.
If you lace on a bigger rim, if spoked, or mag wheel you can fit a bigger tyre. If you have clearance, both to chain to outer of tyre and tyre to other components. The tyre may grow bigger in all directions but weirdo tyre on now will likely be high profile.
Be prepared to spend. It's easy to make something dangerous if you don' know what you're doing.

And you can really screw up the handling but that's probably not a design criteria.

Edit googled, read belt not chain, and spoked. But that rim looks bigger than a 3".

Thanks for the reply, yeah. I am consulting Harley themselves too. I am sure the stock rim is 3" according to HD booklet.. Have you googled pre-2017 streetbob? 2018 streetbob is completely new bike. Clearance to belt, rear fender etc seem ok, guess I will find out once the tyre is fitted.

If it's the same bike it says a 3 incher here.

http://www.syshd.com.au/motorcycles-2/2018-range/softail/street-bob/

And the photo looks like that rear tyre is on the rim tight.

Here's a thought - take a ruler and run it through the spokes and measure it with ya eyeball. The width is actually to the inside of the tyre beads so it should be a bit larger from outer edge to edge.

If it's 3 inch (which should be stamped on the rim as 3.00 x 16 ) then I'd be sticking to the stock tyre size unless you lace up a larger rim.

Rim has a stamp 16x 3.00 ......

I just had a brain fart though.
Ran a vernier caliper and measured a section end to end.. and it measures 4inch..
I'm confused.

the 3 in is where the tyre mounts on the rim so it would make sense the rim width is wider then where the tyre actually mounts

Pretty sure there is another way for a Harley rider to measure three inches ......... :sick:

So - three it is. And stick to the 150.

Or get a larger rim laced up being wearing of the previous clearance issues. Shit- it's a Harley they probably have a 5.5 inch genuine rim in the HD accessory book.

Flick through the HD specs heaps wear the 150 rear - I just presumed they would run something fatter now days for ego.

Hi all
I'm happy to report 180 / 70 -16 tyre successfully replaced my factory 150 / 80 -16 tyre on 3 inch wide rim. Same tube was used.
Note, ill be fabricating my own rear fender to suit.

now, on to my next triumph!

How many people do you need to tell you it's a fucking retarded idea before you start thinking that maybe it's a fucking retarded idea?

DODO``

9th March 2018, 12:36

Well at least you saved some money on a tube. Makes you wonder why they make different sizes when you can just over inflate them to take up the extra space.

Geez the pressure is the same, what possible problem can there be overstretched tube then load a 250kg bike at 100kmph and hit a decent pothole?

That all on a tyre distorted well past manufacturer recommendations.

This right here. This is why buying a vehicle that has been modified by a cretin is risky.

Yeah I'm through being nice. But sheesh dude this is in the same league as boy racers dropping their Mazdas onto the bumpstops.

But I'm sure you know better and will tell everyone no one else could give you the answer but you pushed ahead anyway.

Yeah nah mate, remember the tyre got wider but at the same time also gone lower profile, so we didnt end up over inflating it at all if any. I ended up having a long discussion regarding this with the manufacturers themselves (both harley and dunlop) every step of the way. pffft, dropping mazdas onto the bumpstops.... :facepalm:

When Harley fit a 180 tyre to their models it's on either a 5" or 5.5" rim.

Like I said, if you're suggesting that Harley have told you that fitting one on a 3" rim is fine, you're full of shit.

Hopefully your next WoF is due soon and they'll fail you. Or you'll get pulled over for something and the cop will notice that the rear tyre looks kind of weird.

5" seems to be the minimum width given by tyre manufacturers, although it looks like Harley mount it on a 4.5" rim on some bikes for that custom look.

Who fitted it? They could be in a shit load of trouble after the SCU examine your bike.

Honestly mate, this will not end well.

The only way that Harley and Dunlop would have said that what you've done is fine is if you're led them to believe the bike will only ever be a show bike and never ridden on the road.

Like I said though, I'm picking you're full of shit instead.

Though as per most of the urban potato tractors in Aus the center of the tire will be cut to the carcass in no time with completely fresh edges :rolleyes:

Now this has me interested.

i went to Dunlops tyre site and searched HD's appears they fit 150's to 3 inch rims 160 to 4-4.5

I tried to find your ride but it was not featured so I trolled some FFSXRFUCK HD model number (some of these are wild) and gave up searching for a 180. I was hoping to see the rim width recommended by Dunlop. I just don't know my HD models well enough.

I did find on one forum there was a HD 180 kit (up from a 160) that included the tyre and various brackets to move items further out to clear the fatter tyre. No record of rim width.

Go on - post the picture.
