Can't find 155 80 R12 sidecar tire

Several available in Western Australia....

Yep I know... not helpful.

But there should be some on your side of the pond.

Miles will chime soon in about what will fit your wing 

Is it one more post and youcan show us some pictures off your rig?

Maybe share a bit about here you are and are at.

Welcome.

Looking for a good 155 80 R12 sidecar tire. Also will a 205 55 16 fit in rear of 2018 goldwing tourer

Yes, the 205/55-16 will fit on the rear wheel,  and inside the rear wheelwell, of a 2018 Goldwing Tour.

I have that same size on my 2019 Goldwing,  in a Bridgestone Driveguard +, which is a Run Flat car tire.

On the 155/80R-12, there are 16 different brands and models of that tire available...online...or go to any Walmart and look in their automotive section for TRAILER tires.

My wife's Hannigan Classic sidecar uses that same tire, so I know they are available. 

You could call Hannigan sidecar,  and ask Stephanie where they get their tires from. 

Robert I should have read the size more closely.  I bought two of that size from Amazon for my previous rig with a Hannigan Astro.  Cheap and easy to get mounted.  Free shipping was a plus.

I just sold a 1987 Chevrolet Sprint turbo, and got that size for it often off of ebay. Matter a fact 2 just a few months back. You will not find any high end name brands, but there are lots of them out there.

Thank you for the info gentleman. I found one from Giga tire in Cali. and should have by this weekend. I am also wondering what to run on the front also? Has a old Bridgestone pilot activ on now.

Thanks for the welcoming Brstr. Been member for a year but having trouble trying to renew membership online. Keeps telling me that my username and password is already used, no kidding, it's me.

My rig is a white 2018 Wing with Hannigan GTL from a past member. The car has a doggy door that previous owner had installed. Have not seen another with one. 

Robert, the tire on the front of your bike cannot be a Bridgestone "pilot activ", because the "pilot activ" is made by a different tire company...not Bridgestone.

The correct tire you want to install on the front wheel now is.... Bridgestone BT-46 rear motorcycle tire, mounted onto the front wheel backwards....and you want the 140/70-18.

Yes, the OEM tire size for the front tire is 130/70-18, but I can confirm that a Bridgestone BT-46 in a 140/70-18 fits perfectly inside that front fender.

Remember.... mount it backwards on the front wheel.

And Robert, the quiz question of the day, randomly selected by an anonymous viewer...

What air pressure are you going to be setting that new front tire at ?????????

What is 32-33lbs. up front Mr Miles, 

Let the pavement heat it to 35 and rides nice, hot days may get up to 38-39 and that puts out the tpm on dash. Hope i am correct and if so what's the prize !!!!

Sorry for my confusion on the front Michelin tire sir.

Got all tires ordered and hope to have on this weekend if all arrive on time.

Here is my rig and my other rides for your viewing pleasure

Robert, the Red Panhead is nice... really nice.

Before I give you the correct tire pressure for that new front tire, can you tell our viewing audience what mileage you are getting out of your front tires using that 32 - 33 psi ???

Well Mr Miles i have put 8,500 on the Michelin since I purchased the rig which had 18500 on the od. But the tire was replaced from stock and bike sat for sometime before I purchased. Found minor dry rot cracks on all tires and that's why replacing all. So don't know what I could have gotten out of it. 

Safe travels to you on your way to our lovely state of Pa. for the hootinany. Sorry I couldn't make this one.

Robert, understood.

How would you like to get 20,000+ miles out of the new Bridgestone BT-46 tire, mounted onto the front wheel backwards?

Short story: put that new tire at 40 psi, cold ...and always keep it at 40 psi, cold.

If you want the long story, and the WHY 40 psi, it will cost you one half of a Stroopwaffle.

Nice selection Robert. 

The Buell is as close to a Harley as I would like to get.

it would produce a huge grin factor. 

Oh my, the Pan...I had to download the pic so I could zoom in to better see the details. Outstanding.
