Well, I wanted a 145 X 80 X 15 michlin but couldn't find one, so I ended up with a 155 X 80 X 15
BF Goodrich.
Getting the rear wheel out from under the 09 750 Aero was a trial itself, but then things went at the normal profanity laced pace.
I have three of JC Whitneys long tire irons and one of their portable bead breakers so I went to work.
First break the bead.
Then slip the three irons into the starting position and pull one over to start. Tie the iron down so it cannot slap me silly when I have both hands on the other irons. You all know the feeling.
Then walk the other two irons around the rim.
After removing the tube, pry the other bead off the rim.
Lube with liquid soap and a tiny mix of water and iron the first bead onto the rim.
Bloody knockles getting the valve stem into place and push the tube into the tire, (add a small bit of air so it will not have a fold.
Iron the second bead onto the rim, This went so easy and quick I forgot to pick up the camera.
Spend the next two hours amid profanity and appeals to motorcycle gods etc. trying to get the dark side tire to take a proper bead set. Lots of lube and repititious airing and deflatings until sucessful.
Aren't you glad you didn't wear your good riding clothes for this job?

How many pounds of pressure did it take to get it to seat, I'm guessing around a 100 psi, metric rims are a little bit bigger than the ID of a 15" tire, 16" are fine but there a LOT of controversy about 15's on how well they handle the stretching of the bead.

When I was doing michlins 135 X 80 X 15 I generaly got them to seat between 65 and 80 lb.
This BF Goodrich took about 75 for one bead and 90 for the other. They do get a little scary.
It seems to depend on the quality of the rubber. One of my friends tried a cheap 50 dollar tire and it exploded at about 70 lb.
Lots of very slick lube, I have even tried KY jelly.

that is the same tire I run on my suzi,..I have 25 000 kms( 18 000 miles) on it and it still looks new, beaded up with little effort, and no issues with hack or solo riding, ..not bad for a $69.00 tire eh? hehe good luck, crawf.

You are referring to the BF Goodrich?
Phelonius
yes phel, a 155/60/15 BFG is on mine,..I have a factory aluminum center-line type mag wheel tho, without a tube, my only findings were to lessen air pressure to 12-14 psi while solo, ( no car) or 18-20 psi with wife, child ,hack and tools,..I found the auto sidewall very unforgiving at auto recommended 35psi I also use tire inflation to assist with camber setting of lean to or away from the sidecar,..I am very very pleased with the BFG, and the 155/60'13 on my CF1 car,..unit handles like a dream,. 2 fingers on the right bar at highway speeds .good luck, crawf.
also, with the alum wheel,..I knocked out the bearings and the local tire shop that supplied the tire installed it,..center was too smal to fit usual balancer, so the ol' bloke from the counter had to balance it old school on the manual bubble dancer , works great with no hop,..crawf.
Made a shopping trip to Kona yesterday, 115 miles. 2.75 gallons strong head winds on the way south, side winds going back north. Speeds were 60 to 65 most of the way.
So milage is just the same as before, possibly an edge better.
Tire handled very well

65 MPH speed limit on the Big Island now?

65 MPH speed limit on the Big Island now?
NO definitely not, but that is the average speed of traffic along that stretch of road. I held about 100 yards behind the next vehicle in front. A few passed me and the rest, but I can't afford the tickets so I just rode along with everyone else.
It is the long straight stretch through the black lava desert between Kona and Kwaihae. North of Kwaihae, 55 to 60.

A new note here. The BF Goodrich tire failed after only two weeks in service. Damage seems to be the over pressurization to seat the bead weakened the sidewalls.

Congratulations,,,,that's a LOT of work, don't forget to take the weights off, do y;ou have a way to balance your tires?
Ted
Have no way to balance the tires. Did not take the weights off but was sure to line up the factory mark with the valve.
I am hoping that the weights were mostly to do the rim.
Tomorrow I will hit the road over the Kohala mountain pass and find out if anything is badly out of balance. Later a high speed run to Kona on friday.

No one locally was able to balance the rear 14" wheel with auto tire on our K100 rig. So I tried some Dyna Beads and it effectively removed the out-of-balance shakes, even tho the Dyna Beads are not recommended for automobile tires. This is one of them things that worked this time, but maybe next time, and maybe not for you.

I have an old JC Whitney auto tire bubble balancer that I've used for years on cars, bikes, trailers and hacks with good results, even on race cars and bikes.
They may still have them available.
