I've been changing motorcycle tires for 30 years. You should never inflate the tire more than 50 lb when seating the bead. All these years I have never had to go more than 50 lb. If it won't seat at 50, deflate it, break the bead that has seated , Lube the **** out of and try it again.

oh, oh, ohhh, you're here to save us with this brand new information, right?
It prolly runs the risk of falling off the tire rack in a store and killing babies too, right?
If the difference in bead is so fricken critical, why hasn't anybody reported a demounting yet?
You need to get back in your fallout shelter and not worry about darksiders, OK.

Running the same car tire on the bike rear and on the sidecar works out great on the small rig. The handle better, the tires last 4 times longer or more. They stop better There is no downside. The larger rig runs a car tire on the bike rear and a different car tire on the sidecar..
I would not have a sidecar that would not take a car tire. You have never hear me passing judgement on someone running a car tire on the bike.

What the heck are you talking about. I run car tires on the rear and on the sidecars and will always do so. The 155/60R15 are for cars like the smartcar they are a light tire. Never had an issue with them before on the smaller rig and a friends just like it. When I have time out side I will try to figure out what went wrong . The tire split while being mounted. And contrary to the BS it was being mounted by a dealer that knows what they are doing and has mounted car tries for motorcycle and sidecar for a couple generation.

Don't think I'm against CTs. I've been running them since 1978 without a single incident.

ok. There is a bit of a difference when mounting a car tire on a 15 inch wheel. For some reason they fit a bit tighter. Getting the bead over the ridge on the inside of the wheel takes a little more air that it does on 16 inch. The 155/60R15 is designed for the Smartcar type cars. Not the strongest tire on the market. Not a lot of options in that size. I am going to try a different wheel there is a chance something is not right with it. Waiting on another tire have to order it. A pain to get the 15 inch on but I will do the next one myself.

Dang makes one wonder how much pressure it would take to blow up a tire! I cannot imagine how the heck someone could actually not see the tire was filling, stop and gauge it.
I do know they can be dangerous. It been way too long to remember all the details. But I knew a guy pretty well back in the 70s that was a logger. It was a family business with his brother and father. They ran a lot of trucks and he oversaw maintenance. Steer tires on Class 8 trucks can be 110 psi range. Well I hear he had an accident changing a truck tire. Somehow it exploded and broke both of his arms.

I tried to get a darkside mounted on my wife's Honda, since it has a Voyager-type kit on it, so won't need to lean, but the bike shop tried 80-90 lbs pressure, and it still wouldn't seat. The guy at the shop wouldn't go any higher. Is this high pressure something common to installing car tire on motorcycle rims? If so, how do you get them installed? Do you have to go to a car tire shop that has the cage? Next time, I would like to get that car tire on this bike, but seems like I'll need to find a place that will go to the higher pressures in order to do it.
