How could I put oogoo inside a bike tire to make a solid tire?

I think oogoo would be a great material for a solid bike tire, the only problem is it wears away pretty easy so it would be nice to be able to put it inside a regular bike tire in place of the tube. I've been racking my brains but cant think of a way I could avoid air pockets and was hoping someone would have suggestions. Thanks. By the way i know solid tires ride different. I have them on one of my bikes now and they're a lot harder material than oogoo but I'm thinking oogoo would be hard enough.

I've seen kits that do exactly this. It puts some liquid into the tire and expands or someything. http://www.mec.ca/product/5039-424/orange-seal-tubeless-sealant-8oz-winjector/?No=80&h=10+50002+50012+50182&f=10+50002+50182. It adds about 120 g per tire I think. This would be way more efficient. You could google tubeless conversion kits. Sugaru is aboyt 55 cents a gram and tire sealant is 6 cents a gram so way more cost effective.

That kit is sealant. It stays liquid inside the tire until you get a puncture and then if the puncture is small enough it will seal it. I'm not using sugru. I'm using oogoo, a sugru substitute that is a lot cheaper. See this instructable: https://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/ The corn starch is a dollar per pound and the caulk I get on sale from Menard's for 1.50 per tube.

Should still work. I copied the wrong one http://www.mec.ca/product/5029-876/stans-notubes-tubeless-conversion-kit/. More or less the same idea. I think oogoo would be too difficult to get in evenly since it needs to be hand moulded. You could do it I suppose but the tire may be unbalanced. I was thinking something like a squeeze bottle with a schrader valve adapter on the end and pump it into a tube.

That is exactly the problem. How to get the tire evenly filled with oogoo so it will be balanced. The tubeless conversion kits are both just sealant. I'm not trying to make tubeless tires, I'm trying to make solid tires by completely filling in a regular tire with oogoo. Solid tires is the goal. Some sort of solid tire, the simpler to make the better. I mean not so simple as in just riding on the rims. (I've done that, it's quite noisy and the handling is not great).

Oh sorry I thought they expanded into a solid my bad.You could try putting some holes around the tire without the tube and use spray foam. Just put a new hole every few inches and try and get as even as possible. If done right it might just fill in evenly without lumps but not sure. The only problem I see with the oogoo is it is not viscous, very difficult to apply. Possibly cement would be an option? Cut a slit in one side and pour it in and try and spin it so it is even. Would be hard to start, and stop, but it would be a solid tire.

I think cement would work but would be heavy? Isn't cement heavier than rubber. I guess there's aircrete that uses styrofoam beads as aggregate to make it lighter. I'm pretty sure smooth on makes just what i'm looking for-casting rubbers/urethanes of different hardnesses.Their products are expensive though, like upwards of a 100 dollars for one gallon. i'm wondering if I could use the spray foam like you said just to make a foam cast of the shape and then recast it in a 2 part mold with oogoo.

Yeah casting might work the best, much better control. I think if you used the right cement it would be fairly light. It would look pretty bitchin to take off the rubber and have cement on cement lol, might be slippery.

I guess you could BUT Unless you only ride on glass smooth roads your going to find this very uncomfortable. That's why they invented air filled tires in the fist place.

You could try filling the tire with expanding foam if what you need is a puncture proof tire.

Also my solid tire bike is 700cc, the skinniest tires you can get. When compared to a 700 cc air tire I'd say it's very similar, especially the new high pressure tires that people ride. When your pumping your tire up to 100 or more psi it doesn't really have any more 'give' than than my solid tires do. Also rubber comes in different hardness. If you want some solid tires to emulate a 40 psi mountain bike tire you can get it, but the higher psi you ride, the less rolling resistance there will be, and if youve got road tires there wont even be much weight difference. Another thing-tubes, rim tape, patch kits. None of that stuff is free. Not needing it is kind of nice.

I already ride airless tires on my main bike, a road bike, which I'm not trying to ride on bumpy roads anyway. On a normal road they feel just the same also they dont get low and air and suddenly it's way harder to pedal. I don't have to check the pressure everytime I ride somewhere. I'm not constantly worrying that I'm going to get a flat and be late/stranded. Air tires seem like an odd design to me. Seems like on a car you could get the same effect by way of some sort of additional fine shocks or something. The foam would work temporarily but I imagine it would take on dents too easily.

Pull the tire, Fill it up and put the tire back on. You'll still have the gap between the rim and the oogoo. but at least it will be well distributed and some what balanced.

That does seem like the simplest solution. I like it. Thanks. I think I've been building up this question too much in my mind because I'm sort of poor and oogoo isn't free. I am wondering if I'll either have to cut the 'bead' -that metal wire strip that runs around the tire-in order to be able to get the oogoo inner tire on and off. Also, what would be a good release agent to use. Do you think a rim tape would be enough and then it should release from the flat metal just fine?

If you fill the tire before mounting it on the rim nothing will be touching the rim.
