Long story short I will definitely not recommend CST Conquistare tires. Wore out in less than 1200mi and then weakened which is just unacceptable. So thumbs down from me. This brings up two questions: 1. The Mr.Tuffy orange liners for 700c narrow tires. They must be laid in with a wee overlap. Will that overlap cause a 700c 25mm tire at 110psi to run bumpy? Like whop .. whop .. whop every time the overlap comes around? 2. What about taking a second (otherwise discarded) thorn-resistant tube, slit it open on the inside and slide it over the real thorn-resistant as a 2nd layer? The problem is that Kenda seems to have discontinued selling thorn-resistant tubes with good and most of all same thickness all around but now the thickness tapers off towards the sidewalls. That's where they fail. Same for Sunlite which I had to re-order yesterday because those things are essentially unfixable with those thin REMA patches. Any words of wisdom? As usual, weight absolutely does not matter. In case anyone knows: I read somewhere that smugglers "inflate" their vehicle tires with some sort of hardening sealant (Silicone? Construction foam?) that makes the tires bullet-proof. What material is it and how do they get it in there thoroughly enough? Would it be good for a couple of thousand miles? I don't know about smugglers but yes you can buy foam to use in tires. See https://www.youtube.com/watch?v=pgv4UiDQa74 http://www.accellatirefill.com/ and I assume other sites. Thanks. Tyrfil is what Andrew brought up and I'll contact them next week. I'd like to have a similar firm tire behavior as if it was pumped up with air to 110psi. Riding comfort isn't very important, durability is. A google search for "foam filled bicycle tires" gets 372,000 hits. such as: https://www.amazon.com/Bell-Solid-No.../dp/B01HY12VOU http://www.instructables.com/id/No-more-flat-tires/ http://www.livestrong.com/article/22...-tires-review/ I did web searches. None of the result were much good. I was looking for something that works, preferrably via squirting through the valve stem into a regular tube. There was a report of smugglers who had inflated their tires with something from cans and that made them not go flat when shot at. Unfortunately the report did not state what was in those cans. The main objective of my post was different though, this was just a side question in case anyone happened to know. There is a sort of "slime" that comes in pressurized cans that you can inflate auto tires with that will seal some leaks. Which you may have been reading about. But I suspect that you already know about that stuff. I've tried that stuff on my MTB. After a few months I had it with slime and threw those tubes away. The slime oozed out everywhere and I got lots of slow flats where I had to pump two or three times on the ride home. In any case that essentially ended the ride. Plus a green mess on the garage floor that the missus didn't appreciate. Especially because of the risk of stepping into a splotch and carrying it onto carpet in the house. I replaced them with thick and heavy thorn-resistant tubes plus tire liner. Never looked back. Now that one rider had sent me an email that tire liner won't cause uneven rolling on a road bike I ordered a couple rolls. Actually bid on them on EBay just for fun (my first time bidding). I ended up winning. $1.25 plus $4 shipping. If I'd order those at an online shop it would cost around $12 total, $20 at a LBS and I'd have to ride to Folsom for that. If they even stock them. Aside from all being "things which some people put inside pneumatic tires", there's no other similarity among Slime, aerogel foam or urethane sealer. Yes, I know, was just responding that I have tried slime and found that it does not work in the long run. I found that thick tubes plus liners work much better. Just wasn't sure whether there'd be a noticeable bump upon every wheel rotation but a rider wrote me an email that there isn't. So I'll try that. -- Regards, Joerg http://www.analogconsultants.com/ |
