    Specialized Tires...Nimbus

    OK I had enough. Recently purchased a set of WTB Slickasaurus tires for my bike (26x1.5). Since it's been raining off and on here in SoCal I havent had a chance to put a lot of miles on them. But, when I have had the chance to ride I got 3 flats in less that a 100 miles riding. I'm done with them. A friend said to go with Specialized Nimbus Ex tires. He never complains about flats so I figured I'd call the LBS and get a quote. They are an authorized dealer so I figured this guy knows what he is talking about. Turns out this guy says go with the Bontrager tires instead. When I mentioned the flak jacket protection with the Nimbus he said it really doesn't help much if anything. What gives? Any suggestions? Need something that will not puncture or pinch so easily. Also, I will run about 80 psi on them. Thanks

    Flak jacket helps with pieces of glass that would normally puncture in 1 go. An armadillo might hold off for many pieces of glass. The rubber compound used in my armadillo tires seem to fend off glass getting stuck in there. Like it's more resilient and doesn't allow glass to "sink" into it though I do end up picking 10-15 pieces out each month.

    Keep in mind though, if you get a piece stuck in there and it consistently grinds it's way through the threading, nothing will keep you from getting a flat.

    I've noticed though that the armadillo's feel about 25% less "lively", it feels like I'm riding on flat tires even though they're not flat and pumped to the max PSI. The ride feels more sluggish to me but hey, they're only on my commuter bike.

    Right now I have the specialized tri sport with flak jacket. I dug 3 peices of glass that were in prety far in the tire. No flat.

    All my flats were a result from glass getting in the tire. The Armadillos sound cool. I went to the Specialized site and I like what I read. Thanks guys.

    I've been commuting on armadillos since last fall and have not had a flat. I ride almost everyday. The tire rides a little harsh. I put in 90-95psi. Can't be beat for commuter tire. I'd ride something else for a century though.

    Been on the Nimbus EX's for four years never had an issue with them. I've hit almost anything you can think of on the road and cmae through smiling. Original tubes too.

    I think they're meant as exactly that... a tough commuter tire, not a tire for long distance riding at high speeds.

    That's exactly my experience of the Nimbus Armadillo: tough, but a bit wooden in riding. Skiddy on smooth ironwork. As an everyday commuter tyre they're pretty good. Last summer I switched to the Conti Sport Contact which (so far) has been flat-free and a lighter, more lively ride.

    I rode the Nimbus Armadillo's last year and have to say that it was a pretty tough tire...but no feel. This year I have switched to the Nibus Ex with the Flack JAcket protection and and pretty pleased with the ride. So far I have been flat free ecxept for a pothole that took out my rear wheel.

    Me too. three years, probably 6-7k on those suckers, the only flats I've ever had was pinch flats when I took knobbies off and on. I think I changed one tube because of a pinch flat. Ridden over glass, metal, rodents, etc. Now that they're bald they're a little slick on wet or muddy surfaces though. geez I want a refund

    Unless the pics on the Specialized website are wrong, the Nimbus EX and Nimbus Armadillo have the same tread pattern. The Armadillo might feel "rougher" when riding because of the stiffer sidewall they tend to have.

    I have Specialized infinity armadillo tires (700x32) on my tourer/occ commuter. Guestimate would be about 3K miles with only one flat, from a wire off a car/truck tire (somewhere in Romania or Bulgaria over the summer). These only come in 700c, but its the same "technology" I suppose as the nimbus armadillo, just a different tread pattern.

    Notes: They're heavy. My rear tire seems to be wearing flat, increasing the road/tire contact area (patch). About half of my miles on this set were from a self contained tour (so the load on the tires was considerable). I accidentaly cycled through broken glass (a lot!)-and waited for the pfffft-didn't happen. Also, I usually keep my tire pressure rather high (>100psi), so this may increase tread wear as well.

    I could see how the stiff sidewall would help prevent pinchflats if running lower pressure-I had to deflate in Istanbul to fly, and was still able to roll the bike without bashing the rims.

    I have to put in a good word for the Conti sport contacts. Best tires I've ever ridden on. They ride at a high PSI and are thick enough that they pretty much crunch any glass they roll over. I'll seriously miss those tires, since my new bike uses 700cc's and the SC's don't come in 700 x 38 or 700 x 40

    I've picked glass out of a flak jacket Mondo (23c, totally slick road tire) tire that had been there a while. It had worn smooth and flush with the rubber around it, but it didn't reach the tube. I've had Nimbus tires and never had a flat, but I did tear the sidewall, so I'd go with the armadillo version. They're heavy, but the sidewalls are pretty beefy. I've been riding flak jacket road tires for a couple years now and only one long fat thorn has made it through. I've had other flats with them (pinch), but only one puncture that I can think of.
