Strength:

Very fast with no roll resistance. Excellent for city and trail riding. Best tire I have ever road on pavement. Has enough volume to ride off road on crushed limestone trail and gravel. I stated, very fast, even off road. Specialized made a big mistake when they discontinued making them.

Weakness:

Specialized quit selling them.

Excellent tire. The best you can ride. Specialized made a big mistake when they discontinued making them.

Strength:

Armadillo is tough
good long-wearing, sticky compound
well-aligned mold
hi pressure
easy on and off

Weakness:

very round profile (wekaness imho) tries to ride over debris instead of popping it off to the side.
only available in 1.5" for 26" rims
heavy
fairly harsh ride

i don't like punctures. in fact i hate em. they usually happen when i'm under time pressure to get to work, and they usually happen about 1 mile left to get to work, so it's either quick change the tube or run the last mile; either way it sucks!

i had been riding nashbar 1.2 inch slicks with sealed tubes for a long time, and got a flat maybe every 3-5 weeks on average. usually just a piece of glass finally worked through, the usual. but i reasearched and finally tried these Nimbus EX Armadillo, spending about 3x as much as usual.

They are HEAVY for a slick 1.5" mtb tire, and since all that extra weight is rotational, it hurts the most. that said, i run 100+ psi (up to 120) with no issues and can average 17mph on my cross-town commute including slowing for signs, traffic, etc. So not too bad. but i throw on the n-bar slicks for events, and those make the bike feel like it's flying by comparison.

The compound is very good, securely and predictably sticky and yet after maybe 1500miles, lots of tread left. The tire rides rather harsh, likely due to the tread protection.

The width and profile is just perfect to make the tire skittery over debris. The tire ends up picking up a lOT of garbage in the tread, but the Armadillo handles most of it.

2 of the 3 punctures have been due to catastrophic punctures; a key (as in a FRIGGIN HOUSE KEY) punching right into the tire, and chewing up the rim strip and inside of the rim) and a screw (as in a FRIGGIN 3" ROOFING SCREW) punching right into the tire and similarly munching the rim strip and rim. I have never ever had issues like THAT before, with any other tire setup! I blame this on the w-i-d-e profile, the garbage gets bounced around by the front tire and WHACKS! into the rear.

the final puncture was frustrating: a slow leak kept popping up every week or so, i kept examining the tire, and finally found one of the steel cords of the tire, FROM THE FACTORY, sticking into the inside of the tire and slowly working it's way through the tube, causing an infuriatingly slow leak. garrr....

but hey, that's 3 flats in 6 months, not too bad, considering the abuse i put it through. About 2 miles of my 15 mile commute are in the 2ft wide shoulder of a major road, and is compelety strewn with roadkill, shrapnell from accidents, glass, random car parts, etc etc. I've pulled some nasty-looking crap out of the tread that didn't manage to make it through to the tube. So the principle is good, but the huge profile (and in my case, steel cord in the tube) doesn't help on the execution.

Impressively enough, the tread is so tough that the hole made by the key (about 1/4 inch long) is barely visible as a small bump on the tread with 100 psi in the tube. Now that's a tough, rigid tread!

I have to only give it 3 chilis, for the above issues. If Specialized made it narrower and lighter (should come with narrower) it would be a 5-chili ride and 'd be happy to pay the $30. As it is, i just hunted down some $30 Panaracer Paselas and will give them a go.
Cheers

Strength:

Strong, little rolling resistance, and long lasting.

Weakness:

Tires are hard so the grip is not the best on the road and off road or loose gravel/sand you will have problems.

I'm been running these tires for about 3 years with over 2000 miles on them and have never had a puncture. I run over glass, through thorns, you name it and nothing has gotten through. I've put about 500 miles on 'rail-to-trails' paths through Western South Dakota (Black Hills) with no problems except sinking in on loose ground.

If you want to commute without worring about punctures, this tire is for you.

Strength:

Fast, puncture-proof(well, tried riding over thorns, broken glass, etc), very durable!

Weakness:

Extremely difficult to remove and fit or vice versa..

These tires are fast and simply don't wear out even after locking the wheel to a halt on tarmac!.... and it's been rolling since '95(Mine is the much older model with the dark brown sidewalls). Furthermore, they sure are tough.... don't look at them as slicks... they have the rubber compound 3 times thicker than most off-road tires made these days!.... have not had a puncture when using these and now they have gone over to my tandem coz these tires could be trusted.... and guess what? With all the added weight, the tires still hold...with all the grooves still freshly embedded on the surface without any wear....
Get these and u won't need another set of tires for a preeeeeeeeeeety long time!

Strength:

Great ride compared to nobbies that came original on the bike. Have not had a flat since i have owned them.

Weakness:

Extremely slick on wet surfaces.

Do not be fooled by some of these reviews that say these are grippy on both wet and dry pavement. These cats must have a different version from mine. First day I rode with these on my bike, I fell and fell hard. If you buy these tires and it rains, I would recomend walking. But, I have even slid out with nobbies in the rain. Come to think about it, I may just be a bad rider. Do not get me wrong though, I love this tire. If you are like me and are a daily comuter, this tire would work great for you.

Strength:

grippy, roll well, hardwearing, seem pretty puncture proof, cheapish

Weakness:

a little tricky to get on and off without levers, look a bit daft on a bike with disc brakes. Obviously rubbish in mud.

I have a 13 mile ride to and from work, largely on road with some gravel paths and these things are just perfect. They're even ok on dry grass trails. If you put 50+psi into them they swish along really nicely on the road and you can spin along a gear or so higher than you would with knobblies on. Bit of a harsh ride on the rear combined with a stiff hardtail but what do you expect? Great grip in the dry, add with disc brakes you can stop pretty flipping quickly, useful in the London traffic! Come the weekend, whip them off, stick on the 2.1s and find mud. 4 points because they're a bit heavy and they don't grip on wet manhole covers (8^]

Strength:

Did not get very many flats at first. Low rolling resistance.

Weakness:

Loads of flats after the tire wore--the Kevlar doesn't protect you. It's not the Kevlar that prevents the flats, it's the rubber

Kevlar is a scam, in my opinion. I didn't get very any punctures if any at all when I first got the tire. But as it wore, I got loads of flats. Sometimes two in one week (all I use the bike for is to commute to work each morning in central London, 5 miles each way). I got rid of it because I was disgusted with the flats. All it takes is a tiny piece of rock or glass and it just goes straight through the Kevlar. My bike shop told me that the best-rated tires for puncture resistance don't use Kevlar, but use strong thick rubber. Kevlar, apparently, is great for stopping bullets, but is impotent against a small piece of rock/glass that slowly rocks back and forth and penetrates the Kevlar like butter. Kevlar is great for a wide impact (bullet), but defenceless against a sharp attack, particularly one that slowly works its way through the Kevlar fabric.

Strength:

One flat in one year, including 6 months messengering.

I have the Numbus EX's. Great slicks. Can't recommend them enough. I have two wheelsets -- one of road use with these tires, one for off-road use with some nobbies on them. These tires turn my ATB into a road bike. You will not be disappointed.

Strength:

Specialized Nimbus Armadillo 26x1.5, front and rear.
fast on pavement, had travelled 600m so far on these, enjoying them over fat winter rubber

Weakness:

slippery on even small amount of sand - watch out when braking!
Fill slow uphill, but can actually accelerate uphill if you push it.
Also - less shock absorbtion and a bit heavy for their size.
Oh, yeah - allow yourself enough time and patience to put them on first time!!!

great for city with less potholes than Boston/Camrbridge and better roads overall
