Strength:

Good grip in hard pack, low rolling resistance

Weakness:

Weird feeling when laying them over in a corner.

IRC has been kicking a$$ here for years. Unfortunately, their marketing machine isn't nearly as good as their product. Sadly, I don't think these will be in the US very much longer. These tires have been on my bike for 4 years or so, with a lenghly time off (work and injuries kept me immobile for 16 months). When I got back on the bike, I figured I will need new tires. These have several hundred miles on them, are cracking and the sidewall markings are all but gone. But, woudn't you know it...a scoop of Stan's, some air and they are back at it. Grip is STILL excellent in climbing, braking and turning here on the Georgia groomed trails. I'm running the 2.25 up front and the 2.1 in the rear. Both have worn admirably (I'm not a skidder) and I'm very VERY satisfied with this purchase. For east coast mud/rocks/snot, I'd recommend the Serac XC, but for the groomed stuff in Metro Atlanta, these get a HUGE thumbs up.

Strength:

dry perfromance, fast rolling, big volume, true 2.25, very light (for size), cornering

Weakness:

tracking, wet performance

I like this tire for dry conditions (although it's not bad in damp and wet). As opposed to the Kenda DTC approach, the Mibro has the soft compound in the centre and the hard stuff on the edge lugs. It works well in the knarly stuff, even with the open tread (as good or better than the Nevegal), hooks up very nicely in the corners. I've got the 2.25 and run at around 32 psi. Its a true size and big volume, but very light and fast rolling. Downside--tracking at speed, going really fast down something loose, it's pretty squirrelly. Open tread, no dedicated center blocks, and soft tread, makes for constant corrections. Here the Nevegal really shines in comparison--major difference.

Looks like IRC has withdrawn to the Japanese market--too bad for us.

Strength:

Light, fast rolling and ok as long as you have not gone past 1/3 of wear

Weakness:

As soon as it starts wearing out, the rear tyre does not have a single bit of traction left

Extremely light and rolls fast. Cheap for Kevlars. Kevlars take it all. Perfect with latex tubes.
Once they start to wear (1/3 of the knobs) they become extremely skiddy and can't even handle our local trails on a dewy morning ride. In 300 miles of trail use they changed from good funny tyres to appaling skiddy things. Don't last much.
Just get some better tyres (nobby nic's, etc...), pay more and you won't have to pay the earth for when they'll have you crash nastily.

Despite all this IRC is not selling their all-mountain's any more- these were really amazing tyres you could ride at 1 bar on techy downhills and trails with amazing traction!

Strength:

Cheap. Light, two 2.25s averaged 600g on my scale. My pair of 1.95s were under 500g each. Supple - soft rubber compound makes for a pretty smooth ride and gives gobs of traction. Fairly true to size. High volume, fast rolling.

Weakness:

Sticky/superslick mud is the death of this tire. Similarly, very wet conditions don't do much for it. They wear fast. That's what you get with a soft rubber compound. Short knob height.

I've had three sets of these tires, and never really been disappointed. They're a good all around tire for rocky, rooty trails. I run ~20PSI with tubes and rarely pinch flat. My only wish is that the knobs were a little taller and they made a slightly wider tire (like a 2.35). The knobs are short to begin with and when they wear, they're really short. They hook up surprisingly well though.

Strength:

Light, low rolling resistance, versatile.

Weakness:

Tread not deep enough to hook up well on wet climbs.

I didn't like these tires at first. Then I realized the more I rode them, the more I liked them. They are light and hook up well in just about everything, with the exception of wet rocky and rooty climbs. I believe these tires would be perfect if the tread was 1/8 deeper. Bite well in hard and soft terrain alike but they really impressed me with winter riding. Sidewall is strong and large volume allow to drop pressure to 20psi in snow and traction is unbelievable.

Strength:

Good cornering and traction in dry conditions, even loose gravel and moderate sand (no tire I’ve used does great in the sand)

Weakness:

Somewhat slippery when wet.


I run the 2.25” only in front with a Serac 2.1 in back. It isn’t huge, but the 2.25 is a significant increase in volume over a 2.1” tire. For the late summer dry/loose terrain, these tires are a huge improvement over any fast-rolling, sub-600g tire I’ve ever used. I’d swear I was using more of an all mountain type tire with the traction I was getting, but when I pedal or coast down a hill it’s obvious I’m using a much lighter/faster tire. Despite the fact that it has been mostly dry lately, I did have the opportunity to ride in a light rain a few days ago. Things really never got muddy, but the tire did fine with the moist dirt. When I hit a few rock gardens, however, I was surprised by how many times my front tire slid off the sides of rocks that I expected it to grip and roll over.

Although this tire is not great in wet conditions, I still think it’s a great tire. If you want a tire that does well in all conditions, it will cost you a few more dollars, a few hundred grams and a lot of rolling resistance.

Strength:

Perfect tire on your first or second ride

Weakness:

After your first or second ride they look like they went through a cheese graiter

I purchased these because they were cheap. I had ridden on the Nevegal UST for the past few seasons and they finally started to start looking a little bald. Nevegal UST's are a little pricey right now so I went with a cheap UST tire. Well, you get what you pay for. After 3 rides I lost a knobby and I'm probably just a sharp rock away from getting my first UST flat out on the trail. For the first few rides they were seriously a very awesome tire. Looking at them now, though, and noticing that once they wear so quickly the lose a little grip, I'll never buy another Mibro. I've gone through a few IRC Serac UST's in the front, but they didn't wear NEARLY as quickly as the Mibro in the back. I'd say only buy this tire if it's on sale for $10 and you only plan on riding it twice.

For the 1 or 2 rides before their unbelievably quick wear and tear starts to show, they handle very similarly to a Kenda Nevegal UST

Strength:

Excellent grip and control in loose dry stuff. Lightweight all mountain capable tire, 2.1s are only 520 grams.

Weakness:

none yet. possibly wear?

I ride a cross country bike, but the trails here are more all mountain; most people here ride trail or all mountain bikes. I wanted to get the grip but keep it light, and these tires have exceeded my expectations at 520grams for 2.1 inch . I went from panaracer duster ii to this tire and the difference is night and day. The climbs result in better grip but its the descents that I notice the most difference. I can brake even in loose stuff without feeling like im going to lose control. I am riding with a lot more confidence. Instantly made me a better rider; and I really needed to get better. I got a set of mine for 34$. Can't go wrong. (I have only tried this tire in dry conditions).

Strength:

Low rolling resistance

Weakness:

Almost no grip at all. Downhill the front tyre doesn't send the bike where you point it. Uphill (unless in desert conditions) the back tyre just spins hopelessly. They are not particularly light. Just pray you don't hit any wet grass!

The only reason you should own these is if they came with your new bike. Only ride a bike fitted with them if you have a death wish!

Strength:

Very fast rolling for a 2.25 tire. Lots of grip and confortable.

Weakness:

I heard about durability of rear tire on hard pack, but I am waiting to see. Nothing else found.

Great tire. I wasn`t very happy with Maxxis CrossMark 2.1 on my Maverick Durance with Fox 140mm Fork, so an All Mountain setup. Since I mounted last week the IRC Mibro 2.25 Tubless the handling changed dramaticaly. I was worried about rolling of 2.25 size, but they are fantastic rolling, lots of grip and confortable.
No I can take much more fun and advantage of my amazing Maverick Durance.
