Strengths:    A good all-around tire. Doesn't do great at anything, but does good at everything (not ridden in mud, though). Easy to mount, airs up quickly.

Weaknesses:    Suspectible to rocks after it wears some. Doesn't hold air completely without sealant.

Bottom Line:   
Does pretty well what the tubed version does (except that 120 tpi has a smoother ride). It mounts easily with a floor pump, but does not hold air well without sealant (OK with me because I always use sealant). I lost two of them to rock gashes that couldn't be repaired, and they still had 50% tread on them. As long as I can get them fairly cheap, will continue to use in the desert(though I am checking out similar tires as I find them for low prices).

Strengths:    Relatively affordable, excellent all-around tire, seats easily to tubeless & conversion rims.

Weaknesses:    Not quite as nice (or light) as the non-UST versions.

Bottom Line:   
These are really great "all-season" tires. I use them for XC racing in the summer and snow riding in the winter. They work well in mud and aren't bad at rolling in the dry. I suppose if you like changing tires a lot, then you probably could find more specialized versions; I like being able to just leave this set of tires on my bike until they wear out. For the tubeless aspect, they seat really easily (with floor pump & stans) on my Mavic 819 or 717 (yellow-tape conversion) rims.

I do agree that they're not quite as great as the non-UST version of the tire, but I've never had any issues with burping (I typically run at around 35 psi) or sidewall tears.

Strengths:    lightweught, easy to mount,good for all kind of terrain except wet, fast on tarmac, good cornering.

Weaknesses:    They tend to wear fast, and,lately, to tear down fast.

Bottom Line:   
after having been a faithful and satisfied customer for 3 years, lately my confidence about this tyres has fallen to zero.
& months ago I bought a pair, and on the very first ride the front tyre blew-up, after few more rides the rear tyre did the same.
I thought it was just bad luck or the rough terrain.
So I fixed them, after 3 months the rear collapsed again ( a 1/3 of inch cut).
I patched it again and continued to ride it until obviously It failed again.
I bought a brand new one for the rear wheel,yesterday went out for a ride, as I started the first descent, after 1 kilometer I heard a noise coming from the rear wheel, that was it, a 2 inch knife-like cut.I could not believe it, And I still can't.
I have ridden these tyres for almost 3 years without problems , what is it happening at Panaracer industries ?
did they make any change to the product, could it be only bad, bad luck?

Date Reviewed: May 14, 2008

Strengths:    Went on easy to tubeless rims

Weaknesses:    Not as good as the non-tubless Fire Pro's. wear is faster than both versons of Fire's. Ride is not as supple as the non-tubless. 40 psi and above to stop burping.

Bottom Line:   
I purchased them on the strength of the normal Panaracer Fire's which i thought were best for the sort of riding I do, however burping and sidewall tears made me purchase the tubeless version. The tubless version must be kept above 40psi to stop burping. The rubber seems a harder compound, however has the added benefit of faster wear(?)
The tyre is just not supple and can not soak up any of the smaller hits. It also seems to have missed out on grip. The tyre seems narrow compared to the same sized non tubeless verson? Again adding to the above problems. Will not purchase again. It may suit riders in hard pack areas on groomed trails, but not the loose gravel that is in my area

Strengths:    Good grip, corners well

Weaknesses:    Tread wear

Bottom Line:   
I run Nevagal 2.3 on the front and Panaracer XC UST 2.1 on the rear. Traction has been good. expecially on dry loose rock. I have been able to clean some climbs that I couldn't before.

Tire is a bit narrow, especially compared to the Nevegal. corners well. Tread has worn quicker than I would have liked. I bought two of these and have replaced one after about 3 months of riding. Had some difficulty getting the tire to run tubeless on my x3.1 rims, but they've been fine on Crosslands. I run with Stans, but have had so many problems with tubeless in the past that I always carry a tube, just in case.

I think these tires are good value for the money. I'd buy them again if you can get a deal on them.

Strengths:    Great all around tire.

Weaknesses:    Wears a little faster than the non UST version

Bottom Line:   
I have always been a fan of the Fire XC Pro. It is a great all around tire. Excellent on the braking, cornering and climbing. Yes, it is a little knobby to be running on hard pack, but you have to determine what is most important to you when riding all conditions. I have had no problems with the UST version with ripping sidewalls or air leaking. I always use Stans and have had no problems.

The sidewalls even stood up to a hard rock hit and the rim bent instead of the tire ripping.

I would highly recommend these tires. They are probably on the heavier side, but you also run less risk of ripping a sidewall, etc.

Strengths:    Grip and side knobs.

Weaknesses:    Sidewall tears

Bottom Line:   
Great tire. Sticks to most everything. Biggest draw back is the sidewalls. I do run stans and had flats from punctures. I also had sidewall tears that no amount of stans or slime would fix. They wear really well and give good performance until they are about bald. I finally had to replace them when the insides had more patches then rubber. I will not run them again just because of the punctures and sidewall tears. I will they were tougher because I really like the tires.

Strengths:    Pretty fast roller . . . doesn't seem as fast as my Weirwolf combo but it may be due to my flabby a$$ after hibernating all winter. Good traction on rocks in the dry. Adds a nice feeling of plushness to the ride despite the small air volume.

Weaknesses:    Puny tire width - 2.1" just barely. Hardly any tire volume - especially compared to the allegdly same sized 2.1" clincher version - so it flatspotted my Mavic 819 rim hucking 4-1/2'. Wet traction sucks rocks. Hence the lower tire pressure and the resultant flatspotting. :<

Bottom Line:   
Good traction in the dry on rocks and good rolling resistance. Tracks well enough in the dry. Squirelly handling through rock gardens because of puny tire volume. Not a good tire choice if you huck on the trail. Wet traction sucks. Not much of an improvement - if not a step backward - compared to my Weirwolf UST.

So far, all UST tires I've tried have sucked pretty badly. I don't know for sure why tire manufacturers won't release 2.3" - 2.5" tires (tire weight maybe given current materials technology and construction methods?) but I have a feeling a lot of my complaints are due to tire volume and size. I've had it with the current crop of UST tires. I'm going to use regular tires on my tubeless rims and fill them with Stan's to help keep them sealed.

Strengths:    Very good grip, predictable slidding, climbs well

Weaknesses:    easy to puncher, hard to patch punchers, high rolling resistance.

Bottom Line:   
I like this tyre alot, But I'm racing again now & I find it is just to slow to race on, I would ride it all the time otherwise. It is the kind of tyre you can slide through corners on & you don't need to stop peddalling, because it is so predictable.

Weaknesses:    Doesn't hold air!! What is the use of great grip, when it just doesn't hold its air? Had to use eclips sealant to get it work. And after only 3 months a very big "bubble" appeared on the font tire, just like a balloon. Very humpy ride!

Bottom Line:   
It's a piece of crap. Poor quality tire. Do NOT buy!!

Date Reviewed: November 11, 2004

Strengths:    I had heard some good things about this tire and decided to install them on my new '04 Jamis Dakar XLT 3.0. After installing them I did a quick urban assault ride, up and down a few flights of stairs, things like that. They are silly fast a good racing tire, much faster feeling than the Hutchinson pythons I had on the bike already. When i the woods, they seemed O.K. not nearly as good as the IRC Claw Comp in my opinion, which IMO is the best tire ever made for east coast riding. Fire XC seemed good on climbs unless you have to really torque the bike, it breaks traction easily and I didn't enjoy the wandering feeling it gave me when descending damp, slighty terrifying terrain, I have enough stress in my life and don't need any more grey hairs added to my head because of some MTB tires. On average they were O.K. not great.


Weaknesses:    Knobbs fold or flex too much, not enough bite. They slide off of burms, which personally, I don't enjoy doing. It's not as amazing as the IRC Claw Comp.

Bottom Line:   
I probablly wouldn't reccomend them to a customer simply because I didn't feel confident on them I was sliding all over the place which I think makes for a bad day eventually. If some one wanted a racing tire and didn't care about slipping and sliding a little, then I'd say try them. Pytthons provide a better footprint which helps stabilize you and your bike. I don't get the whole move to skinny tires on Mountain bikes, everyone I ride with who uses skinny tires spends most of the day talking to their bike and trying to convince it to "stick". I thought I was weird because I like to talk to my dog once in a whie, but phew!
I'm running a full susension bike which enhances alot of things ( positively) in regard to trail rding/racing, but these tires made me want to go trash picking for my old Fisher Procaliber hardtail and slap on some Fisher fat trax, they felt more secure.

Strengths:    Durable, wear slowly
Grip, plenty of traction when not overinflated (35psi is good)
Hold air very well


Weaknesses:    Must use Stan's, added weight , oh well
Special trick to patch correctly, read on


Bottom Line:   
Very good XC tire. They wear well, took over a year to wear out a pair, I rotated them a little bit past mid-season becasue the rear wears faster than the front of course.
I have flatted these several times (low pressure and rock gardens) but the Stan's sealant has kept them from completely deflating.

The inner casing must be scrubbed clean of the oily release residue from the manufacturing process before patching. I use denatured alcohol and a green plastic scotch-brite pad, then clean with regular rubbing alcohol and make sure it's very dry. Roughen the area where it neeeds the patch, then patch it like you would a tube. Works every time, even right next to the kevlar bead!! I had 5 patches in the rear and 3 in the front when I fanally wore them out enough to get a new pair.

I won't switch tires unless something as good and cheap comes along. Buy them in pairs when they change model year, the price drops by half.

Strengths:    grip, light (relative to some other ust tires)

Weaknesses:    punctures easily

Bottom Line:   
Everyone complains about these tires. I grew up with panaracer back in the day with the smoke and the dart, and I saw these tires for $25.
I used 2 cups of stans for desert riding with cactus, rocks, drops, sharp stones, goatheads.. and never looked back. These are a classic reliable tire and when they puncture, stans comes to the rescue in a few seconds. Good grip, fast, and sticky on the climbs. Not bad. They do puncture a bit easier than IRCs and some others but the grip is better and stan fixes this puncture weakness. I would like to see a 2.2 or 2.3 version for better float through sand and loose stuff.

Strengths:    Their very fast and move through almost anything in front of them. A very well built UST tire. Also mounting these tires are so easy. I love tubeless tires.

Weaknesses:    None so far!

Bottom Line:   
The best all around tire I have ever used. One thing I did love about these tires they hold air well without Stans. Going to break them in and then add Stan's later. The tires buzz through sand, rocks and mud without any issues. I have the PSI set at 35 lbs. Thats a pretty good weight for those tires and have made me a better rider. They grab the trail like no other tire I've ever used. They shed mud really well. Get these tires and be happy on the trails! Best tire out there.
