Strengths:
These babies are light,good grip in corners. Air up easy as tubeless with floor pump. Roll fast.
Weaknesses:
Rear wears quick. Not the best in mud.

Bike Setup:
A few bikes setup to ride at anytime.
Bottom Line:
Tire has not been bad. Been running these tubeless with Stans from new. Mounted and aired easy. I weight 180lbs and run these at 27psi front, 33psi rear with no problem. I ride the trails two to four times a week. and few of those ride are four hours long group rides with no problems. Wish the rear would last longer may get a year from it, front still look like it could go one more round.
For anyone riding in the northeast these tires should be good. Side walls are thinner and the normal ust tire so you have to be carefully of sharp rocks.

Weaknesses:

Bike Setup:
Hardtail, XT/XTRish, Front Wheel:Mavic 717 with Stans Rim Strip, Rear Wheel: ZTR 355 with Yellow Tape, V brakes no disc
Bottom Line:
For starters this is a lightweight racing tire. It is meant to be ridden at low pressures to maximize grip and to be used with sealant. I'm 175lbs and ride them on a hardtail at 27psi. I've done 7 races on them this year including all my training. The races have been everything from dry and fast to wet and super rocky (Michaux stuff).
Running these tires at high pressures will not work! They will slide out and the sidewalls will tear more easily LIKE ALL TIRES.
If you want a light race tire for tubeless conversions, these are a good balance of weight, grip, longevity, and toughness. If you want a super tough and high traction tire then buy something else.
4 Chili's all around since there is no perfect tire, just good ones.

Strengths:
Well, they came with the bike so I guess that would be a strength. They roll very well on pavement and hard pack, making climbing in this kind of terrain easier.
Weaknesses:
There just isn't anywhere enough grip on these tires. I've read they work best tubeless at low pressure for light riders, but that isn't an option for me at 185 lbs. I just couldn't feel secure enough on these tires doing my usual rides, and constantly felt the front wheel slipping out, a problem I've never had with Fire XC Pros. Off camber trails were hairy, and fast, rutty singletrack had me going considerably slower than on my usual Fire XC's.

Bike Setup:

Bottom Line:
If you're doing simple XC on predominantly hard pack, you'll probably like them for how well they roll. Anything beyond that, and I think you should consider something else with bigger knobs and more bite on the sides.
Remember, run the pressure as low as you can - high pressure and these tires DO NOT get along.

Bike Setup:

Bottom Line:
I was lucky enough to score a fuel EX8 late October last year and it rocks. The bike was bought with both enduro and adventure racing in mind. The down side to these in my book is speed of wear. I rode on these tyres for only 4 months and they were sadly ready for swapping out on the rear and on the way out on the front. Im 170lbs and my last set of tyres were maxxis crossmarks (on a Trek fuel8 06) and they lasted me nearly 12 months. I rode on the Bontrager XRs recently and on a rocky 30 mile XC race and felt damn safe on the bends compared to the skinny xmarks. I copped more pinch flats (n=3) than I have ever had in 3 years of XC and adventure racing using Xmarks... That being said, on the Bontragers took away that gnawing feeling that the front wheel would slide out at any given moment....Finally, I recently swapped the Bontragers for maxxis ignitors before the second round race, on the same track, in order to work out if I could find better combination of grip. These worked great on the downs and copped zero flats, but man they were slow as compared to XRs.

Strengths:
The tires ride fast and smooth over hard pack, rail trails and pavement at mid to max pressure. I have ridden a lot of rocky single track and they have performed quite well and at $20.00 a tire they won’t break your budget. If I didn’t do as much soft riding I would mount a second set.
Weaknesses:
Their drawback is how thin they are, although they are light they are susceptible to pinch flats and the surface between the knobs slice easily.

Strengths:
Extremely lightweight for a tubeless tire. Very fast roll. Looks awesome with the white labeling and hotstrip.
Weaknesses:
Not the best when it gets wet. But then again, Bontrager makes the Jones AC for that. you gotta compromise somewhere.
Similar Products Used:
Fire XC Pro, Bontrager Jones AC, Velociraptors, Mutanoraptors, Weirwolfs
These are awesome for their intended purposes. Key words being INTENDED PURPOSES. I work at a Trek (Bontrager) dealer so I get alot of inside knowledge.
First of all, a Bontrager "Tubeless Ready" tire is not the same as a UST tire. A UST tire is mavic-specific to work on mavic rims without sealant. That is why they are so much heavier than standard tires. Bontrager TLR's are designed to be used WITH sealant, which is why they are so light and comparable to using a stan's kit. In fact, it even says on the sidewall "To be used with tube or sealant only".
Second of all, since these are tubeless tires, theyre are designed to give the best traction at low pressures. A Bontrager tech rep specifically has said that for riders under 150, these tires are designed to be ridden at 25 PSI! So if you ride these at a pressure in the high 30's or 40's, then obviously theyre going to be slick and sucky.
Finally, these tires aren't the best in muddy conditions, but they are excellent in theyre intended purpose, which is a fast rolling crosscountry/trail tire. There is a reason tire manufacturers make such a broad range of tire types. Sure there are tires that grip in rocks better than these, but i gaurantee you its a slower rolling tire in flats.
So in conclusion, as far as Bontrager tires go, if you ride in alot of mud, get the Jones AC's, If you ride crosscountry only with smooth surfaces, get the Revolts. Otherwise, the Jones XR is a happy medium.

Good on road, park trails, rail trails, and dirt, durable and good lifespan
Weaknesses:
bad on rocks (and that's what most of eastern PA is like), not good in wet, not the best climbing tire
Similar Products Used:

Bike Setup:
GF Tass, disc brakes, otherwise pretty stock
Bottom Line:
I've used these for a couple years now, since they come stock on GF hardtails. They are great for easy stuff, basically anything dry and beginner. However they are not good at all in dealing with rocks. I feel like I slip right off of them. They're not great for off-camber sections either. At water crossings, sand, or mud I have no confidence in them (after learning the hard way a number of times).
They're durable and lasted me two full seasons. One fell off my car at 70mph (duh!) and they were still just fine. I'm currently looking for better ones.
In short, if you ride on pristene trails or a mix of road and trail, then this is your tire. But if you do anything more advanced you will be looking for something better. Be sure to buy the right ones- they're front and rear specific.

These tires came with the bike so I decided I would give them a try. Within a few weeks I got frustrated and went back to my Panaracer Smoke/Dart tires. The front tire couldn't hold a line. If I rode up the side of a slight ditch, the tire wouldn't grip & roll up the ditch, but would slide back down into it. I was all over the place on the downhill. The rear tire seemed OK, but wasn't special. I was running these tires with tubes.

This review is for the 29 tires, I put these on in March and just rplaced them. They only lasted me 8 months of riding. They wear very quickly, but for $20.00 what do you expect. Luckily I bought 4 tires when they were on sale for $20.00. If they weren't so cheap I'd be pissed.
This tire is perfect for dry-hard packed surface, they corner well and hook up really well.

Purchased At:
Wheat Ridge
Strengths:
Both front and rear:
- Light for UST. - Good tread pattern for loose, rocky or hard pack surfaces. - The front version is a fat 2.25. - Nice looking
Weaknesses:
- Two pin-holes and one gash already in the rear so it's looking like there is a penalty for the light-weight casing. - Rolling resistance seems a little high at low to medium pressures. - Sealant is still necessary.
I am disappointed in Bontrager's tire quality control or honesty in labeling. I bought a Jones XR Tubeless Ready front recently. The weight on the package and their web site says 535g. The actual weight is 584g. That's a ridiculous extra 49 grams or almost 10% error. And this is without the 30g of sealant that I have to use. The main reason I bought this tire and the messy sealant is for the weight savings. I can buy a light UST and not have to use sealant and it will not weigh a huge amount more.
Similar Products Used:
Many different UST tires and tubed tires.
Bike Setup:
carbon Fuel
Bottom Line:
A good start for tubeless ready technology. I am still running them after a month so I am fairly happy with them.
I'm only giving 3 for the value because of the claimed versus real weight issue.
