Took the front wheel out of the fork to measure it more accurately against the wall and I get 705mm. It's not 2.2" wide, but it doesn't look as wide as the older 2.4" TKs.

I'll get some caliper measurements tomorrow for the width.

What was the internal width of the rim you used when you measured your 2.4" TK's and at what pressure? How old were they and which version?

23mm internal. 25 psi (though my riding pressure is consideriably less). Same width and pressure I've used to measure many 27.5 tires and a number of 26 before that. I use the same wall and a level.
What you're getting isn't a small difference - it's a solid 8mm or 1/3 of an inch smaller than previous TK 2.4.
Mine were ordere from CRC about 3 months ago. They are the Black Chili Protection version.

I ride low pressures. Checked my front tire and it was at ~17psi. So I pumped it up to 25psi. This is all measured using a floor pump so I can't say the readings are accurate.

Anyways at 25psi the tire is ~4mm taller so say ~709-710mm.

The rims I am using are hookless so they spread the tire out more than the same width rim would with rim hooks. The difference in width gets us closer to the same measurement.

Not that I know of.. I would personally run the skinny tire on the back it's a faster set up and I find you can rush into the rough stuff without a care in the world ... or brakes lol

Was that directed at me? My daily driver is a DRZ400 and just started riding in single track in May when my wife picked me up a Marlin 5 for my birthday. My DRZ has a wider tire in back as do all MX and Dualsport bikes. If a skinnier tire makes a bike faster why on they do that on engine driven bikes? My Marlin has a differnt size tires stock that make sense with what you say (29x2.2 fron and 29x2.0 rear). Treks other bikes have matching tire sizes front and rear. Riding a hardtail I get in stuff where I get beat up with the 2.0 out back. I want to put a b+ on the rear. The frame apears to have the room for the b+. I have about 12 mm on both sides and the seat post.

It's easier to pedal and rolls easier .. on a dirt bike you want meat back there so it doesn't spin .. I didn't mean to come off as the B+ on the rear is a bad idear, they rock and really give a hardtail some suspension to work with

WTB Scraper Rims mounted up with the Breakout 2.5. The tires measures 28.25 inches tall, and between 2.6 and 2.7 inches wide.

The Bontrager XR1, 29x2 with standard 29er rims measure 28.25 and 2.04 inches wide with 40 psi. I have close to .500 on each side of the tire in the frame and that same amount in diameter. I think dustyduke has posted my perfect size.

Dusty: I'm not looking for a 27.5+ but I do like as tall as possible non-plus 27.5 front tire.
So far the tallest I've found is the Trail King 2.4 (713mm) and the Goma 2.4 (713-714mm). Both are several mm taller than popular 27.5 tires like the Magic Mary, Minion, HRII.
If your measuring is accurate it puts the Breakout at 717mm so I'm eager to try it out. Looks like a great 27.5 tire.
Since everyone's measuring could be a bit off I'm curious if you ever measured the Trail King 2.4 or Goma 2.4 and if indeed the Breakout 2.5 is taller?
Thanks for your help.

Ya, its a super tall 27.5 tire. I even mounted it on the WTB ASYM i29 to make sure it kept its height and it did. I have been riding it in the dry, blown out and loose stuff and it is awesome. Highly recommended.

Considering it weighs as much as the WTB Trailboss 3.0 and is close to the weight of a Bridger 3.0... Does it feel like it weighs that much?

Not really to be honest. Something to think about is that the Trailboss 3.0 weights 1125 grams with a light weight casing. The Bridger is over 1200 grams and also with the light weight casing. The Trailblazer is just shy of 1000 grams and comes in the light weight casing. The Breakout 2.5 has the heavy duty enduro casing, which is a nice feature and it weights 1110 grams.

Between the Breakout and the Trailblazer, there is a noticeable difference in weight on the trail, but once you point the bike downhill, the two tires act very differently. I feel that I can ride the Breakout much more like a normal tire since the side knobs are very pronounced, while the Trailblazer has much smaller side knobs.

When leaning the bike over, if you lean the Trailblazers to far over, you will be riding on the sidewall and have no traction. I have yet to lean the bike too far over with the Breakouts on there.

The Trailblazers are a great tire and I enjoyed the heck out of them. Its just nice having the cornering knobs of the beefier tire.

IMO I wouldn't call the Trailblazer a great tire. It's a great compromise and I think it's awesome that WTB had the cojones to design, build and bring something like this to market. I also think it would be a decent tire for gravel road bikepacking adventures. It's small tightly spaced knobs, centre line and hyper square profile limits it's use in technical variable condition trail or all mountain type riding. For everyday riding on the full suspension I'd pick a more aggressive tire from their line up for sure.

It's a great rear tire

I never tried it that way though I may still when I can find an aggressive front to go with it. Now that Maxxis is coming out with their plus lines I suspect I'll just pick up a couple of those and give them a shot. Never been disappointed by their tires.

Hey Guys,

As promised, here are some pics of my new SC Heckler set up B+.

I had ordered new rims and hubs to build up some normal 650b wheels, but decided to try the bike with the WTB i45 rims first. I am sure glad I did.

On that same note, I didn't order B+ specific tires, but used the WTB Breakout 2.5. It has a smaller b2b compared to the TrailBlazer 2.8, measuring between 60 and 62 compared to the 65 of the TB. Overall, I think I actually like the Breakout better. The tire casing is much more square, and the tread pattern has a nice round shape. Talk about traction and wanting to throw your bike into super techy descents!

The knobs are huge, and are nearly inline with the sidewall casing. If you have been on the fence about B+ tires not being meaty enough, I would highly recommend going this route. The tire measures right at 28 inches tall. I will get a width measurement and edit the post
