Why We Like The Byway Road TCS Tire

Our rides rarely stick to one surface anymore, snaking between dirt and asphalt as we uncover those hidden scenic vistas. The WTB Byway’s tread pattern gives us the smooth roll we need on pavement with the semi-slick center, transitioning to a hatched diamond pattern for plentiful grip when you're grinding along dirt and gravel surfaces. Raised side knobs offer more grip for cornering on dirt, as well as durability for exploring off-road areas where rocks and sharp debris are common. Three size options and tubeless set up make sure we have the right tire both for our frame and destination.


  • 700c all-road tire for dirt and asphalt rides

  • Dual Compound DNA rubber for rolling speed and grip
  • TCS technology ensures tubeless reliability and grip
  • Smooth centerline is fast over paved road surfaces
  • Diamond-hatch transition for off-road grip under power

I like them

I've put it through the wringer
Size Bought:

I've got three of these in service (one for a spare wheel) and I've had quite good luck with them. I converted a Specialized Roubaix to a pseudo gravel bike and the 34s were the largest tire I could fit. Yes, they definitely leak through the sidewall, as I've noticed for tubeless tires in general. I found that adding some extra sealant takes care of the leaks quite nicely. I recommend them.

Worse possible tire

I've put it through the wringer
Size Bought:
6' 4"

I do not usually write reviews, but I wanted to warn everyone about these tires. I am sure they are fine if you run tubes, but for tubless tires, they are horrible. The seams will continue to leak and leak and leak. I even had them go flat while riding twice with no punctures (bead gave out). I ended up returning these and getting another brand. WHen I talked to my LBS, they found the same issues and even stopped carrying this tire.

two instances of snakebites on treat

I've put it through the wringer
Size Bought:
5' 1"

Twice now I have replaced my back tire with these -- twice it has busted on a smooth road with only a small slit across the top of the tread. It makes me think there's an issue with the rubber itself. I ALWAYS check my tire pressure before each ride. I never had issues with sealant but after replacing this twice I am moving on to another brand.

Ride decent, but a nightmare coming off

I've put it through the wringer
Size Bought:

I have no gripes about how the tire goes on the rim or how it rides, pretty respectable in both categories. My (BIG) problem was when it came time to remove them. They were so plastered to the rim I couldn't budge them with my hands or even any of my standard bike tools. Mind you, I've been an avid cyclist for decades and have plenty of experience with such things. I had to finally resort to the kind of thing you're NEVER supposed to do -- whip out big boy tools, namely, my largest vice grips to clamp down and leverage the tire off with way more force than my hands ever would have managed. WTB -- not cool!

They don't hold air well and run small

I've used it once or twice and have initial impressions

Like others have noted these tires leak air bad when setting up. They are also pretty challenging to get on the rim, but not impossible. The snug fit does give me confidence, but I don't look forward to removing them. Here's the best advice I can offer for getting these to seal up and hold air and tubeless fluid: DO NOT ADD SEALANT RIGHT AWAY 1. Get the tires on and the belts to seat on your rim. Pump them up to near max inflation and observe. Air will probably leak out of the sidewalls pretty rapidly. You can confirm this with soapy water. 2. Add sealant through your valve stem. 3. Replace the valve core and add just enough air that the tire isn't flat. DO NOT PUMP IT UP TO FULL. At most go to the bottom of the tire's recommended range; like 20-30psi TOPS. Any more than that and you will leak a lot of sealant through the tires. 4. Slosh the fluid around inside coating both sides of the sidewall and let the wheel sit on its side over a box or a bucket or something to protect your disks/hub/cassette/etc. for like 10-20mins each side. 5. After doing step 4 a couple of times per wheel, add more air and give the wheel an occasional spin on your bike. After a while you should be losing about 10-20psi per hour; which is way better at this point. 6. Pump the tires to max psi and ride the bike about an hour or so. Your tires should be pretty sealed up at this point.

Installed them and saw/heard air bubbles of sealant out of the front and back upper sidewalls! Waste of money, sealant, and time.

Skip these

I've used it several times

It's true, they do run small. I wanted to love theses tires so bad, but after running 40's which are 35-38s in other manufactures specs I upped the size to 44. I immediately noticed sealant leakage when they were first put on, but I was hopeful. Sadly they flatted, spurting sealant within the first 5 miles of a planned big ride. That was just the back tire, which I ended up swapping. On a ride shortly after the front tire went. I wouldn't trust these tires if someone paid me to use them. They are easy to put on and would be better ran with tubes than tubeless, Like I say in the title, skip these, they aren't worth the heartache...

Will not fill air even with compressor

I returned this product before using it
Size Bought:
700 x 44

700 x 44?s Surprisingly very easy to install, getting air into the tires is a nightmare. Installed on Zipp 303 NSW disc wheels. Front set up took 3 attempts with compressor, minor sealant leaks but sealed after 5 minutes. Tried 8 times on the rear but to no avail, would not inflate at all. Called it in to ask for a replacement tire. Hoping it?s just a defective batch, will report back when I get the replacement.

Great mixed surface tire

I've used it several times
Size Bought:
5' 9"

I got the 700x40 tanwall tires for mixed surface riding right from my house (gravel doubletrack, bike paths, roads) and they perform well as an all around tire. Surprisingly grippy climbing on gravel, even out of the saddle if it isn?t too lose and pretty fast on pavement even when running lower pressures. The tan sidewalls are awesome. Pretty easy to set up tubeless with an air compressor. Had one spot on the rear that didn?t want to seal after a few rides, but some extra sealant solved that. Unfortunately they didn?t measure true to size (36mm when first mounted), but have since stretched out to 38.5 (my rims are U28, so that shouldn?t be the issue). Regardless, great tire. If I were doing more gravel and less pavement, I?d go with the 44s if they?ll fit your frame.

Exactly what I was looking for on off road touring. It?s fast rolling and aggressive enough for what I need. Zero flats so far which was a big problem with previous tires
