WTBRaddler TCS 700c Gravel Tire(Return to Product Page)

WTB Raddler is a great gravel/trail tire. I have only 2 blocks of road to get to the dirt so not many road miles to rate. On trail, these are the best. I came off the Specialized Pathfinder with the smooth center line and side knobs (if you can call them knobs?), and found MUCH more traction on the Raddler. They do run small for the size my 44 Raddlers are the same width as my 42 Pathfinders and narrower/shorter than my 45 Maxxis Ramblers. The Raddler is my favorite gravel/trail tire because they are narrow enough to not fold over on fast turns, the side knobs (which are tall and well spaced) really hook-up. I love being able to lean the bike over on dirt like I do my road bike on good tarmac. The check pattern in the center hooks up on loose gravelly climbs in the saddle and does a FAR superior job hooking up on climbs out of the saddle than any other gravel tire I've used. The other benefit of the center tread is braking. The braking performance is much better than a smooth center tread or tight block pattern. WTB got this right! I live in the PNW and do almost exclusively trail, fire road and single track riding on loamy, barked or loose gravel over hardpack surfaces. If you are doing a 60% paved gravel race, there are faster on-road tires to choose from. If you are on dirt, this is the tire. Spec weights are accurate, 550g for the 44 tan wall. Easy tubeless set-up with a floor pump. As always, great prices at BTD!

I've run 9-10 different types gravel tires over the past 5 years, each one serves a specific purpose for the type of riding I'm doing at the time. But with all gravel bikes, it's all about comprimise, I want more traction on dirt but then the tires are vague and draggy on the road. They roll well on the road but not enough grip in the dirt. I finally built up a dedicated road bike so that I could focus on making my gravel bike more dirt friendly, think late 80's mtb. The 44mm Raddlers are tough as nails. I've raced these in the chunky sierra nevada mountains and ride 80% of my local MTB trails on this tire. I can still do a 50/50 road/dirt ride over 50-60 miles and feel just fine. The side knobs bite in the dirt and don't give up too much in the corners on the tarmac. Never had a problem with tire, now on my 3rd set. But again, think about what you ride and commit to the tire.

I rode 44's from Slovenia to Bulgaria, ~80% on loose limestone gravel, and they are just the ticket for loose gravel. I can climb 15 degrees, they grip well on loose steep descents, and are OK on pavement and smooth sections. They do go through tubeless fluid faster than I'd expected, and if below ~30 psi, give occasional burp flats on rough descents. But all in all, it's a great tire for rough loose gravel.

Have the 40s on 20mm inner rims, set up tubeless. They measure 38.5mm. Tires paired with 2018 Fuji Jari 1.5. The front fit is fine, rear is too tight for mud. 2-3mm of clearance between the non-drive stay. Not a problem in Colorado. ~148lbs body + ~24-40lbs bike & gear.

Awesome tread for grip on loose dirt & gravel. Not terrible on the road. Goes through sand and deep gravel nicely. Rear is too worn for climbing loose, 15+% ramps after ~2,000 mixed surface miles. Cornering still confident despite smooth-ish center. Front looks like it could last for for the full life of a second rear.

Mounting was done with a basic track pump and no cussing.

More prone to mold than two other tan wall tires I've used but it washes away with the garden hose.

For the past 2 years I have been using the wTB resolute 700x42 tires on my gravel bike and they have been great. I wanted to switch it up a little bit and try something different to give me a little bit more help on some tighter turns maintaining a bit more speed. So I decided to give the Raddler tires a shot. I will say, after reading some f the reviews I was not sure if I should still order them, but some of the reviews were so ridiculous: "Tire too loud on the road", and "Tired to think, got sidewall slashed after only one ride". Either way, I still ordered them. I have ridden around 500 miles on them now and I am pretty impressed with them. Since the ones I got are the 40mm they are a little bit skinnier than my old resolute, but I can appreciate how grippy it is. And to be honest, I can't notice a difference riding these on the road either. Overall, a good tire in my opinion.

I purchased a pair of Raddlers to replace a set of WTB Nanos, which I liked except for road noise and a "drag" feel on asphalt. The raddlers were quieter, but had the disconcerting feel of rollover onto the outer knobs on descents... not like the nanos at all!

So after struggling to get the raddlers to seat as tubeless, and then two big rides with flats on rocky sections with the raddlers that would not seal , I am switching back to the Nanos which have proved to be more durable for me.

For steeper, looser granular terrain (loose on hard as well), this is my go to. Doesn't slip easily on steep climbs, side knobs hold well on fast turns. For its width and tread pattern, it rides fairly well on pavement, but not as well as a narrower, slicker gravel tire. I ride mostly in hilly dirt that varies from hard pack to loose and rocky, hitting some double digit grades on most rides, up to 25%.

WTB tires generally are hard to seat, and I did need my Joe blow booster pump to seat it. Tight, but I was able to mount without tire levers. Seems to run a little narrower than specified. Only 42-43mm wide on 23mm internal rims at 30psi.

I purchase these when I bought a new gravel wheelset from Hunt. I had seen several videos on how difficult it was to mount tubeless tires and this was going to be my first time so I was shocked and surprised how easy it was. They seated easily with a floor pump and I have been very happy with their performance on singletrack and gravel as well as tarmac. Well worth the money in my mind and it's nice to have the peace of mind knowing it's a tubeless tire when I'm rolling on rough terrain.

I use these tires on both asphalt and gravel. Gravel will range to packed gravel to stone roads. They have preformed well and roll well. They were a little difficult to get on the rims. They sealed on the first try and hold air well. Time will tell as to how they hold up.

Love these things. They roll pretty nice on the pavement but give enough to climb a slippery clay hill on the trail. Put about 400 miles on them and so far so good!

Running tubeless. The tires popped on the rims without much trouble and sealed easily.

Switching from slicks, I expected a lot more wheel noise on the road but these tires are quiet on tarmac and give me a lot more confidence-inducing grip in the turns on tarmac and gravel.

I use the 44 on my gravel bike, Trek Checkpoint SL6, and love it. The traction and wear are very good, and it rolls smoothly. I've felt comfortable in soft and hard trail conditions. Two of my biking buddies have now added them to their gravel bikes. I'm about to install a new one on the rear.

I purchased the 700x40 tires and love them, especially this time of year when we get more rain and the gravel can be a little soft. I run the tires tubeless, and these are the best tires I have ever had for maintaining air pressure.

Like the smooth-ish center section, like the side knobs, like the width, like the looks.

Was running Resolutes, wanted something with more cornering capability.

Run these at 22psi rear, 20 psi front. I'm around 150 lb.

Had some pinhole leaks before adding sealant, no trouble since.

Love how these tires keep traction on most gravel rides. Unfortunately I have had many small pictures the first 4 gravel rides, and one that needed a plug where the small rock entered the tire. I don't have a lot of confidence that they will get me through a long remote ride without issues.

I've put about 300 miles on the Raddlers so far, and they seem to be wearing well. Running tubeless, of course, and so far no leaks. They set up easily on my Rolf Wheels with assistance from Bontrager Flash Charger floor pump. The tread on the Raddlers is a little beefier than the Riddlers (which I have previously used), and so they do better on those single track forays or looser gravel sections.

So the Raddler is a bit more aggressive than the Riddler(WTB) it appers to wear better as well.

Its performance is better on gravel and wet for grip than the riddler.

I have a preference for the Schwalbe G-One Allround but that has its issues as well!

These tires work great. They're very supple and grippy. Work great for tracklocross. Very happy with purchase.

Little difficult to seal on first attempt but overall an amazingly comfortable and forgiving ride.

Poor quality tire. If you want a bumpy ride purchase these tires.
