First Impressions: Teravail Rampart Tires

With a name like Rampart, you might get the impression that Teravail’s all-road tire is a sluggish, heavily armored utility model. While Teravail does offer the 650B x 47 road-plus tire in durable casing ($65 MSRP) and light-and-supple ($55 MSRP) versions, the company’s race-bred Rampart is really more at home exploring uncharted backroads, both paved an unpaved.

In addition to the aforementioned road-plus (650B x 47) size, the Rampart is available in 700 x 28 and 32 sizes. Each size comes in durable or light/supple versions, but you’ll only find the tan sidewalls ($60 MSRP) on the 650B x 47 light/supple model that I tested. The 650B x 47 durable and supple versions have claimed average weights of 550 and 510 grams, respectively, with my light-and-supple review samples coming in at 495 and 497 grams.

Installing the Ramparts couldn’t have been easier. Straight out of the box, I was able to seat the Tervails with just a floor pump (well below their 40 psi minimum pressure). Mounted on Zipp 303 Firecrest carbon rims (21 mm internal width), my sample tires measured 46.7 millimeters wide at 70 psi (casing-to-casing). Teravail’s recommended (internal) rim width is 23 mm, but I didn’t encounter any problems due to my test bike’s narrower rims. When installed on PUB’s Gravel 734 wheelset, the Ramparts’ casings plumped out to over 48 millimeters, giving the tires a decidedly u-shaped profile.

Every one of Teravail’s tires–whether they be dirt, gravel, or road models–are tubeless compatible. I was expecting that the Ramparts’ light-and-supple sidewalls would require additional sealant to compensate for weeping, but that was never an issue during my testing. And even when inflated well below the recommended minimum 40 psi, I never experienced any burping with either of the aforementioned wheelsets. The Teravails’ tubeless performance was so good, in fact, that I never even considered using them with inner tubes.

When it comes to tire pressure, I generally take manufacturers’ recommendations with a healthy grain of salt, and the Ramparts were no exception. For dirt and gravel riding, I found that 23-25 psi front and 28-30 rear psi worked well for my (200-pound) weight. For paved-road use, I’d inflate the Ramparts to 30 psi front and 35 psi rear. I might bump up the pressure a few psi when carrying a load, but I rarely felt the need to inflate the Ramparts above Teravail’s recommended minimum 40 psi. Ideal pressure will surely vary with terrain, rider and bike weight, but the Ramparts’ sweet spot isn’t so narrow that it requires topping off before every ride.

Much of of the Ramparts’ testing took place on my 12-mile, mixed surface commute. More than a few times, I found myself riding home after a late-afternoon storm. Those types of conditions often result in increased punctures, but I’m happy to report that the Ramparts have remained flat-free (although part of the credit can be attributed to the efficacy of Orange Seal‘s tubeless sealant). Cornering and braking on wet pavement exceeded my expectations, and off-road traction only suffered in deep, loose gravel (which is something I’ve experienced with other, similarly sized tires using road-style tread patterns).

If you’re looking for a supple, tubeless all-road tire, Teravail’s Rampart should be on your short list. Nimble and quiet on pavement, the tires’ high-volume casings deliver a smooth, comfortable ride on dirt and gravel. After two months use, my samples show only minimal tread wear, and the light-and-supple casings haven’t suffered any cuts or scuffs.

  1. I haven’t been able to find much on these so I thought I’d toss my two cents out… I bought a set of Velocity Blunt SS wheels from a buddy who had been running the Ramparts on them for a few months. He left them on and I’ve done a couple hundred miles in them, probably 95% gravel (dirt roads in MI) including some wet conditions. I have to say I was a bit nervous when the forecast called for rain during last weekend’s race but these things performed flawlessly!
