27.5 road tire: the perfect balance for urban and road riding with a MTB

The 27.5-inch tire in 1.75 width is becoming increasingly popular among cyclists who ride their mountain bike (MTB) on paved roads. Not too wide, not too narrow, it offers an ideal balance of comfort, performance, and versatility. If you're looking for a reliable MTB road tire, here's why this size is worth considering.

A size designed for versatility

The 27.5 road tire, also known as 650B, was originally designed for off-road use. But thanks to its diameter, it's also very well-suited to city commuting and road riding. At 1.75 inches wide (roughly 44 mm), it's narrower than a typical MTB tire (usually 2.0 or 2.25), which helps reduce rolling resistance and improves speed and smoothness on asphalt.

It’s the ideal choice for mixed-use: commuting, fitness rides, and even sporty touring on hard-packed trails and tarmac.

Key features of a 27.5 x 1.75 road tire

Here are the most important technical specs to consider:

• Diameter: 27.5 inches (ETRTO 584 mm), a modern MTB standard

• Width: 1.75 inches – a mid-range width offering great performance without sacrificing comfort

• Tread pattern: often semi-slick or low-profile knobs, providing good traction on pavement while maintaining minimal grip on light trails

• Recommended pressure: higher than off-road tires, reducing deformation and improving speed

• Weight: generally lighter than wider MTB tires, contributing to better handling

Benefits of using a road-oriented tire on your MTB

Switching to a 27.5 road tire on your MTB gives you:

• Improved pedaling efficiency on hard surfaces

• Less noise and fewer vibrations

• Slower wear on asphalt compared to knobby tires

• A stable ride even at higher speeds

• A great compromise between comfort and performance

Unlike aggressive mountain bike tires built for mud, roots, and loose terrain, a 1.75 tire features a center tread optimized for pavement, often with directional grooves to channel water and maintain grip in wet conditions.

Who is this tire for ?

The 27.5 road tire is a smart pick for:

• Urban riders who mainly use their MTB on roads or bike paths

• Leisure and touring cyclists looking for more efficient rides

• Riders wanting to convert their MTB into a light gravel or hybrid bike

• Cyclists who want a comfortable, reliable alternative to skinny road tires

In summary

The 27.5 x 1.75 road tire is the perfect solution for anyone using a mountain bike on paved surfaces. It combines versatility, durability, and smooth rolling, while still retaining the essential strengths of an MTB tire: strength, traction, and shock absorption. A smart upgrade for riders seeking urban performance without giving up their MTB's off-road soul.
