VX30 vs M5B EVO: Which One Came Out On Top?

Choosing the right front tire is one of the most important decisions any hard enduro rider can make. The front tire is your direct connection to the terrain and can make or break your ability to tackle technical sections.

With so many options on the market, deciding which tire will perform best for your unique riding style and local conditions can be tricky.

In this comprehensive guide, I’ll share my personal experience testing and comparing the latest and greatest hard enduro front tires to help you determine the ideal tire for your needs.

Specifically, we’ll take an in-depth look at the IRC M5B Evo and the IRC VX30 front tires – two of the top contenders in the hard enduro tire game right now.

My Top Pick for Most Riders

Before diving into the details, let me provide a quick answer for those looking for fast facts. Based on extensive testing on harsh terrain ranging from steep, loose hills to slick riverbeds, I’ve developed a strong preference for the IRC M5B Evo as my front tire of choice.

Here’s why in a nutshell:

• The M5B’s slightly softer compound and more flexible carcass provide exceptional grip and control, especially at slow speeds
• The thinner profile gives me more precise steering and inspires confidence when side-hilling or picking my way down technical sections
• Overall, the M5B’s characteristics align perfectly with my hard enduro riding style which focuses on low-speed, high-traction scenarios

However, there are certain situations where the IRC VX30 may be a better option, which I’ll explore throughout this guide.

The VX30’s stiffer construction makes it more stable at high speeds, and a wider profile offers straight-line confidence. So for riders who favor wide open tracks or faster speeds, the VX30 gets the nod.

The choice ultimately comes down to your unique riding style and preferences. By taking you through an interactive journey to compare these tires, my goal is to equip you with the knowledge to make the best decision for your needs. So let’s dig in!

An Interactive Journey Comparing the M5B Evo and VX30

Size and Construction

The first difference you’ll notice between the M5B Evo and VX30 is the width – the VX30 has a visibly wider profile on the rim. Both tires are technically 80mm (labeled “8100”), so why the discrepancy?

It mainly comes down to the fact that sizes vary across brands and models based on the target performance characteristics. The numbers are more guidelines than absolute rules. Here are some key reasons why:

• Flexibility matters: A tire with a softer compound or more flexible casing necessarily gets more grip from a given profile width. The M5B Evo flexes more than the VX30, so it can achieve optimal grip in a narrower package.
• Performance requires customization: Every tire is tuned for specific attributes. A one-size-fits-all approach would restrict performance optimization.
• ** Guidelines bring options:** Having flexibility in sizing gives riders more choices to match different riding styles. Wider is not inherently better.

So rather than getting caught up on size as an absolute metric, focus on the performance you want. A thinner tire like the M5B Evo can deliver increased steering precision and side hill control by design – the numbers on the sidewall only tell part of the story.

Compound and Casing

These performance attributes we’ve been discussing come down to the rubber compound and casing construction of a tire. This is where the biggest differences between the M5B Evo and VX30 emerge:

M5B Evo

• Softer compound = more grip and conformability
• More flexible casing = increased contact patch and traction

VX30

• Stiffer compound = less deformation and more stability at speed
• Firmer casing = better high-speed cornering and predictability

I found the M5B’s softer characteristics better suited to my typical riding scenarios – low-speed technical sections requiring maximum grip. The tire flowed over obstacles and stuck to off-camber sidehills with control.

On the other hand, the VX30 inspired confidence when pushing the pace on faster trails. The tire felt planted in sweeping corners and offered more feedback at speed.

So, in summary:

M5B Evo = optimized for tech; thrives on traction

VX30 = optimized for speed; thrives on stability

Choose the tire that aligns with the majority of your riding. For me, technical prowess wins out over all-out speed most times. But your needs may differ.

Riding Experience and Feel

Nothing beats getting personal saddle time on a tire to understand how it truly performs. Here’s a bit more subjective insight on how the M5B Evo and VX30 feel out on the trails:

M5B Evo: From the first turn of the wheel, I noticed the M5B’s thinner profile. It has very quick steering – easy to change direction but still stable.

It digs into the terrain with authority on sidehills and carves a controlled line. The soft compound absorbs small rocks and edges that can deflect a firmer tire. It feels like an extension of my intentions with incredibly precise control.

VX30: With the VX30, the first thing I noticed was the wider footprint. It has a planted, stiff feeling at all points of lean.

The tread blocks give continuous feedback on soil conditions and available traction. It rides like it’s on rails at speed in corners, resisting deflection and squirming.

However, the stiff characteristics also reduce outright grip in low traction situations compared to the M5B.

So in many ways, it comes down to grip vs. stability – choose the tendency that matches your riding style and preferences.

I favor the M5B’s unparalleled grip and traction for technical riding. But I can’t deny the VX30 is confidence-inspiring at a race pace.

Try them both yourself if possible, and pay attention to subtle differences in feel and control. Small nuances can have a big impact once you hit the trails.

Key Takeaways: Choosing Between the M5B Evo and VX30

Here are some key pointers to guide your decision between these two outstanding tires:

• For technical riding and max traction: M5B Evo
• For speed and stability: VX30
• For precision steering and sidehills: M5B Evo
• For high-speed cornering: VX30
• For soft terrain and grip: M5B Evo
• For hardpack and predictability: VX30
