Check your riding partners’ tyre pressures

What started out as a leisurely ride from Brisbane to Tenterfield and back over a couple of days with three friends and family turned into a bit of an adventure simply because one of our riders hadn’t checked his tyre pressures.

I have been banging on about checking your tyre pressures for years. Check out our article on correct tyre pressures here.

In the article we say:

You should check your tyre pressures every time you go out for a ride or it can result in bad handling, increased wear, fatigue cracking, increased chance of a puncture, decreased grip and lower braking performance.”

I probably should add that it is also important to check your mates’ tyres, particularly important when heading off on a longer ride over multiple days with several others.

Sadly, one of our riders had never checked his tyre pressures since he bought his bike and got his licence about eight months ago! 

We were unaware of this before our ride. In fact, I only became aware after the inevitable happened.

I had charted a course that took us over some notoriously bumpy country roads on the NSW/Queensland border ranges and recent floods in the area had made the roads even worse with plenty of unprepared potholes.

My crew didn’t hold back in criticism of the route, either.

So, as lead rider, I kept the pace down on known bumpy sections and unleashed on sections which I knew had been repaired in recent years.

With 20/20 hindsight, I should have kept the pace down everywhere.

Just south of Old Bonalbo where the Clarence Way has been resurfaced in recent years, we went through a lefthand sweeper shaded by a big old gum tree.

Right in the middle of the corner were two massive ruts in the bitumen with jagged edges. It looked like a truck had hit the skids when the tar was still hot and wet!tyre puncture pothole ruts roadworks

I didn’t see the ruts because of the shade, but as I went through I noticed I had luckily ridden right through the middle.

Not so lucky was my riding partner whose back wheel hit a rut which immediately ripped a gaping wound in the sidewall of his KTM 390 Duke’s rear tyre.

Normally if you cop a puncture it can be repaired, especially if it’s a tubeless tyre. Click here for details on how to fix punctures.

However, there is not much you can do about a 3cm tear and we were at least 50km from the nearest town.

Hours passed waiting for the RACQ/NRMA to send out a tow truck, so we never made it to Tenterfield, instead diverting to Casino overnight.

After the tyre was replaced the next morning, we fuelled up and checked our tyre pressures.

The front tyre on the KTM was 21psi when it should have been 39psi, so we assume the rear tyre may have been similarly low on pressure, causing the impact wth the pothole to split the tyre.

We all learnt a valuable lesson tat not only should you check your tyre pressures before as ride, but you probably should also check your riding partners’ tyre pressures as well!

Bridgestone Adventurecross AX41S for scramblers

The rapid rise in factory scrambler models and custom scramblers has led to a whole new category of tyre and Bridgestone has joined in with their new Battlax Adventurecross AX41S model.

Based on their Battlax Adventurecross AX41 adventure tyre, the “S” in AX41S stands for “scrambler”.

It sports a different block and tread from the AX41 and comes in wider tyre sizes.

The Japanese manufacturer says the tyre is the result of “hours behind the drawing table”.

So what is a scrambler tyre?

Basically it’s a cross between a road and dirt tyre, but with a low block, often wider dimensions and lower profiles than an adventure tyre.

It not only needs to have better dirt grip than normal road tyres, but also an attractive appearance on a road bike.

What it doesn’t need is the tough, puncture-resistant high profile of adventure tyres.

Scrambler riders often don’t head for the dirt, but also don’t turn back when the tarmac runs out.

Those scrambler riders who seek out the dirt will opt for adventure tyres and more dirt-oriented scramblers such as the Ducati’s Desert Sled and Triumph’s new Scrambler 1200 XE.

Bridgestone scrambles

The AX41S scrambler tyre adopts a single sport-touring compound on the front and a sport-touring compound in “3LC configuration” on the rear.

Bridgestone says this ensures a balance of wet and dry grip levels.

They say it has been developed for the road and make no mention of how it will go on the dirt. Although the above official photo shows a dirt road!

It looks fairly similar to other scrambler tyres on the market with a low-profile block, so it should handle smooth dirt roads quite well.

They claim the low block avoids “heel and toe wear” that is common when riding higher-block adventure tyres on the bitumen.

The AX41S should not only suit factory and custom scramblers, but also cafe racers.

Bridgestone Battlax tyres get dirtier

Bridgestone’s new Battlax Adventurecross AX41 tyres have arrived in Australia to get adventure riders dirtier, taking them further off the beaten track.

The problem with making an adventure tyre more aggressive is that it usually compromises on-road stability and shortens the life of the tyre.

The biggest destroyer of adventure tyres is the braking force that shaves the trailing edge of the block tread under hard braking on asphalt.

However, the new Battlax Adventurecross AX41 has a changed block profile and tread pattern to counter the deformation under braking, reducing wear.

That’s great news, especially for those riding heavy one-litre-plus adventure motorcycles that chew up expensive adventure tyres.

Bridgestone has also redesigned the tyre dimensions to increase the total amount of blocks on the tyre.

The Japanese manufacturer says the new tyre has a 30% increase in the cross section area compared with the previous Adventure A41.

They also claim this increases compound rigidity and strength over the A41 to “ensure the balance between durability and off-road performance”.

Bridgestone rates them as 40% on-road and 60% off-road.Battlax Adventurecross AX41
