I'm surprised I haven't seen any chat about these yet:



https://acceleratire.com/tires/badak-x-treme/

31 10.5 15 or 35 10.5 16

Speed and load rated
Load range C (yes! a 16" tyre with a C load rating )

The 31 is 31.4" tall, the 35 is 35.6" tall. (US reviews are confirming this - not like some tyres where the 37" tyres were 35" tall *cough* boggers *cough*)

Yes, 16" rims are a bit of a pain, but they would probably squeeze onto a XL-7 rim.

The 35 weighs 32kg, so they aren't light, but there's a lot of rubber there.
Apparently there's grooving advice on the Indonesian Accelera site.

They look like axle killers.

Wonder if they balance up at all?

[Gwagensteve]

I don't know. The guy with a set on Pirate hasn't balanced them yet, but he's going to see how much lead it takes. He claims he'll probably use beads or similar.

I'm in two minds about whether they're axle killers or not. They're narrow, so that's a huge advantage, but they're fairly heavy.

I'm sort of falling out of love with super aggressive tyres - the performance of the 35 10.5 Baja KR2's proves it's not necessary to have all those lugs to generate traction, but I'm always interested in something that will work on or slick clay climbs. Pretty much every tyre sucks on them, and the key is very high ground pressure, conversely, these tracks are full of massive ruts so while a 215 75 generates loads of grip through high ground pressure, you're stuck on the diffs.

[Fatzook]

Yeah its a very specific condition where a tyre like this excels. Just like the old simex treps used to dominate the Malaysian rainforest challenge because it was soupy bogs and mud climbs. But fore everything else they needed to be siped to within an inch of their life to be usable.

They may be well suited to the Vic high country though. I've never had the pleasure of driving down there despite several attempts.

[Gwagensteve]

There's a myth that the high country requires aggressive tyres and highly built cars. There are very few tracks in the high country you can't drive in a factory stock 4WD. A few would be a bit sketchy in the wet, but that's mostly because the people driving them are in grey nomad expresses that weigh 5 tonnes and they have 50psi in the tyres.

The stuff we build cars for is all within about 100km of Melbourne - it's not the high county, and it's challenging because it gets lots of traffic, lots of dirt bikes and lots of erosion. TBH there's literally a handful of tracks that are properly challenging to a Sierra on 35's and they're not very well known out of a relatively small group. Even then, they're close to drivable for a Sierra on 31's, it's just the bigger tyred cars do it easier and with more flair.

The problem is when it's wet the erosion demands maximum ground clearance because you can't stay out of the ruts and conversely the slick clay requires maximum ground pressure. That's not an easy combination to find a tyre for and it's even harder when we also want a light tyre that's exceptionally flexible. There's lots of talk of the larger SXS tyres being the right answer but the lack of any sort of pretence of road legality is a problem for many people, same for the class 10 off road race tyres like the 35 10.5 Tensor and BFG KR2. Even though these aren't aggressive, they're soft and conformable which means they generate amazing traction.

I've been very happy with my Krawlers but they definitely don't generate enough ground pressure for slick climbs in winter. They're comfortably outperformed by a 9/34 swamper.

Shows how much I know about the Vic high country

[Gwagensteve]

It's scenic, historic and awesome for camping, and it can be steep, but it's not technical driving. It's too well maintained. The sketchy tracks were all closed 20 years ago, or realigned. People do get in trouble up there, but it's normally through lack of preparation or experience. (i.e the grey nomad expresses)

Our club pretty regularly run trips into the high country to drive the iconic tracks, the trip leader is in a Jimny on 215's.

Im sure I seen a test run video of these the other day on fb

[zook ute]

I'm going to need tyres for the ute when I get it going, but think I'll stick to the 9/34 swamper.

[MUD-PIG]

Bit of a grave dig, but even after being out a while. Still finding it hard to get a set in Australia. Well Darwin more so.

Anymore word on how these run?

[Sausager]

There are plenty of these here in NZ. They are incredible in the mud - of which we have a lot here. They are a decently soft compound, and 35s bag well on a mates ~1700kg buggy.

I haven't owned a set, but my mate raves about them. I would say they are better than a simex in the slop, and they are better on the dry stuff too being a softer compound.

[Gwagensteve]

Joshyboy26 runs these on his Ute. He’s fairly happy with them apparently compared to the Q78 swampers he was running) but I recall him saying they lack lateral grip, which was also a problem with TSL boggers in technical terrain I believe.
