I'm looking at some new 31x10.5r15's for the zuk and considering these - anyone got feedback/info on them?

Particularly:
Sidewall strength
Do they cut/chip
Noise on road
Tread wear/rubber hardness
On-road behaviour (wet/dry)
Offroad behaviour (clay/mud to rock/dusty rocks)

I had these for offroad work on my Rocky

Aired them down to about 5psi without beadlocks and loved them. Awesome in mud/clay. Good enough on rocks imo. Tread wear on tarmac would be horrific I'd imagine, but I hardly ever ran mine on road. When I did, they where noisy as hell and the car slowly drifted side to side, definately not a daily tyre.

Hrm thats odd - im coming from cooper STTs (new type) - theyre a brilliant tyre, however clog up way too much in mud for my liking. I would have thought the centipede would be better in that situation and not much worse on road with the centre contact patch they have?

I run these in a 36.

On Road, they are fine i think, in the Dry they are no worse than any other tyre i've run.

Wet Roads, if you remember there on they are fine as well, there better than my worn MTR's .

Off road they are Awsome , with what i drive i don't think there is a better tyre out, expept maybe Trep's .

I know a mate has trouble with understeering with them on(36), but on my Mav there is no issue, the only thing i've found is that the first couple of K's, are like sitting in a massage chair until they go round again

driving a zuk practically requires a kidney belt anyway =) its like the massage machine was set to "kill".

How do you find them in the mud compared to the MTR?

extreme trekker and extreme tekker 2's are sightly different 3 rib instead or 2 rib. so arent they classed as 2 different tyres

the set i had they are only good in mud.

Simex Centipede's don't grip so well on rock. They are quite good in the sticky stuff.

Yes they chip and tear as all tyres will when abused.

Swampers are a pretty good all rounder, the Trepadores would be good if they had side lugs in the smaller sizes.

No comparison, Simex all the way

I would not buy MTR's they came on the car, and from what i've hear MTR's are near on the same price as the Pedes

Misread

I've got 35 inch simex centerpede's and they r great on mud and clay had them on rock also and they worked well, as for on road use I've used them in wet and dry conditios and in the wet they can get slippery in dry not so bad. As for dropping the pressure went to 8 psi once and they kept popping off the rim but that had something to do with the fact I run 7inch rims, apart from that they r the best tyre I've had so far

has anyone driven on the same size cooper STT to Simex ET so i can have a direct comparison between brands? That'd be fully sick.

I really don't see how the two can compare?

One is a good all round tyre, commonly used for touring. The other, is a very aggressive tyre that performs great in mud and is commonly used in competition.

Exackery. No comparison between a Radial and Bias Tyre.

oh, no of course, just wondering if anyone else has made the swap thats all... im pretty much dead keen on a set now anyways, but it would be interesting to see what the reactions are by direct comparison.

i've noticed the pedes dont have siping on the tyres though, so perhaps that explains why theyre a bit squirrelly in the wet on road =)

if you drive mainly rock or creek beds then i would be giveing these a miss.

They are however, obviously excellent, and well proven in the loose stuff and mud.

I have a direct comparison CavemanGQ above has identical car to mine, same suspension, same turbo cars built at same time in same way, on my old coopers I would spin 2nd and 3rd at 5000-6000 rpm to climb super steep clay tracks, he could drive up the same patch in first with no boost and no wheel spin as they don't fill with mud and clay at all, on shale and gravel no big difference, on rock the simex just grav onto edges and pull over the coopers at 10psi and lower are not that great.

Thanks guys =)

I rarely let my coopers down (run them at 20psi for contact patch) - i found letting them down offroad doesnt give me as much bite in mud etc, and they chip out much more on rock when aired down.

I look forward to buying and testing how the pedes react to my abuse!

My 35X11.5 are leaking through the sidewalls in several places on all tyres. We're pretty sure the cause is beadlocked tyres, with low pressure a alot of hp twisting the side walls and causing them to come a part a bit. It isn't a big deal and if i had tubes then no problem. The obly real solution is a radial tyre and there aren't any that compare.
See below for waht I mean about twisting the sidewall.


It is also a testament to the grip the tyre has though.

I have 35x10.5x15 Simex on my Range Rover.
Nice tyre for offroad but nothing for onroad.

Never had a louder tyre on the road. It is not only a little tyre sound.
And my tyres are at ~40% after <2000km. That is EXPENSIVE!

If you use them only for offroad - it is a very nice tyre with one exception - there are hopeless on wet rocks.

My 2c

They have a new size now 35x12.5 16

Got a set of 35x10.5x16 For the Cruiser.

Would never drive them on road unless it is between tracks or short bursts from the camp area into suburbia. The noise is unbelievable, kinda like those propeller powered planes from WW2.

In the mud, they are brilliant. Give them a quick wheel spin and it will clear out the lugs in no time. Mind you, you will be getting brick sized chunks of mud/clay thrown around the place. Air them down and go through the mud, they will work wonders. As for rocks, not too bad. They arent a sticky compound but if you let enough air out of them then they aren't so bad.

PUT TUBES IN. As far as sidewall strength goes, they aren't really special. With tubeless tyres, we were getting punctures pretty often. Get some simex tubes and voila, problemo solvered

Bloody useless on the sand (mind you this is coming from a loaded 105 cruiser of 10.5 wide tyres )

As far as onroad behaviour goes, they grip well and if you can get over the noise, they behave pretty well. If loaded up with mud though, it wwill feel like your car is trying to pull you off the road.

We got our 4 tyres second hand with about 90% tread for $550 so no complaints for us.

As a second set, brilliant.

I've had copper stt's in 33's , simex ET2's in 35x10.5 and mtr's in 32's/35'sand I have to agree with the above with the extra info of IMOP I prefer coopers. Fair enough coopers clog up a bit but the handle good in all other surfaces (Alot better then MTR's) but for a road driven truck the simex's are stupidly loud.

Like others I thought they weren't real good on wet rocks/wet tar but ok when dry.

My simex's were radials and chipped/ cut up really bad and were almost impossible to balance, they tend to walk around a bit on road too but more so when tread gets lower.

Me personally it's either coopers stt's or maxxis treps in radials for next set of tyres.
