Outer Limits 4x4 Board

Looking at getting a set of simex 35's ET's just after some feed back on the 2 different widths 11.5 and the 12.5.

most of the winch guys seam to run the 11.5 and some 10.5 I'm guessing cause they dig better in greasy conditions?

I have a LWB GQ which is quite a heavy unit,is the 12.5 better suited as a all rounder on a heavy vehicle?would be better on soft surfaces pea gravel/sand etc less likly to sink/dig there way to china

Does the 12.5 drive better on road?do they last any longer being tripple block?

Thanks for any advice

Do a search, it's been mentioned on here before i'm sure.

I run the 11.5's and they're groulse. From memory there was a few comments made about the third centre row actually reducing the tyres self-cleaning effectiveness and handling more like a std mud terrain on rocks and in mud.

Flame suit off so go for your lives if i'm wrong

wider is quieter onroad, has more tread on the ground so offers mor traction, can 'float' across mud more easily with momentum.

narrower tracks easier onroad and has lighter steering (hardly noticable after a cpl days driving), digs down more in mud to bite into harder stuff underneath.



my pref is for wider, but its down to personal more than not

I run the 12.5 and love them on a lwb gq. It comes down to personal choice.

i have found the wider the better.
cant coment on simex personally as i have never owned a set yet bu a few mates have and they all have 12.5

How long is a piece of string? The 12.5's don't work in NZ which is why almost all comp trucks are using 11.5 or 10.5. If dry then I would think the 12.5 would be better, but I've only used 11.5 and 10.5.

Why does everyone ask this question? It is twice the distance of the measurement from the centre to one end.

I have had both on my GQ LWB and prefer the 12.5. Drives better allround.

Faster out of corner, much nicer on road. Can't tell the difference in the mud but everywhere else is much better suited to the heavy GQ.

I'm going to price up the 35/12.5/15 see how much more than the 11.5 they are.
Going by tyre web site the 35/12.5 is only 3-4mm smaller than the 36/12.5 which would keep me in 33-35" class in club events,no point being top class with a gutless big tank

Cheers for input guys

i have the 35x10.5r15s and have been happy with them, im not really into mud though, ive used them more on rocks and loose shaly stuff, ive run them in a few comps and they have worked pretty well for me,

So the tyre size isn't done on actual size? Sounds like a pretty unfair way of measuring something. A 35x11.5 Simex is 35.5" and a 35x10.5 is 34.9. Most competition rules require tyres to fit through a gauge to qualify. ie Winch Challenge rules is 36.5x13.5 and a 36x13.5 Swamper Irok will fit if on 7" wheels.
