Anyone got 35' tyres on a gu patrol (or 315/75/16). Would like to know two things. 1)Do they rub at any point during
suspension articulation and 2)Is there a noticeable drop in performance onroad or increase in fuel consumption. Does the engine struggle on takeoff? (TD42T). For info I currently run 33' (265/75/16) tyres.
Thanks
Rick.

G'day Rick,
Mate, 35's can come in a number of widths, 35 x 12.5 or 315/75/16. being the more popular
The width in combination with the height, then depending on the flex u get from your
suspension will determine when and if you scrub out.
35 x 10.5's ( or even 285/85/16's) should cram in there with about a 3 inch lift. Ideally tou need about 6 inches spring plus 1 inch body for a decent amount of flex, and the 35's to fit in. 35 x 12.5's , may foul against the rear of the front flare when the tyre is turned under load.
Or.. you could get some super stiff springs and shocks - no
suspension travel, terrible ride, but no scrubbing out.
I run a 5 inch lift, and with 35 x 10.5's it only scrubs at full articulation. Doesnt bother me.
As for performance, sure it drops, but the turbo has enough torque to push it. Depends what your idea of acceptable performance is. My gu is not turbo, and while its a bit sluggish - its still ok. its a 4x4 not a race car. Tyres with a reduced rolling resistance like the Goodyear MTR will reduce the effort for the car, whereas super swampers will be harder to push.
Fuel consumption.... i dont know. I get about 12l/100km from non-turbo.
check also the differences in ACTUAL diameters. eg Goodyear MTR's 35's are actually 33.8 inches (from memory) and Simex 34's are actually 35.2.......... good marketing hey !

Thanks Troy,
for info I have a 2 inch lift (measured its actually about 75mm = 3 inches) but officially its 2 inches. Is 285/85/16 available in common 4x4 tyres? I have 285/75 as I said and have never seen the 285/85 size but im interested in it as that would be about 34 inch tyre. Have another question for you! What will be the result to my articulation if I remove my sway bars (offroad only of course-I know that onroad I would experience rocking and wander etc) and what stops the spring from popping out? Is full travel just limited by shock absorber travel, and will this damage my shocks. Should I just lengthen (more) the sway bar links to improve articulation? (the rears are lengthened but not the front) I run OME 2 inch lift (with a 2cm spacer at the front end only) and Rancho 9000's. Thanks mate.

G'day Rick.
Mate, do u have an off list email address ?? may be best rather than take up heaps of space here, and make the posts hard to read as its a "lengthy" subject.
