Does anyone know if you can fit 285 x 33 inch tyres on a standard 100 series Landcruiser with IFS without doing a
suspension lift?

Hi Laurie,
I am wondering about Cooper SST Max. I have standard 8 inch x 16 inch Landcruiser mag wheels.
The tyre size is 285.75/R16
Stated suitable rim size is 7.5-9 inches
Outside diameter is 840 mm compared with about 813 for the original tyres.
They are ten ply with a 126Q rating and I am thinking of fitting them to both vehicle and heavy off road trailer.
Just wondering if they would foul the bodywork. I hear 285s are OK but am wondering about the extra inch in diameter.

I notice you have some dimensions in mm.
Do ya self a favour....stop talking about widths and diemeters in inches.
the regs are all in mm and even the tyres designated in inches are not that size...31s arent 31 inches..that are 30 1/2 even on traction tread.
I doubt that you will have problems with the extra 25mm.....others may conform or deny......but you would be wise to reset your steering stops.
Ask ya self whay you need bigger tyres and think how much advantage it is going to give you.
Realy 25mm extra diameter....12.5mm extra height in theory.....then they get weight on them and you air them down off road....so what are ya going to achieve..an extra 8 or 10mm tops off road...is it realy worth it.
cheers

Hi my first 100 series turbo I fitted 285R75/16 tyres and regretted it, made fuel economy worst and the steering worst ,looked good !and i think you will find they are illegal to fit, 15mm rule, I have the new cooper ST maxx on my silverado 285R75/17 they are noisey , appear to be one tough tyre but the jurry is out until I make them work then I will comment as Iam not a fan of coopers tyres and will give them the benefit of the doubt for now as they ticked all the boxes for the tyre I was looking for except for the noise!!

Mate most states ( including QLD) that used to run the 15mm rule have now signed up to VSB14 and now permit a 50mm diameter increase and a 50mm
suspension lift without inspection or engineering.

We have a V8 100 series fitted with 285/75/16 BGFs and they are fine.
Used to have pro com 305/75/16.

2005 GLX 100 4.2td. Front torsion bars wound up to highest safe height. Maybe about a 1" rise - not measured. The 285/75/16 Cooper ST Maxxs fit nicely. Haven't noticed any great increase in fuel consumption other than what would be expected with a larger diameter tyre. Steering is fine. The power steering overcomes any shortfall with ease.
If you are local in
Canberra you can try mine. I have two complete sets of rims with tyres.

33s fit ok. Check lcool for more detail.
I have an IFS 100 with stock
suspension and running 285/70R17 (same size as a 285/75R16) with no problems. The 285/75R16 is a very common size.

Thanks everyone for the advice. I do appreciate it. Might steer clear of the muddies and go for the AT's.

I run Coopers and next choice will probably be BFG A/T in that size. The Coopers I currently have fitted developed radial cracks in the sidewall after very few rotations. The previous set failed to maintain interest in keeping its lugs on. Now just too time poor to chase them up on warranty and all the challenge that goes with it. That's my two bob's worth!!
