Tyre sizes for 100 series

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 Keith

Read my post below.

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.

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.

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!!
