Thread: 285/75/16's on a D1

mat,
me new ute has the 90's tyres and rims on it, 285's on 7'' rims with an 86mm back space. cant comment on what touches at the rear as its a ute...but for the front its only the inside edge of the pass side front well that just rubs. i also have the OE flares fitted and the tyres are inline, just, with them.

its the rear thats going to be the issue.

i have an air hacksaw and a plsma cutter

cheers phil

Discovery I will need a 2” body lift kit and will probably need to fit flares. offset of -25 mm will do it for the 16x8 Rims

I've seen 33" on Disco 1's without a Body lift but there is some scrubing on Full Flex with flares fitted

what about a 255/85/16? would fit nice on a 7" rim

Hi Phil, do you reckon the issue would be rubbing on the doors or the back of the wheel arch? I dont mind cutting more from the back of the wheel arches but its obviously more difficult to cut it from near the doors.

The tyres will definitely need doing so maybe i will go with 265/75/16's for now and get the lift, flares etc sorted so the next time i need new tyres i can fit the 33's.

What is the rolling diameter of the 255's?

Boxer fitted 285/75/16's under just a 2'' coil lift
Don't quote me on this but i think 255's measure around about 33.3''s

Ok, did some looking around, the 255's are about the same diameter as the 285's but obviously they are 30mm less in width. Would this be enough with a 2in suspension lift and trimmed gaurds on a D1 or am i better running with the 265/75/16's for now until i can sort the lift and flares etc?

In the end the 265's are only 30mm less diameter so going the 285 or the 255 only gives 15mm more in ground clearance diff wise, and the 255 isnt as wide.

Quick calc show that the tallest tyre out of the lot mentioned is the 255 85 at 33" folowed by the 285 75 at 32.8" then 235 85 at 31.7" and last is the 265 75 at 31.6". In otherwords not much between 285/75 and 255/85 at around 33" and the 265/75 and 235/85 at a bit over 31.5"

When I fitted 255/85R16 on my 3 door disco with no body lift, I needed to do a fair bit of cutting.

At the rear :
Cut rear of guard.
Cut top of sheetmetal that hold mudflaps. Rebend to push crease line further back.
Guard lip need to be bent up or it will catch on edge of tyre.
Trim all bolts flush as it will rub the top of the wheel arch.

At the front :
Cut rear of guard and maybe end of sill. (sill depends on quality of build, they all vary)
