ive purchased some new sunnys rims @ 15x7 and new rubber @ 31x10.5 to put on my 97 lux 4x4 2.8ltr diesel i have a few questions

1.) is it going to put speedo out ?

2.) hinder/worsen steering, braking, reduce speed, drivability at all ?

3.) do i have to do anything to suspension etc ? it already has 4leafs in front and 8-9 in rear and heavy duty shocks ?

appreciate your time

"surely people just aren't cruising around illegally ?? "

If you put them on without an engineering certificate you will be.

Check out the bottom of page 2 of this document.

it would be prudent to get the whl/tyres engineered/certified... if you have an accident your insurance company can just walk away from you...

from memory my lux was pretty close with 31x10.5's on it.
Just grab a gps and check it i think youll find its no further out than half the cars from the factory.

Hi Luxyboy,
The speedo on my 99 lux is spot on with 31x 10.5's.

Most Hilux speedo are fast by at least 6 %, should be spot on with 31s, BUT you will lose power, even our old 3lt v6 paj suffered in this area.

Luxy the standard way to measure height is to measure from the bottom of the rim the guard. Problem is I do not know the stadard height, but someone on the lcool forum would.

Good to hear.
This section of that document above must be out of date.

"The outside diameter of the wheel and tyre combination must be no more than 15mm over the largest diameter
wheel and tyre combination specified for the vehicle and not more than 15mm below the smallest diameter wheel
and tyre combination specified for the vehicle."
