Hilux 4x4 Forum

Hi Chaps does any one know what a difference fitting 285/75R16 in place of the standard 265/70/16 to give you slightly longer gearing and to drop the revs hopefully by a few 100 RPM

thanks Vidalbum

It will do, many guys do it to get a slightly lower revs, and there was an article in a magazine recently a guy claim it fuel consumption was better.

any idea of what magazine it was

You can use the differentials from the old 80 series Land Cruiser Think the one with the 3F engine

Is changing the tyres not the same thing, surely the gear ratio to power ratio is calculated according to a certain tyre size and if you change that you interfere with the gear ratio? Under certain conditions you could be putting too much torque on the gears, shafts etc.
I am only asking a question and I am not sure if it is so.

If done through a dealer no issues on warranty we've done two already and both customers are happy

SA4x4 van Feb 2015.

I know a few people that had the same scenario and all of them did a crown wheel and pinion change at N1 4x4 but i understand the warranty issue so cant comment...

thanks for all the info chaps have found some maxis A/T 285 75 16 think going to start with them

A bit off feed back for those that are interested I replaced the tyres with the 285/75/16 it has made a
big difference the truck now does 120km hours at 2600rpm and all most getting 8km to the liter on its first tank of fuel

When changing to the 285 tyres is there any other mods or does the tyres fits withhout rubbing against body or chassis.

Wim, it's a Land Cruiser not a Hilux................

no mods needed they fit with space to spare

Thanks Rory . Steve kas toe.

Fit 19'' rims with 35'' tyres problem solved
