Discovery Series II

• 255/65-16: Stock tire size.
• 255/70-16: Just a bit taller than stock.
• 265/75-16: Taller and wider than stock, possible to fit without lift. minor rubbing. Looks real balanced with mild OME lift.
• 285/75-16: even taller than 265/75-16, r requires a bit more lift than the regular OME lift. some have fitted OME751 from Discovery series I, and changed SLS sensor in the rear to achieve almost 3 inches. Gearing and shaft strenght become issues.
• 255/85-16: a bit taller than 285/75-15 but narrower. Gearing and shaft strenght become issues.



Ok so when it comes to "mechanics" i know basically nothing so what i was wondering is; exactly what shaft are they reffering to? Can you upgrade it to stronger/performance shaft?

Also gearing becomes an issue.. Is there anyway to change the gearing so it would drive normal/less strain? Will bigger tyres put more strain on my automatic gearbox? Should i just stick to normal size tyres?

I dont mind paying the extra money to get stronger components etc if thats what it comes down to.

The shaft is the axle half shaft that runs between the diff and the wheel hub. I've been running 285/75-16 for years and to break the axle then you're doing something silly. You can run heavy duty half shafts but if you do this then you probably should fit an aftermarket diff also as the standard diff isn't much different in strength compared to the standard axle.

Unless you regear, the tyres do add additional strain to the gearbox etc, but the power which a standard engine produces is well within the capacity of the gearbox.

What do the 285s equate to in inch sizes? like a 31"?

• 255/65-16: Stock tire size. - On an 8" rim !

• 255/70-16: Just a bit taller than stock. - That's what I'm running. Speedo under-reads by about 4% .... so approx', 95km/hr on speedo = 100km/hr gound speed.

Mine is a 2004 Td5 Auto - This size tyre works well. Stands 30" high instead of the standard 29".
