You could consider the locally developed MIKEM suspensions too. Many of the HIlux guys swear by them and Darrell is always willing to help wherever he can. Pricing is more favourable as well.

Hi there,

I agree with all - power there is plenty of in the Patrol!! However it is a fact of life that your consumption will be effected - there is just more rubber on the road with bigger tyres - so there is more resistance that must be "moved" - but hey if you want to play better and more seriously :layrubber: you have to pay the price for it!! :blonde: However I don't think it is any worth slicing your wrists about!!! :chainsaw: :lol:

Hi all, pse explain to me one thing re bigger tyres.
Why do you guys in all the post about tyres want to go wider or fatter?
Whats the thinking behind it?
For and against of wider vs thinner?
If its for sand, no way its the driver and tyre pressure

I want to go thinner but higher, like 235/85/16, I always like this size on a 4x4 , had them om all my previous 4x4,s.Its also available all over Southern Africa, in the smallest of tyre outlets you will find one.
Its only my current GU that I havnt fitted with this size, will it fit on the standard GRX rim ?

Koos, I agree absolutely that one should rather aim for higher aspect ratio (i.e. taller and narrower) tyres. This allows for a large footprint area when deflating for sand driving, but the key is that this footprint is long and relatively narrow and therefore does not have to push a wide wall of sand out the way in front of it as a wider tyre would.

The problem with fitting 235/85R16 tyres to the standard Patrol rims is that the rims are wider than the maximum recommended width for these tyres. The 8JJ-16 Patrol rims are 8" wide, because they are designed for 265/70R16 or 275/70R16 tyres, while BFG states, for instance, that its 235/85R16 AT KO tyre may only be fitted to rims of 6" to 7" wide. This is why I went for the 285/75R16 size. This tyre is not overly wide and the 8" rim is in the middle of the allowable rim widths for this tyre. It also is a 32.8" tyre so that maximizes the height of the sidewall to enable deflating to relatively low pressures for sand. The 235/85R16 is a 31.7" tyre.

If you have 2 sets of tyres (AT& MT), what is the correct way of storing a set of tyres. I remember years ago I read somewhere there is DO'S AND DONT'S, but cannot remember.

Hi Guys,
Is anyone running bigger tyres on a 3.0TD hand grenade?
I reckon the 285/70/16 will be too big (not enough power at pull off). Considering a 5% increase to 265/75/16. More side wall, 1" bigger diameter than my currrent 265/70/16 Bridgestone 694's.
Also, not happy with the Bridgestones - too many punctures, poor milage (40,000kms and they are smooth) Considering Hankook Dynapro ATM's or Michelin ATX. Anyone have any experience of these?
Other option is BFG AT's but had them on my Landy and had constant sidewall failures...
