Hi everyone it is time to buy new tyres for the GU patrol. I have been running 265/70/16 on my patrol to this day. The truck has a 2 inch lift and with standard size rubber it looks like it is running on skateboard wheels. The speedo when compared with a GPS is out also, GPS 104kmh Patrol 110kmh. I am going to at least put on 265/75/16 but would love to put 285/75/16 on. Is there a problem with a 285/75/16 on the patrols rear door, does it add too much weight and do I need blocks or packing to get this size tyre to fit. Maybe I can convince the other half to let me buy a dual wheel carrier.

you can get a spare wheel spacer from Kaymar for around $80 which also doubles as a
camp light carrier. The cheaper option is to get the spare wheel bracket off a Ti model as it is spaced out further.

Hi Leroy I suppose the above price does not include the
camp light. Does it add too much weight on door, I have fridge in back and open the rear doors often.I think I will go the 285/75/16 the extra lift would be wonderfull.

The bracket weigh's buggerall. But then the 285x75 prob weigh's a little more than the 265's! I have 285x75 BFG muds with the spacer as do other friends. You can make up the
camp light pole yourself. Need some sqaure tube (can't remember the size but was appro 15-20mm square) and weld a little plate on top and buy a small spot light to mount on top and a lock nut.

Its touch and go Joe
Some just fit but many need to space it out just a little, the actual size is ok and I regularly carry the slightly larger diameter 255/85/16 - however the problem is more with the wheel offset. Standard Nissan 16X8s can just interfere as they don't quite hold wheel out far enough.
I use narrower , but better offset 16X7 steel Trak 11 wheels here they always provide enough clearance - at least they better as I have ordered a 4th set of wheels with 255/85/16 Bighorns for
easter. (Imho 285 is to wide for long life of patrol front
suspension).
I also have Aluminium spacers plates made for my wheels as one of my aftermarket wheel sets is not offset and I carry these plates on the car by placing them over the spare wheels studs. This has the effect of spacing spare out another 12mm

how does the width of a tyre (285's for example) impact on the longevity of the front
suspension on a Patrol?

Hi Leroy
The 285 size problem begins with requiring an 8 inch rim (as opposed to standard car which comes with 6-8inch but needs only 7 max) and the tyre weighs more as
well , typical total unsprung weight increase is around 6kg or 15% but can be more.
As
well as the
suspension having to work with increased unsprung weight the tyre section is typically 30mm wider which puts increased load on the outside edge of the rim particularly under cornering, and leaves a wider wake making it a little harder to miss rocks etc.
(Unsprung weight translates directly into hotter shock oil, and wider track makes it understeer and steering a little harder)
Rolling resistance aerodynamics, and masking of air flow to brake pads are worse as
well but these don't relate to
suspension so much like the others.
Not sure what you run leroy , but throwing a set of 235/85/16 on a Patrol is like a breath of fresh air as steering and feel of car is lighter and more responsive.

Strewth, if these issues occur with 285/75s, then I'm in for a rough trot with my new 315/75s (but I already knew they would cause more wear and tear on my drive-line). Bearings will be another casualty I suspect. However, I am running 8" ROH Sunraysias Trak IIs and these have an extra 20mm offset......so the brake pads still get plenty of fresh air (you can easily see the little inboard scoops when viewing the truck from the front).

Hi Roachie
Your front end would probably float if you fitted the standard 7.50X16 of the DX Patrol

285 MTR's were good on my standard alloys, but you do need the spacer on the rear door..

I would not worry too much about the spare carrier, I run 35inch x 12.5 inch x 15" Mickey Thompson Baja Claw Radials, and the spare fits fine, have no
suspension problems and have dropped my highway RPM by having the larger diameter tyres.
Hope this helps.

I can supply a 6mm wheel spacer at $15 + postage that will do the trick.

I run 285/75/16 Cooper S/T's and the spare fits on the rear door ok.
It clears the doorwell by at least a finger thickness at the bottom and more at the top of the tyre. I don't think the slight extra weight is an issue. After almost 2 years of driving this way I have seen no ill effects.
