I tried to search for this subject with not much success.
Has any GU Nissan owners out there gone up a tyre size and if so what size and what make.
I am very unhappy with a set of Bridgstone that came with my car, 24000km and the rears need changing, Bridgstone are going to look at them tomorrow with a view to replacing them so I thought I would change the size. Might help to bring the speedo in line with the GPS.

Algee,
Definately go for a bigger tyre size. I have had both 265 and 285's on my two 3 Litre DI Patrols and the motor pushes them both along very
well, whilst noticing a slight power drop from the 265's to the 285's.
The 265's are generally cheaper than the standard size tyres on the Patrol, are available from more remote locations, give you another centimetre or so ground clearance to the bottom of the diff, and you will notice hardly any difference in drivability. With all of these reasons behind you, I would definately 100% say change up.
With the 285's, you get another centimetre or so clearance to the diff, but more expensive tyres, a slight reduction in power ( drove my brother-in-laws identical car, his with 285's and
mine with 265's, side by side, and even with the power loss, decided it was worth changing up to 285's for my type of driving since I keep damaging my side steps walking the vehicle through deep holes. )
Next step is to decide on what brand/type --- that's even more fun than trying to get the right size!!!

I have 305/70/16s on my GU TD42T, previously I had 285/75/16s as my touring tyres. (both sizes are 33")
Well worth it for the extra clearance under diffs but with a slight loss of torque and increased fuel consumption. Engine braking and braking are also affected. The 315/75/16s really require increased braking ability (front slotted rotors) and new diff ratios (4.6s) as
well as knocking a lot off of performance.

Algee,
I'm happy with 265/75's. Got the Nissan sticker to cover change of tyre size.
I believe that if you fit the 285's, you will have to modify your wheel carrier on the back door to accomodate the bigger tyre.
As an aside, everyone reckons that the bigger tyres make the GU speedo read slow or occasionally spot-on.
Mine is still 3km/h fast at 100km/h with the 265/75's, so if I had run with the original 265/70-series tyres, the speedo would have been hopelessly inaccurate (and the warranty would have run out sooner). Odo is now spot-on with the bigger tyres.
Had a hired current series 3.0TD for a week late last year, and found that the speedo in that was 4km/h slow at 100km/h (std tyres), as I found to my dismay as I went thru a radar trap.
Cheers, Gerry
