Thread: D4 on 35"?

Sorry guys been away,

Wheel size is 20" and the tyres are Nitto Terrain Grapplers AT's 275/55R20 tyre sizer suggest 31.9" - meassured size off vehicle 32.3"

The reason that I use a tyre size chart and a measured size is simple, 275/55/20 is a carcass size. A Mud tyre will always be taller than an All Terrain Tyre (13.5mm) and both taller than a Highway tyre due to the amount of tread depth.

The tyre size comparrison shows the tyre is 6.3% taller than what was on the vehicle with 19s.

And - are these your daily driver tyres? If so, how do you find them? I'm tempted to go to 275/65r18 for my next set of daily drive + trip tyres (currently at 265/65r18 and loving it).

Metric is a smidge over 820mm when off the car, I run them at 38psi and that gives me a fantastic foot print for dirt, mud, gravel, rock and (river) sand. (I live in FNQ).

The speedo is spot on to my GPS which is great. The fuel consumption on the computer has gone up from 8.3 ltrs per 100 to 9.5 ltrs per 100 on a run. but on GPS miles its the same on a run.
Around town it gets up to 10.2 ltrs per 100 a little more than before, thats stop start turning a bigger wheel.

Yes I use these tyres daily. No issues in driving, ride or anything done just under 30,000kms so far. Where it really shines is off road, the GOE gives you an extra 2" in body/ride height, but the tyre grip is fantastic, the extra side wall is a bonus.

What offset are your wheels?

I think that they are 45, might be 40 but 45 rings a bell, Will look for the specs.


Found it.. 45 offset. When i checked the full spec these had a higher load rating than the standard 19" wheel.
They give me a wider range of tyres to use as well.

I have given up on ever getting my 18" rims from GOE so I will be pricing the 275/55/20 Nittos this weekend.

34" is possible....
If your keen.

Just a word of warning...

It is possible to run these larger sizes using LLAMS, IID tool, Rods or some other means to lift the body away from the tyres. However if you have some sort of problem which causes the suspension to drop to the bump stops the tyres will be touching either the chassis (D4 front especially) or the inner guards (body seams on a car with rear air) and you may not be able to proceed without fixing the problem or using something to isolate individual air struts and pump them up.

If you are moving along at 100km/h and your suspension lowers you don't have a lot of time to pull over before things rub. Driving on the bump stops is pretty uncomfortable but it least with smaller tyres you are driving.

This is not to say you shouldn't do it. Just be aware of the risk, having had both my previous D3 (a dodgy height sensor) and my current D4 (my fault) lower at inconvenient times in the past I decided it wasn't a risk I wanted to take.

Agree.... I say it again and add a little fruit.

Lifting via Rods or IId

Etc etc etc ... Hahaha.
