Thread: Changing to 18" rims

Are you running a 255/50 profile?

This is why I have had wheel carriers or door mounted spares on previous 4WDs - easier to access & no worries on tyre size.

I’ve just returned from Fraser where the D4 put lots of other vehicles to shame, particularly at Ngkala Rocks (much to the delight of my 13yo son). Generally ran with 19psi but 16psi for Ngkala.

Just note that with the additional sidewall, the spare must be deflated to fit under the car, so it means having a compressor handy if/when the spare is required.

The scorpions were my original choice, but not readily available so will give the geolander G015s a go - meant to be a similar on-road focused AT.

Had read up that the 65 profile was a little too large to fit inflated & may also cause some rubbing? Hoping 265/60s will be the right fit - 0.5 inch larger than original tyres.

Have you noticed any change in handling / acceleration going to a heavier rim and tyre setup? With the steelies and LT tyres I'll be adding a few extra kg per wheel.

>may also cause some rubbing?

No rubbing. I do have LLAMS and my normal ride height is a bit higher than standard height.

I recall being concerned about acceleration when I made the switch from the stock 19" rims and perhaps there is a very slight difference but honestly, the D4 has so much torque it’s not an issue. I certainly don’t think about it now. With the setup including LLAMS my car is higher off the ground so body roll only gets worse but it’s not too bad and worth the trade off imo.
