Thread: What happened to your D3/D4 today?

Its the tyres, you’ll use an extra 0.7-1.0l/100km on these compared to HT’s. I run mine at around 43-45psi cold, gives pretty good economy, but the rides a bit harsher due to the LT construction. I’m on 9.3-9.5l/100km on my 980’s, about 30,000km in.

I only had my car for 1 day and changed the tyres. But what I did notice was that the new tyres even though same size as OEM, are a lot heavier. Then when I went to Compomotives and 18" tryes they are a lot heavier again than the Maxxis on the OEM rims. Results are that with maxxix tyres I get better (true measured) L/100kms, than the 18". Extra weight, more rolling resistance= more energy to rotate tyres = more fuel used. Its not great difference but about 1/2 ltr per 100kms

43-45..wow that's up there😉

I run that pressure on a tipper trailer carrying 3 tons firewood...never on a car. Would that not run out the tyre centres fast and make them behave like a skateboard esp in the wet? I run 32-35 for daily use. Dealer had 28 in them no doubt to accentuate the ride!

I go 38psi on the Bridgestone 670s

The Gen.2 Zip Kit I returned is probably the right one for your D4 which is a ZF6HP28

Don’t discount a pit. I’ve got access to a pit at a friends house. They are soooo good.

Almost impossible to construct now with the compliance requirements.

And can’t do body off jobs with a pit
Or park another vehicle underneath

Of course I’d love to have a hoist but that is next level dream world stuff needing space and height lacking in inner suburban settings. Fortunately the local men’s shed has one

The pit is quick and simple for most service jobs and makes life easy.
