$1,000 for a 3 second line change test to put 235/85/16s on a D2 (Change lane at 100km/h in 70m).

So I don't think I'll go through the time/effort and hassle TBH! The guy on the phone was really helpful - he said the DOT had failed somebody for being 2mm over the diameter so for the sake of insurance I'm just not prepared to risk it.

Hey Jake

Pm me with the details of the engineer you spoke to please mate. That price is cheaper than the bloke I spoke to.

Cheers

I wonder if he would do an AULRO group discount?

I'd be interested..........

However, as others have stated, the 265 width is a great size on the D2 and I think what they should have had from the start. Most modern 4wd's now come with 265 tyres as standard. They track a lot better and there are a lot more tyres to choose from.

Yes. I had 265/70/16 in several brands and have now had 245/75/16 in several brands and mine tracks better, tows better and offroads better in the later size. Now if I had a lift I would probably go 265/75/16.

... I think a lot of that cost is to hire a track/driver for the swerve test so perhaps if they could all be done at once it might well make a difference.

I have 245/75/15 on mine, with no issues and without any lift. Good on road also, but it 'eats' a couple of HP from our Td5. A remap it is recommended for the best driveability.

/15 or /16?

Did your fuel economy go down too?

Happy Days

Sorry they are BFG A/T on 245/75/16 or 30,5" . The fuel economy remains the same, practically: 10 to 12L/100km in my case, re-mapped to a Stage2 from TD5inside.

just chucked a set of coopers at3 in 245/75/16 on the disco, got em for $300 a corner. Spare fits on the back, just.

Previous tyres were goodyear wrangler at-r in 235/70, they were actually pretty good tyres, didn't manage to puncture one in about 3 years.

Will give the coopers a good workout this weekend and report back.

Where in Perth did you get them that cheap?

See you on Sunday's trip.

Yeah looking forward to it!
My cousin's workshop is just over the road from a tyrepower so they have a pretty good relationship with them. He wasn't thrilled about the price it must be said
