Hi Jonesy
We replaced our original 18" Wranglers on our D4 with the EfficientGrip SUV last year. We got 48K out of the Wranglers, but they were well worn and noisy by then . At our 48K service the dealer said we had to replace our left front wheel bearing, but was just the tyre.
We considered getting the Pirelli Scorpion AT, but as our D4's main function is to tow a 2.3t caravan we were concerned about reports of aquaplaning. When Goodyear had a buy 4 pay 3 deal on the EfficientGrip SUV we decided to give them a go. Ended up paying around $1000 for the four tyres including a wheel alignment through our local Goodyear centre (Caboolture in Qld).
So far they have done 14K and feel very similar to the Wranglers on the highway. They are very quiet and so far have been very good in the wet - we have had a lot of rain in SEQ in the past year. We haven't taken them off road so can't comment on this. They have been good on dirt roads without the van. The tyres don't have an aggressive tread, more designed for highway use. So far no noticeable wear, but as mentioned only done 14K.
