15" wheels maximum on dirt, 16" is too big. Not sure if the Bates team use 19's either, I think they stick with 18's on the rolla. They used 19's on the Aurion they had though.
Also, its no longer the TRD racing team, its Neal Bates Automotive only. And Rally Tasmania was Tarmac last year too.
And someone put one of those bonnet scoops on a ZZE Rolla, but had nothing under the bonnet to match it.
The wheel is likely to be 18 inch
as according to their website the WRC model only goes up to 18
