Same size as before, 315/75R16. Thanks for the heads up, I've heard about that, and saw a modified Hilux pulled over in Bilpin on the weekend. I haven't been driving the ute far from home at the moment.
I also picked up a set of HZJ105 GX 16x6.5 steel wheels to match my spare. I'd like to try a set of 255/85R16 on these.
