do you know how they wear on the road obviously designed for off road but i do bit of both..im running 15x10 rims on hilux and 32x11.5x15 goodyear wranglers but slightly rub and lost lot of power also have turbo on 2.8 which helped

have you considered changing your diff ratios to help bring your gearing back? rather then replace tyres?

yeah did think of that but what ratio..i jacked back end up and done 1 rotation of wheel which was 4.5 turns on drive shaft so ratio now i think is 4:5:1 does that sound right..id plate on firewall does not have axle number for some reason just has g52

G52 is your gearbox. and if your rotations of d/shaft are correct then you have 4.5 ratio diffs too. To improve diff ratios you need to go to 4.88 but have heard that they are a weaker diff as the teeth are thinner.
I have 4.88s in my Surf and running 33s. No worries...yet....
