Eddie @ Sellicks Beach

G'Day Lads, Need a new set of tyres for twin cab 07 diesel manual. So far have used 265 bridgestone duelers on 15 inch SR5 rims without much success (breaks traction in wet) and also coopers 225's on the 16 inch SR rims (they fell apart way too early). Thinking about sticking with the 16 inch and a 215 or 225 8 ply tyre. Mainly used on road but some gravel tracks/beach on the odd occasion. Would like some suggestions on brand and sizes if anyone feels they have good advise? Thanks
