Purchased these 15" tyres from this website.https://www.ebay.com.au/sch/i.html?_from=R40&_trksid=p2050430.m570.l1311.R4.TR11.TRC1.A0.H0.X225+50+.TRS0&_nkw=225+50+15&_sacat=0
 
Ebay special til the end of month 10% off. Note the discount is from ebay... not the seller. Would have preferred Bridgestone, but have used and been happy with Falken in the past. They will only send to a depot in Laverton where you then need to arrange collection yourself.
