Ouch! I just ordered my full size spare; a 20" Fuel Vector (D57920909452), a Toyo AT2 Open Country 305/55R20 and a TPMS sensor; CAD$1073.55 (including taxes) so if going this route or similar, budget for CAD$5300+/- for five new wheels. I also ordered my Wilco Hitchgate Classic, offset, complete with license plate relocation kit, another CAD$1422.37 (including taxes). I do plan to go off road so the full-size spare and somewhere to put it are not an option. I'll post pics!
