I have a 2012 Sequoia Platinum bone stock. It currently has the standard 275/55r20 tires on the stock 20x8 rims. I would like to upgrade to a larger tire 305/55r20 which requires a wider rim 20x9. My question is basically how much positive or negative offset I would need to clear the fender as well as not rub the wheel well. I don't plan on lifting the vehicle as the only option would be a 2" spacer body lift due to the air suspension limitations. Anyone out there with a 2008+ sequoia running 305/55r20s on stock suspension? Any regrets? Fitment issues? Thanks!
