The way to go for the rear is do the 9.5 inch rim widening. Can use the Toyo 295/45/18 Proxes STII all season. They do stick very nice especially in the wet. Had the Hankook Ventus AS, terrible, slid all over the place. Before that Nitto Gen 1 555 summer. Lousy in wet as well and I think the Toyos are better all around. For summer I might do 315/40/18 Gen 2 Nittos, they stick. Will need to go even wider on rims and spacers will be needed. Fronts I'd do the Michelin AS3+ in 255/45/18. Currently using BFG Comp 2 AS also good. Both fit fine on 8" rims but 9" would be optimal. Tire height is 27.1 inches, stockers 27.3 so perfect. I'm looking for widened rims (9") if anybody has them. Thanks, Stan
