I have a 2007 Tundra with a 2.5 OME lift front and back for use as a Fire QRV. Currently have the stock tires and wheels on it. Looking for a bigger tire that will fit with the lift with no mods. ALSO... VERY IMPORTANT... needs to have clearance for chains during snow/ice. Have looked at dozens of threads about 285/75r18 and the 305/6r18 with no mention of chaining. Can anyone help?!
