Hi - I do some off-roading, fire roads, and general exploring. The Hankooks are not so good for anything other than road driving - I've already punctured one and would like to replace the OEM Sport tires with the next larger size tires - 275 R55 20. Has anyone done this? Curious to know if they will fit. I'm looking at both the BF Goodrich Rugged Terrain, the Bridgestone Revo 2, and the Firestone A/T. Any feedback on this would also be appreciated. Thanks!
