Yes, they are 2" taller-both tires measured off the vehicle with a digital level and tape measure. I don't believe the stockers are a true 27". They are very soft rubber compound, that is why they are lighter. A stiffer compound- 8 ply- will hold rigidity better. I think this calculates to the big differences in height comparisons, to the stockers. Maybe my theory is wrong? Other people have a better conclusion?
