BJs Wild RideHoosier 17-34.5-16
I got a set from Jegs. Advertised rollout is 110. They are marked as 114.5.
I’m replacing a set of 34.5-17-16s. These new tires look huge next to the old ones. I’m a little worried they won’t fit under the car after I get the mounted. I’m tempted to call jegs and ask for them to swap but not sure if the 114.5 is typical?

bry-warAfter a tire is cured, it is removed from the press and placed on a machine called a "post-inflator". On this machine each tire has air injected into it for a set period of time. The amount of air is determined by the engineering department and is not the same for every type of tire Hoosier produces. After a set time period, a tire is then measured and the circumference is recorded. Then a press operator writes the size on the side of treaded tires and on the tread of slicks, in chalk. All Hoosier bias ply tires with a chalk-mark, follow this same process.
