Just installed some 37" BFG All-Terrains... for giggles I put a measuring tape on them... the height actually measures 35" -- barely. How the heck do tire manufacturers calculate their measurements... I neved did check the actual tire size of my old 35"s. Just curious...

Are you measuring the ones supporting the vehicle? If so, the bottom of the tire is deformed.

They'll rub just a little as you can see in hawk's pic. Nothing to worry about.

My 35's rubbed in that spot before I got the weld rims.

It depends on your alignment. When I first got my 37s on, no rub at all. A dealer alignment screwed it up tho.

Your sway bar can slightly move from side to side as well;)

Several factors will effect actual height, mainly; the weight of the vehicle, the tire pressure and rim width. Manufacturers will measure the tire without any load on it, sometimes at max psi and the height will be for a specific rim width. Add a load, lower the psi, and/or use a different rim width and your measured height will be different.

My 38's only measure 36.75" when on the vehicle.

Phil -- THAT was the help I was looking for. I figured that pressure, load weight, rim size, etc. would account for various standing sizes. Appreciate your help. The rack and ladder look fantastic -- thanks! Rancho lift went on great... I'll submit pics ASAP.
