Running two different tire sizes

Uh, yeah..........that's why I stated the road wheels.........but it's the same theory going on in regards to the road speed being related to the rolling radius and not the entire tread surface.
It's not either of those, it's the radius. Measured from the center of the hub to the ground. I'm thinking a 42" tire aired down enough can equal the same radius as a 40" tire with more air pressure. That measurement should be the one that matters. With that measurement equal the vehicle should act as though it has the same size tires. Theoretically. Right?
I concur! I would measure them to make sure they are the same radius front to rear. Would not do it long. Sand should be alright as everyone else agrees. THere is one thing to think about though. When a tire is air down the edges of the the flat section of the tire has a larger radius than the center flat portion of the tire. I would think you may want to average the two measurements. Just an idea.
When my blazer had miss matched gears thanks to the previous owner (where is that missile?
)3.73 in the front, 3.08 in the back. My blazer did alright in the soft sand, but when the sand got firm, the blazer would start to bind up.
With a motor with a bad lifter and miss match ratios the wrong way, it made the blazer a pig. I would had preferred the higher ratio in the front. It is better for the front to "pull" than the rear to "push".
