4wd truck math problem

[bodypilot90 0]

we were talking in the shop about one of the guys wanted to put large off road tire on his truck. It was suggested he upgrade his brakes because of the added tires and rims.

Is there a math formula to figure the amount of energy stored in tires due to the "fly wheel effect" of each tire? Thanks

The brakes sure, you could upgrade them, typically unless he's going to something like 40" tires it isn't too big of a deal. The thing he's going to find is that the balljoints will wear out quicker AND he's gonna have to regear his rear end.

So Aggie, based on what you're saying, is there anything I can do to my truck to make a big difference in gas mileage?

I drive an '01 Chevy 2500HD 4WD with a crew cab. I just went up 3 tire sizes, nothing major, but some beef and fills the wheel wells.

All of that is important, BUT if you don't regear your rear-end, you're not doing the most important thing! Even a minor regearing will fix a lot of your milage. Then changing your computer over for the larger tire size.

The simple things like intake, exhaust and possibly a throttle body spacer are givens, you should do those before the tires even go on. A stock truck needs that stuff done for better power and better milage (if you keep your foot out of it).

and, find a good dino shop somewhere, they can tell you the optimum gearing and such.

That's good, but with most stock rigs that are slightly adjusted (X lift with Y tires, change to Z rear-end) simply done by the math and common sense with the shops. Of course that assuming a quality shop, not your coner store oil-change monkey.
