I have a 2000 ranger, but how do I find out specific info about it such as gear ratio, stock tire size, and just general info specific to my model year?

what model, motor,off road package,disk brakes in rear???mine is a 2000 xlt supercab off road drum's in rear. 4.10 gear's, 245/75/16 stock tire size. tire size should be on drivers door side by latch.

Not sure about newer trucks, but my 92 has a tag bolted to the rear diff. cover, stating type of axle and gear ratio.
