Re: Rear tire skidding when downshifting
You are not rev matching when down shifting. The engine has to "jump" to compensate for this delta when you downshift. The force is immediately being transferred to your back wheel locking it until the rest of your drive train catches up.
If you are 10k RPM in 3rd and downshift with no rev matching and no "ease in" to the clutch (basically letting the clutch burn and take the hit until the RPMS line up) your rear wheel will lock once you release the clutch. The engine is still going 10k RPM but now your gear box is in second, where the gear ratio in the transmission dictates that the revs should be higher for that gear at that speed.
Long story short - learn to downshift and rev-match (at any gear at any speed within the engines tolerances). You will either blow your engine or go down after locking your wheel bad enough..
