Hi all
I just got a bit rent in the side of one of my tyres. Changed my tyre with my brand new spare. I was considering the difference in tyre diameter on the lsd given one tyre was brand new and the other near worn out. That is to say my back tyres now have different wear. I was too lazy to rotate my tyres in the field and drove home. I doubt there could be a problem over a couple hundred k's? Does anyone agree/disagree??
Cheers Hardy

Depends on the type of LSD I guess.

Couple hundred ks shouldnt kill it, just generate a bit of heat and wear a bit off of the cones/clutches?

I am wondering would it be any different to driving throught the twisy mountain roads where the continuous cornering would mean that the inside wheel is always turning at a different rate than the outside ? Although I agree that sustained driving for a few hundred kays in a straight line might be a different story.Cheers,

Driving for any great distance, I'd be concerned and would put the odd one to the front. LSD do not like to rotate for any great length of time, in fact the less you can stress it the better. I remember 9" Fords getting the LSD plates chopped out of them after one hard weekend of wheel spin in muddy conditions, but there again, they were esentially a sedan diff, not 4x4.

Hardy It would cause absolutely no problems. I think you may be confusing LSD with a diff lock. A LSD gives just what it says - limited slip - and after all can you think of any road which doesn't produce different speeds in opposite wheels? Every bend, curve and corner causes different wheel speeds and that what you have a diff for.
