on one of tires, the sidewall is ripped a lil. im about to change it but does that mean i have to change all four tires ??? or can i change the ripped one. my friend tells me i have to change all four any ideas?

 

how many miles do you have on the set of tires?

 

yeah you have to replace at least 2.

 

if theres a 3/16 difference (or something like that) you have to change all them.

 

no... you change two at a time.

 

He is right. With all wheel drive, there are only certain percentage of tolerance on overall diameter (comparison from front to rear sets). Otherwise, your differentials may go bad. This is why it is a bad idea to go staggered setup on all wheel drive...

 

How did the sidewall rip?





Also, your name takes me back to my first date with my wife =)

 

i live in ny and the roads here arnt as great as other places. hmm gettin mixed answers here 2 or 4

 

please let me know how a viscious center diff works? they respond to TORQUE, so if you're rolling both wheels at essentially the same rate give or take a little bit the vcd is not locking.

how does a hydropnumantic clutch type center differential work? it response to WHEEL SPEED, TRACTION and various other data INCLUDING torque. there have been NO reports of acd units throwing 50 50 lock on the car while running different tires and i have friends that shave in 2 of their ra1s at the track at a time, basically going from near corded in the front to brand new in the back... that's MORE than 3/16s.

 

ok i have no idea wat u said so how many do i need to change?

 

two at a time and simply for the sake of it being easier, so you don't go gimping around for the rest of your car's life.

the main point is to keep the traction similar on each pair of wheels.

 

+1

 

thanx

 

u guys think i can get 2 diff ones for the front then the ones i already have?

 

maintain similar traction all around, otherwise things get dangerous.
