Tire Size and AWD [Merged 5-7] diameter radius rolling different sizes size

All 2G AWDs have a VC LSD in the center. Some have a VC LSD in the rear, too, and some don't. (Someone correct me, but I think that the non-LSD rears don't have heat fins on them; I know the LSD version does have fins.) The front on all 2Gs is open.
Heat fins are metal fins on the diff to dissapate heat. I don't know any other way to say it. Take a look at a subwoofer amp. Those are heat fins all over it.
I also think that you can see whether or not you have a rear LSD by reading the info on the door jamb, but I'm not sure about that.
In any event, why not just test the car? Jack the entire car up and spin one rear wheel. If the other one turns in the same direction, you have a LSD; if it turns in the opposite direction, you don't.
Popped a tire from a nail. All tires are about halfway thru their tread. Will putting one new tire on the front left be bad for the AWD or differentials? Got a quote for like $485 for all 4 and im poor. I can buy them if i need to but i will be almost broke.
I've heard that you generally want to get atleast a pair changed on an AWD car if one of the tires goes, that way you keep everything similar throughout either the front or back. It might be an urban legend but...it actually makes some sense.
Check out www.tirerack.com. They have good prices on tires and are quite reliable.

This is half true.
No matter what you want to keep the exact same size tire on all 4 wheels.
Having some with 50% tred left and 1 with 100% tred, I really dont think will matter at all.
If you can get 2 new tires, it would probably be better, but not neccesary.
Reason you must have all of the same tires/wheels, is because if not, it would strain the VC in the trans, and eventually wear down. This = Not good.
As long as you get exactly the same tire as the others the difference between a new tire and one worn 50% isn't going to cause a problem. The difference in diameter is less that the difference between a underinflated tire and a correctly inflated one.
If you can't get the same tire then you should replace them.
What your stressing when the diameters are off is the VCU not the transfer case, either the rear or the center depending on where the different sized tires are.
It depends on the damage. Used to be you weren't supposed to patch a radial more than about 1½" from the centerline, depending on the tire and model. The amount and type of damage to the tire is also crucial- a simple nail or screw hole will patch up with a plug in most cases, and plugs work fine and can be done in the driveway without a jack. See what the shop tells you.
One new one is kinda dumb, but it won't affect the drivetrain enough to kill it.
this girl i know bent one of her rims and i was going to give her one of my old ones (same style) but the tires are different, would it be ok for her to use a different tire but with similar tread on the one tire then the rest? shes an autoAWD
I've an AWD and one of my tires is near bald due to a poor balance after being plugged. Bad new is that Dunlop no longer sells the W-10 so need to get a different Model.
Question is.. can I just replace two (both rears) if the size/profile is the same as the fronts? I have 2/3 tread on the three good tires so would hate to junk them.
I know that performance-wise the tires may be slightly different.. more concerned with messing up drivetrain parts.
I've seen it done with no ill effects but i work for NTB in DE and we are told by the company not to do that on anything awd. Im guessing they have paid for a few transfer cases and decided its not worth the liability plus 2/32nd would fail a PA inspection there almost at the end of there life anyway. oops i thought you said 2/32nds not 2/3rds oh well as long as you keep a very similar tread you shouldnt have a problem
Try to get tires with the same size aspect ratio (overall height) as your front tires. As long as that's ok, then your center diff will be happy.
In terms of mixing and matching tires, as long as you try to match the tires' "stickiness" with the ones you'll have on the front, then you'll be almost ok.
Read the sidewall of your front tires, and try to match:
Tread wear
Speed rating
(and maybe price)
If you put cheap/non sticky tires in the rear, and you've got sticky tires in the front, then you'll have oversteer.
If you put MORE expensive and very sticky tires (maybe wider) in the rear, then you will have (cornering limit) understeer. Although the understeer tendancy will be the same as before you had the old tires on. This set-up will make the car more stable.
With varying tire compounds, you will vary the tires' slip angles degrees (or the point of which the tire slips extremely, and the car slides drastically). By matching them as closely as possible, the car will be more neutral while turning, and you should be fine.

Actually.. was your shop that did the plug (Kirkwood Hwy?).. get me a deal on some 215/45/17s and all's forgiven
BTW.. I found a couple online shops / eBay that can do 4 name brand shoes for < $400.. so may go that route. Just pisses me off that I've got to waste the remaining 3.

Was looking to replace with the Dunlop SP9000 which are the same tire (all-season WR-speed rated) but diff tread design.
Im actually at the one up on concord pike by the concord mall. I can get you a deal on the tires the company will beat any advertised price so find the best internet price you can and print it out ill hook you up.

And you'd be guessing incorrectly, which is why you're not supposed to guess. The VC for the center diff (which is what suffers when the front and rear diameters or grip levels are unequal) is in the transmission, not the transfer case.

Is it bad to get ONE new tire with AWD??
She's already wrecked two hehe
