I have a flat tire on the passenger side of my car. I went to get a new tire and I was told that no decent mechanic would sell me one tire for my jeep grand cherokee 'cause it would mess up my transfer case. I was told I had to buy four brand new tires if I didn't want any damage to my car. I went to two different places and got the same answer; Something about the difference in tread wear. I didn't buy anything 'cause I wasn't sure. It's my first car and I am just learning about car care. Anyone know if this is true?

I checked the owners manuals and it doesn't mention this. My local jeep dealer is an hour away and I can't call 'cause thier closed. I brought four new tires for the car when I first got it and it's only been like three months since. I don't think I've driven more than 800 miles on those tires

this is very true to an extent, not something most people know, and i commend whoever told you this. here is the reason. the part time/full time and full time 4x4 cases both are tire diameter sensitve, but a little different. the part/full has 2 planetary gearsets. if you put it in 4x4 with different size or differently worn tires, the case will not disengage when you take it back out. the light will go out, but it will stay locked until it feels like it wants to come out. it may never come out. driving in 4 wheel drive on dry pavement stretches the chain in the transfer case to the point of destruction. the full time case has a viscous coupling to cut down on bindup when turning, but if you have different size tires it will fail. is saw one jeep with different size tires completely destroy the front differential 3 times before anyone noticed the tires. i just had a liberty not long ago with the part/full time case with abnormally worn tires. he had put it in 4x4 and it didn't come back out so he just kept driving. by the time i got into the transfer case, the chain had stretched so far it cut through the oil pump pickup tube and starved the internals of oil. so if you can't afford 4 tires, buying one used one is a great idea.
Now that you say you only have 800 miles on the tires, go ahead and buy one new one. 800 miles is nothing.

Sounds like a b***s*** to me but I'm not familiar with Jeeps, I've had numerous 4x4 trucks and I've always replaced a bad tire with one of the same size. My wife ruined a tire on her '97 Dakota pickup and we put a new one on, B.F. Goodrich All Terrain Radial. The tires were about half tread at the time and the new one never caused any problems other than we buy three new ones at one time and the fourth about two years later. Just to be sure check your owners manual, that's what it's for, or stop by your local Jeep dealer.

Yes this is true .. but the 3 old tires have to be pretty much worn out. If they are , and u can't afford 4 new tires ... get a used tire :)
U can probably get a used tire and even a wheel for Allot less than 4 new tires cost

Yeah, unfortunately its true, but only if your tires are really worn. I suggest buying a used tire that matches your current tires. That's what I would do if I wasn't ready to buy 4 new tires. Good Luck

yes they are right it can very easily screw up your transfer case, if you have only put around 800 miles on a NEW set of 4 tires i wouldnt worry about just replacing one.
they only say that about 4 tires that have a alot of wear on them.
it goes for all 4 wheel drives not just jeeps

Depends on the type of 4WD your car is equipped with. Damage can occur with full-time units. Part-time will handle the tire differences since the car is usually in 2WD 99% of the time.

it doesnt matter how much tread your tires have, or any of that other junk these other guys are talking about, just make sure its the same size, and if you cannot find the exact kind of tire, try to match the tread as close to another tire as ya can, (winter tires, summer, all terrain.. etc.. )

Its crap with that little mileage, although when you get more miles its a good idea to change at least 2 at a time, someones trying to get more $ from you cuz you're a woman, and they figure they can. Go down there and tell him to do it anyway.

Who ever told you that is a crook. As long as it is the same size as the other tires it DOES NOT MATTER.
