One bad tire, have to replace all

[ace10]

a week and no update... c'mon dtrout, what's the word?

Still debating the whole thing. The tires came in the end of last week, but it is Costco, and not paid for so no hurry. Really not sure that I want to spend the money on new tires that I don't really want. The Revos are awesome tires on the road and in snow conditions, and the type of offroad I have done so far I am satisfied with them. Don't know that the BFG KO's will be as good on road and in the snow (tirerack ratings at least). I drive a lot in winter mountain conditions headed skiing, and have yet to even spin a tire while driving with the Revos. Also trying to figure out how a couple mm's of tire could possibly affect a 4wd system, as my spare is a OEM unused spare Michelin. I would rather buy Revos in 285, than a tire I don't know anything about and smaller than what I had planned. So still thinking and researching things.

It is fulltime 4wd, but there is no viscous coupler, same as the 91-92 FJ80, it is just an open diff. The viscous coupler is what essentially makes it a limited slip diff, allowing the front/rear to "lock" (just during the slippage) if there is too much slippage.

Ok, I thought it had a VC all this time, If no VC then it won't matter with one new tire. On my VR4, it's all or none, Just like the Subaru’s- Because of the VC.

Buy new BFG's then on ebay or tirerack or someplace and sell your old ones on ebay people buy used tires on there all the time and for a good price. If you have a Discount tire in your area see what they will give you for the used ones.

Isn't it the front/rear diff that would matter, not the center? A tire of a slightly different size (say in the rear) would result in one side turning slightly faster than the other. An open diff would easily handle that, but on a LS diff, I'd think you could wear out the friction plates prematurely. The diffs are open on '00+ LC/LX's w/ ATRAC, right? IIRC, LexusBen responded in a thread a few months back on diff configurations.

if I'm not mistaken, an open diff will indeed allow for differences between the 2 sides, but would also have the driveshaft go at the "average" speed of the 2 wheels, wouldn't it? So, if you have one tire much bigger than the other, and you lock the CD, wouldn't that create binding if you're on a high traction surface?

Having said that, the difference in diameter is very small and if you lock only low traction surfaces you should probably be fine I would think?

I believe all diffs (front/rear/center) are open on all (US model) 100 series LCs, like dtrouts rig. The LX had a limited slip rear diff, at least in 98-99, not sure about the newer ones.

If I were you I'd go to discount let them prorate one tire, and replace your blow out revo. Put the two new tires up front, because if you corner like me they'll match the used rears in no time. That way you get to keep your Revos. I'd keep the tire you like. Don't let some one talk you into another tire if you don't want it.

It is always best to put the new tires on back, even (or especially) with front wheel drive. With older tires on the back, the vehicle will respond unpredictably and lose traction without warning.

dtrout,

I say sell the old tires on ebay and upgrade to 295/75-16's Terra Grapplers. I just did this to my stock '99 TLC and they look great and handle great. They are also pretty affordable.

Do you have any pics?

I'll take some today and post them for you.

Thanks!!!

I had this happen to me on my '04 L/C with the 2 year old Bridgestones that came from the factory. They had 47K on them and about 8/32's.
I bought a new Michelin and put it up as a spare running the 4 B-stones out in a 4 tire rotation.
My new set will be 4 new Michelin LTX M&S to match the new spare.

Not sure if someone already posted this info but a nail in the sidewall can be fixed. You will need to take the tires to an "independent shop" and they can fix it using cement glue. I paid $20 to get it fixed. It takes some time because they have to dismount the tire from the rim. Hope this helps. I have been running on such a tire for over 2 months now.

Here you go Subspd!






Sorry they are a day late but the rain prevented me from putting them up sooner.
