Problems running 1 new tire in 4WD??

Sounds like my solution until I need a new set. Unless I can find a shop to shave the tire for me for cheap, then I just wont have to worry about anything at all.

Thanks for the input, fellas. Learned some new stuff here today!

 

Get the tire with more tread, and a junk tire and go do lots and lots of burn outs?

 

That sounds MUCH MORE FUN!!!! haha I actually have an extra tire with a deep sidewall gash.... hmmmmm

I wonder how long of a brakestand I have to do to burn off half a tires life.

 

Wrong. The ADD is in between the passenger axle and differential. In 2wd it is disconnected. Therefore, the differential is only connected to the drivers side, and the passenger front axle spins freely with the wheel.

Both axles spin regardless of 2wd/4wd, but the two sides are not married until the ADD connects (4wd).

 

So does it matter which side I put the new tire on (drivers vs passengers)?

 

Nope.

 

Sweet. Thanks for the heads up!

I don't know much about 4WD driveline mechanics, but I think I learned some stuff today

 

pretty quick fire with the DERP//hahha

anyways. sorry if i am skeptical when a tire manufacturer tells us we should really buy tires four at a time. AWD..i get it. follow specs.

but does Goodyear apply this spec 7/16th..to ALL cars?

i think the slight difference in tire size on the front of our trucks..is no big deal. in 2wd..the system is open. GP3 understands it the way the toyota guy explained to me.

what about the guys that have a flat tire out in the middle of nowhere and needs to rely on the new spare tire? one bigger? nowhere does the owners manual tell you that you are screwed...just put it up front. what about the folks that stepped up to a larger tire and still have the stock spare?

just asking..because i want to go to 267/75..

 

If you step up to a bigger size, buy a spare of the same size. That's all part of being a responsible truck owner. If you must use the donut spare, it's to be used as a means to get to a tire shop, and that's it. I think in the short term, the drivetrain will be fine...especially if it's just one spare on the front. If you must use 4WD, make sure it's NOT on high traction surfaces, to avoid binding. If it's on the rear, it'll be fine for a short time, as stated. The diff will be working harder and will wear out faster, but you should replace the tire way before that happens. I'm definitely at fault here for not have matching tread tires, but I was merely asking if my truck will be ok for the time being.

I'm looking into tire shaving...some interesting stuff about it.

 

I understand, I don't know anything about the 7/16th. I'm just saying when I used to work in the tire business you should always have like tires on the same drive axle and like tires on all four wheels for an AWD.

I assume the small spare is fine for limited miles, someone will have to check their owners manual.

 

If they was enough difference your ABS would be having a fit drive more worry less. Tire ware is so fractional nothing including you will notice the difference just don't mix sizes.

 

Don't listen to the fools. It makes no difference on a 4x4.

Now on an AWD yes it matters.

 

I wouldn't say it makes no difference. In the front, since the cvs aren't connected it makes no difference, until you run in 4wd, and then it shouldn't make a difference because of the length of time and surface you're running on. On the rear, any appreciable difference in diamater causes the spiders to walk all the time, rather than only when taking a corner. I'd be okay with a slight difference but a blanket statement like you made doesn't sit will with me.

Also, OP, 7/16 is 14/32 and that's about the depth of a new tire. Are you sure? That means your tires are at like 2/32 tread or bald.

 

Some places will shave a tire to match the rest.

 

Hey Matt Just my .02

I had a flat on a front tire and they were 285's and I ran my stock spare 245 on there for a couple of days and NO abs lights or anything came on... Also I ran 2 stock 245 spare on the front this last time I damaged the front rims and nothing flagged with ABS but they were both on the front...

 

Possibly he meant 7/32? I didn't measure them myself, but they definitely have more than half the meat on them.

Good to know, Chris...no dash lights for me so far, and I wheeled her pretty damn hard last night.

 

Must be, I wouldn't worry about it then.
