Which rear tire drives the Comanche?


Recommended Posts

Hello.  I have a quick question.  I have an awesome 1988 Jeep Comanche Pioneer, 4.0 4x4.  I recently 4 purchased used tires with Jeep rims.  The four tires vary with usable rubber remaining.  I am thinking the 2 best rubbers will go on the back and the 2 less rubbers will go on the front.  The question is do you know which rear tire I should put the best rubber on rear driver or passenger?  Would you recommend any method of putting them given the rubber remaining?  Thanks very much.  I am always a fan of your forums.

Hmm, unless you have a preference in which way you steer, like nascar, it doesn't really matter wether its on drivers side or passenger traction wise. If you've got a stock truck, you'll have an open differential in the rear, meaning the power goes to the wheel with less resistance. Turning left or right constantly changes this. I'd just put it on Left Rear, it might not be much, but the better tread will provide a smoother ride closest to the driver. 

 

Edit: forgot some stock trucks had LSD diffs, but the point is the same.

The one that gwts the most traction?

 

Correct.

 

And my preference would be to put the best tires on the front. The front does all the steering and the major part of the braking -- I like to have some ccontrol over my vehicle when driving.

I'm gonna have to disagree with you on that one. The way I was taught, the best tires are always put on the rear, for this reason: http://www.discounttire.com/dtcs/infoTiresRear.do

 

This is regardless of front or rear wheel drive.

Brought to you by the people that say front wheel drive is superior.
As I plowed into countless snow banks with FWD that I could of easily avoided with a rear wheel drive vehicle.
I'm with Eagle, better tread in front. I've never had a problem with the rear coming around on me like the article describes.

Yeah, I know there are people out there who want to put the best tires on the rear, even with rear wheel drive. I've never agreed with that, it defies logic, and real world experience proves the opposite. You're welcome to disagree, but that article isn't going to change my opinion that's based on driving for 54 years and well over a million miles. (Closing in on my second million, but I don't think I'll ever quite get there.)

 

The article assumes you can steer with the front wheels. In the real world, if you don't have decent tread in front you CAN'T steer -- especially in wet weather or snow. If your front, treadless tires hydroplane, you're going off the road. The difference is you go off nose first and smash head-on into whatever's out there, rather than maybe fishtailing and sliding off the road sideways.

In two wheel drive with an open differential either rear tire could get full power depending on the friction of the driving surface. However due to geometry and what I assume is unexplained magic the right ( passenger side) tire will be the one most often powered/spinning if both rear wheels are on surfaces that will cause to tires to slip when overpowered. If for some odd reason you had only 1 tire with better tread that is where I would put it.

That looks more like a reason to keep the bald rears. Rain is just an excuse to power-slide everywhere when you're on all terrains.

I also neglected to say these people won't even touch your car if you only want two tires, and the two that are staying are below a certain tread depth. They would all have decent tread. I hate to disagree with people that have that much experience under their belt, I've always been fortunate enough to have four new tires when I've needed them, so I have no experience with bald vs new tires. I will always go with the voice of experience and reason over popular belief. Thanks for the input.

the reason for the right rear tire usually spinning first is due to the rotational torque of the driveshaft trying to lift that wheel, causing it to have slightly less contact area and weight.

Bingo!!

Costco has the same policy as Discount Tire. If you buy two new tires, they will only put them on the rear. I was looking for two for my bride's Mazda 6 - a front wheel drive vehicle. I didn't buy them from Costco.

Regardless of where these automotive geniuses obtained their enlightenment, I'll always put the best tires up front exactly for the reasons Eagle stated. The fronts do all the steering and the majority of the braking. If you have a problem with the rear coming around on you, either get better tires or lighten up on go pedal.
