Default Weird weird issue...

Okay so I do have two different sized tires on my ranger. I can go off road fine and engage 4x4, without issue, in fact I can engage it fine on the road to, and this is 4x4 hi. I put it in 4x4, and if I am going down the road it feels like my damn front end is being drug out from under my truck, and if I let off the gas it even feels like its being pulled down, and the front end makes a terrible whining noise. The only thing I did was put some differential fluid in the front, if I take it out of 4x4, I have to back up to get it to go out, at least on concrete, it doesn't seem to do it on gravel... What could cause this.

This is on a 2004 4x4 Ranger 4.0 automatic 5 speed tranny.

Its the 2 different size tires.In 4x4 they are turning at different speeds and they are "attached" the weakest link will blow apart so to speak so make sure the tires are the same size or something will break.Its no different than running 2 different gear sets.

Edit: it seems to work alright on dirt because the smaller tires are able to spin faster than the larger tires,on pavement that cant happen right.In the snow the back end will try to pass the front and from there it all goes bad.

I guess that could be the case. The front tires are 245's and the rear is like 255's., the front is Bridgestone Dueler A/T's tires, and the rear is regular Bridgestone dueler H/T's.

This defiantly seemed to be an issue. Would different tread effect it? I never knew that having two different sized would make this as bad as it seems. The tires even appear to chirp... I guess this could be it. I will check the transfer case. Would that make the front end drag and make that horrible sound as well? It really does seem like its dragging like a mad man... and the only way to get it out of 4x4 on concrete is to put it in reverse.

I guaranty its the problem.They will chirp and even a small size difference will do that,Even the same size from a different tire will be a different size.IE:265/75 r16 pirelli could be 32.2 and the same size in a toyo could be 32.8 and if the tread is worn differently that will be multiplied so buy all 4 tires at the same time and rotate them.If you can't afford new and have to buy used no problem just make sure they are a matched set of 4.

Change all your tires to the same size and manufacturer, even the spare. They all have to match or your going to continue to have problems. Make sure you do a five tire rotation too so that all the tires stay the same size. This is especially critical if you have locking or limited slip differentials. Different tire sizes or differently worn tires will burn the differentials out eventually due to the different rotational speeds of the tires.

why would you have 2 different size tires on a 4x4? and different brands and styles?? the owners manual specifically states that all tires are to be of the same size and load range.

I've changed tired since. The reason being is I work for a big construction company. I left my Ranger sitting at my house while I was gone on a job bid across the country, as I am a boss at the company, and job bids are important.

Some ass hole slit the tires on the rear, so I had to slap some on quickly as my ranger was needed for my nephew to drive. I own many vehicles as you can see, and I love my RANGER the most out of all them. In fact I'd drive it over any of them any day. For the record I had no issues with my differential, so as long as I was off roading with 4x4. Different sized tires are certainly not uncommon at all, and if they were going to eat the differential's up off road, or while not engaged, we'd have a lot of downed heavy machinery, because I am pretty sure the 4x4 back hole we got, which is a push button, would be eating through its differential on the front and back, as the tires are really really off on it. Anyway I got some Firestone Destination M/T's and they are awesome.

I found some pitbull tires as well. Just haven't gotten a rim or the lift yet. Camodown is going to have a twin white truck on here real soon

As long as the 4WD isn't engaged on road and the different sized tires are on the same axle, it would be fine. (small on one axle and big on the other).

The reason it isn't an issue off road is that there is enough wheel slip to prevent the lockers or LSDs from burning up (same for snow conditions).

With that being said, different sized tires on dry pavement with the 4WD engaged will burn up the lockers or LSD and thus the concern. Wet pavement could still be a problem and on hard dirt.

Sorry to hear about your tire slashing troubles and I'm glad to hear you have since gotten new tires. I hope the insurance was willing to cover them since good tires aren't cheap.
