How Fast Can You Go In 4WD--Seriously

Have a dangerous one-hour commute in a couple hours.

Since this horrible BFG/AT's have already hydroplaned on me in 2WD doing 40 mph--I no longer trust this wretched tire. The sooner I buy new ones the better. You can't make a case I was driving recklessly...the BFG has been unstable since the day I bought the Jeep. Worse tire I ever drove on...and I've owned a lot of trucks and tires..

Anyway, snow is heavy and visibility limited. Ideally I'd like the shift into 4-HIGH and maintain 40-45 mph on the interstate.

Is this do-able without damage to the NP T/C?

Thanks, Brent

I've had my jeep for 3 years on BFG A/T's and never had a problem with hydroplaning or instability. It doesn't sound like you were going excessively fast, but maybe there was so much water on the roadway that even at a modest speed of 40mph might have been too much for the conditions. Not saying you didn't experience what you say you did, just saying I've driven through some pretty bad rainstorms and not had any problems with handling. How much tread is left?

I've also driven in a lot of snowy conditions and the BFG's worked great there too. I'd say 40-45mph would be the cut off for driving in 4H without doing any damage. Remember to give yourself plenty of room to stop though as at that speed in those conditions, things can get dicey really quick.

Drive safe!

Thanks. I know BFG's are King...but I never had much luck with them. They are new. Extremely unstable tire so far, on dirt roads, mud, etc. Let's put it this way: In no time in the last month of ownership have I felt my BFG's ever bit into any surface at all. Every second they feel unstable. I rounded an icy corner at 3mph this morning and felt the jeep start to lose control. That is totally unacceptable for being in 4WD.

And in winter I drive like a granny. They are toed-in, taken down to 32psi for highway driving balanced...but I still need an alignment. I still need to buy sandbags--maybe that will improve it.

Maybe it's raw fear everyday that's causing me to bitch so much...is there a such thing as a "lemon" set of tires? I've never owned a set of tires that did so little of what I need them to do or expect them to do...I don't trust them at all and will sell them cheap on this list as fast as I can.

try 28 psi
it will also soften the ride
Turning in snow in 4wd in a jeep
takes alittle bit of learning to feel
your way around

I have heard of tires being sold that had "expired" ie, they were manufactured and sat in storage long enough for the rubber to go bad. Your tires should have a manufacture date stamp of some kind on the sidewall. It may be a date, or a code that you can look up. Not sure what else to say, other than all terrain tires are not snow/ice tires. those BFG's are supposed to give acceptable performance in ice and snow but they aren't really winter tires so they aren't going to do great on ice no matter what.

The 3 sets of BFG ATs (on 3 different vehicles) I've had all were by no means a "good" tire. My current set are noisy, chunky little beasts that will not be missed. The funny thing is, I like the Long Trails for our truck and the MTs are not bad. Maybe I've just had some bad luck with them. But 3 sets over 10 years with similar unsatisfactory results does not seem like an isolated instance.

Will someone else make some "pizza cutters" soon before next winter, before I will replace these please!
sorry for the rant

On subject: I've gone as fast as 85mph on 33x12.50R15 for several miles. But I would not recommend it unless you really needed to.

Back to the original question, I've gone 55 mph in 4 high with no damage. I just don't get people thinking that they are going to blow up their tranny & transfer case if they go over xx mph in 4 high. If it was not ment to go over a certain speed one would think Jeep would do something to restict it from going over that speed. Those warnings are for idiots who think they can drive in 4 low crusing down the interstate @ 100 mph.

4hi you can do whatever you like. I run full MT's around so it is a little different but I run my tires at 25 front and 27 rear. Rides really nice. Try airing down your tires to 25-28 psi, btw I never heard of anybody having a issue with BFG's. I run Dick Cepek, give them a try I love mine.

as everyone said, bfg is a great tire, very very rarely is there a complaint with the a/t.

definitely check the date, it has become a concern that people are buying tires that are out of date. tires have a shelf life of 6 yrs they are trying to say, after that they aren't guaranteed to be bad, but the integrity of the rubber cannot be confirmed.

the date is found in the dot number, lately i've seen two dot's on tires, sometimes you have to look on the inside wall, sometimes its on the outside wall. it will start with dot, and the last 4 digits is the date they were made. the first two digits is the weak they were made out of the year, the second two digits are the year. for instance, you may see 1808, that means they were made in the 18th weak of 2008, or may of 2008.

i've also seen idiot tire store workers air tires up to the max the sidewall says, i hope your tires aren't aired up to 44psi or something.

45 Miles.
Whiteout.
White Knuckes.
Blizzard.
2 Hours.
4-High.
30-35 MPH.
These Tires Still Suck A**.

Jeep went wherever it wanted to go; I just steered.
I thanked the Good Lord for getting me home---now into 2nd beer and getting dog kisses. Got red beans and rice in the fridge.

Have brand new 31X10.5 Hankook tires on the J10, second set, upstart Korean tire with extremely good ratings and quiet and actually grip the road and MONSTERS off road.. They are coming off this weekend. Hate to soil the J10 with the BFG's but there you go. Doing the old switcheroo.

Thanks for the expiration info and all opinions.

One more question--------I've had light vehicles like a small mazda truck and mitsu trucks as a teen but they handled the road.

Could I just be getting used to the lightest vehicle I ever owned? Is this some of the reason it has little control?

Good point about the weight of the Jeep, but a huge issue is the wheelbase. Wranglers have a tiny wheelbase and shorter vehicles are more likely to spin like a top. Another consideration is the LSD, if you have it. If you have the LSD, it will make it easier to spin the rear tires. I know I almost swapped ends a few times in my Jeep the first snowstorm. Drives much different than my old pickup. One more silly question: Are you sure your front end is engaged, I think YJs have a vacuum system, so if you have a vacuum leak, no 4WD?

hankook makes a great tire. i sell a lot of them, they are not an upstart, they're the 3rd largest manufacturer, and have been around for 60 years, this is what i was told by our tire rep.

That's a damn good question.
I notice a difference between 2WD and 4Wd---but it's TINY.
The dummy light on the cluster guage is the honest answer to you that I know I'm in 4WD...

The creators of this website were brilliant because the common probs (inlcuding 4WS vac) are thumbtacked at the top of this forum. I already have them printed out. When the sun comes back it's on the top of my list.
Thank you.

3rd best seller? Incredible. I know from what I researched before I bought a set was US Car Companies (Ford?) have started making this their off-the-assembly-line tire. Impressive.

Hate to say this is the best tire I owned...but it's the best tire I've ever owned..

Still reasonably priced and any online tire blog (discount, etc) they get great great word of mouth.

Since you are in the business, you probably don't want to badmouth a brand. My girlfriend wants to ditch her Yokos (it's time--tread is worn) and get Cooper or Hercules. I told her Don't Do It.
You can google 30 minutes and not find a damn thing out about Hercules. That in itself is disturbing.

My Hankooks are the best I've ever put on any Jeep. I've had the BF Goodies and agree with you about the suck factor on wet or snowy pavement. Hankook MT RT03's on there now go anywhere and respond great in the snow.

Best road tire I have used on a truck or 4x4 has been the Michelin Cross Terrain

I think the main problem you are having is adjusting to such a short wheelbase, personally I think all of the YJ's that I've driven handle pretty badly if you try and drive them like a long wheelbase truck in greasy weather. Even minor corrections can be too much and give you the feeling that the ass end is coming around. Relax the white knuckles and let the Jeep drive itself pretty much is what I've found works best, most of the time the best steering correction is no correction I've found. As a side note I drive my YJ about 80 miles a day to work, 45-60 4WD HI on the bad days in northern Indiana so I've got a pretty good idea hows things are in bad weather and I'm running BFG T/A's.

Let us know if the tire change makes a difference.

i had two toyota tacomas with Bfg's on them. real good for off road but not so good for the arizona highways. i put michelin cross terrains on the last one. the highway and off road was really good. a friend of mine, worked for the forest service in az, and had michelins on his work truck. lots of backroads and off roading. they literally came apart.....inside. no external failure was noticed. anyway one day i went out and found two of my michelins had deflated over night. i took them to be fixed. both had internal damage with no external damage. long story short....michelins are not meant for a lot of off roading. i was lucky as i could have been going up i-17 at 70 and had two tires fail at once. i'd vote against the michelins.
