2) the front tires do 70% of your braking, so good tread means you won't lock up the fronts as soon and skid out of control

3) the front tires are more likely to wear faster due to turning, so it keeps good tread up there longer


and as for watching #2 on the previously mentioned link....if the rear tire lift as they call it, you still have the front to steer with & brake with. If the fronts lift, you have nothing to steer with, and braking response will be delayed since the rear brakes only do ~30% of the braking AFTER the fronts have been pressurized.

Again, this is what I was taught, and I know they have recently been putting out the stuff in the above link, and I think they are doing this because today's drivers are way way worse than they use to be (1/2 of them shouldn't even be driving)..................but you be the judge.....I'd rather spin out since you can control that easier than to slide uncontrollably into someone or something.

It does make sense, for a FWD vehicle. Also take note our XJ systems are actually closer to a 60/40 braking bias unlike newer systems which are more towards your 70% bias.
I do give you credit for posting up some very useful info that can be used for the GC owners as well. You can never have too much info.

70/30 or 60/40....very little difference......front tires lose traction and you've lost most of your braking and all of your steering ability


I know what I would do & what I recommend when asked.......but I also let them know not everyone agrees with me. Personally, I replace all 4 at the same time, but that's usually because they all need it.

It's your vehicle & your life...you know what you can & can't control and how well you drive......that's why I said "YOU be the judge.....", I'm just pointing out things others leave out.

Calm down and cool off there. Four tires are best, no doubt but dont go fly off the handle about other info posted.

All of them were a bit frightening as such as anyone knows who has had one, but I much prefer for a front to blow than a rear as it gives me more control.


I'm an old man and when it comes to tires when one goes and its not close to being new I replace them all, and my tire shop buys the take-offs from me if they are 50% or so tread.
