You would not be doing that, you are replacing the 2 front tires because they are worn down more than the back ones, you would keep the less worn down ones on the back

Obvious solution since your asking is put one on the front and one on the back opposite side. 50/50 survivor ratio. 100% bad ride.

I can't control how good or bad a driver your BIL is. If a blowout is handled properly, there is still a large element of danger. If it isn't, you'll immediately either spin, or go directly off of the road.
Here's an OB thread on this exact thing: LINK

better tires go to the back regardless of drive axle

If they would be fine to rotate, then put the new ones on the front to attempt to even out the wear. If you don't, you'll always be buying two new tires and putting them on the rear.
I was told to put the 2 new ones on the rear.

This. Walmart lost a lawsuit in court because of this. That's the reason tire companies will put the new tires on the rear of the vehicle.

I'm not a fan of the two tire thing. I'm good about rotating my tires and like replacing all four tires at a time for wear. I know it's not always feasible but it seems like once you get into buying two new tires you will be constantly driving around with two new and two old tires.

I'm guessing most of their studies are done on passenger car tires with less tred depth than truck tires, so you have a valid argument. I just cross mine on the same axle and always keep the new ones on the back. I also have, on average unloaded, 600 more pounds on the driver's side (most behind the A pillar), so it makes a difference

If you are replacing the front tires because they're worn, why would you move the worn front tires to the rear?
The OP is a no brainer. You put them on the front. You need good tread on the front or else know you are you to do some hydroplaning.

Well, it depends if you're coming in under caution or green flag. Under caution four, not two, duh! But, on green flag definitely two on the outside to help in the corners. NASCAR 1001 baw!

Right side. That side wears down more quickly so needs new tires more than left side does.

New tires always go in the back. It doesn't matter if it's a front wheel drive or not. The weight at the front of the car will hold the lesser tread tires. The back end needs the new tires for better control.

completely conflicting answers. I put them on the rear because that's what he suggested, but it goes against what I've always been told.
Posted on 4/5/18 at 3:01 pm to Tic44
Its really simple. When the rear axle breaks free its harder to self recover. Also usually more expensive, due to higher speeds, so now they tell you to put new tires on rear. FWIW. I blame lawyers, bad drivers and poors. In that order.
I would put new on the front since thats 70%braking/100% steering. Making damn sure my bald rears didnt hydroplane on interstate.

The recommendation to put new tires on the back has been industry-wide (among tire manufacturers) for more than 10 years. The reasoning is the average driver can deal with understeer (loss of grip at the front) better than oversteeer (loss of grip at the back). While most drivers don't even know it simply letting off the throttle increases front grip because weight shifts forward as the car decelerates. This effect is increased when you put on the brakes. So the natural inclination of an average untrained driver (90% of them) is what helps recover from understeer. Oversteer is much more counterintuitive to correct and while many people in the snow/ice belt do it automatically in the snow/ice the speeds are lower and don't require the quick reflexes like it does in rain or dry conditions.

Also true in preventing loss of control from hydroplaning, the tires with the best tread need to be on the rear regardless of front or rear wheel drive.

Exactly, everything I said is irrelevant to where the driver tires are, a FWD car can understeer just like a RWD car. That said each vehicle will have different characteristics and performance cars will, in general, be more prone to oversteer since they are designed to have more neutral balance, a family sedan will be more prone to understeer. This debate comes up less often today than in the past since more and more vehicles have different sized tires on the front vs the rear.
