Do you need to change all 4 tires on 4WD if 1 is flat?

So my friend works at a tire shop and had a flat this morning on his 05 F150 with 4WD. It turns out that there is sidewall damage and it can't be fixed. He is now convinced he has to buy 4 new tires. I've heard of needing to change 2 tires at a time for AWD vehicles but never all 4 for 4WD vehicles. Is this right?

It is recomended to buy new ones....but its driveable if you have a tire that is the same diameter.

as long as the tires are the same actual diameter, within some small percent, it's not a problem to only change one.

Even if they are not the same it's really only an issue if you have a locker.

Yep, happened on our AWD mini van all the time (we abused the hell out of that mini van). If your tires are warn enough, a new tire's diameter is too big. Your only luck is if there a used one around ruffly the same size. And in that case, your lucky to get the same tire brand.

Is this a serious question?

No he doesn't have to change all 4 tires. He can buy one tire to match the others. At most if his tires are worn he should change 2 and just make sure they are on the same axle (new tires on the back and old tires on the front or vise versa). The only time that the diameter of all 4 tires matters is when it is in 4 wheel drive and that is only for reduced traction situations where the difference in the tires is lost to the loose traction and not sent through the driveline causing trouble.

So tell him if his tires are good then just buy a new one to match the old in type and size. If they are worn then buy 2 and put them on the same axle keep the old one from that axle for a spare and go on with life. The only reason to buy 4 new ones is if he needs 4 new ones or is changing tire size like going from 32's to 33's.
