I have a Subaru with 90k miles with Michelin Pilot Exaltos A/S tires. The tires have 51k miles on them and were rotated once at 20k. All 4 tires are just about worn out on the outside edge while the rest of the tires have a fair amount of tread remaining. I have never had a wheel alignment done on the car. In general, I keep the tires inflated about 1 to 3 psi over the recommended amount and have consistently checked pressure on a monthly basis. Would a wheel alignment solve this or can it be something else that needs looking into?
cause of uneven tread wear

This wouldn't happen to be your car....would it?

If I was you I would flip the tires inside out (dismount the tires, turn the tires upside down, remount the tires then balance) around 10-15k miles ago. Flipping the tires and keep pressure about 4-6 PSI above the placard, the tread will wear out evenly.
It's too late to flip the tires now. When you put on new tires, you need to 4-wheel alignment with minimum camber and minimum toe out.

I would start with the alignment.

The Pilot Exalto A/S is a uni-directional design, so he'd need to swap the tires from one side to the other. All-in-all, I'd say the treadwear is remarkable, as is. The tires have a 45K treadwear warranty and he's already got 51K out of them.
That said, I'd say that there is either an alignment issue or the tires have been subjected to harder cornering than the tire design is intended for.

I flipped 4 uni-directional tires on my E430 more than once (different set of tires) the last 5-6 years. I also flipped the uni-directional tires on my S2000 too.
After flipping, the tires were on the right would be mounted to the left and left to right.
I agreed that 51k miles for high performance tires such as Pilot Exalto is excellent, but he can get more out the the set if he flipped it once at the mid-life of the tires. The question is, does the cost of $10-15 to flip and balance a tire to extend the life about 5-10k miles is worth the money ?

Although my driving style is conservative, I have a propensity for cornering hard on highway on and off ramps. Maybe that is the reason
Anyways, I am very satisfied that the tires have lasted for 51k. I'll take it easy with the next set of tires when cornering.

I think it has more to do with the car's suspension geometry design. Some cars will wear the outer edge more than the inner and some will wear the inner more than the outer. All you can do is to flip it inside out to balance out the wear.

+1. I had subaru that did that too. I also like to corner faster than average people do.
Outside wear indicates positive camber. Consult the service manual to see if that's normal for your car, but since all 4 wore the same way, I have a hunch it's normal.
Toe would not cause the outside tread to wear faster as someone suggested
