First, it won't matter if you get the brakes and rotors later.
Second, I would shop around and find a shop that will sell you a 3 yr or 5 year alignment. At the NTB near me an alignment is 79$. A 3 year alignment is about $130. NTB will do an alignment ANYTIME I ask during those three years. It is also transferable if I sell the vehicle for another vehicle.
The reason I do this is that early in my driving career I bought a set of 60K tires. They lasted 30K. They wore out because I didn't rotate them, didn't balance them and I never had an alignment. I learned the value of 1) rotating the tires, 2) balancing them and 3) doing an alignment. I live in an area of the country where we have snow and salt that creates potholes. I took it back once after hitting a pothole and it was way out of alignment. I now take it in for an alignment every 3 months or when I know I hit a pothole. My tires last a LOT longer.
If tires are $400-$600 installed and I can double the life of the tires with alignment for $130, then it saves me (half tire price - alignment price) or between $70 [200-130] and $170 [300-130]. I drive 20-25K per year.
If you take this approach, you just take it back and get another alignment for "free" when you get the brakes and rotors. It is also great when you buy new tires, you just take it in and get an alignment w/the new tires!
BTW, aggressive recommendations are 1/yr or every 15K miles. Least aggressive approach is to watch for:
- your car seems to be drifting to one side, even when you think you're driving straight
- your steering wheel vibrates
- you are driving straight, but your steering wheel isn't centered
- you notice tire wear
What I believe based on experience is the by the time you notice any one of these symptoms, you've altered the tire pattern on the tires and they don't drive right which leads to lower fuel mileage, shorter tire life, more frequent alignments and problems that can't be fixed with alignment or balancing. YMMV (LOL!!!!)
Hope this helps!
