I'm going to be taking a road trip in my 2002 WRX shortly, but I just had a couple questions. My car has 28,500 miles on it right now, and the road trip would be about 3,000 miles. I need to put new tires on my car, and I know I should do the 30,000 maintence before I go. But do I have to? I could stretch and barely afford to do both of them before I go, but it would be much easier on the wallet to do just the tires before, and the service when I get back. Would I be risking any damage to my car by doing the maintenance when I got back (I'd have probably about 32,000 miles on it if I did the service when I got back)? Any help is greatly appreciated.
