Due to repairs I have made to my van, my front end is out of whack. My new tires are just about totally worn out on the inside after 6 weeks. More on that in a moment since it's actually not so relevant but some will want details.
I will need to buy 2 new tires and have an alignment done at different shops. Should I get the tires first and drive the van to the alignment shop or should I get the alignment done first?
My arguments are:
Alignment first because the tires are so worn. Driving the van from the tire shop to the alignment shop will start to wear the new tires immediately.
Tires first because the alignment is not only to the geometry of the van, but also to the tires. If I have the alignment done with the old tires, then the wear will affect the outcome of the alignment job.
I guess this is more of an automotive chicken and egg and might not make any real difference but it is something I have wondered for some time and is more pressing right now.
Now for those that want details on which to base their decision:
It is a 1991 Plymouth Grand Voyager. Replaced the tie rods last year and had an alignment done, was perfect after that. But I noticed the control arm bushings were soft and the ball joint boots were torn. Replaced the bushings and it most likely just changed the camber from what was done previously. The ball joints didn't have any slop but because the grease was getting out, figured it was better to go ahead and replace them after nearly 20 years.
I knew I would need the alignment, I just didn't count on this much change to my alignment from replacing these parts.
