Thanks guys.

I measured the tread depth of each summer tire and they were all looking very good. I did notice that two of the rims looked like they lost balance weights, so I decided to drop off all 4 sets of tires/rims at a shop to be balanced. As for alignment, I don't think I'll require one. The X handled like a dream all summer/winter.

Oh, I will be replacing my swar bar links, that shouldn't require an alignment afterwards, should it?

Thanks again
