During "low" times, those types of things just become a matter of time rather than money for me. I may not always have the money "right now" to do some of the things I want/need to do, but that doesn't mean I'll always be in the same situation in the future.
With summertime drawing near, it's understandable that time and money towards the boat would be prioritized at the moment, but if you don't NEED to do anything with the VX for the time being, you're not going to be out much money if you don't use it very much, or for that matter, just let it set around this summer.
What does it look like long term over the next few months or so for being able to just wait and get new tires in time for winter?
And what size tires are you needing by the way? I have a set of all-season radials on my winter rims I've been considering selling because it was proven to me a couple of months ago that I need a more aggressive tread for the amount of snow I get here in the winter. I've been thinking recently about making the change to my summer setup, so I wouldn't be needing my current "winter" setup for awhile again.
