If you have base model 17s my answer is also different as with 3500lbs of TC in the bed, (that’s a lot of **** in a Lance 650 btw, some spring cleaning and losing a bunch of dead weight might be a good anonymous recommendation…) I’d just find some newer takeoff 18s or 20s tires and wheels.
That solves several problems.
1. You get better load capacity tires than the milquetoast 17s which are their own story.
2. You get rid of the arguably questionable old tires and arguably questionable quality being Michiblows.
3. You can get a nicer newer higher weight cap set of tires in more desirable rim size.
4. You can get newer wheels and tires for less $ than just new tires alone.
