I doubt you could fit 37" inch tires on the XT. It has lots of travel on the suspension, but it's got 32's on there now, and maybe you could go to 35's, but I don't see 37's working. You could contact Boreas and ask though about that and bolts, but that sounds like you'd have to change hubs/etc. It comes with a full spare though, so matching wheels/tires with the TV is maybe not so necessary. I get it that it would be nice to match, but then you might change TV's one day and that would be the end of that. For that reason and others, they don't make it a point to try and match, but maybe Boreas can share other ideas for you.
