OK here's my pics . 1st 1 showing lego tires in front of wedico standard tire with a tamiya off to the right .
this 1 showing the standard wedico on my lowboy which works out to scale for 1:14.5 as per trailer specs
the lego tires under my step deck
the wedico's seem to work out as for scale on the bigger lowboys . the legos would work perfect If I where to build the 25 ton rogers I use to haul around which had 17" daytons
