Helped a friend (Dylan) with his weld on kit. Started with some 15x10 soft 8s. Dylan ordered some custom rings from the same guy I got the Merc rings from. Pics below.
Set up a table to make it easier to work. I welded the valve stem hole closed and drilled a new one deeper into the rim make it easier to get to through the outer ring. Took the tires to Discount to dismount. Then back to them to have inner bead mounted they did it for free.
Weighed out 8oz. of airsoft BBs.
One done.
Dylan said the tires feel balanced better then they did before the airsofts. So when I get new tires for the Merc I am going to do the the same. I had the Merc wheels static balanced and it is ok but sucks sometimes on the highway when I hit grooves.
