I hesitated to respond, because one member here kind of took offense because I always keep repeating how happy I have been for 20 plus years with foam filling my front tires on both my BX and my B2910.
Small front tires do not cost that much to foam fill if you find the right supplier.
Foam filled tires so not come off the rim, do not need air pressure checked, do not puncture, and if you find the right place, they can adjust the foam to mimic tire pressures, more or less.
Just something to keep in mind. I have been happier than the happiest camper over the years...something to consider...
