Answer 1

I doubt it's your weight, you prob'ly just need more air pressure.  Check the tire for the proper pressure amounts and inflate accordingly.  Make sure too, that you have the proper size tube for the tire, that will make a big difference in how well they tubes work.

Answer 2

218 is nothing; i know people over 250 biking quite well.

start with new tubes, tires advised by a bike shop, inflate appropriately.

you will do well.
