Hi VM, with a new tyre the rubber is soft and you use a screwdriver to lift out the rubber and pop the hubcap in. But our wheels are 60 yrs old and are hard and cracking...... I got mine in, by spraying the rubber with WD40 and using a wooden hammer to tap them in.... worked... Get some pics of the work of art. cheers speedy
