Wire Wheel Valve Hole

Post by captain bobo » Fri Aug 10, 2018 8:50 pm

A few years ago I bought 5 wire wheels second hand as replacements for my rusting chrome wire wheels. I haven't been able to use all 5, because 4 of these replacements have valve holes around 11 mm diameter, suitable for the T13 valves on the inner tubes, but the 5th wheel has a much larger valve hole, so large in fact that there's a risk that the inner tube might "balloon" out in the gap between the valve and the edge of the hole. So i'm using a rusty chrome wheel as the spare.

I contacted a local automotive engineering company asking whether they might perhaps weld something to the inside of the wheel to reduce the diameter of the hole. They were adamant that welding was not suitable for steel wire wheels. They might be prepared to machine up some kind of part that would sit inside the wheel with a raised section that fits the big hole to reduce the size of the hole down to 11 mm. It's not a cheap option, and because it's only the spare wheel it doesn't feel worth the expense.

Questions: has anyone had a similar problem? How did you get round it? Are there perhaps any standard "hole reduction" products out there?

As usual I'm highly appreciative of comments and suggestions from forum members
Best wishes, Dave B

What you need is a 'nipple grommet'. I haven't seen these for years, but that said, these on ebay are the sort of thing.

Thanks Nick, I've never heard of nipple grommets before - every day is a school day. I've checked the dimensions of the items in the link you posted and they might just do the job. At the cheap price quoted I ordered them anyway; I might be able to enhance them for a better fit to my wheel.
Best wishes, Dave B

Any tyre fitting establishment might be able to furnish you with a suitable part?
