Just take an old kart tire you're about to dispose of, use whatever size hole saw you choose the OD to be and make as many as you wish. You'll already have the 1/4" hole dead center too. I bet you'll spend less for the hole saw than you would that many rubber/neoprene washers. -Alan-
cut tire apart lay on a 2 /6 use hole saw. not quite as easy as purchasing pre made ,works though. can also cut a few out of the side wall little harder and keep fingers clear is the main thing.Worked fine for me for 40+ years. I guess ya just need to know how to do it.
I am sure it takes at least two PHD's to mount a seat. For me it's not ordering part It's I want it right now part. I have shop full of tools. A 3/8's drill a piece of thin wall tubing of your choice, with the open ground to a sharp edge << in drill motor while spinning WaLa rubber hole saw of your own size . I have even used a empty soup can for cutting light foam for circles and relief holes. Karting started as DYI, now it's the credit card racer.Don't mess with something that is sub standard that could create a problem that you could chase all yr. Mounting a seat is not something you want to just cut tires up on because you don't have grommets

Guys, guys, guys............ I'm not saying that making your own is THE thing to do. I am simply giving an option for "do it yourselfers". I'm from an era of karting when you weren't always able to Google up your order of "readily available" items. It simply finds a use for useless old tires by simply using a little ingenuity. I guess such things are not appreciated anymore.
Curious if anyone knows where to get these in bulk? (Its for a non karting project at work and they are perfect for the application, need about 75 of them) Looked at McMaster, and didn't see anything?
