So, out of laziness I gave my front wheel to a "tyre expert" to fit the new boot.
Muppet well and truly screwed it up, did not seat it properly, trapped the innertube and damaged the rim tape. Bloody thing nearly came off the rim and the rim tape shredded and came out. Don't know what state the tyre is in.
I have a spare tyre (the old one), and a spare innertube. what I dont have is a new rim tape.
For me, getting a new rim tape is a 3 to 4 week process. (one of the joys of living on a rock in the sun).

Is there anything intrinsically wrong with bodging it and using duct tape or Gaff tape?

My guess is I will need a new tyre as well, the bead is ugly, so I can get a new tape then, so it would only be temporary.

For mounting tires, I use baby powder inside the tire before inserting the slightly inflated tube, and ArmorAll as a lubricant on the tire bead. Don't know how it affects overall life of the rubber. I lay the wheel on a piece of plywood on the floor, and I find I have to use my knees to help hold down the tire as I work around the rim with the tire irons making sure the tube is out of the way with each new pinch. The last couple of pinches are the most likely to nick the tube. Don't know what I'd do if my knees were bad!

For my land speed racers, fitting tires on tubeless tire rims are So Much Easier and no chance of pinching a tube. And with the ArmorAll, they just about mount themselves. We just don't want to even think about the what-if's that can happen with a tube at 150 mph.

I have also noted that most new tubes today just do not maintain their air pressure like the old tubes did. Are there some tubes that do hold their air?

Good and earned advice Gordon.
I tried rim tape on some ductwork and it failed. laugh

If you decide to fit it yourself, get some proper tyre soap and lather the tube and the tyre in the stuff.
I have come to like using Talc (baby powder) on the tube and a rubber lube, like P-80, on the bead of the tire. Pre-inflate tube with just enough air so it will still fold in half by its own weight.

I agree--just a bit of pressure in the inner tube and then use talc powder--on the inner tube and the tire.
Been doing it that way for 60 years without a pinched tube.
And no water in the rim to turn it rusty!

Do not use duct tape as a rim tape if you will be riding in high temperatures with a heavy load. My wife and I crossed Utah in July on a MSS Velocette with lots of luggage. Experienced numerous flats due to duct tape cuts. Got to where we could replace a tube in under 15 minutes but not fun in a hot desert with no shade available.

Wouldn’t you get water in there when you have been riding in the rain or riding through any standing water?

I worked as a mechanic for a few years, as well as servicing and repairs we did tyres for bikes, cars, tractors... anything type of tyre that went on a run/hub.

Never nipped a tube once I started using the tyre soap method... but you use what you have to hand. I use tyre soap even since I changed career, I don’t have talc powder around the home.

And my bet is.......they were actual cuts....running parallel with the rim on the inside of the tube. Absolutely no other way it could have happened except for the exposed sides/edges of the duct tape. I never believed it until it happened to me.

Worth remembering that rim tapes are made of rubber and are pretty cheap.
I keep 2 or 3 18" rim tapes in stock because it is frustrating if you need one and have to wait for it.
18" tapes will stretch OK to 19", 20" and 21" rims.

Thanks for all the input.
Interesting about duct tape cutting the innertube. I think I will try electrical tape, seems a safer bet. Will only be temporary anyway.

Count your blessings!

last time I checked they sold baby powder at Tesco.

Now having had a few experiences with my lack of understanding of how the English use nouns like bonnet, mudguard, paraffin but the one that really caught me out was "cot".

Once (and only once, as sometimes I am a fast learner), I booked a room at a UK hotel. It was for three full sized American lads. You know 6 foot plus and a "svelte" 17 stone. Asked if they could put a cot in the room for the third lad. When we checked in we were curious why the lassy sorting out our keys, was acting a bit odd. She had a hard time containing her giggles. It all became clear when we entered the room to find a "cot".

Now is talc, perfumed and then called baby powder or do you have another moniker for baby powder?

Have seen people use Duct Tape. Can't say I ever heard of a problem. But I can see it might cause a problem with a slightly underinflated tube.

I remember when living in UK I ran out of talc powder and went into a chemist (US: drugstore) to get some more.
I asked the assistant for the biggest cheapest container of talc powder that they had and I didn't care what perfume it smelt of.
I got a very strange look in return!---she obviously thought that I was going to use it in some sort of perverted ceremony----which in a way I guess I was!

Water doesn't normally find its way onto the inside of the rim to rust it.
Think about it--you have the inner tube pressed hard against the inside of the rim and the tire bead is forced against the rim lip.
Rusting is IMHO caused by the use of aqueous solutions to get the tire bead to move into the correct position in the rim on fitment.
Just my two cents worth of course.

John-- the UK usage is that the perfumed talc powder is called "talc powder" whereas the nominally unperfumed talc used on babies posteriors is called ":baby powder".

I laughed with your description of the use of the word "cot".

In the reverse direction I was working as a young development engineer in UK in the automotive industry.
We were doing a project with a US company based in Detroit.
I visited the US company to discuss the project.
This was in the days before CAD etc and about 8 of us were gathered around a large horizontal drawing board discussing the drawing on the board.
I suggested a mod to the component and said " I will show you what I mean---we need to remove this line and move it across. Has anyone got a rubber?"
There was stunned silence and then a big fat guy from the south of US said in a drawl" What the hell do you need a rubber for at a time like this?"
We had a few laughs and a few beers about that one that evening!

The only baby powder I have lives in the shop for the one purpose of powdering up tubes. I don't know where one gets P-80, but NAPA sells a big jug of a product called RuGlide for a reasonable price. It really helps the levers slip on the rim while mounting a tire. laughing
I have used duct tape for a rim strip in an emergency. It was a lot of trouble to remove the tape PO used on a few occasions. It is a lot simpler to cut through if you use rim locks.
However, I always order a new rubber rim strip when I order the tire and tube.

you can make rim tapes from old inner tubes.

A.N. Other site, the Canadian owners have a list of "hate speech" words, converted to asterisks before posting. Can't post FAG when talking about bearings ...

I use P-80 when mounting tires. Bought a case of bottles of it years ago. Kept a couple of bottles and supplied others on the forum with the rest of it.

It's also very good for preserving fork gaiters.

Right on. I had an old rear wheel with an old "Made in England" Dunlop tire and inflated tube sitting around my garage for God knows how many years, and when I finally got around to dismounting it, it still had around 30 psi in it! If there are modern tubes that hold air like that, I haven't found them. I have to add a few pounds every few weeks.
