MG MG Y Type - New Tyres and Tubes for the YA

Has anybody experienced problems when fitting new tyres and tubes? I have, every tube got a puncture within a few hours of fitting. The new tubes seem to be a lot thinner gauge than the previous set and puncturing on any little perfection on the rim. what is the solution?

What state are the inner parts of your rims in? Unless they are really smooth and totally rust free line them with Duct Tape or heavy duty carpet tape.

Might sound silly, but I had a similar problem with my MGB and its wire wheels. Ever since I taped the inside (1997) I havent had a SINGLE puncture. Now the tires are coming up for replacement due to age - ironic!!

Even if you think they are smooth - trust me - they aint going to be - TAPE THEM - if it doesnt work, I will pay you for the roll or two of tape that you might use!

I hand changed tires on my 1936 Ford, which had 16 inch rims and 1929 Ford which has 18 inch rims.

First, you inspect the inner rim and file down any asperity. Then you surround the rim with a rim liner (tire flap).

Coat the inside of the tire + of the rim with baby powder.

Using a tire iron, make one of the tire beads jump the rim lip.

Slightly inflate the tube so that it is not limp. Install the valve and slip the tube inside the tire.

Now comes the only really delicate part of the operation.

Moisten the still uninstalled tire bead with dishwasher liquid. (I find that Ivory gives the rubber a fresh country scent and leaves your hands looking younger.) Fit as much bead as you can by hand and ultimately by standing on top of the tire.

It's very important that you continuously ensure that the tube doesn't get pinched between the rim and the tire bead.

The middle section of the bead which is now under the rim lip should be pushed in so that the bead can temporarily take refuge in the middle, deeper section of the rim when the serious stretching takes place in a few moments.

All the while standing on the tire so that the bead you have pushed under the lip doesn't pop out during the stretching you are about to inflict upon the patient, you crouch down and take out the tire irons.

Again, it is VERY important that you continuously ensure that the tube NEVER gets even slightly pinched between the rim and the tire bead. If need be at this point, deflate the tube a little bit.

Use the tire irons (try to avoid plain screwdrivers) to wiggle the bead over the lip, inch by inch. Never make the tire iron go more than a quarter inch inside the rim before using it as a lever. Take your time. Be careful. Work as though you were trying to defuse a land mine. And use your weight to encourage the bead along.

It took me 4 evenings to change those 4 tires. It's exhausting work but they never deflated afterwards.

Duct tap or carpet tape is much easier. That and you can do that at the tire Shop while they remove the tires. By the time they are done removing you will have done a couple of tires and they can start remounting, inflating, balancing and putting them back on the car and you can probably drive out in less than 30 minutes all up.

Paul,

Half the fun is having trouble, sweating, cursing and swearing never to do this again! Don't reveal the easy solution right away! One must earn the right to brag and top one's brother-in-law when exchanging "war stories" in a half drunken stupor during the holidays.
