Not that I an expert but Pat your formula is kind of wack, but thanks for the motivation.

If you go to regular tyre shop website like Bridgestone and grab a tyre they will show you the range of wheel/rim width recommend use the tyre on i.e. 165 R can go on rim 4" - 5.5".

The rolling radius seems to be what people are more concerned about for the low ratio geartrain on the older morris especially.

Hi Paul

Yeah I've certainly got something wrong there.

... I've done some more searching and here is something more reliable:

Divide the rim width by a factor to obtain the proper tire section width for the wheel. For tires with aspect ratios of 50 to 80 the factor is 0.70. For tires with aspect ratios less than 50 the factor is 0.85. For example, if your rim width is 7.5 inches and you want a tire with a 70 aspect ratio, divide 7.5 by 0.70 giving an answer of 10.7 inches.
4
Convert the result in inches to millimeters, multiply by 25.4 and round down to the nearest odd multiple of five. For the example, 10.7 times 25.4 equals 271. This would be rounded to 265, the nearest odd multiple of 5. Aspect ratios only come as odd multiples of five, such as 195, 205 or 215.

Look for tires with the section width and aspect ratio you calculated on the diameter of your wheel. If the example wheel is 16 inches in diameter, the desired tire size is 265/70R16.

Make a good Tui add anyhow. Could always send an email to NZ LTSA you would expect some conservative response from them as they should have transport specific details!

the book that i found is basicaly the same thing in a different form. it has the plates showing the exploded veiw as in this one but i think in more detail, but the parts list is a little more detailed in this one it appears.without going through the one on here and comparing with my one page for page so to speak, i would guess they would be fairly simmilar and could differ outwardly for the different markets maybe. and here i thought i was on to something good.

dropped the good lo light guards and grille panel of to the blasters today. will pick them up on friday as hes a liitle busy and im not in any great rush.oh yeah, i opened up a bourbon aswell and then i had to drink it. lifes tough .

You are onto something good :-) I have been searching for years for parts books, for the early Minor especially, but any parts book is very useful for the great exploded illustrations. I once worked for BMC Canada in the warranty claims department and it was there I learned to use the Parts book more often than the Service Manual.

Still busy stripping my Morry to get it to paint. In the meantime I am trying to get the parts that are missing or needs to be replaced - what a list. A Morris samaritan just came to my rescue and are sending me a fuel refill pipe. There are still good guys around!!!!

started to adapt a fiat stalk unit ( lights/wipers) to the morrie coloum, and i think it will work well. had to ream out the hole in the unit a little so the morrie coloum will turn freely and make a plate to weld to the morrie outer coloum so as to bolt the unit onto. i was going to use a 323 mazda/ford telstar coloum but if i can pull this one off i can use the original mounts ect.

Yesterday I gathered the materials to make door pull straps for my 1952 MM.

A few weeks ago we had unusually high temperatures (80s F) so I took it for a spin, washed it and put away.

Sprayed the shuts on my doors then bolted the sump back on my motor and fitted it in me travlr. Starter is all bolted up and all the stuff on the block, then I went out for a blast on me Buell, I'll bolt the head and bits on tamorra.

Well, I had a bit of time today as it is a holiday here in Bermuda, so I put on the new bumper Chrome Trim and newly chromed over-riders on the moggy. Then a new bonnet opener clip was installed as mine broke from I guess; age. She is really starting to look like my old girl again. I was going for the 50's retro look and have made modifications over time, and so decided to rebuild the center console originally there and a friend of mine has offered to reupholster the completed bits in the traditional black tuck and roll look. it really will look like it came with the car.

Anyhow, I hope to update soon as I progress a bit more.

Took Jethro for a 45 mile round trip today to see if everything was working OK.
Apart from having to top up with a small amount of coolant and a slightly leaking sump gasket the car ran really well considering it was a very hot day!
Had a real struggle getting used to the gearbox and having to select gears very carefully and slowly compared with modern cars. Finally got the hang of it after about 10 miles and was changing gear up and down with no noise and using the semaphore trafficators at the right time! Got loads of smiles and waves from other drivers.
A very enjoyable run and hopefully the first of many.

I hoisted my motor off the floor, turned it upside down and lowered it onto the bench. I fitted a 3/8ths BSP fitting to take the ancilliary sender for my oil temperature gauge into the side of the sump (oil pan), got a few newish gaskets and cork strips and bolted this all onto the block liberally coating everything with Permatex black. I've already fitted the rear seal kit, the one that bears on the flywheel flange, in my hope to finally fix the oil leaks from the rear of the motor. The sump then got a quick coat of paint and that was it for the day, anyway its 27 hot degrees C. outside so I took off for the beach. Shoreham by Sea - very nice!

Ah yes, these cars do love to leave their "calling card" in the parking spot don't they! Good luck with the seals, sounds like you're on top of it, sounds too hot to be working on the car.
