How To: Installing 9:00-16 tires on CMP wheels

[colin jones]

That looks great Bob and a nice simple idea. Again it shows with a little combined effort and idea the most difficult job becomes not so hard at all.
Fantastic, I will remember this system should I ever come across this job.

I agree with you Hanno the Restoration forum does do that.

Now for the "moderators"...... what does it entail......

How much technical skill is needed??

......since I am on the forum site almost daily...sometimes more .....I wonder if I could help out.

Cheers

Great show chum !

Bien fait !

Great idea Bob.

My Fordson WOT and its new STA 10.50 x16 tyres wish you had come along earlier. My neighbours ears would have been spared a lot.

I have decided that my difficulty mounting the Michelin LTX tires on CMP rims was largely due to more flexible sidewall and bead structure. After a couple of false starts I added an auxiliary pusher made from short bits of 2x3 and 2x4 lumber powered by a C clamp to push the bead around the curve of the rim. Once round the curve, the cross pusher worked fine to take the tire further down the rim ready for the tube and flap. The other half of the rim went on exactly as expected, Put the rim in place, tighten the rim halves together and add air to ease the tire into place on the rim. Photos attached show the wood addition to tooling, the tire half mounted and the finished product.

Also comparative photos showing the LT235/85R16E LTX against the STA chevron tires in 10.50-16 size and against Michelin XL in 9.00-16. Although the LTX look small in comparison, they are rated to carry over 3000 pounds which is actually slightly greater than the rating of the 9.00-16 CMP tires (although they were run over capacity for some of the 15cwt trucks).

Well at risk of repeating what may have already been said...in my experience the biggest pain was getting the 60 year old tires off the rims. I used a backhoe; put the stabilizer leg down on one side of the tire and pushed down the tire with the bucket and then cut the bead with a torch. Once practiced it was easy to do. To put the new US style tires on I had the rims turned down about 1/16 inch all the way around the inside. This removed most of the pitting, left a smooth surface so a minimum of "SNOTH" was required and hopefully made it easier to remove them again some day. I will be trying this method again this summer but will have the rims sandblasted once I get the old tires off...BP

Hi Bob C.

Excellent thread, concerning Bob P. the tire removal issue yes the problem of 1st time tire removal has been discussed at length.

My point concerns the subsequent removal, how well you clean and paint the rims will make all the difference in future removals. Once the rims have been cleaned down to bare steel and well painted, my experience has been that the tires can be removed with just the tire irons from the tool kit. Average time 1/2 per wheel. There are some tricks which will try find the photos to explain.
