Tire circumference chart for Dunlop Tires mounted on the designated rim size.
Tires were mounted using a tire band, no valve core and beads well lubricated.


Adjusting tire sizes once mounted
It never fails when I buy a tire, it's the wrong size. This has frustrated me for years! Especially when I have this chart above and that's what size they SHOULD be!
Well, now I have a couple of tips to solve the problem! You should now be able to have any size tire you want.


--------------------------------------------------------------------------------

Tires too big
Make sure you've used the correct rim size.
It doesn't make sense to mount an 8.00 on an 8 3/4" rim and expect it to be 34"

Step 1: Pre-heat your oven to 350 degrees.
Step 2: Remove the valve stem from your tire.
Step 3: Insert tire into oven for 10 minutes. This should shrink the tire approximately 1". Sometimes more, but usually less.
Step 4: Remove tire with oven mitts, either insert the valve stem and dunk into cold water for about 10 minutes or set in a cool place with no valve stem and cool for 30 minutes.
You WILL notice a size difference when you remove the tire and think you 8.00 is about 33", and it COULD happen, so be careful.


--------------------------------------------------------------------------------

Tire too small
This one isn't as bad, we could use the oven trick but....
Fill your tire with about 20 lbs of air and check the size. If it grows 1/2" then let it sit there overnight. If it doesn't grow that much, put another 10 lbs in it and set it in the sun for a couple of hours. Usually what I do is set it in the car with my tape measure and check it during the day. Once it's grown 1/2" to 3/4" bigger than what you want, place it in a tub of cool water for about 15 minutes. Then let your air out and see what it comes up to. If it's too big by 1/4" or so, let all the air out overnight.

From the information I recieved from QRC is that it is the same as one heat cycle.Except for the fact, the more you heat them, the harder they get.
