Any words of wisdom for dismounting and mounting tires on 10-spokes?

With the advent of improved equipment for dismounting old tires and mounting new ones, risk of damage to the wheels has lessened but I'm still paranoid when it comes to minimizing any possibility of damage during these operations and during balancing.  Anyone with experience in this regard? Any special precautions to take with the 10-spokes?  TIA!

i heard it may take 100 pounds of pres to get the bead to seat.

As long as the machine is set up properly and the operator is careful they are no different than any other alloy wheel. Original 10 spoke tend to be not so true though so depending on the tire machine a little extra clearance maybe required in the setup. No they do not take 100psi to seat or any where close to that. 20 to 35PSI would be normal to seat the tire on the wheel. Note; even being extremely careful sometimes the clear coat can flake off in spots on the outer edge of the wheel, like any other alloy wheel.

Rodney is most likely referring to 67 tenspokes . EdwardGT350 is referring to 66 tenspokes is my guess. There is more difficulty mounting the  66 style tenspoke unfortunately.

My problem with the 66 10 spokes is air pressure loss.  With radials, some do not always seat well on the outside rim bead.  Using a better installation soap seems to help.   8)

The aluminum can be porous also. I know some that solved the problem by carefully cleaning the inside rim and coating with a rubber paint like product. the good news is that here are more products out like that now then back then.  I knew of several over the years and they all seemed to be 66 wheels. No doubt the same thing can happen with the 67 wheels but just didn't hear of that same problem with those . Maybe others have.  For them that solved the problem on their 66 wheels.

15 inch ten spokes are easy.   14 Inch  66 10 spokes are a bitch to mount radials

Yes 67 15" 10 spokes. Sorry I missed the 1966 header topic.

The reason 66s are a problem is the bead on radials is a different angle than the bias ply tires and the long side of an original wheel is made for a bias tire bead.  When i go to the goodyear store they give me that look when i have an original wheel to mount

Did any later editions of the 66 10 spoke change the rim edge to successfully accomodate radials? 8)

Guess I've been lucky. I've had the local Goodyear dealer dismount/mount new radials on original 66 10-spokes twice and never had an issue.

Yes,  im going to send side by side compariosn pictures.  The  2nd generation wheel which is the best version compared to the originals in looks  has the upgraded long bead

I too had problems mounting my new good year 14" tires on my 10-spokes. 2 of the wheels kept going flat. I over inflated them and the problem was fixed. About 1 day later, I reduced to tire pressure to the correct psi and I'm good to go

two pics here.    first version wheel is a straight 90 degree long side bead with no safety bead.   Other wheel is 2nd version and the long side bead has an angle to it along with the safety bead.  this wheel will accept a radial much easier because the radial beads are at an angle whereas a bias tire  from the 60s has a 90 degree bead

Thanks for the pictures. Second version began being made when?
