Mounting HDAP Tires

5327 Views 6 Replies 5 Participants Last post by  ChrisR
I got a pair of HDAP tires for the rear of my X475. I grew up on a farm & changed lots of larger tires over the years, so I thought this would be a breeze.
I got the old tires off & the new tires on the rims fine.

The problem is that the beads of the HDAP tires are only 5" apart. The rims are 10 inches wide. How do I spread the tires enough to even get a chance at getting them to start holding air?

Are the HDAP tires really meant to go on narrower rims?

I have never run into anything like this before.

I installed HDAPS on my 345 a couple years ago. I had the same issue. Used a small tie down fabric strap in the middle of the tire and cranked it down to spread the beads. Worked fine but took a good shot of air and about 3 attempts to get it to seal.
