I have some large off road Goodyear Sprint car tires tires with very flexable side walls. The rim is 15" in diameter and 18" wide. With the tire mounted the outside diameter of the tire is 33", The tread with of these tires is 18" and with the tire inflated the side wall bulges out to 21", deflated side walls are as wide as the tread 18". Will this size tire fit in the basic machine? Is there enough room left for the bead breaker to work? I also have some sports bike front and rears to be mounted, of coarse the No Mar system will work on those tires.

The Classic model Bead breaker clearance is 10 1/2". Jr. Pro and Pro model are 16 1/2" when used with black blocks as press platen. If the rim doesn't matter as much (race wheels are usually beat up a bit) you can remove the blocks for additional 3" clearance. That would give you 19 1/2" which would work for you. The Jr pro model has a standard schedule 40 pipe as a back post. Any pipe could substitute given unlimited beadbreak clearance. I would recommend our ATV beadbreaker for the soft collapsable sidewall and leave 5psi in the tire. Break the bead on the "Non- Offset" side of the drop center fo the rim. It is the most difficult with the slight taper. The wheel will be clamped in with the drop center toward the top of the rim while in the changer or the tires will never come off. They should be easy. We are getting ready to show a H2 tire change as a new video. They are easy as long as they are not Run-Flat type tires. Outside diameter clearance of the Jr. Pro is 35" and the Pro model is 42" when clamping the wheel into the unit. The beadbreaker throat clearance will be hindered on your 33"OD with the small rim. The Pro would work better for that but does not have an unlimited beadbreak clearance. We can customize a Pro model fo you and add height for more clearance no extra charge. It would just take a couple of days before it could ship out. We would need to provide you with a longer center post for the sportbike wheels to work with it. It would have enamel paint instead of the regular powder coat. Unless you wait a month before our next batch goes to PC.
