[DeTomaso] Hall Ultra Wheels

 Hall started producing Ultra wheels in 1981 through at least 2000 and there are several series, which is something people lose sight of. Obviously, the newer they are, the less possibility of stress-cracking. Some series may be more prone to cracking than others- I dunno. None are marked as to what series or date of production. You'd have to reply on a bill of sale with your car or photos from old Hall catalogues to find which series you have and approximately how old they are. 

And the only real way to check for stress cracks is X-ray which requires the rim-halves to be off the car. Any visible cracks are likely to already be leaking air. Airports have x-ray equipment as well as better equipped engine machine shops. The last replacement rim-half EVOD Industries made cost the owner around $300 and had ZERO guarantee for road use. Call EVOD for more info- they make the things and certainly have more trusted up-to-date info than casual posts on the Internet- including this one. Good luck- J Deryke

Everyone: thanks for the input. I am always amazed at the wealth of information on this board. It looks like I will be pulling and inspecting wheels this weekend! :)


I'd be curious to know how many Hall Ultra wheels were produced, and how many failed? Are there other owners still running these wheels?

I checked the wheels yesterday: no missing bolts, no visible cracks from the outside.  The tire pressure is okay.  I drove the car around town, keeping the speed under 60.  Is there a way to check for cracks without removing the tires; i.e. is there any value to inspecting the rims from the inside?  (I am in socal / ventura county: does anyone know of a shop with the expertise to evaluate the wheels?)


>>>You should pull the wheels and inspect them on the back side as well.



>Dave; what do you mean by "my wheels were not tracked"?


>>>He means he did not drive his car on a racetrack.   That doesn't really mean anything, since a racetrack typically puts less stress on a wheel than a pothole-filled road does (although it does put higher side-loads on it, especially when sticky tires are fitted...)
