Hey thanks for the links.
Got any ideas where I can get some light weight 14" rims for a Geo Metro?
You have to match the load rating of the wheel to the load rating of the
tire. Plus thrust force that the wheel is subjected to while acceleration
and braking which is calculated by the total weight of the vehicle divided
by two which may be apply to one drive wheel.
In a very light weight 16 inch rim, my specifications for the wheel came to
the actual weight on that wheel plus another 20 percent for static load
which came to 2600 lbs rating. The thrust rating of 200 percent of the
actual weight on that wheel which came to 4000 lbs.
These had to be custom made by CenterLine.Com which makes racing type wheels
by spinning a aluminum sheet into a wheel. They are not cast. I would had
to order 100 wheels to get the price down to $500.00 each back in the 80's.
Just to tool up for one set would cost about $10,000.00.
The wheel I had to choose, has 5/16 inch thick center plate that is full
welded to the rim which has a thrust rating of 4000 lbs.
You also have to match your axle and bearing set to the thrust rating.
When my EV was built back in 1977, it only use the standard set of bearings
and axils. They only lasted a year, where the bearings grind a groove
through the spinals and axles surfaces.
