So I have my project running and now I need a spare tire. The 9 in out back is a 5 on 5.50 bolt pattern and the front is a disc brake set up from speedway with a 5 on 4.75. Has anyone attempted to have a machine shop drill out a rim so as to have one spare? Can it even be done? Otherwise I will have to carry two spares or take one and have a 50% of making it home.
There was a line of wheels that had oval holes. The bolts fit the near end for 5 0n 4 3/4 and the outer end for 5 on 5 1/2. It should work OK I guess in theory, but I woulnt trust them in rough use or high speeds.
When I got my 39 16 years ago, it had the same exact problem. the previous owner had an adapter, Ford truck to Chev and carried a chev spare.
I use a ford alumiumn spare 16 inch tire and wheel. Have an adapter bolted to it so I have all my nuts handy. Wheel and tire a very light weight. Easy for an old guy to lift one handed.
Get yourself a common 6" - 7" wide Slot Mag with solid back. 14" or 15" will do the trick, just split the difference diameter-wise between front and rear tires with the spare tire size. If you're running a locker choose a tire size close to or the same as the rear tire. Easier on the locker and running different size front tires shouldn't create a problem as long as you have fender clearance etc. Drill the Slot Mag for the pattern you don't have. Strength should be sufficient. Back in the day a few FED fuel dragsters ran a dual pattern wheel with no probs. The pic shows the wheel you don't want. Note the casting voids between the lug holes. I'm looking for one more of these - 8" or 8 1/2" x 15" with about a 3" + backspace - from memory. I'd measure, but it's 26* inside the garage so I won't head out there for a couple of hours....
My suggestion would be to redrill your rear axle flanges to the 4-3/4 hole pattern. Problem solved with no wierd wheels or adapters.
my buddy did it to a late model ford aluminum space saver .....uni lug'd one pattern and added a second pattern....
yes i second this motion! chev 4 3/4 is a good pattern as wheels are cheaper sometimes as 4 1/2 seems to be the popular (desired) pattern.
The on this doesnt work is because the 5 on 51/2 has a HUGE center and the chevy wheel wont go on. Just use an adapter
thats what i was thinkin one is chev p***enger car and the other is ford truck too much difference in PCD not to mention center size, I think an adapter will be the only way
Go the other way. There is a Speedway kit that uses stock 5 1/5" rotors from a 73'-93' Ford F150 pickup. Then you can use Ford & some late Dodge wheels. Call Speedway and ask? Maybe you don't need the whole kit. Free call. Good Luck. Lucky667
