Alloy rim specs
I like to know what the width and off-set is of standard light-alloy 15' Ford rim, used on the '93 Econoline E-150.
I also want to know the threadwidth front and rear of this truck.
At the moment a have 255-70-15 tyres on both axles, this size makes the speedometer very accurate, very close to zero.
This set i'm gonna use in winter time.
For the summer time, i have figured out, two combinations:
in front 255-55-18, and at the back 285-50-18 or,
in front 255-60-17, and at the back 275-55-17,
both combinations are on the back with a inch wider rim, to compensate the tyrewidth.
Who has expierence or can tell me more about these combinations.
Thanks,
Rudi

Do you need a set of these wheels?

No i don't need another set, i have already a set in use.
I need the specs for calculating, so that i can order the right 17' or 18'rims.
I want to correct the threadwidth, so that the ouside of the wheels is in line.
I have the idea that the difference is about 2.5', but i would know it for sure.
Maybe i order the rims with my specs, or blind rims, i have done that before.
So if you or anyone else can tell me what the threadwidth is?
Greetz,

PS what is the BSM-size?

You want to know what the BSM size is, right?
Well look at it this way:
The mounting surface of the wheel can optionally be on the centerline of the tire (zero off-set) or on ether side of the centerline (positive or negative off-set). The Back-Space method is to determine tire clearance and fitment. As the BSMeasurement gets smaller the ‘track-width’ of the vehicle gets wider. A very small amount of Back Spacing can shorten wheel-bearing life. To measure the BSM lay the wheel with the outside facing down. Lay a straight edge across the tire mounting lip and measure down to the mounting surface. Don’t confuse Back Space with Off-Set.
Rudi, in your case, the distance between the outer edge of the rim and the mounting surface of the rotor(=discbrake) or the brakedrum (rear) is listed in this case as 4.5"; this equals 115 mm
This is the size I mentioned to you in another thread.
Or in plain Dutch: DSM is de afstand van de binnenrand van de velg tot het pasvlak met de trommel/remschijf.
Sorry about this guys, it's gotto be clear

I happen to have the same wheels; could you tell me where you found those comprehensive specifications?
Would appreciate your source, if it is on the web.
Thanks,

Outside edge of one tire to the inside edge of the other tire, both where they touch the ground, that should be near enough I guess, give or take a few millimeters.

I got the specs from an ad on ebay. There is a guy there who sells a lot of OEM take offs from conversion vehichles such as tires, wheels seats and so on. I knew I had seen the specs in one of his auctions before, so I looked him up again and he still had a set of this type of wheel for sale with the specs posted. Cut and paste and there you have it.
