I wonder about the ET (offset) on a 5.5 x 14 steel rim by Fergat. 1969 Spiders came with these. Do you advice 185/70 x 14 rubbers?

Thank you

Thanks. I switched to 195/65x14 Falken. A little harder to park, but stick in the dry. Wet, I take it easy. The diameter is almost exactly the same with no clearance issues. The wheels are standard Alfa steel Graduate wheels.

Late 2000s came with 185/70-14. It's not a real common size nowadays, but you can find them, and is a perfect fit on this wheel.

Thanks, but what about the offset? 5.5 x 14 offset ?

Curious as the after market alloy wheels seem to have an offset of 23mm.

Offsets

The rim in the pic has a 38mm offset.

Just to be clear: Rim width (in this case 5.5") is measured between the inside of the flanges for the tire mount, not overall width. as the rolled edge adds about 1/2" to the equation.

If the seller simply gave you the "backspacing" (distance from hub mounting surface to the rims mounting flange (not the rolled lip) it would be easy to compute the rim`s offset.
