yes, it works, and because the rod stays against the same spot on the tire it compensates for any bent rim or variation in the tire.
Well I did it, and you can tell me if this is correct. I think it is.
I bought a stickie tape from Hobby Lobby for $2.39 and a shower curtain from Wallmart for about $10.
I put the rod in the front of the tire just under the bumper bracket and rolled the car back to just about a 1/2" down from the rod touching the yoke.
Starting measurement on the front was 7 and 10/16's and 7 and 11/16's when the car was rolled back about a 1/2 tire.
Back to mosquitos, in Oklahoma, I heard 2 mosquitos argueing about who gets to haul me away.
On the porch, in the evening, we put a tub of HOT coals upwind of us & burned green Bitter Weeds, to smoke out the mosquitos. After going to bed, Mamma would spray the whole room with BLACK FLAG insect killer! (WHEEZ-COUGH) No wonder I tipe "funny"--
