Here are some picts of how close the tire is to various parts of the swing arm. This is a shot of a 2002 LT
swing arm and these tires are new Bias Ply Bridgestones
Notice the rubbing potential as shown in Pict 1 is not really on the side of the tire due to the cut out of the swing arm.
The real potential for rubbing (ask me how I know) is on the edge of the tire just to the side.
Picture 2 shows just how tight it is and you will see residue from a recent tire rub. I was running 3 year old Radial
Bridgestones and the tire delaminated in 3 spots. As the tire expanded it just ran into the swing arm. I tried to get
warranty since the tire had plenty of tread left and they just looked the other way due to age.
As some pointed out leaving off the spacer could place the tire even closer to the swing arm. Running the correct
pressures is also important but I would suspect the tire would rebound to a round shape since it would rotate 3/4
of a turn before it passes by the swing arm.
Glad to see you are seeking the correct tire as there is little room for error in this area and I would not even want to
talk about the results of a blow out due to a tire rub!!
