The rim strip on the rear tires is ridiculously wide, or at least the oem tape is. That is due to the spokes being spaced very wide on the rear rim. You will want to replace the rim strips as I betcha the rims are rusty and as such have compromised the integrity of the strips. You must replace them.
That said, before I ordered an inventory of oem rear rim strips, I would use one of the aftermarket rim strips on the rear wheel then put the compromised oem strip over that. Yes I was running with two rim strips on the rear wheel.
Just a heads up is all.
Also, you might ensure that the installer cleans your rim thoroughly. Ask that they spray the inside of the wheel well with some sort of metal protector before they install the rim strip(s).
