Tires Minor 790 Wheel Rust

[hardtack]

I noticed on my new / previously owned 790 some minor wheel rust on the rear tires. Near a seam weld opposite the valve stems on both rear tires.

I tapped the valve stems on both tires and got a clear liquid. It was slightly tacky on the fingers after drying with a mild salty taste. Obviously the R-4 tires are filled. Check the fronts and they were not filled.

My questions are.

1. Is this a calcium chloride solution?
2. Should I be concerned about the rust?

Thanks.

1) Yes

2) It's just a rim. You can always buy another if ever needed. Cheaper than doing a fix for your rim.
