following up on what ucodegen said… spend the time to learn how to put the tire cables on down here… So you can exchange them if they’re the wrong size.
We had the unfortunate experience of discovering that the cable chains we’d bought for a spring trip to Yosemite and Sequoia had the WRONG size in the box. Actually – only one of the pair was the wrong size.
It snowed while we were in Yosemite – and we had to pay extortion rates to get the proper size so we could leave the park and head to Sequoia. (Pass required chains.)
