After failover process to tires so we wanted to store winter tires. Turns out they do not fit into the covers yet planned for their size.
To know that I bought tires for covers 13 to 18 "and for winter tires are 16 inches and really do not go. It's not just a matter of 3 or 4 mm, but several centimeters.
Suffice to say that those "normal in 18" is used the 3 other seasons have no chance to get into the cover.
The width of tire as the description.
If luckily I can find that are extendable a minimum, and in my price, I would consider another purchase.
