Wiper blade question

[Uncle Vinnie]

Sorry, this might seem to be a really dumb question (I deserve what I get!).

Re: 98 S70 and '00 C70-

Both come with 21 inch blades. I like the Triple Edge blades, but they are
not available in 21's- 20 or 22 only...

I put 22's on each, the passenger side just makes it...

Any harm in this? The reference guide suggests 20 inch...

thanks!

If the wiper blade doesn't hit the windshield trim anywhere or at any speed,
don't see where it would hurt anything.

Thanks Dale, that was my thinking... just was wondering if there was
something beyond that, engineering wise...

The longer the blade the harder the wiper motor has to work.

All the best, Peter.
