re that 'turned my 2.1 into a dog on any mild grade.'...

I like larger rear tires in 2WD ...
I can't say I've actually run a 27 X 8.50 with a 2WD 2.1 vanagon ..
but I run a 215/65 R15 in two of my 2WD vanagons...

I measure the unloaded diameter at 26 inches..
and in either my 87 Wolfsburg running a 1.9 wbxr on Digifant EFI,
or my 85 Adventurewagon running a 2.1 on Dijiget EFI ..
both of those vans do just fine on any mild grade.

I do spend hours getting them to run as perfectly as they can though,
for what they are.

I know a guy with a 2.1 wbxr syncro 7 passenger ..
runs 27 X 8.50's all around...
and they 'look' very just right for a 14 ...he seems happy with his power.

YMMV as they say !
