GT 14 Tire conversion

Since its so hard to find 27x9.50-15 tire for my GT 14 thought I would investigate conversion sizes to give me more choices.

Here is a table of car tire sizes showing % larger or smaller.

Wow, you sure did a lot of research on this tire size business!

It will help a lot of GT-14 folks!

Great info... Have any of you tried putting a wider tire on the GT14?  Wondering how far one can go before the rubbing starts. I wonder if blocks that attach to the hubs exist hold the rims out a little farther. An inch or two would be great.
