To fit wider tires, is this safe?
I've put my back wheel slightly further back and used chain tensioners to hold it there. It's 14mm bolt on, thanks!

As long as you don't use the chain tensioners to actually tension the chain. Non-derailleur chains need to be slightly slack at all times. Since chainrings and rear sprockets aren't perfectly round the slack will vary as you need to confirm that there's still some slack at the tightest position. The ideal tension is where there's minimum slack at the tightest place, but that there's still slack.

Yes, by slack I mean visible looseness. Put your finger under middle of the lower loop and push up. There should be enough slack for you to push the chain up 1/4" or so. Now turn the crank slowly and you'll feel the slack change. Find the tightest place and confirm that you can still feel slack there.
