I am currently running a Dunlop front tire on my 2015 Triglide Dunlop size 130-90-16 model D40-4F. What size and brand rear tire can I replace that with

 

Looks like this tire is a possible replacement for the OEM tire:

DO a search on trike tires and i think the Avon tire (AV71) has been replaced by this new version.

 

I would look at the Avon Cobra Trike specific tire. I'm running one on my 2016 and am very happy with it.

 

I have been told to put a rear tire on the front because of the deeper tread depth it will last longer

The Avon Trike tire comes with deeper grooves than the stock Dunlop. It's about the same as a rear tire.

 

There are other considerations. Internal construction determines rotation direction, made to withstand braking forces on fronts, acceleration on rears, so when putting a rear on the front it's usually recommended to mount it in the reverse rotation direction. Do this, and the rain grooves are backwards. Lot of people have done it both ways and say they had no problem. I don't have a trike, but do have a Harley sidecar rig, similar stresses since it won't lean into corners. I put an Avon trike tire on the front of it.

 

I've run several rear tires reversed in the front. They are much better than the stock front tire. However, I like the Avon trike tire even better.

 

You will not find a car tire that will fit the front with out major modes . The old taxi tire some used is not made anymore.

 

Putting a rear on the front of a trike was the conventional wisdom , until Avon came out with the Avon Cobra Trike front tire.

now the Avon Cobra is the way to go.
