Welcome to the forum
I build 4-stroke bikes in San Diego and I prefer the tensioner on the pedal drive side as well, if one is even needed.
I'm running 2.5" Maxxis Hookworms on my bikes and have no clearance issues as I have my wheels built to where they are centered perfectly. If the chain is gonna rub on anything, it's better on the stays than on the sidewalls of the tire.
You can use wider hubs and spread the seat/chain stays for more clearance or just run narrower tires if ya have to.

if it doesn't fit, make it fit! Beer is the answer....what was the question?

costs nothing, why don't people use them more often?
