What size tires for 18x5 fronts?

I have a few sets of front sportsman tires at the shop and trying to decide which to install on a set of 18x5 winlites. I’m leaning toward he 28x6? Any input?

26x6 is fine. Cheaper and lighter.

I have mnh front runner bias ply 4.5x28 on my 18 race star.

Bringing this thread back from the dead....

What size tire did you end up running? I'm in the same boat. Not sure if the 26" will look to small with a 29" rear that I'm running. I fear the 28" may look like balloon tires and may hit the fender due to the offset I'm running.
