Always been my opinion that Harley Davidson has been making motorcycles for over 100 years, SO I tend to believe their Engineers and use the tire size they put on the trike when they designed it

I agree. I learned years ago that though i may not agree with everything hd does, their "engineers" know far more than I do. Ive done some things to my old shovels that were dangerous if not outright stupid.

Aftermarket companies are makin a fortune makin stuff for harleys thats unneeded.The one single thing thats made harleys unreliable from what I can see, is the owner. Fix it till its broke.

I think we all succumb to the temptation of " I can make it run better" And sometimes with disastrous results.

Seems like most folks agreed that the final drive ratio was not ideal on the early Tri glides and changes were made. The second design works great for the vast majority of us. It may not be ideal for someone who is on the Interstate 80% of the time or someone who is always on winding country roads below 65 mph, just enjoying the scenery. Tire diameter is just so easy to change. BTW, mine are stock size.

I'm wondering if an upsize to 205/75r15 would have a negative effect on performance and appearance. I am looking at Whitewall tires and most come in that size.

I checked tire dimensions. 75 tire is approximately 2 1/2 inches greater in diameter. "My thinking" is , since most trike tires are at less tan 24 psi the height of the trike will be negligible. The problems can be clearance with fenders. Keep in mind as the shocks flex you may come in contact with the tire. Also as your speed increases the tire will literally stretch ( think of a top fuel dragster heating up the tires, they grow almost twice in diameter, even considering the soft rubber compound). You may gain some bump absorption from the increase in sidewall width.
