ok, so ordering a new mojo - do I want 15's or 18's on my trailer?

I had 15"s (or whatever the smaller size was) on my 2018 - and now looking at a 2021 - I selected 18's.. but want to know pros and cons?

I hear that that smaller ones actually hold more weight (which, I will potentially be trailering with lead).. so that's a plus..

the downside is I just didn't like how it looked on the max (they looked too small for the boat)... so I ordered 18's but understand that apparently they aren't as good in terms of the weight they hold? How big of a difference are we talking about?

Am I making a big mistake going 18's?

any difference in the trailer "ride"?

thanks!!
