2021 Mojo trailer 15's or 18's??

[sandm]

Technically you would only raise trailer height 1/2 of 0.7”= 0.35”

almost every boat dealer out there told us 1.5-2" if you add 18's to the trailer and we confirmed this with a few phone calls and a couple of the websites show 1.5" for 18's under boat specs.
I am assuming that you also might need to factor in axles getting clocked a little higher for the rims due to width.

be careful using tire load ratings. our boatmate trailer has a max rating of 7500lbs on the sticker. each axle is rated at 3750lbs. this is below the ratings of all 4 tires added up.

I still think 2” is a high estimate. But the 18’s and 15’s are very similar in tire height.

yup. 2" is .5" on the high side but figure a tad higher and if you are sweatin .5" then go 15's. 1.5" is the standard that the 4 manuf. we were shopping came back with as the number to use and 2 other manuf. had 1.5 listed on the website.

it's actually kinda odd that the 2 biggest dimensions that most will shop are height on trailer and length on trailer. every manuf lists length in several measurements with/without tongue/platform but height is only listed on a couple of websites and not as descriptive if it's listed. we had to call.
not many houses out there being built with garages over 8ft high as a standard sans rv garages and 7ft is standard in some parts. would think this is just as critical as length.

Very helpful info! so, essentially 5600 lbs on a trailer that can handle 7500 should, overall be Ok... yes? 5300 lbs if we only end up using 500 in lead.. if that's all it needs.. we'll have to get out there and test it out..

Additional question to all of this: My truck is well within limits (9-10k tow capacity) but the rear tends to squat a bit. Not a lot, but more than I would like.

Has anyone had airbags installed to help with the squat at all? Liked / not liked? thoughts?

This isn't related to load or weight, but I imagine a larger tire also gives you more clearance between the prop guard and ground. I'm thinking about upgrading to 20's just to have the additional 2.5 inches of clearance. I'm worried I won't even be able to navigate the slight incline to get my boat on my driveway. My trailer is coming with 15's, but it's not a boatmate...it's one called Metalcraft out of SLC. I hope it doesn't suck.

dank,
keep in mind it's not just the boat weight. you have to add any options to the boat weight such as heater, upgraded stereo, etc and then factor in fuel, anchors, ropes, tubes, little bit of water that remains in the boat after each outing and on and on and on. so the dry weight of the boat can increase quickly.

one boat brand 10 years ago listed dry weight without towers

Rim size has nothing to do with clearance, it’s the tire height.

A low profile 20” tire could be shorter overall

Tire height dictates overall changes in height or clearance

Keep in mind, higher trailer height equals deeper you need to back into ramp.

Last thing I want at my ramps is a taller trailer

If it is in the budget I would go 18's every day and twice on Sunday if you trailer your boat. The 18s do not bounce as bad and you will run out of axle capacity way before you run out of tire capacity. They are make the whole set up look way better. We have 18s on out 2017 Mojo and we constantly get complemented on set up and rims are always specifically mentioned.

I am planning on adding airbags and an onboard compressor with wireless remote to my 18 F150 this spring.
