Trailer Question

[oktige]

I see you guys with 18'' even 20'' wheels and tires on your trailer. Do you have to do anything special to fit the bigger wheels on?

My trailer came from the factory with 20's. I assume the axle had to be relocated to accommodate the larger diameter.

I think every dealer gets there own trailers from local sources...tige themselves dont do trailers (I dont think).
So like Timmys case, WWS ordered the trailer special and that manufacture has certain options you can get with their trailers.
Like for my Z1 I could have gotten the 20" rims etc but then it wouldnt fit in my garage so I went with the standard....but I did add the prop guard rollers, pin stripping, led package etc. as an option.
I would assume as well that they do something specific with the axles if you order it with bigger tires/rims. To get them to fit after the fact would take some work I would imagine.
Rock on!

Depends on how big the rims are as well. Some just make up for the extra sized rims by slimming down the tires, so the overall diameter does not change and nothing special needs to be done.

IMO, some very nice looking rims could be placed without having to make major mods.

But then you have to consider things like the load capacity of low profile tires as well.

The interesting part of using custom wheels is that I don't believe that trailer tires are made for sizes larger than 15". I assume then, that the appropriate car tire is used to get the correct carrying capacity.

[buffman]

Correct I still think they find a load range E though... at least I hope....

[TigeDuner]

I would to see a load range "E" in a 20" tire. It would be solid rubber.....

The 20" tire is being used on the rz4's. 18" tires on the rz2's.

This is from what I understand.

Don't ever use car tires on your trailer. They aren't made the same and will fail!

[kana12]

they do make load range d in 20's and that is all that you would need. actually that would be over kill for a boat weighing in at 4000 lbs. so c or d load range would be fine.

[chadster2]

about tires... how can you tell if they are too old?

[G-MONEY]

On a boat 4-5 year max

They make lots of sizes in load range E for 20" I think they make load range E all the way up to 24".

Question - why would a car tire fail on a trailer when the item being towed is the same weight or less than many cars? My trailer tires are 245/55/20's I think so they are a pretty tall tire.

I'm going through this right now... but I'm sending my trailer manufacturer my wheels and tires to build the trailer around them.

When choosing tires, make sure and use the plus sizing method. Most guys that are using 18's are using 255/45 R18

I'm putting on 19's and using a 255/45/19. The reason I'm using this size is b/c my trailer manufacturer's tallest tire is a 225/75/15 .... if you do the math, these tires are almost exactly the same height. However, the tire I'm using is slightly wider... so this will require a wider fender.

In all honesty, the wider tires aren't necessary. You can get by w/ a narrower tire so you don't have to adjust your fenders on an existing trailer. But you need to be concious of your offset's and backspacing. Your standard trailer wheels usually have a 0 offset. This is going to be really hard to find. A FWD + offset will probably be your best bet on getting wheels to tuck in correctly.

This tool is really great for comparing tire sizes, like when using the plus sizing method.
