I have a 2013 Coleman CT270BH that came with 14" rims with ST205/75/14. Can I safely upgrade to 15" rim so that I can put LT tires on her without any issues? Will I need to do an axle flip to get additional clearance? Currently there is 6" of clearance between the axles and the top of the tire and the wheel well. Also is there a standard bolt pattern for the wheels? I have looked on the website, in my paperwork and everywhere I can think of to find out the bolt pattern. The only place I haven't looked is the back of the wheel.

I changed out my wheels and tires after I bought my 2012 Northtrail FX235 from 14" to 15". All you need to do is check to see if the tire size you want to go to will fit and that the wheel bolt pattern is the same. I was not comfortable with the tires that came on my trailer. Weight rating was barely enough and they wore out very fast. I did a lift and upgraded to the highest weight rating and tallest tire that would fit. Saves your bearings and gives you piece of mind. I found my wheels and tires online for a great deal.Look online on how to measure your bolt pattern. You may or may not need to do a spring over to get the clearance for new tires and wheels. It depends on how big a tire you want to fit under your trailer.

Are there any 15" LT tires with a D or E rating? You might want to skip 15" and go with a 16" rim. Good luck.

If you are contemplating a rim upsize, going all the way to 16s can make a lot of sense.It appears that you have plenty of room to do so.You only need 1" spacing between the tires. And 3" from the top of the tires to the wheelwell.Going to 16s is easiest if you presently have 6 lug rims... Not likely if you now have 14s.I was in your shoes on a previous TT. I eventually got to 16s after spending a LOT of money on incremental upgrades. I hade 3500# axles with 5 lug drums. I found that 6 lug drums could be swapped straight over. They used the same bearings. New drums were suprisingly affordable.They even came with new bearings. I made the swap at bearing repack time to make it easier.There have been some that have been able to find 16" 5 lug wheels. They were not around when I did it. I also haven't looked at the total advantage/disadvantges of that approach: How widely available are they if a replacement is needed? What is that cost compared to the cost of doing what I did?If you can go to 16"s, it opens up a vast array of tire choices, that may well make any cost for the upgrade doable, or even pay for itself overtime.

Looking at the coleman site, it looks likeyourtrailer weighs about 5800 pounds or so ready to go camp. Figure 5000 to 5200 are on the axles.If you have 205/75-14, they are likely on rims that are 5.5" wide, and have a five hole on 4.5" bolt circle. If you want to stay in 14", the, for instance a Kumho 857 load range D tire would have at least 1874 pounds of capacity, and as much as 2100 or so per tire. That leaves a healthy reserve ( assuming I am right about the weight of your trailer ).You could also do a 15x6 rim, and still be on a five hole with a 4.5" bolt pattern. In a 15", something like a Continental Vanco 2 would work.EDIT, PS, whatever tire you choose, do your homework and make sure you are choosing a tire that is compatable to the rim width. Tire rack is one good place to compare those kinds of specs.

Didn't think about going up to 16's. I know the tire choice increase with each size. The extra clearance will help when boon docking in the Rockies. Already lost a leveling jack last week. I am sure I can do wheels and tires for around $600.

There are 6-lug and 8-lug trailer axles that use 16" wheels. Most trailer axles that use 15" wheels are 5-lug, on 5" or 4.5" bolt circles.

You need too measure not just the clearance between the wheel well and the tires, but also between the two tires. And make sure you measure all four tires there's a possibly that there could be a difference at each one, if there is it won't be much but it could be enough too cause a problem. If you can do it this may be the best thing you can do that trailer.

Does the axle have brakes on it?

If it has brakes, you have to keep in mind that a significantly taller (and heavier) tire will cause the brakes to be less effective than the stock height tire. Tire diameter is a lever arm on the brakes, and weight is an inertial force that also affects the brakes. Taller/heavier tires/wheels are harder to stop.

I would not put considerably bigger/heavier 16" wheels and tires on an axle made for 14" tires. The braking performance will be practically non-existant after the tire/wheel swap.

I would go only slightly larger in tire diameter and width, on either 14" or 15" wheels.

i ordered continental Vanco 2 215 /70 r 15 load range D in an LT rating tire .
2271 # weight rating on the sidewall .
106 mph speed rating
manufactured in the czech republic .
fits on the standard 5 bolt 4.5" zero offset steel rv wheel .
ordered from tire rack on monday , arrived on wednesday at my local tire shop and installed on thursday .
this is a tire made for european vans such as the mercedes sprinter vans .
215/70 about the same diameter as an 205 /75 r 15 ( 1820 # rating )

Looks like I have a lot of research to do before I make up my mind. Leaning towards the 15"s

You can find LT tires in other than 16" rim size but you have to look far and wide. One member posted the Hankook tire he found but I'd have to wonder about availability, especially if you got a flat that couldn't be repaired (not necessarily a blow out). The availability of that tire cuould leave you stranded for a while.

I did get the same Hankook LT tire for a spare. Discount had these for me in a day. If it came to being stranded for a week, I'd definately throw another tire on and live with it till I got home. I also carry a plug kit and have an onboard air compressor. While maybe not the perfect solution it is a workable one.

I stand somewhat corrected, I should have said the LT in a 15" load range E is very difficult to find. I did the search for LT's in a 15" but when I was looking, I was looking for something that would be suitable for my TT. The load range D tire would not be adequate for the job with my TT. So, if ones TT is doesn't require the the higher capacity load rating then of course, an "LT-D" in a 15" wheel will do the job. However, anything requiring an "LT-E," you will be hard pressed to find in a 15". I could be wrong on this as well but that was my experience. I was only able to find the E in a 16" and 17", if there are other sizes I didn't look as anything larger than a 17" woudl be impracticle for my TT as I would imagine other trailers as well.
