14" To 15" TT Wheels

Clearance is your biggest issue...

Is there a particular reason for going from 14 to 15's?

Thanks!

My trailer is putting almost maximum weight on the 14" tires. I have already had one blow out with the 14" tires from going over a low curb at 5 mph. So I'm looking for "D" tires but only find them in 15" size.

You can find 14" in D range at tire rack,Northern tools and etrailer.com I have been looking myself.

I did the same on my small 5th wheel.....went from ST205/75-14s (1750#) to ST225/75-15s (2300#)....works well, rides smooth. I was also near the top of my weight, now no worries

I have looking at a few TT. some say get the double axle much better then single. Is the correct and is a single doable?

If exact same trailer came in both double or single axle, I'd buy the "double axle" trailer every time. Double axle rides smoother, less chance of blow out and more braking power. Win-win of many different fronts.

If you have the clearance, I would go to 16" rims. A lot more tire choices than offered in 15".

Also, the Kumho 857 is a load range D 14" tire

You'll get an increase in capacity going from 14" D's to the 15D's so I think it's a good move.
As always, I suggest Maxxis ST tires for 15" applications.

You really don't get an increase in capacity. More often than not your axle is rated to be right at the edge also. So unless you are upgrading your axles too, bigger tires will just give you a nice warm fuzzy, lighten your wallet, and do nothing to increase your capacity.

In other words, before you spend a dime, check your axle rating and see if there is reserve capacity over and above what your current tires are rated for.

All things being equal, the same trailer would not come in either single or dual axle. It's all dependent on weight requirements. The axles and tires that are installed are the minimum needed to meet the rated CCC. If in fact there was a choice, the dual axles are better more because they spread the weight out, not because of ride or blowout issues.

That said, up until my current trailer I've nothing but small single axle trailers with 13" wheels. I've towed all over the country with my trailers. Many years. Never a problem, and I notice no difference in "smoothness" of ride between single and double axle. Stay within weight ratings, keep the proper inflation, and drive no faster than the rated speed of the tire and you'll be fine no matter what size tire or axle configuration.
