Default Trailer tire size increse

Guys would it be okay go from a 205x75x14 to a 215x75x14 there is plenty of room and my wheels are good for either size. Would there be any advantage or disadvantage to doing this? The reason I'm asking is none of the local suppliers have the USA built Goodyear Endurance tires in stock in the smaller size currently.

The 215 is 0.39" wider and 0.58" taller than the 205. There should be zero problem switching between the two, as long as you're running the same on both ends of the axle.

For those that don't know: 205x75x14
205 = tread width in millimeters
75 = aspect ratio (side wall height percentage of treadwidth) so 205 x .75 = 153.75mm sidewall height
14 = wheel diameter in inches

Is it a single or dual axle? I highly doubt there will be any issues- BUT those are always famous last words on THT.
If it is a dual axle, measure the current space between tires that you currently have and then deduct 1.16" That will tell you the new spacing between tires.

I just did the same thing on my Ameritrail trailer. Called Ameritral and asked what would be the largest size I could use and it was the 215, really fills in the wheel wells. Bought the Endurance on line for $107.25 plus free shipping and got them in 2 days. Most shops will mount for $20 but I have a friend with a tire changer. The Endurance is rated at 65 psi, 2250 per axle and 87 mph. Had 2 blow outs last year on 3 year old Chinese junk coming and going to the keys.

There is currently 8 inches between the tires. Think there would be any issue?

this is only true when the axel is not a free spinning spindle, meaning the axel connects to gears and drive shafts. its not the ideal situation, all it would do is cause a tire to wear a little more!

Maybe so, but my OCD would be running on overdrive.

As long as you have clearance to fender and in between tandem tires (8” is plenty) you’ll be fine.
Take a peek on inside of tire and make certain there is plenty of inner clearance too, but from what you’ve described there shouldn’t been an issue.
