Tire size

Single axle trailer, 1988 pro-star Tire size now is 205-75-14 with a load rating c I would like to go to a 215-75-15 .

Has anyone ever done this before? I am looking to gain some towing capacity

That tire would be a larger overall diameter on the 15" than the 14" wheel. If you go with a larger diameter tire you need to cut down on the aspect ratio of the tire (the middle number) to keep the same overall diameter.

215 is millimeters wide of the tire.
75 is 75% of the width in sidewall height
15 is the diameter of the wheel.

The larger size will raise your trailer about 3/4". Maybe that's good, maybe not.

I don't think you'll find a 215 75r15 in a "trailer" tire you will need to goto a 225 75r15, either 15" you choose will be wider and taller than the 205 75r14, besides having to purchase new wheels you might run into clearance issues. Personally I would find a D load in the oem 14" size and call it good.

I ran into this same situation couple weeks ago when I put new tires on my trailer. One side was an original from 1995. I bought some Carlisle's because I didn't want to go through all the hassle and have some clearance issue that caused more damages by going with a much "cooler looking" 15" wheel. And full size tire. Then I was told the Carlisle's I bought were crap and the tread seperates from the tire often. And i'm about to drive my new carlisle's 2000 miles. So maybe I should stay out of this thread.

I would recommend going to a tire shop or new car dealer and having nitrogen put into the tires, nitrogen maintains psi better doesn't bleed down and the tire runs much cooler thus not increasing psi while driving due to heat, there's a reason why military aircraft, commercial aircraft, most first responders and nascar puts nitrogen in tires. I wouldn't worry to much about your new tires all trailer tire manufacturers have had tire blowouts, tread seperation etc., but thats usually on a tire thats been neglected, dry rotten or just plain old. If you get a flat with nitrogen filled tires no worries simply fill with regular air, on your trip take a look at the tires from time to time to make sure everything is ship shape.

HERE IS SOMETHING THAT IS HELPFUL!!

http://www.miata.net/garage/tirecalc.html

PUT YOUR ORIGINAL/STOCK TIRE SIZE IN AND THEN PLUG THE NUMBERS OF THE NEW TIRE TIZE IN AND IT COMPARES THE WIDTH AND HEIGHT DIFFERENCES IN EACH TIRE. PRETTY NEAT LITTLE TOOL!! IT SHOULD ANSWER YOUR QUESTION

They are close in size but few manufacturers produce an ST215/75R15
