Question:
I have a Travel Trailer that I believe uses this rim after searching Dexstars catalog, but need confirmation as the current marked tire width seems bigger. The tires currently mounted on the rims are ST215/75R15 108/103M. We need a spare. Thank you for any help!

Hey JS thanks for the pictures! A ST215/75R15 radial trailer tire fits a rim that is 5" to 7" wide. You would be more than ok mounting it on a rim like the Dexstar 15" x 5" Rim item # DEX54FR you were looking at.
This rim has a 5 on 4-1/2 lug nut pattern so you'll want to confirm that's what your travel trailer has as older ones would use a 5 on 4-3/4 lug pattern. I have linked an faq article below that will show you how to measure your wheels.
We do not have a wheel and tire combo with the Dexstar Rim item # DEX54FR you need. The best option for a tire is the Provider ST215/75R14 Radial Trailer Tire item # TTWTRTM2157514D. It is a load range D tire with a 2,200 lbs capacity and has a top speed of 81 mph.
What travel trailer do you have?

Hey JS, how did things turn out with the Dexstar 15x5 rim for your travel trailer? Did the 5 on 4-1/2 lug pattern match up with your setup? Your update could make it easier for others checking their wheel fit.
