Question:
Can I replace my Load Range C tires with these D-rated ones on my 2016 Casita 17 foot travel trailer? 205/75r15 tires
asked by: Linda
Expert Reply:
That’s a smart upgrade, Linda. Your Casita uses a 3,500-lb axle with a 5 on 4-1/2 hub pattern, so the # MXS39FR is the correct match, not the # MXS77FR (this one is 225/75R15 with 6 on 5-1/2).
The # MXS39FR is the same ST205/75R15 size you have now but steps up to a Load Range D (2,150 lbs at 65 psi) for stronger sidewalls and better highway stability. You’ll notice a smoother ride and less sidewall flex than the original Load Range C tires.
How many miles do you typically tow in a season?
