I currently have ST205/75R15 on my trailer. How much wider are the ST235/75R15 tires? I need to know before I order. Thanks

Your ST205/75R15 is going to be about 8" wide while a ST235/75R15 is 9.3" so you're looking at about an extra 1.3" of width (cut that in half if you're trying to figure out how much clearance is needed).

If you don't already have your eyes set on the larger tire size I recommend checking out the Taskmaster ST235/75R15 Radial Off-Road Trailer Tire # TA45RR since it has a load range of D (2,910 lbs at 65 psi) and an impressive 87 mph speed rating. The aggressive tread design also means it will perform better than a standard tire is you end up needing to tow your trailer off the pavement.
