Hey David! Our strongest ST205/75R15 tire is going to be the Provider item # TR20515D. This a load range D radial tire with a 8 ply rating and a maximum capacity of 2,150 lbs. The load range of a tire indicates its horizontal and sidewall strength. It has the highest highway rating of M which tops out at 81 mph. The tread depth is 9.8/32", which is pretty superior when compared to other tires. The added cuts to the tread push water away increasing your traction in slick conditions.

What kind of trailer do you have?
