The Kenda # AM1ST86 ST205/75-14 load range D tire you mentioned is rated for a maximum of 65 mph.

If you're looking for a higher speed rating, and a C load range tire (1760 lb/tire) would work for you, I'd recommend the Taskmaster # TR20514 radial which has an 81 mph speed rating.

If you absolutely needed a D rated tire, you could go with a 215/75-14 radial tire that's only about an inch wider and 1/2 an inch taller like the Taskmaster # TTWTRTM2157514D which also has an 81 mph rating.

I've linked you to the tires I recommended, as well as to our Trailer Tire FAQ article, which I hope you'll find helpful.

The 7290 that you see is a casting number. It is found on AL-KO hubs that fit #99 spindles. I found that the bearings used are #28580 which would be the inner bearing and #25580 which would be the outer bearing. For the seal use #91030.
