Hey Joe, thanks for reaching out!
The Rambler ST145/R12 Radial Trailer Tire # TA89GR has a 21.3" overall diameter. You'll take half of that diameter and measure from the spindle up to look for fender clearance.
What is your motivation for upsizing your trailer tires?

Hey Jon, thanks for the reply. I am looking for a tire that is good quality with a higher speed rating than the usual trailer tire. Also I like D rating on this tire. I will definitely be buying a set of these ST145 Ramblers. Appreciate the info!
