All ST tires are not limited to 65MPH. This only applies if there is not a speed rating in the tire description. My westlake tires have an L speed rating so are rated to 75 MPH

Here's a quote off the website: Trailer Tires vs. Passenger Vehicle Tires

Special Trailer (ST) Tire Speed Ratings
Industry standards dictate tires with the ST designation are speed rated to 65 MPH (104 km/h) under normal inflation and load conditions.

However Goodyear Marathon and Power King Towmax STR tires featuring the ST size designation may be used at speeds between 66 and 75 mph (106 and 121 km/h) by increasing their cold inflation pressure by 10 psi (69 kPa) above the recommended pressure for the rated maximum load.

Do not exceed the wheel's maximum rated pressure. If the maximum pressure for the wheel prohibits the increase of air pressure, then maximum speed must be restricted to 65 mph (104 km/h).

The cold inflation pressure must not exceed 10 psi (69 kPa) beyond the inflation specified for the maximum load of the tire.

Increasing the inflation pressure by 10 psi (69 kPa) does not provide any additional load carrying capacity.

How high speed?

The big dilemma for ST tire manufacturers was/is the lack of a speed letter designation for 65 MPH. Somewhere/sometime the Tire & Rim Association (TRA) stepped in and set a 65 MPH speed restriction on all ST tires not displaying a speed restriction of some sort on their sidewalls.

The big twist on ST tire speed restriction identification is now taking place and has a deadline (unknown to me). The US government has threatened foreign manufacturers of ST tires that they MUST include a speed restriction on the tire sidewalls or pay higher tariff tax fees. The most common way for those that must comply is to use the existing service description method. Although the service descriptions are not the official medium for displaying a tire’s load capacity on ST or LT tires they are allowed to be on the tire’s sidewalls. So All new ST tires from “over there” may have a service description such as this; 129/125L. The suffix “L” is the speed letter for 75 MPH. The 129/125L is a LRG tire. Each load range tire will have a different service description with a speed letter to display the tire manufacturer’s speed restriction for that particular tire. Any tires without a speed letter or other method of displaying their speed rating on the sidewall will still be limited to 65 MPH.

Here is one of the references I have on this subject.

IMO this is the best argument for buying the Good Year tire. If you ever have a problem with a Maxxis (even if not the fault of the tire), where do you go for service? I searched the Maxxis web site and the nearest dealer is over 300 miles away in Michigan. There is a Good Year here in our small town of 25,000 people and they have always provided good service for me. YMMV

Same reason I went with Carlisle. Surprise finding them a lot less expensive but having a great reputation.

When I put the GY 614s on my horse trailer I couldn't find any within 50 miles. Chances of finding them in stock now are probably no better. If I owned a tire store I'd rather stock the more popular tires. They probably sell 100 Michelins for every one 614 or Maxxis 8008.

I think you could get either one with free next day delivery from places like Discount Tire or City Limit Tire.
At some point during every day you suddenly realize nothing else productive is going to happen the rest of that day. For me, it usually occurs around 9 am.

If I have a problem with one of my Maxxis M8008s, I just put one of my two spare Maxxis on the ground and put the problem tire in the truck bed. My home town tire dealer who is a Maxxis dealer will make it good. The only exception would be if I were going one way with no plans of returning. In that case, I'm sure one of the towns that I would be going through would have a Maxxis dealer. Any city of any size will have a Maxxis dealer.
