IMHO...
Just because a tire or any component has a higher speed limit...does it
mean you 'have' to go that fast...
High end street racing tires may have a 200MPH speed rating, but they
also perform well at 55 MPH...
If there is any question on anything and there is a better choice or
option albeit a bit higher in price has me go to the better/best one
with little to no decision time required
All wheels sold in the USA has a DOT mandate to have their spec some
where on the wheel. Ditto tires
Most are on either the interior (hidden by the tire) or back side
Some are painted/screened on, others stamped into the metal or cast in
Just like sizing things just barely or slightly below the actual usage
will have a constant worry. I'd just get the best can afford and biggest
can afford...but know that I'm in the vast minority here on this forum...
