Tonight I was window shopping for trailer tires
. Mine are about six years old, looking great, but entering the zone when you worry about oxidation damage. Fortunately, we're up in Denver where there's about one-quarter less oxygen
available, so I might get an extra year or two.
Checking Discount Tire for what's new in trailer tires
, I noticed one with an "R" speed rating, then another. All of them were R-rated! An R-rating sets a speed limit of 106 mph.
In many threads here, I've read that trailer tires
aren't safe beyond 65 mph. I've tried to honor that most of the time. My wife sneaks up to 70 often, and I worry a little. But just like every other mile, our Scamp
16 tracks obediently behind us like a good doggie.
We're about to take a long tow down Southwest to the Grand Canyon and vicinity. It will be very tempting to run 70 mph on the Interstates. Especially since our new tow car, an Audi Allroad, almost doubles the available power from our old Forester. How should I feel about that speed, which is still 36 mph below the tires' rating?
I'm not suggesting anybody rive any faster than they feel comfortable. But now I wonder if trailer tires are as much a limiting factor as I've been told?
