Maximum tow speed for 6500 lbs Toy Hauler with two axles

In addition, you'll find some states that have a max speed of 60 for everyone. If you want to really cruise, get a diesel pusher, set it on 85 and sit back and enjoy the cushy ride.

The speed rating on the tires sets the maximum. The brain may wisely lower that number.

If you're towing a toy hauler with a beefed-up 1/2 ton and Chinese-made ST tires rated at 65 MPH and going 75 MPH, please stay off the roads where my family and I travel. It's dangerous and irresponsible.

Hi,
Going to make a 2000+ miles round trip within 10 days time frame and wondering if there is any problem if I tow 75 mph provided road is flat, traffic is clear and normal wind condition.
65 mph sounded like a norm to most people and I like to hear from seasoned RVers.
Tow vehicle is Titan XD with Cummins 5.0 Turbo.
Thanks.

California has a speed limit of 55mph for trailers and towed vehicles.

Depending on the highway, they might allow up to 65mph even at the same posted speed limit of 55. But you don't want to know which is which as the state has the highest fines for traffic violation.

The most important consideration though is safety: for yourself, your family and other people.

You can go as fast as your little heart desires and be 100% responsible for the collaterial damage.

Your post reminds me of last year going up north on US 127 in Michigan. This guy with a TT blew past me like a house on fire. Got down the road about 10 miles and there he was, on the berm with two blowouts.

I tooted my horn and waved and continued to my destination without incident.

Speed kills. Not just people, equipment too.

Roll of the dice, 21, poker, slots, etc.. Same deal.. Will I win if I do any of those?? Dunno.. Maybe, maybe not.. Basically you are asking the same question.. ;)

No one on earth can tell you "sure, you'll be fine".. Or "Heck no, you'll end up in a burning pile of rubbish and kill everyone within a 1 mile radius if you do that"... :)

Most states have speed limits of no more than 70 mph.. Sure, there are those states that have no speed limits and all, but are you going thru those?

Anyway, only you know your comfort level and in "general" most OEM tires that are put on trailers are the cheapest and just barely clear the trailers load limit..

Personally, I'm comfortable with around 65 mph for hours at a time.. But, that's just me..

You can do whatever you feel comfortable with of course. And if that's 75 mph, well, there you go..

Likely including a MUCH greater stopping distance.

Leave a LOT of extra space.

Most ST trailer tires are speed-limited to 65 mph in their ratings. Depending on how close you are to the load rating on the tire you may be asking for a blowout.

I typically tow between 65-70 as that's the sweet spot for my drivetrain. I feel like 75 is pushing it for my rig, but if you have the hitch set up right and the rig is well balanced you maybe OK.

Also be aware that fuel consumption increases exponentially with speed because of the huge wind drag created by the trailer. No exaggeration, it may cost you a few hundred $$ over your trip more to cruise at 75 vs 65.
