How fast with which tires?
« on: January 27, 2013, 10:24:42 PM »
I'd like to verify how fast one can tow most PUPs. The lower cost models with the smaller wheels are pretty much limited to 65, right? How about some of the "off road" versions with bigger wheels/tires like the Jayco Baja?

depends is the answer.
Depends on the tire itself. You need to read the info from the tire. it may have a speed rating printed on it or you'll have to go to the brand website and look it up.

Depends on which state/area you are towing in. some places have a MAX towing speed set to around 55 mph regardless of tire on the trailer. (California comes to mind)

As a side note you should not tow to the tires "redline" anyway. would you drive the truck at its redline all day long? same goes for tires. 

Now this is just a personal thought, but wouldn't an "offroad" trailer have tires designed for rough terrain and therefore tougher sidewalls for the rocks? rather then something that can go fast? isn't offroading about getting into hard to get to places...slowly? like first gear speeds?

Most ST type tires have a max speed rating of 65 mph, regardless of size. And small diameter tires (8" or 12") should not be towed fast because they really heat up at higher speeds. An 8" diameter wheel has to make twice as many RPMs as a 16" at the same speed and that causes more heat from road contact, plus there is less surface area to dissipate it. You would be wise to keep it well under 65.

There will be a speed rating on the tire sidewall, though it may be in the form of a code letter.

Thanks Ya'll. Texas towing limit is 70, Colorado 75. With the distances in TX the extra 5-10 MPH saves a good bit of time. (Wastes a good bit of gas too...) Sounds like the upgrade to bigger wheels tires will be worth it if towing a long distance.

Speed is in the mind of the beholder, lol.  Driving 60 mph equals out to about a mile a minute.  Sounds pretty fast to me and is easier on the pocketbook and tires.  I keep mine between 60-65mph and enjoy the scenery, even in Texas.

out on the open road it may feel like a huge difference..... but between 65 and 75 mph on 520 mile all day (8 hour) long drive with the vehicle held a constant 65 mph.... it only makes an 80 mile gain in distance....... stopping for lunch / fuel will have the same effect.

is that worth the risk of all that go wrong with high speed trailer tire blowout ? when things go wrong with a trailer at high speed it all happens real hard and fast.

slow down a bit.... it will save you fuel, tires, traffic tickets and maybe even an accident.

Let's see, driving 70 mph saves you about 15% in time over 60 mph.  So, you drive across the entire state of Texas from Texarkana to El Paso (about 800 miles) at 70 mph. It will take you about 11 hours and 30 minutes with no stops.  But, slowing down to 60 mph it will take you about 13 hours and 15 minutes.  Now add fuel stops, food stops and rest stops and that probably adds a couple of hours to either trip.  So, now we're at 15.25 hours vs 13.5 hours.


Now consider the increased possibility of being delayed due to a tire failure plus the increase in fuel costs.


Just what is 2 hours and 15 minutes worth?
