80 MPH, 85 MPH fast enough?

There are states that have up'ed the Speed Limits to 80 and some 85 MPH. You know drivers will encroach even slightly higher speeds.

I for one do not drive a Truck and 38' Triple axle 18,000 rig down the road at 80 MPH. I am comfortable at the 65 - 70 range. Enjoy the ride and enjoy the scenery along the way.

I remember a FT a while back commented here about 2 X 2 X 2. If I recall it was On the road for 2 hours, in by 2 and stay at least 2 days.

Now that is the way to enjoy a trip. But these fast highway interstate speeds will mean more accidents in my opinion.

Our home state of South Dakota is one of the states that went to 80 MPH. The summer months they carry a ton of RV'ers along the interstate system. I-29 & I-90. Sturgis has the 75th Anniversary this year and estimates are there will be a million visitors.

I don't know, just my opinion but I am not sure 80mph on a system designed for slower speeds with lesser traffic is asking for trouble.

I do not want to push my rig that hard or the tires or anything else. So I guess stay over in that right lane and LOOK OUT for the fools who think that 80 or even 85 are not fast enough.

I just keep in the right lane,65 mph. Here in Texas, where the limit gets up to 80, traffic is usually thin enough that I'm not a problem. When I'm down to 4 wheels, I'm flyin' low with the rest,

I drive a MH, an old truck, and lifted/modified jeep. Only time I can see 80mph is downhill with a tailwind. 60-65 works fine for me, thanks.

Most trailer tires aren't rated for those speeds.

Many, at least my 06 Ford, has an electronic speed limiter set to 75 MPH. If I wanted I could pay for a new program to over ride the limit. Not sure why I would need. Bumped up against it a few times. Wasn't much fun at that speed, can't imagine what 80 and above is like.

Also coach tires usually are not rated above 75 MPH. You can bump up against the limit for a bit but sustain high speed for a couple hours and you might have a tire failure of some type.

There are stretches of I-10 where it's 85. Like posted before, 65 in the right lane and don't sweat it... I've been through there with no problems. I always tow at 65, but bump it up to 70 when passing slower traffic, just to get out of the way in a timely fashion. Safe travels.......

Good ole Utah has 80 mph on the interstates. The fools just raised the limit to 70mph on the freeways in the Salt Lake City area.

Most of the highways have a design speed higher than the posted speed. I expect that the interstates which have the 80 mph speed limit are either at or still under the design speed. Curves that do not meet the 80 mph speed requirement are posted at a lower speed.

Newer car designs also mean that higher speed limits are possible.

Was in SLC when they were discussing the higher speed limits on a talk show. Some bureaucrat was proudly proclaiming that the number of speeding tickets had gone down since the speed limit was raised.

I think it could be described as: "A crash is a sincere attempt to slow down!"

The Michelins on our Magna are only rated for 75 and I don't think there are many (any) rated for higher speeds! I'm pretty sure the gearing on the Magna will let it reach 100 (and the engine is capable of it) but the towed is only rated to 65 so I hold it to somewhere close to that. Oh yes a ticket for 67 in CA (12 over the 55 towing limit) will cost you $469!

I donít understand what is going on in this country!

If you agree or not, according to the EPA we have an energy problem, i.e. Every year the EPA demands higher fuel mileage on new cars. But now we have a 80 or even 85 MPH speed limit!

Do I see something wrong here? Isnít this a conflicting message?
