75 Speed Limit - How Fast

[riltri]

We are heading to Utah from NC. I-40 most of the trip with speed limits at 75mph along much of the way. I do NOT go that speed when pulling. What do you guys do?

ETA: Carlisle HD Radials rated to 81mph

To bad that same person can't ride along with them to help them drive.

Very true fj12ryder! Had a relative earn a driving license there, and was no easy task! Funny...last time renewing my license here, they now have someone floating the room, to help you find your form and pencil, and will help get you to the counter, when it is your turn.:S

clearly the idea of driving being an earned privilege has now morphed into a right with no assumption of consequences or responsibility.

sometimes I think half the people on the road failed driver training.
And yes, previously in NC they will pull right onto four lane, go into left lane with no one in the right lane, and just sit there.
I have always wanted a huge light up sign in rear window that would
flash WRONG LANE

Thanks for that information. Guess it is not so much a right there as it seems to be in North America.

Running 20 mph below the flow of traffic in the right lane, basically setup a rolling road block.

Rolling roadblock? That's what that passing lane is for. If people would drive like they should, i.e. move over to pass and then move back over to their original lane, it wouldn't be an issue, but instead you have people that pull into the right lane and just sit there, even when they could get back over. There's your rolling roadblock.

Makes a person wonder how they keep the autobahns in Germany from being endless car wrecks, when you have people driving 100+mph and other people doing 60-70 mph. Oh yeah, they know how to drive.

I set the cruse control for between 65 and 70

I use a TT 500 (earlier version), on my 5’er. Tire temperature and pressure displayed. Drove I-90 across SD earlier this summer in 100-degree heat. No problems at 70 mph, load range E tires at 80 psi cold. “China bombs”, although new and rated at 75 😉

it was one of the greatest driving experiences I ever had going on the Autobahn. 99 percent of vehicles obeyed the laws and the whole concept of lane control was fully there. Funny that the fastest vehicles were the big BMW and Mercedes sedans, saw few Porsches driving fast. Maybe that has all changed. They do say when there are wrecks on that road, they are severe
I just wish I wasn't driving a rented Opel then that maxxed out at 95mph.

since this was a thread on fifth wheel speed, I think one issue that has been overlooked is ambient temperature. Pulling a trailer through California or NM right now adds quite a heat load to tires, and my understanding is heat is a prime factor in tires coming apart. TPMS systems tell you when air is low but not how hot your tire is. I wish they did both...

My little motorhome has door stickers saying 62 pounds in all six tires. Yet the tires are rated to 80 pounds. I put 70 pounds in each tire just to be safe and super high temps are not an issue on East Coast normally.
Is there a common sense rule where if it's over 90 outside maybe we should not do 75mph? Not that I would anyway...

Which TPMS do you use. Our TST-507-RV-6-C gives both the tire pressure and temperature....it is an after market system.

So you have driven in the Seattle area?

What do you mean Chris? The 520 and I90 on ramps to I5? Dealt with those for years, back in the 80’s and 90’s, now days I avoid driving through Seattle at all cost. Rather use 405 thru Bellevue. Last time I drove there was 12/31/2018 going to Snohomish to buy our 2016 Ram.
Last time needed to get north of Seattle/Everett, I turned left at Olympia coming north on I5, then took 101 north to Port Townsend, then ferry to Coopville.

Well when you consider about 90% of the interstate system is only two lanes in each direction, a rolling road block is a vehicle going significantly slower than the general flow of traffic forcing all to move to the left lane to get around them. If the volume of traffic is higher than moderate many will have a difficult time fitting into the left lane.
