Suggested speed towing 5th wheel

[mahdi]

Cliffy is correct. I did all that and still had 3 blowouts. Best is to safe and in right hand lane.

[rskeans]

62 mph

[mahdi]

Yes. In the past year before the blow outs, I did Seattle to Maimi in the winter. 65-70 most of the way except west Texas I was at 80 in the desert part. Now I think 62 and slow is good.

I have a TS36rlso triple axle. Use to pull 70 to75mph. However, found out trailer tires rated under 70 mph. I just cruise 65 mph. with my F-250 4X4 6.0L.
Also, I stop about every 2hrs or so at a rest stop to let the engine cool down and along with the tires. Everybody needs a rest!

How about the speed limit?? Just an idea.

[GBS]

Most car speed limits are some or a lot higher than tire limits (and personal mpg limits)!

Hi all.

I have "G" rated tires with 110 psi max. pressure, is it o.k. to run at that pressure?

Or should I reduce the psi by 5 or 10?

The weight on the axels is 12000 lbs give or take.

If that's their max, then it's perfectly safe. However, max pressure without max weight could contribute to poor tread wear. There are tables that can be used to tell you that XXXX weight equals XXXX PSI in the tires.

As you add PSI then the tread block pushes out while the much stiffer sidewalls stay the same. The idea is that you adjust pressure to equalize the load across the tread face.

Back in the tire business days a BF Goodrich trainer showed me a great way to determine exact air pressure without scales and charts.

Ready for a trip weight wise air your tires up to their rated max and tow it about 30 miles. That will get the tires nice and warm.

Go to a parking lot that's flat, straight and hopefully empty.

Use a white tire crayon that you can get from a parts store to color a line about 2" thick across the tread section of one tire. Put a bit of masking tape on the side of the tire in line with the crayon line so that hopefully you'll be able to see it easier when you stop.

Pull forwards about 50 feet staying straight as you can. Now, look at your line.

Chances are the center of the line will be gone. Color it back in, let 5PSI out of the tires (Do them all at the same time during the test so that it's all evenly balanced.) and pull forward about 50 feet again. More of the center will be rubbed off.

Let another 5PSI out and repeat as necessary. Eventually you'll wear most of that line off in one shot. Note your pressure.

The next morning when everything is cold check your pressure. This will be your new cold pressure. Now you'll have a cold pressure and a hot pressure that is custom tailored to your exact rig.

I've done this with my truck and both trailers, it works well to maximize tread life while being safe. You aren't going to stray much below the tires max rating, least you shouldn't.

[elliott-maine]

110 is fine.

[NALSO]

Thanks for the replies.

62 mph is a good safe speed, if you need to pass, pull into the left lane, do what you have to do and merge back over to the curb lane.
Don't forget to thank the driver for letting you back in, that's my motto!

Safe travels,

Why would anyone go 70 to 75 with a camper? just because you can? I hope you never have to stop quickly going that speed.

I don't think anyone should ever go faster than 65 with a camper or a Class A etc..

My top speed is 62 when on an interstate with a posted speed limit of 70.

Slow down people and smell the roses. It isn't a race to get from point A to point B.

Always tow no faster than the tires are rated (in our case that's 65MPH)

We usually enjoy the secenery and set the cruise control at 63MPH

Suggest you invest in a TPTMS (Tire Pressure and temperature monitoring system) to keep a eye on proper inflation and the tire temperatures while towing.

Until then, before every trip, check your tire pressure with a quality digital tire pressure gauge (@ $10 on Amazon). Check your TV too!

Most tire failure is due to under pressure and overheating (too hot and your tread will seperate)

If this is a new 5er, sooner rather than later you will want to replace the "Stock" tires with a higher quality tire with metal valve stems. (Maxxis or Goodyear seem to be the best around).

[mahdi]

PTMS is a great idea. I recommend it on long trips.
