Georgetown Tire Pressure

[cjmorse]

I have a 2015 Georgetown 360 XL. The plaque on the wall says 100 lbs cold tire pressure. The tires say 110 lbs cold tire pressure. The coach rides pretty rough at 100 lbs. Would I be making a mistake to reduce the pressure to 90 lbs.

Tires can be fit to a variety of vehicles....not just your motorhome, so you may see pressures higher on the tire sidewall than what's listed for your Georgetown.

Forest River is suggesting 100lbs given the maximum load you might carry in your rig. I'm assuming you have 22.5" tires?

If you run softer than recommended, you need to keep careful watch that you don't load your rig heavy just for a softer ride.

Thanks. Think I'll stay at 100.

I keep all of my tires at 100psi cold and it could reach up to between 118 and 120 which is in line with the 20% in theory when it hot.

The RV would run a little rough on some roads, but I think that it would be safer for me as far as load concerned. But that is for me and for now. I may change my mind later to soften the pressure a little as I feel more comfortable with my RV, the load, and the road.

That said, I do not think that you have to lock yourself in with the load posted on your RV wall. My RV came with the Michelin tires, and I can use the load chart from Michelin to determine the minimum pressure for my tire to match my load. Of course, you have to take your RV and weight it at your local truck scale with your expected load which including all passengers, fluids, etc. The scale will report to you all of the weight on the front and the rear axles, you may also weight your RV on each tire as needed. Once you have the load, you could balance your RV loading scheme and use the tire pressure chart to pressure your tires accordingly. This would be your best bet if you would like to deviate from the recommended pressure chart on your RV wall.

Here is the link that I would use from Michelin should I decide to deviate. If you have another brand of tire, you may do some research to find something similar.

Good luck.

We loaded the Rig, took it to the truck scales, weighed each axle, reviewed the Michelin web site and cold we keep ours at 90.

90 for me too.

FWIW I Recently added A TPMS system.
Tires are set at 80 lbs. Within 50 miles they are showing 90+.

I weighed mine and dropped pressure to 85... Huge difference in driving and handling- drives straighter and rides better.

My 360 handles great at 90

I find running with a 1/2 tank of water shore helps the handling if you have tried it maybe you should.

I'm with Tamdie as well as Ken and Terry. A lot depends on what weight the tires have to support. I'd suggest you get unit weighed ( if possible all 4 corners )with what you normally travel with ( people, cargo etc), adjust as much as possible for any imbalances and then consult Michelin Tire chart for correct tire pressure based on weights tires have to carry.

How, in God's name, do check the outboard tire pressures on the rear?? Our inflation stems are pointing toward the space between the tires... !!!

[Walter Pigeon]

How do you check the tire pressure on the rear tires? The stem on the outboard tires point inward...

[cfo111]

you use a duel foot air gauge it's made to do that very easy to do.

Thanx, I'll try that...
