We've just installed our second set of XPS ribs. Our first set started to show some wear after 8 years and 110,000 miles on our 30 foot bunkhouse. They do not ride rough as some people suggest. Not a single rivet has popped on our trailer, nor has any interior cabinetry come loose. We run the tires at 65 psi. We decided to go with Ribs 8 years ago after multiple Marathon failures and a trip to Disneyland. At Disneyland we observed that they use Ribs exclusively on there parking lot trams. They also cannot tolerate a single failure, period.

Bye,

Paul

Paul-

Very interesting information that you've been running at 65 psi with your XPS Ribs. What does your Safari weigh?

I need to make a correction to my earlier post--we are running XPS Ribs, as well--we went for the sturdier sidewalls, along with Centramatics and 16" Sendels. And we did have a too stiff running problem at 78 psi on our first run with the 16's in that we are seeing some rivets loosening, but more importantly had a cabinet burst open and drawers fly around the coach. So we're looking for a balance between 80 psi keeping the sidewalls strongest for scrubbing, and a ride that doesn't punish the coach. Our 2009 28' International weighs 6980 fully loaded for the road, so a tire pressure in the low 70's looks quite safe for the load. We're next going to try 73 psi, and if the ride seems OK, leave it there and see how the tires fare.

If you go to the Michelin RV (Michelin RV Tires | View Michelin RV Tires load and inflation tables for motorhomes and recreational vehicles. | Michelin RV Tires ) site they have a load an inflation table for the XPS RIB. It looks like they are primarily talking about motorhomes, but I think the table is still useful. They say each tire should support 2335 lbs at 65 PSI. If you inflate them to the full 80 PSI they should support 2680 lbs. Even at 65 PSI you can safely support 9340 lbs over 4 tires. That is more than sufficient for my 30fb which has a gross carrying weight of about 8500 lbs. That would leave a 9% safety factor, assuming the trailer was fully loaded, which I have never loaded it nearly that heavy.

I am buying a 30ft international tomorrow and need to put tires on it before it's trek from Iowa to TX. Can I simply just take off the 15" wheels and replace with 16" with Michelin LTX MS2.? Is there a clearance issue or anything?

I just noticed that Michelin describes the XPS RIB as a "summer tire" with traction designed for "a temperate environment" and they are not recommended to be used where "temperatures are colder" or "near freezing".

During the shoulder seasons, I often go over mountain passes with freezing conditions (but no snow or ice). Seems like an emergency need for trailer braking (maybe a deer in the road), could be a cause for concern under these conditions with the XPS RIBS.

They work fine in snow or rain.With Ice you will need a guardian angel and nerves of steel unfortunately.

But that seems contrary to Michelin's specs. Have you ever tried a hard stop with your trailer brakes in low temperature conditions?

We're the RIBS showing signs of dry rot at 8 years?

We have a few sports cars with Michelin Pilot summer tires. The compound will get stiffer in cold weather, but they warm up fine once you start driving. We drive them at temperatures well below freezing, but never in ice or snow. I would not worry about the rubber compound on the RIB having trouble in the winter, but the tread design does not look like it will grip in snow as well as the LTX. That may be a concern if you need to stop on snow, but then again, maybe not. My experience with summer tires is just on sports cars.

Yes I have had them in all types of weather from 117 degrees to 10.Snow,rain and light Ice.No worries they do great.The tread design does not pick up and hold gravel like the LTX's.

High speed V rated tires are a different softer compound designed to be sticky when warn like racing tires.You are right when they are cold or old they are hard and have no traction.This is what contributed to the death of Paul Walker the actor as it was determined his Porsche Carrera Gt was riding on the original tires that were 10 years old and hard as a rock.
UPS and Fed Ex use Michelin Ribs in our area on their delivery trucks.

Our tires showed no signs of dry rot, or decay of any kind. Just some tread wear; about half the tread was gone. XPS Ribs are designed to be retreaded to extend there usable lifetime. So the rubber compounds Michelin uses are very long-lived. We are still running a set of 14 year-old XPS ribs on a utility trailer. They still hold 80 psi and look great even though they are exposed to the sun and weather. Weather damage is just not a concern.
