245/70R19.5 12ply verus 16ply

Recommended Posts

looking for new tires for my 32 foot National Seabreeze, have 245/70R 19.5 Michelin XRV 12Ply, which they discontinued, and now offer 245/70R 19.5 XZE which is 16 ply. My question is will the 16 ply be a much rougher ride the the 12 ply?

Thanks in advance

I have no data but the higher Load Range   F > H  will probably not impact ride in a meaningful way.

An advantage of the LR-H is the ability to run higher inflation to give you a higher Reserve Load (excess capacity)  I would suggest a nice 15% based on the Load Inflation tables is possible.   You do know what your actual tire loads are don't you?

If I was buying new tires, I'd sure check around on various forums prior to buying Michelins.  There are many posts about problems with them on motor homes.

The benefit states that you may find a lower cost from a different supplier in your area. I bought Firestones for more than $100/tire lower than the benefit, but that is where I live. Bridgestone owns Firestone. Top of the line Bridgestone design are used on Firestone one or two years later. My first motor home had Firestone tires, so I was comfortable in using them. They have been running for about 9,000 miles without any problems. Go to the Advantage dealer and ask if there is a different manufacturer that has tires that are suitable replacements.

Do you have a Load & Inflation table for Michelin tires of that size?

Using your "4 corner weights" find heaviest tire on an axle. Then find the minimum inflation needed to support 115% to 125% of the heaviest end (depending on how much margin you feel you need). Then you know the inflation to set your tires too
