Ply ratings of tires

why are you mentioning 12Ply?

My RV tires now are 12 ply not 8 ply and I got a good deal on these brand new 10 ply tires if I want them. I just wanted to see if anyone that is driving a 30 foot motorhome with the P30 chassis has 10 ply tires on their rig?

sorry I thought you said you had 8 ply tires but I see now was that was the size 8R I mistook that as 8 ply my bad
and u never indicated u had 12 ply in your first post so I assumed you had 8 ply

as to your question Look at the required load rating for your motorhome if the 10ply tires have a load rating that meets that standard there is no reason they wont work + will ride smoother

Well, for a little motor home that is not too heavy 12 ply should be ok. I use Toyo 16 ply rated and I feel comfortable without worrying about a blow out. My coach weighs 30K lbs.

I have a 1994 Fleetwood 30 foot P30 motorhome. It has 8r 19.5 tires on it and I need to replace them. I found a great buy on some 225 70R 19.5 tires but they are 10 ply tires? Has anyone ran any 10 ply tires on a P30 chassis?

Our MPG improved and torque converter stayed locked up most of the time unlike with our 8R. Ride improved too.

My 30 foot P30 has a GVWR of only 14,000 pounds. I would love to have these 10 ply tires on it. I think the 10 ply tires would ride a lot better than the old heavy 12 ply tires on there now. I will not be able to see the new tires until I buy them as this is not a tire store. He mainly deals in electronics and specialty Items for old restored cars. I am sure he can get 12 ply tires for a little more money. I think they said these tires are made by Bridgestone. Its a great deal for $130 each.

By the way, for you folks that are so worried about china made tires, I bought my old 8r 19.5 china made tires 9 years ago. They have over 22,000 miles on them and still look new. A lot of the miles were made on secondary roads and dirt roads. I have never had any issues with them. They were $140 each installed. I bet I could get another 2-3 years out of them easy. They do not have any air cracks at all. I do keep watch on my tires and air pressures since I have my own shop. I also carry an air compressor and check my tires daily when traveling.

I may still make some telephone calls to the tire dealers before I give on on getting the new smooth riding 10 ply tires for my light weight RV.
