Need tires - Advice

[john1345]

To load balance they should be the same. I never seen one that had different size tires from front and rear.

All the large Newmars have different tires. Look at a mountain air or Essex
Most all the Tag axel will also.
Like I said the Berkshire are the same and most all Gasser are.

We are talking same size on the Berkshire which I understand. But TA quoted a different steer tire. It was about $30 more than the rears.

I know my 2011 RB is all the same. Their are lots of different Berkshires nowadays so maybe they changed something.

[Phil57]

What's on yours now?

[TaterColo]

Michelin XRV all the same size - although I found the DOT date on the steer tires but not on the drive tires. Not sure if that means anything.

I have been reading about people upgrading from the 255/80 to the 275/70. I have tried to contact FR and all I get is to contact a local tire dealer to see what works best. I would like to upgrade to the 275's so I don't have to run higher pressures for the weight. Right now for max weight of 29,410 lbs I have to run 110psi with the 255's. I have done the research and if I switch to 275's I can safely run 90 -95 psi. Do you have to change anything else, ie air bags? thanks for any advice. My coach is a 2008 Berkshire 360QS with the Mercedes power plant.

Contact a Freightliner Oasis dealer and they should be able to tell you when mine was done they did the front axel air bags and re rated the front axle to 12000 lbs.

Hello fellow campers.

In two separate trips I have blown 2 tires (current Good Year) with less than 7k miles and inflated to 74lbs. Between the two it caused over $6k in damage to my 2013 Sanibel RV. I am looking at the Michelin replacing all 4 and my spare tire too. Make some noise and let me know what you all think.

Current RV Tire information
ST235/80R16 GoodYear Marathon
Load Range - E
Max Single 1550
Max double 1360
Cold 80 PSI


Looking at these
Michelin LTX M/S2
LT265/75R16
Load Range - E
Max Single 3415
Max double 3085
Cold 80 PSI

dreamin533: I also have a 08 360QS and last year I noticed sidewall cracking on the tires. I knew that I had another 4,000 miles to go for the year, and didn't want tire troubles on the road. I found a local Michelin truck tire dealer and went to get tires. I found that the 255/80 XRV could be ordered- if I wanted to wait at least 6 months. It was explained that Michelin makes a certain number of tires of a certain size and type, then retools for the next tire. The 255/80 XRVs had already been sold to new RV production, no replacements were available. The dealer rep looked for a replacement, and told me a 275/70 XZA2 has a .2 inch difference in circumference and would cause no speedometer difference. They are also capable of a higher load, at higher pressures. According to the Michelin comparison charts, they have less rolling resistance than the same size XRV. I had them installed, and am happy with them, although with the extra width seems to have caused a slight (.5) mpg loss. The speedometer still matches the GPS, and ride seems a little less harsh than the original tires. I hope you also can find a satisfactory replacement.

I had a tire blow on my first camper. Changing that on the side of the road was a miserable experience. I'll pay for good tires from now on. Search this site for 'china bombs' and read the posts. You will see a lot of people mention 'Maxxis 8008'. Google that and read. No brainer in my book. Replaced what came on my second trailer with these after 4,000 miles.

Last Nov (14) two tire dealers told me not to drive on my existing tires - two were badly cracked and the other two had stretch marks. Date on the tires - Dec 13. Not even a year old. They were the tires that came with my new Rockwood 8282WS. Make was Open Range. Got authorization from Rockwood to replace tires to a value of $75 each as that is what they would pay an authorized dealer for tires. Needless to say, I upgraded the tires from 6 ply to 10 ply and slightly larger. On the tire dealer's (Discount) recommendation, I purchased Hercules tires, 3 year, 36,000 mile warranty. They cost $102 each installed and balanced. I have since put on 3,000 on them and they still look like the day I purchased them.

You do know this is the Berkshire forum not Rockwood. I need to get 6 tires all have cracks in the sidewall 2010 manufacture date. Any deals going on?

I haven't had to replace my tires yet. When I do I will shop the FMCA Michelin discount as I here that's the best deal.

What's the FMCA program?

[Phil57]

Family Motor Coach Association. It's a club like Good Sam's but only for motor homes.

[Phil57]

If you own a motor home I highly suggest joining. They have many benefits that come in handy. A nice magazine and excellent rally's.
