Tires again, but not the same question...

[rldriver]

It’s time to replace the "Freestar made in China" with new tires for our 2007 340RLQ Big Sky so I went back and looked at the recent posting on tires and it looks like I (and others) may have a problem. I ran the RV across the scales the other day and found the weight on the axles to be 12,700 pounds. I also checked the side to side weight and to my dismay found the right side to be 6000 pounds and the left to be 6700 pounds or 3350 pounds per tire on the left.

Looking back on a post from LonnieB I find the Hankook load range G to have a rating of 3330# @ 105psi and the Goodyear LT235/85 R16 RST G614 to be 3750# @ 110psi. So that leaves me with only the Goodyear to pick from as I am over capacity by 20 + any fluids that I have in the tanks on the Hankook.

My aluminum wheels are rated at 3750# @ 110psi, looks like I am close to max on every thing.

Now my questions are:
1. Are there any other “good” tires out there that have a load range of over 3330#? I spend most of my time on the West coast.
2. The tires that have failed are ST235/80R16. Am I going to have any problem going to a LT235/85R16? 80R vs 85R

Thanks in advance for any assistance.

I just came in from looking at my neighbors G-614s and they are rated for 3750 at 110. Not sure where ya found the #s you posted but that is the load range posted on the Goodyear site also. My Goodyear Marathons are rated for 3420@80lbs of air. There are a lot of good tires in that load range. On most there two load range listed, single and dual. The dual rating is usually less than the singles... Dave

Dave, I went back and made the correction from 1,750 to 3,750#. I guess I hit the wrong key. Thanks for the help.

Dick,

Unless I am mistaken, the rise from floor to center of the axle between 80 and 85 is 1/4". So there is no negative effect from using the 85. I put the 85s on my rig when I changed from the Missions to the G614s.

Hello Rldriver,

Two other brands come to mind,the first is a Solid Trac Radial A/S LT235/85R16 load range "G" (STR18) by TBC Corp.Memphis Tenn (dist)This tire will reguire a high psi rated wheel-(110psi) and a 6.5" wheel width per Solid Trac chart.The other is a Power King in load range "G",not sure of all the sizes but a 7.50-16 is available.

I've seen the Solid Trac and was actually a little impressed,I'm considering a set & wheels for our Mountaineer if we decide to keep it.

I had a great deal of trouble with the OE tires on my rig, and switched to the G614s. The ride on our trip to the Canada Maritime provinces was head over heals better than the OE's had, and I had much more confidence. I had them balanced and filled with nitrogen, checked the pressure every time we moved, and it held the entire 3 weeks.

I think there is a real problem with putting truck tires's on Rv. As I understand it the RV tire allow the tires to move on wheels and the truck tires are to stiff to allow mvement when you making turns when backing up. IMHO

I highly recomend going to the Goodyear G614's. I have ran the G614's on the last 3 5th wheel we have owned. The Cambridge 358 by Keystone we had the G614's and for the poeple who are familiar with the Cambridge know it was very heavy. I ran over 20,000 miles with the Cambridge and never ever had a tire problem, I did have two of the Aluminum wheels crack and of course Keystone took care of the situation. We are going to have Goodyear G114 17.5" on our new 2010. We have 614's on our 5er now. If you watch there are some people upgrading to the 17.5" tires and wheels and are selling the G614's with wheels. Keep in mind the wheel require 8 lugs. Good Luck with your choice. GBY....
