changing to17.5 tires
I have a 2006 3400rl with dexter 6000lb. axles. I was wondering if anyone with the 6000 lb. axles have changed to the 17.5 tires. Will the current hubs and studs be sufficient or will the studs need to be longer for the alcoa rims, I have the original steel rims. I was looking to to upgrade for more peace of mind. Only other option is stay with the 16 rims and go with the goodyear g614 tires.

If you haven't priced Alcoa wheels, you might want to make sure you're sitting down when you do. I'd do the Goodyears.

hubbub52, I bought a set of Alcoa Aluminum wheels 16" but I had a Cambridge 358 (It was Heavy) 7,000 axles Dexter never lube and the Goodyear G614's. I have owned 3 5th wheels with the G614's and never had a issue. Make sure the rims will handle the air presssure if you use the G614's (110 lbs). If you go to the 17.5's the pressure is 125 lbs cold. I used South West Wheel in Dallas Tx. They can give you good advice. We have the Goodyear G114's 17.5" have less that 5,000 miles so for but they are doing great, and run cool. Good Luck with Your choice. GBY....

hubbub52, I also have a '06 3400 and will be upgrading my tires this winter to the Goodyear G614s. I stopped at Tredit Tire and Wheel in Elkhart, IN, a couple of weeks ago. These are the folks that import the TR6, 8 lug wheels. They said all TR6 wheels are rated for 3500 lbs each and 110 psi. They gave me a letter to this affect and also stickers to be placed on the inside of the wheels. I was going to go the Alcoa route because of the pressure thing, but now will just buy the Goodyears. Hope this helps!!!!!

hubbub52, i also havd steel rims, and after wearing out an old tire and shreading one, i replaced all the tires with the Goodyear G614 for peace of mind and better load capacity. The G614 has a heavier side wall constructon and if you want to "feel" a differance, try lifting your old dismounted tire and one of the G614s before they mount it. As the tire dealer said, its a heavier built tire and thats why its marked "Regroveable" on the side.

Please do not air up your tires to the maximum pressure if you are using the G614 RST tires. That pressure is way too high for the load they are carrying, and you will not get the best wear characteristics or the smoothest ride. You may also have trouble finding a compressor that will provide that pressure, and you haven't seen anything until you've seen a tire at that pressure burst.
Here's what Goodyear says about tire pressure. "Since RVs can be loaded with many different configurations, the load on each tire will vary. For this reason, air pressure should be checked based on the load on each individual tire. Inflation pressure should be adjusted to handle the maximum tire load, and all tires on the axle should carry the same inflation pressure."
Get the actual loads on each tire and check out Goodyear load inflation table
