Fifth wheel tire replacement

Hi everyone,

I know this topic has been discussed much on this forum, but here we go.

I have a new (for me) fifth wheel TH, and after my first 2500 mile trip I see a bulge in the sidewall of one of my tires. Needless to say, it's replacement time.

The question is, since my TH is a tandem axle (7000# axles) and is rated for 16,500 GVW, and I have all e rated tires now (235/80-16), can I go to g rated tires such as the Sailuns? (I believe my wheels are rated for 110# of pressure) If I can, and decide to do this, can I do one axle at a time? Is this advised? Anyone know of a good place to purchase. (I'm in southern Calif. At the moment)

Also, I'm considering bumping to 235/85-16 tire size. Same questions?

Any insight and especially any direct experience with this situation will be greatly appreciated.

Miker ??????

    I don't think I would do one axle at a time. Seems like the handling differences of the tires may be detrimental to them. I would probably go to the 235/80-16 "G" rated Sailun, just because a little shorter can't hurt. :) Four of those will give you about 16,000 lbs. carrying capacity, which should put you several thousand over your actual weight on the axles.

    I bought mine through SimpleTire.com.

    Your tirel logic is right on the $$. The biggest size tire and highest rated tire that your rims can handle?? More is better! I buy new ties every 5 years??
