D E or G tires

I have some 4 year old Towmax China bombs and had a few blow out on a older 5 wheel and looking for some tires that I won't half to worry about. The towmax I have now are rated D. To be safer should I go to a E or a G. I heard that the G rated will ride rougher.

Depending on weight of your 5th wheel "E" is the min. "G" is my choice but stay away from Towmax, throw them away. There are a number of good tires but my choice is the Goodyear "G" rated tires. Since switching to Goodyear G rated tires years ago, I have not had 1 flat tire.:)

Depending of course on the weight of your fifth wheel, I'd definitely go with the G rated tires. Sailun makes a great tire.

Just put sailun on my trailer made a world of difference. I think it rides smoother and with less bounce

Before you buy your tires you need to find out what your rims are rated for. If you currently have "D" and you go up to "E" you would have more than enough tire. I would not expect your rims to be rated for the PSI associated with a "G" tire.

^^ agree ! ! Check those wheels, pull of one and look on the inside of it for a weight stamp.. I would be very surprised if an OLDER trailer that came with "D" tires had wheels that could handle a "G" inflation..

Had G rated, installed on my fifthwheel. No difference in ride/towing. 15"...

Good point. You probably don't need more tire but just a better quality tire such as the Provider ST tire. As others more informed say it depends.....on your trailers gvwr/OEM tire size/wheel psi and load ratings/the trailers axle ratings.
Carlisle improved their ties with the RH series and now a new HD series that seems to be a huge improvement.
Goodyear Endurance ST replaces the problematic Marathons. Above tires are the new gen ST tires with 75-81 mph speed ratings.

I see you may have a 26.5 Jayco Eagle. These units have just under 10k gvwr. Most D tires now days for a 10k trailer are the ST225/75-15 D at 2540 lb per tire. The only benefit of a 15" E comes at 2830 lb 80 psi and if your wheels are rated for that much psi. If their a 6 lug wheel then they should carry a 80 psi rating at 2830 lb capacity.

And for sure that trailer doesn't need a 16" Sailun load G tire at 4080-4400 lb/110 psi. In the world of trailers unlike a truck over a 20 percent reserve capacity above your trailers axle rating isn't better.

If your trailer has 16" wheels then the best tire on the market for a 10k trailer would be the LT225/75-16 E at 2680 lb capacity Or the LT235/85-16 E at 3042 lbs (if there is enough room in the wheel wells) in a Bridgestone R-250 all steel commercial class tire. You can expect 40k-60k miles and 6-8 years of trouble free service with good tire maintenance.

Sailun tires-
Who sells Sailun tires in California?

I too doubt you have 110psi wheels so you can't get Sailuns, anyway. I see the new GY Endurance has an E-rated tire in 14". I don't know anything about them and it's too early to know if they'll do well.

Check out the Sailun website for their dealer locator.

Also, Les Schwab in my area stocks them, if you have one close by.
