65 psi tires vs 50 psi

Along with this topic, how do you determine if your rims are rated for higher pressures? I have looked and can't find anything on the rims; haven't removed them to look inside the hub.

Any additional trailer bounce as a result of the increased tire pressure?

I would get the 857 and run 65 in a heartbeat

The 65 psi moves my 205 tire from load range C to load range D. Basically that means now my tires far exceed my axle rating instead rather than just slightly exceeding them axle rating.

The tires are rated C at 55 psi and rated D at 65 psi. So I can vary a few pounds on the 65 psi. and not worry about dropping below the C rating that were on the TT for the first six years.

It was a cheap upgrade.

The biggest benefit of the D tire over the C tire is those higher 65 pressures does a better job of holding the tires belts together as it side scrubs around corners....and runs cooler than the 50 psi tire.

Added benefit of the Kumho 857 over the Maxxis is your going to a commercial service tire which gets you away from a ST tire.

Higher speed ratings , and higher capacity . plenty of spare capacity

I have 15" wheels and upgraded from load range C (50 PSI) to D (65 PSI) without a problem. The tire diameters were essentially the same. Use metal valve stems.

Likely the difference between load range D and load range E. It's not the PSI that's so important. Check the load range and capacity (like 2,500 lbs or 3,500 lbs) on the sidewall.
