they appear to be rated R, which is 106 mph rating for light truck/offroad tires.
I have a set of 4 35/12.5/15's for sale if anyone needs some. Two are only a week old, great for the front, and the other two are at about 65%-70% tread depth. Had them on last week, no vibrations detected from 0-85 mph (my car would not go faster than that).
I sold that car and the new owner wanted to go down to 32's.
I have had them in 285/75-16 on my '95 G320 for almost two years. In that truck the engine spinning 4000-4500 rpm still over powers the tire noise. Can't say I've had them over 100mph much but I have run them 85-90 for a few hours and not noticed any problems. If you keep the pressure up, as you should at speed, they are not bad. The growl pretty good at 25psi or less.
Harald, sounds like you need to upgrade that stereo With six speakers, an 8" sub and 500 total RMS watts I can hear mine just fine at 100 mph[)]
I have had one blow out on the way back from the Anza G event, most likely I thought, sidewall damage on the trail, especially because of which tire it was! the right rear.
.....but it ended up having overheated. This was at about 65 mph. We were able to manage getting to the shoulder for a swap thankfully becuase this was on the LA expressway, which basically = death if you stop in the middle!
On the Rubicon Trail, Another set I had lost all the treads off the outer row becuase of fender rubbing in the rear.
stiffer springs changed that, but at a loss for some articulation in the rear perhaps.
