Ok. It’s super weird that it started out the blue. It’s almost as if the sideways on the Chinese tires are not strong and ‘give’ to much. In any case, still frightens me. I’ll look around and see what I can find. This truck doesn’t get a ton of use so I always find it hard to spend a ton of money on it to see it sit.

True, but you also want to feel safe. The tires are the only thing keeping you on the road. Try altering air pressure and getting them balanced first. If that doesn't help, maybe start socking away some cash for a tire upgrade.

I had a similar situation with my 87 IROC and Goodyear Gatorbacks. It seemed to wander down the road and body would sway even after tires were straightened out. Turned out to be the not very stiff sidewalls of the tires. They made for smoother driving but it did constantly sway & wander around in the lane. I just pumped about 10 pounds of air above the limit on the door to reduce it. Center of tires wore quicker but drive was better. Check what is a safe limit first. Some tires can go 10-15 pounds above what is listed on the door. Perhaps a short test drive first. Also try rotating. And more importanly, get that front end checked for safety’s sake. Good advice given by others here.

Poor handling usually indicates low tire pressure, or possibly a suspension issue. Mismatched tires alone should not matter, as long as they are the proper size for the vehicle and properly inflated. In your case, 35 PSI. Lower air pressure will cause sway, higher tire pressure will cause bouncing. Any wobbling at lower speeds usually indicates a broken belt in the tire treads. Vibration at higher speeds indicates the need for spin balancing. If you do not rotate your tires regularly, or your wheels are in need of alignment, you may have excessive wear on the inside-facing tread. This would also be indicated by wobbling at low speed. The only other thing is to make sure you don't have one-direction tires mounted in the wrong direction.

Sounds like cheap quality tires. Increase tire pressures to see if sidewall flex is reduced. Cheapo tires give cheapo ride.

Above 75 mph? Wow. I only do that in my Jetta!

I just drove to Las Vegas, New Mexico from Dallas and completed a return trip to the Houston area. My father is visiting from New York and was surprised to see the 75 mph speed limit along most of the trip. When passing on a truck on a two-lane highway, you're definitely going to exceed that speed to ensure you complete the pass safely. There are stretches in West Texas where the speed limit is 80 mph. I don't find the absolute speed is as much of an issue as disparities in speed, and the biggie...inattentive driving.

I feel pretty comfortable doing up to 90 or so in my EL w/ Michelin XLTs - provided that it's a well maintained highway. There are some stretches of interstate here where anything over 70 makes me uneasy.
