tires and ride

I have noticed that wheels are getting bigger on new cars with 20 inch not uncommon. I did some research and the general consensus is the larger wheels actually impact ride to the negative however the new thinner tires help to make up for it. That has lead me to the question about tires. Are there certain brands of RV tires that have a better ride? I have 19.5 on a 2012 Winnebago Vista 30T is that is important. I run at 80 lbs per weight-could run lower on the front.

    But you do get a choice which determines which type tires you end up with. Buu the bottom of the line model and get 15" inch ordinary tires and rims, or buy the top of the line model, the SES or something along that line, and get the 19" low profile tires that ride like a lumber wagon. My last two new cars were the base models. Those 15" ordinary tires are much cheaper and last longer than the 19" low profile.

  • They ride like log trucks on even small bumpiness etc.
    Tires on our little black car are only 18 inch but with the suspension it is a firm ride. The bigger wheel weigh more. Some car's I've seen they had to lower the suspension and do wheel well work. They just about had to change rear differential gears too. It cost them mileage.
    Those little rubber band tires run pretty high pressures for a car.
    The twenties on the Edge are 45 lb. The 18's on the black car are at 38-40 with performance tires.
    I saw a 70's Chevy the other day with rims that appeared to be in the neighborhood of thirty inches. They were certainly larger diameter than the MH or a Semi by a good bit. They would have to jump down from the car or maybe they had a rope ladder.

  • Thinner tires sure don't improve the ride any. Wider sidewalls soak up some of the impact whereas thinner tires have to have stiffer sidewalls to do the same work.
  • Are you saying you don't like the ride of your tires? Lots of brands to choose from out there. As long as the tire is inflated properly and can carry the weight, you should be fine. Your manufacturer spec out your MH to ride on 19" tires, factoring in the weight/carrying capacity of the MH. Suspension is another factor in ride quality.:h
