new to towing.... buying 4 tires...

I kind of read a bunch of old posts, but I am still a bit confused.

I see that I want the E rating.
I want like 100 mph continuous speed, etc.
Load like +3000 lbs..

What I am confused about is that I see some people
talking about their "stiff" sidewalls.
Does this help the ride? I guess from some side-to-side
wandering?

If so, does the E rating get you this stiffness, or is it
a specific brand and model that I want to look for
for this stable towing ride?

2.. my second question is tread aggressiveness.
The more pure road tires are what I see people recommending
I think. But I am thinking what if I get in some soft
dirt and need to pull harder? IDK...

help.. lol

    Generally speaking, a higher load rating typically means a stiffer tire "Relatively speaking". So for a given tire line, higher load ratings mean a stiffer side wall typically. But between different tire lines, you have different methods of construction. For example, the Firestone Transforce HT tires tend to have a very soft sidewall that actually helps in daily ride comfort, but they do balloon out and aren't as abrasion resistant as the heavier carcass commercial style tires. It really requires time to sit back and compare tire construction and your uses for a given tire.

    So in this regard, maybe a more mild "All-terrain" tires would be suitable to you. Something that can handle sand and shallow mud/forest roads. The tires that tend to have adverse handling characteristics are those tires you see with the large independent lugs (Like Goodyear Duratracs or BF Goodrich Krawler KX's). Many mall crawler show trucks tend to sport these tires in these parts. But if you get an all terrain tire that doesn't have large canyons/grooves between the individual tread lugs, you won't be as adversely affected. Some examples of decent all terrain tires would be like the Michelins previously suggested, or Goodyear Wrangler All-terrain adventures, or even some Bridgestone Dueler AT Revos. This is really just a guideline as I'm not brand biased. But on the all-terrain tires I've pointed out, you'll notice that they only have some large areas to help eject mud/clay/rocks, but in general all the lugs are really close to each other.

    Highway tread tires are excellent for pure highway driving as they have constant contact with the road which lends itself to a much straighter ride and less wandering by the vehicle. That's why many posters on here are big fans of Highway tread tires.

  • Hi,

    Are you talking about the tow vehicle, and what vehicle, or the trailer, as they use different tire treads.

    The towing truck might want a aggressive tread to get more traction in the snow or on sand. Yet those things are not desirable at all for a trailer tire. It will offer a bumpy ride and less stability overall.

    I found out first hand that you do not want polyester sidewalls on a class A motorhome, because when I installed them, the back end would 'wiggle' side to side while towing our small Honda CRV down a hill. I had to change back to the steel sidewall tires like the Michelin "RIB" tire.

    As for the trailer, why do you 'need' 3000 pound weight rating? If your trailer has 5,000 pound rated axles, and is only 11,000 pounds or less overall weight, then tires rated at 2,600 pounds will work great. Only if you have a larger trailer would you also need heavier tires. Of course a truck that came with 3,000 pound rated tires would get replacements with about the same rating. Some of the travel trailer weight is on the hitch, and 20% of a fifth wheel weight is on it's pin, so the tires do not normally have as much weight capacity as the trailer GVWR is.

    High speed car rated tires are a whole different tire, rated and designed totally different than a truck tire. While sidewall stiffness is desirable in a truck tire, it is not desired as much in a car tire, where the ability to absorb bumps and not transmit vibration from the road is important. Car tires also have a softer compound, where they will stick to the road better while cornering, and give more traction while speeding up and stopping. This will accelerate the treadwear on the tires, something not desirable in a truck or trailer tire. And car tires are designed to run at 1,000 RPM - 100 MPH+ while truck tires are not designed to go over about 800 RPM. At 600 RPM, a 3' tall truck tire will be going well over 75 MPH, and that is their normal design limit.

    So what kind of vehicle do you need the tires for? What is the GVWR of that truck, trailer or whatever?

    If you want grip and a strong tire check out the Michelin LTX M/S2! I replaced my Toyo's with them and have gone all winter without any extra weight in the bed, and nary spun a tire.


    But you forgot to mention this has been the driest winter since 1930. LOL

  • I assume you are asking about tow vehicle tires and not trailer tires..
    Sounds like Michelin M/S2 might be just right.
  • Aggressive tread generally equals squirlly handling. For you in PA and this is assuming your asking about tow vehicle tires I would look at a quality AS (as in All Season) tire stick with sise and load rating that is equal to what came new on your vehicle. Installing over sized tires are of no help in loading and cannbe detremental to towing.
