My main reason for asking about the foreign-made tires stems from the Bridgestone/Firestone debacle from a few years ago. To be sure, foreign tire makers are indeed required to abide by U.S. standards, but Bridgestone, a Japanese owned company, and who also owns the Firestone brand, supplied Firestone tires to the Ford Motor Company that turned out to be defective and subject to blowout. Even worse, Bridgestone seemed at least for a while to let Ford twist in the wind alone as Fords, usually Explorers, started having very bad accidents with the media screaming that Ford was building dangerous vehicles. It also bothers me greatly that this debacle destroyed a nearly 100 year business partnership started by Henry Ford and Harvey Firestone. Some will no doubt criticize me for this, but my personal bottom line is to not place my complete trust in foreign-made products unless nothing else is available.

Uhmmm, no.
As Paul Harvey would say, now it's time for the rest of the story:

Ford specified an air pressure that was too low for the load to be carried. This was an engineered attempt to soften the ride. Tires running dangerously underinflated tend to fail catastrophically.

Folks who listened to their tire guys and garage mechanics would run those tires at the more sane 32 psig instead of the 25 psig listed on the door jamb.
When the vehicle was loaded to its rated capacity, 35 psig was the minimum. The door jamb label made no distinction between loaded and empty weights.

So, your fears are misplaced. I would trust nobody when it comes to my safety. Unless you're totally clueless about tires, it should have been pretty obvious (by wear and heat) that the "recommended" tire pressure by the vehicle manufacturer was ridiculously low. And, that manufacturer was an American icon - Ford.

Minor details 1.Tires were 100% US made in Illinois. 2.The same tires were supplied to Toyota for their pickups with no rollover fatalities.
The above were in telivised testimony.


Related question. Since all tires can fail if punctured or similar. Would you consider it acceptable for a vehicle suffering a puncture to roll over? Kind of raises the question of vehicle stability.

I like this idea, but I see several different SEM gloss black paints on Amazon. Which one are you using? Would you mind posting a link?

One issue not discussed here is tread design. My thoughts are: It looks like a lot of OTR truck/trailer tires are designed for long tread life but don't have good wet road traction. Most automotive treads are better for handling and traction but may not have the best tread life on a RV. Others look good for mud/snow but may squirm and wear quickly on the highway.

Am I off base here?

RzR,
Re: the SEM Gloss Vinyl paint. This is the paint I used. $15.29 on Amazon.
SEM 15233 Gloss Black Color Coat
https://www.amazon.com/SEM-15233-Glo...y&sr=8-1-fkmr0
-------------------------------------------------
In the meantime, I found the Rustolium "Fabric and Vinyl Gloss Black" to be as good and much less money at Home Depot or Amazon.
Search Amazon for "Rust-Oleum 248918". Only $6.56 there and about the same at Home Depot.
Allow to dry well before driving to avoid cracking. Also, it seems that one heavy coat works best.

Nope you got it.


Depending on the vehicle and when/where you plan to travel a "Rib" design would be the quietest. If you look at highway Bus that is what they run all around.


For large tires (19.5 & 22.5) I don't think you need the cost, noise and worse mpg from truck "Drive tires" unless you plan on driving in winter



P/U & Class B & C can go with "Highway Traction" all around, Unless you plan on going off the road then a Traction design would be in order and there are a couple of levels with some being real heavy lug. I had goodexperience on my Class-C for 7 years on these HT tires available in 13 sizes 15" - 18"

If you go off road occasionally then THIS AT might be better in the 12 sizes. It is considered "on-off road in the advertising.
Real serious off-road traction means a design more like this

In all the miles I've driven, I don't recall a particularly large number of semis sliding off the road in wet weather. In fact, it sure seems to me those tires are shedding a bunch of water whenever they pass me. Now, that could be because there are a bunch more tires, or because there's more weight on each tire. But, you have to recognize that is pretty much the same set of variables that your motor home is operating under too.

You do realize that painting tires will probably void any warranty, just sayin.
