I find it quite amazing the ole tire debate still rages on in earnest across every RV forum. Why is that? Rhetorical question but wow no clear cut answers. One just has to do a lot of research as every individual will vary. Here is an old post that I found quite interesting…
U.S. Federal Testing Standards for ST and LT TiresTrivial knowledge for some of you, but some good info with verifiable sources. This was just another bullet point that gave me more confidence in deciding to replace my ST tires with LT giving much higher load capacity reserves along with higher speed rating. My 2 cents is any RV over 10K lbs should seriously consider using LT tires. Also, my factory documentation that came with my fiver specifically states ST or LT tires be used. It also states that the outside placard showing tire info is the
minimum required. Granted no tire will prevent blow-outs but after a ridiculous amount of reading I feel I’ve made the right decision, can now rest easy and that’s all that matters to me.
