Tire recommendations November 07, 2023, 11:50:00 am Good morning!Glad to be alive today after not one but TWO blowouts on the road yesterday! The first blowout, we used the spare. Then not even 20 miles down the road, the second one blew out!Thank the good Lord for keeping us safe on a very busy interstate with folks whizzing along at 75 mpg!Had to buy something to limp back home and ended up with Hancook DynaPro HT. Never heard of them and they seem kind of hinky to me. But when we are stuck by the road, you get what you get. Looking to buy ALL new tires and ask your collective wisdom on what brand. Also what tire pressure are you all using? Maybe we were using too low a pressure.'Many thanks in advance!Corky 1 Likes
Re: Tire recommendations Reply #1 – November 07, 2023, 12:46:14 pm Hi Corky; How old were your tires, brand and what pressure were you running? What position on the rig? (I'm keeping track as sort of a data gathering project). Do you have a TPMS? You have an E450 and how much weight are you loaded at? The Hankook tires come with the new Ford E450 chassis (IIRC). I prefer the Michelin Agilis CrossClimate, LT225 x 75R 16E. I run 72 psi in the front, 78 psi in the back. I'm loaded at full weight, 11,500# for an E350 chassis. These tires are good up to 90 psi working (cold) pressure. I have a TST 507 TPMS with flow through sensors, except the spare which is just a cap sensor. The spare also tells me the outside temperature pretty well. RonB
Re: Tire recommendations Reply #2 – November 07, 2023, 12:56:19 pm What a rough trip. Sorry, you had to go through all of that.Blowouts are scary and to be avoided if possible. Replacing tires when they are five to six years old and maintaining the proper tire pressure can help prevent this problem in the future.I run Michelin Agilis Crossclimate tires, other makes of tires should also work well made by Goodyear, Bridgestone, and other well-known brand names. I usually buy tires at America's/Discount Tires. The prices are fair, they have stores all over the country and good customer service.Running too low a tire pressure is a good way to experience a blowout. Fully load your LD with supplies, water, and fuel, and then have it weighed. CAT weight stations are located in most large truck stops. The CAT printout will show axle weights, Using these numbers, find the proper front and rear tire pressures in your LD Owner's Manual. The pressures shown in the Manual are the same for all brands of tires with the same size and weight rating of LT225/75R16-Load Range E. All LDs have run this size tire for decades.Larry
Re: Tire recommendations Reply #3 – November 07, 2023, 02:07:04 pm I used the CAT scale in Saugus, CA and the tire inflation table to set front at 65 psi and rear at 80 psi. I did not interpolate between the 5 psi points on thr table, just rounded up.Yesterday, TPMS alarmed for low pressure so we stopped into a shop who took the tire off and used water to find the tire valve leaking where the tube meets the grommet plate. Managed to find a serviceable substitute long valve stem at NAPA, with some extenders to make it reach. A real win for the value of a TPMS. I will replace that stem with a longer one when I replace the tires this winter (6 years old now). 5 Likes
Re: Tire recommendations Reply #4 – November 08, 2023, 08:52:57 am Corky,Hankook, Asian import, but nearly ALL tires are imports. Seen it a lot through America's Tire and their Subsidiary Discount Tire.I run BF Goodrich Commercial tires on E350 Chassis '88MB. GVW is 11,500 pounds so. I run Front 70 to 75 and Rears 60 to 65. I started with the data plate pressures F 65 R 55 and added 5 PSI. I look at the tread depth wear and surface contact pattern to adjust the Pressures. Two extra adult Children require extra 5 psi in the rear tires.The front anti sway bars typically require an increase in front tires pressure with my tire pressure method. My actual wheel loading, you don't want to know. I use Range E tires instead of the specified Range D tires.
Re: Tire recommendations Reply #5 – November 08, 2023, 02:27:56 pm Many thanks to all who wrote in to help! We just ordered the Michelin Agilis Cross-climate tires at the local Ford dealership. They can do all the work in one place-install, balance, and alignment; so we decided to go with them for convenience sake. While they are at it, they will check all the other stuff-like brakes etc-which probably needs checking too. Whew! What a scary experience that was! Especially since it was two blowouts on the same day! I was beginning to think that all the tires would be flat before we got home! Not sure what to do with these two Hancook tires that we had to buy to get home. May keep one as the spare, and on a really long trip, strap the second one onto the ladder! Haha! If someone is interested in buying them-let me know. They have about 20 miles on them!Many thanks!Corky
Re: Tire recommendations Reply #6 – November 08, 2023, 02:34:15 pm On a side note, we had 70 psi on each tire per the manual based on our prior weight. We will load up and get it weighed again to see if there has been a change. The second tire guy who came out on our second blowout said we should run all the tires at 75 psi all the time. So, there is that to consider too. And the tires were due to be replaced. The tires only had about 30K on them, but they were older too and they can go bad just sitting there. We had planned to replace them in the spring of 2024, but the tires had other plans Corky
Re: Tire recommendations Reply #7 – November 08, 2023, 05:12:21 pm Corky, I was sorry to read about your tire failures. But the question I have, and I think someone else may have asked, was were the tires that failed the original tires that came on your Lazy Daze?If those tires were the original tires, at over 10 years of age, they were well past their safe lifespan. There may be a lesson forfolks who base tire replacement on how much wear is on the tire instead of wear AND age.If I were you, I would keep one of the new tires as a spare. I would think your current spare tire was probably aged out too.Good luck with your new tires. I hope you have some good tire stems on your new tires.Steve K 1 Likes
