I'll bet AT barely looked at the old tires. They were probably focused on mounting the new ones. After all, they already had your business and since they don't do alignments ............ A 235/60R17 has a Load Index of 102. A P245/75R16 has a Load Index of 109. An LT245/75R16 LR E has a...

This is a terrible idea. The van is already under tired, and this would make it worse. Try selling the tires on eBay and get new tires at the local tire shop.

My experience with minivans goes all the way back to the invention of the minivan - and there have been tire wear problems from the beginning - mostly alignment wear. That seems to be the same situation today. Increasing the inflation pressure is a trick that shouldn't be necessary. What the...

My understanding of tire engineering says that inflation pressure is way, way more important than SL/XL. Another way to do this is to increase tire size, but this can run into rubbing problems - very bad!! So I'd recommend using 5 psi more than the placard pressure even if that exceeds the max...

Long version: Barry's Tire Tech: DOT Codes Short version: As of April 2025, plant codes - the first digits in the code - go from 2 to 3 digits long, making the usual DOT code 13 digits long. The last 4 digits are in a week/week/year/year code. So 1022 is the 10th week of 2022.

According to Tire Guides, the OE tire size was either H78-15 or L78-15. Look in the glove box to see if the vehicle tire placard is there. Back then, placards could be found in a lot of different places and the glove box is the most likely. You can't get an exact fit with modern tire sizing...

Thanks for the additional info. I still think this is a fatigue crack. I would check the other wheels - mangniflux or some other crack detecting system. Oh, and wheel failures due to the use of radial tires on wheels designed for bias ply tires? What I remember was rim flange cracks and...

Opps!! My fumble fingers. That was supposed to be 100k

Just an FYI. Most tire wear occurs in the cornering mode. Driving straight ahead is practically free. So if you drive in the city, with all those turns, you're not going to vet as many miles as someone who drives in the country. I've seen the same tire wear out in 15k that also went 1000k...

As someone who has done some failure forensics - albeit on tires - allow me to take a crack at this. First thing I notice is that the failure is at a bend in the metal, not at the junction between the rim and the spider. That suggests a fatigue related crack at a stress concentration area...

So I gotta ask. Why?

Barry's Tire Tech: 1970 TRA Pages You'll have to dig through the pages, but it's there. Try starting on page 1-07.

The US government has nothing to do with this. What's going on is a principle in law that says if there is a generally accepted way of doing things, then doing things a different way puts you at legal risk. (Obligatory I am not a lawyer) The tire industry has published guidelines on repairing...

Be careful. The entire Primacy line appears to be OE - which means each SKU is different and likely geared towards fuel.economy and therefore might not wear well.

The way this works is that they measure the tread and figure out how much tread you have left in percent and then discount your replacement tires based on that percent. If you buy more expensive tires, they'll use the dollar amount based off the old tires.

The Nissan Leaf and the Nissan Versa take different sized tires. But if someone were to take appropriately sized tires and mount the same make/model tire on them AND operate them in exactly the same way, then they should get about the same number of miles out of the tires. My guess as to why...

Florida is one of the 5 states where tires fail more often than the rest of the states. That's because of the temperature - and while Florida isn't as hot as - say - Arizona, it stays warmer longer. Putting that in engineering terms: The heat history of Florida is much more like Arizona than...

Here's a press release dated April 2, 2025: https://www.herculestire.com/news/hercules-tires-launches-50-spring-rebate-for-us-customers?_gl=1*1mnvyze*_up*MQ..*_ga*MTE4MjE3MjAxLjE3NDg5ODUxMzQ.*_ga_GPXPBMBZHS*czE3NDg5ODUxMzQkbzEkZzAkdDE3NDg5ODUxMzQkajYwJGwwJGgyMTExNDM4ODgx Towards the end it...

According to Tire Business, the Hercules brand is owned by American Tire Distributors. They may be made by Goodyear but that could change anytime ATD wanted.

If you mean the P4 Persist AS Plus, they are non-directional, symmetrical. That means there is no way to mount them incorrectly. Asymmetrical tires will have some sort in inside/outside marking. Directional tires will have sort sort of arrow indicating the direction of rotation.
