Rims

[Darkbloodmon]

A quick search does show that the 2010 Sprinter 2500 has 245/75R16, but not in a 12PR. The OEM tire has a 120LI rating.

I’ll ask again, can you show me a smaller tire with a “much” higher rating?

I linked the 12 ply tire for the Merc Sprinter.

Quick search for a 2010 Mercedes 2500 Sprinter Van Factory tire size. 12 ply, 123 LI, 3417lb max load, 245/75/16

The tire size is factory, but the tire specs exceed the factory requirements.

An F350 with a 50psi 96 LI tire… um, no… not even close. An F350 couldn’t run that tire empty with only 3,130/axle worth of tires.

But it did, and probably still does. Not to mention it was 4x4.

I cannot find anything indicating the OEM spec 245/75R16 is a 12PR, only a 10PR.

You linked a 12PR 245/75R16, but nothing that indicates that it was OE spec for the Sprinter 2500.

I think you need to improve your research skills.

Please show me any F350 with a 96LI tire from the factory.

I think you're miss understanding or miss interpreting what im saying. I did not claim the OEM spec for the Merc Sprinter was a 12ply, I said I could find a smaller tire than what we were referring to in this thread discussion 17" + with a higher load rating. The Merc Sprinter linked has an OEM tire size of 245/75/R16, I found a tire for it that is smaller than a 17" LT tire with a higher load index.

I didn't say the F350 DRW I physically towed came with 24.5s from the factory and 96LI tires, I said It had 24.5s and was running something with ball park specs around a 96LI tire.

I think you need to put your readers on.

Now you’re starting to make sense… you are talking tire sizes, the vehicles they are in on is immaterial to your point and just confused it.

It’s not uncommon to find tires for 16” rims that are rated higher than tires for 17” rims. 17’s really are the red headed step child of wheel sizes for HD trucks. You don’t have to find a 12PR 245/75R16 to get a higher rated tire thou, since the 10PR size has a higher LI than the equivalent tire in a 17” size. Both the 16” and 17” version are rated lower than the 18” version, all with a 10PR.

The AZ800 doesn’t come in 24.5” sizes. So were the tires mismatched to the rim, or the rims not 24.5”? The 24” versions also didn’t have a LI as low as 96, not that 112 is enough but it can at least support the 6.ohno.

Correct I'm strictly talking tire sizes. I'm referencing vehicles that would run x tires due to its weight requirements.

I'm not saying you have to find a 16" for a higher load rating, im just pointing out for the sake of this discussion that there are tires smaller than 18" with larger or comparable LI. Additionally I don't think tire squirm can be isolated to tire size, its a subjective symptom across a variety of tire manufacturers as a result of their proprietary tread compounds and mfg. process. Higher shelf tires may have little to no squirm compared to lower shelf tires, consider it a break in period.

The Hino 268 Roll backs I used to drive were notorious for tire squirm on the cheap Hercules tires they used. The wheels were 19.5 on 4 corners but the steer tires had a shorter section width and a much higher side wall, compared to the rear DRW axle that had a wider section width and short/low-profile sidewall. The tall tread blocks on new tires caused the truck to fishtail and shimmy loaded or unloaded at highway speeds from small steering movements. The break in period lasted a while.

If they AZ800s don't have 24.5s then they were 22.5s, I know those wheels on the F350 weren't 19.5s and I also know that Atturo does cater to the show truck market with large tire sizes and short rubber band sidewalls that can be hard to find. Point being he was grossly overweight (while empty)for those AZ800s that were no where near the mfg spec LI for the truck.

Yes lots of good LI options on 16’s, but there are also clearance issues with brakes on some more modern rigs.

The AZ800’s don’t come in any xx.5” sizes.

 

[BigPapa]

The worst squirm I've ever had was on a new set of Michelin LTX M/S tires. Lasted @ 4K miles.

Again, this form really needs the ability to laugh at a post.

If you can’t see the benefits of 18’s over 17’s then it’s just time to stop posting, since your line of thinking has become antique.

You're making the point that 18's are better than 17's by load index alone, I'm making the point that tire size is irrelevant of load index and tire size becomes subjective preference in terms of ride quality.

 

[AH64ID]

At least put some effort into your examples.

Tire size is not really irrelevant to load index. Lots of factors affect ride quality and handling.

LI is a major example of why 18’s are better than 17’s as a general rule, but it’s not the only thing.

I’ve ran 17’s, 18’s, 19.5’s, and 20’s all at or near max rating.

The 19.5’s obviously do the best, but also have the most drawbacks. The 17’s handled the worst at max load. The 20’s do slightly better than the 18’s but have more drawbacks for rougher roads so the 18’s are the best all around size for winter, heavy, and rough roads. Plus 20’s are $$$, but I do like them as my main tire aside from during hunting season when I run 18’s.

I tried those for 500 miles in high hopes for a stable tire. I had the 75 series. My wife refused to ride with me they had so much squirm. I built up the miles and tried all psi's. No dice. great looking tread and they balanced easily. Discount exchanged them for Toyo AT2's 285-75-17's which still didn't have a completely stable ride with my former 2200# popup. I should have just gone with 18's.

Did you put them on the stock rims? If so. that might have been your problem with tire squirm. I installed them on another set of rims, Mickey Thompson rims that were sized for the Nitto Dural Grappler tires. The rims are now out of production so, another rim would be needed.

I also pull a little heavier trailer than your pop-up a Cedar Creek 5er. I run the rear tires at 70PSI when pulling based on scale weights when I am not pulling the trailer the tires are air down to 45PSI.

Which had the least squirm?

 

[BigPapa]

Bridgestone R500HD’s.

Bridgestone R500HD’s.

I run those on several trailers and they are an awesome tire for their design.

The 285/75R17 is spec’d for an 8” rim, which is the stock aluminum rim width.

Tire squirm is generally related to the tread blocks, which rim width doesn’t have much effect on.

What size tire did you run on your trailer? I'm assuming a 16" rim? How did they perform off road?

I have 225/75R16 on my 5th wheel and 235/85R16 on the horse trailer. Lots of back roads miles, snow/ice, and highway miles on both trailers. I’m very happy with the tires. The ones on 5th wheel are in their last season and will get replaced for age in the spring. I’m 95% sure I’ll go back to the R500HD’s.
