LT or Comercial Traction Tire on Repu

I've been using my REPU pretty heavily (no pun intended) and I know on several occasions I've surpassed the load rating on the passenger rated tires I currently have on my truck. Under load, it handles pretty poorly and I worry about blowouts here in toasty texas. I've been looking to see if they make a Light Truck or Commercial tire with a load rating of C or more that will fit the stock rims on our trucks.

There's a thread on the suspension forum that mentions the stock tire size that came on our trucks works out to a 185-80-14. Turns out this size is used on several types of delivery vans and the Vdub microbuses. The size is listed as 185R14C, and they're available in a "C" or "D" load rating. At a full 65PSI, most brands are rated at 1875 pound load per tire.

Is anyone on here running this type of tire?

The VW guys seem to swear by the Hankook RA08. Supposed to be great all around. Good grip in dry wet snow and mud, long wear, stiff sidewalls, quiet etc. It's available in 185R14C and 195r14C.

It's on sale here for 79 a tire...

Tire

I'm running Yokohama Geolandar H/T-S on the rear.
LT215/75/15 100 97Q Load rating is "C" (PN 05105)

Max load is 1765lbs at 50 psi (per tire ???)

They ride unbelievably smooth, much better than I expected.

Can't remember what I paid for them.

Bruce, we had those tires on our SUV and were also very happy with them.

If I change over to 15" rims, there would be many more options. The challenge is finding a LT tire in 14"...

Well, I've had the tires on for a month or so now, and I have to say, I love them!I've been running mine at 45 PSI with the truck unloaded, (though if you want a softer ride, they do fine at 32) and I have to say, it's one of the best things I've ever done for my truck. With the stiff sidewalls and the grippy tire compound, the truck rides and handles better than it ever has. It's a great highway tire, It rides dead smooth at 65, and it continues to ride well all the way to 90, which is as fast as I ever drive in my truck.

Since I've had them on. I've noticed almost a 1mpg increase in mileage. The manual steering seems easier as well. My guess is this is due to the low rolling resistance and high PSI, though it's interesting that the tire size the truck came with seems to work better than what I was running.

Loaded, the truck feels MUCH safer. With the old tires, she was quite squirrely in the turns. Not so now. I've had them as high as 60PSI loaded on the rears, and it's a great change.

Now, I would not run this tire if you use your truck like a sports car. Up to say 5/10ths, these tires are fine. More than that, I think you'd want a sportier tire. But that's not to say they don't handle well, cause they definitely do. We have these routes known as "Farm Roads" here in TX, and they are generally macadam (tar and gravel) with long straightaways with some sharp turns here and there, and have a speed limit of 65. I can run them pretty well, but once the truck starts to drift a little in high speed turns, they do not do so well.

YMMV :-)


Here's a writeup from Tirerack that describes load ranges, the difference between Passenger and Light Truck (LT) tires, etc.

Nice. Yes higher tire pressures requires less effort on steering as the tire is ballooned in the center of the tread. Since theres a smaller contact patch with the road fuel mileage goes up too. Of course, it wears the center tread faster and will eventually cause the tire to prematurely wear so the cost savings of high inflation pressures is questionable at best.

Glad u found a tire that works, looks like a winner.

Tire wear also depends on how you drive your truck... If you tend to corner hard, you'll wear out the edges faster, so a little higher pressure will tend to make your tire wear more evenly.

Best way to tell is to go for a drive and measure the temp accross the tread. If it's nearly the same, you're running the correct pressure for your driving style and load.
