F-rated 17" tires

[STEVEBROOKS]

I'm closing in on having to replace the E-rated Cooper ATR tires on my truck (which have done well, BTW). Thought I'd see what brand F-rated/17" tires anybody's used before, and what good/bad experiences they've had with them. For those that have used those tires, can they be run on the stock rims and stock ride height? Thanks in advance for the comments.

never heard of f rated 17"

i believe you'll have to go to 19. 5" for an f or higher

My 19. 5 Michelin LTX-MS 245/70R-19. 5" is "F" Rated and 12 ply. it is rated at 4080# @ 95 psi.

some e rated tires have higher capacities than others my 285 70 17s are 3750 a tire and the 265 stock size dura grapplers are even higher. I've been very happy with mine and have pushed them to thier limits and they hold up great

I have never heard of F rated 17" tires either. I don't think they exist unless you can find a set of ST tires made in China. I definitely would not buy one.

It is my understanding that ST tires,, because they are designated for "special trailer" applications are, by definition, not intended for transportation of people therefore are not subject to the same weight rating system as passenger car or light truck tires in the USA. This apparently allows ChiComm and other third world tire manufacturers to rate their tires at whatever they want to claim. Buyer beware.

All tires of the same size and same load range, for example, LT235/85 R16 LRE, a commonly used tire on Gen II Dodge duallies, heavy fifth wheels, and many gooseneck flatbed or other heavy cargo carrying trailers, are rated at a maximum weight of 3,042 lbs. at 80 psi inflation. Ditto with other tires of the same size and load range. It makes no difference whether the tire is made by Michelin, BF Goodrich, Bridgestone, or WillPop. The capacity is apparently established by some US tire industry standard and does not vary among manufacturers.

In other words, if you find another brand of tire of the same size as your OEM Dodge tire that claims it has a higher weight rating, beware of the salesman who tells you this.

Maybe for trailer tires there is a set standard but I had d load range tires that had higher payload cap than some e load range. with so many sizes available the actual payload will be diffrent. i run the 285 70 17 that have a 3750 payload, if i go up to the 285 75 it goes up to 3950, yet thier 265 70 is 3195 and all are e load range

If there are "F" 17's, you'd still have to consider that the rim might become the weak link. Because of the higher pressures for "F" tires (maybe 100psi?), the rims may not be rated at that pressure or load rating. When I had my 97, I put new 16" rims on without looking at the load rating, which was quite a bit less than the stock rims. While I never weighed too much, if you're looking for "F"s, I am guessing you have BIG plans in mind. :-laf

Like AMick said, the rims are your limiting factor. Even with the E rated tires that go above the stock rating, the rims are still 3195 (and some aftermarket are lower)... If you need more than stock weight rating you need 19. 5" rims.

I have been searching for rim/wheel weight ratings for about a month now...

I have the stock forged aluminum rims... are they also rated at 3195?

Can you tell me where to look to find the rating?

TIA

There is nothing on the rims that states capacity, but I would presume its just 3195 (have researched it quite a bit, and thats all I can find). . In fact dually rims are only 2600 lb/ea

... the 265 stock size dura grapplers are even higher...

Can you provide info on this higher rated stock size tire of which you mention? I have only found the highest Load Index tire in a 265 of only 121.
