Upsize Tires on 2024 Gladiator Sport S

[bd100]

For my Sport S I currently have 265/70R17 all-terrain tires. Same diameter as the 247/75R17, so no change of speedometer, total gearing, pulling power, off the line, towing, etc. But they are 9 inches across the tread instead of 7, and it's an all-terrain tread pattern, and they are LT-E tires, all of which makes for a stiffer ride, great sporty handling, unchanged towing, minor loss in fuel efficiency, quiet on the pavement, durable offroad, and excellent for carving 55mph mountain roads with 20mph switchback curves. Crawled a bunch of Colorado and Moab rocks, no punctures. But no lift either, so I added skid plates and stay off the really nasty trails.

I chose this route for now because I have to travel cross country to get anywhere interesting, and I have my family with me so I cannot take extreme trails. We have to be able to get back home again. So they are compromise tires, good for suburbia and highway and able to survive offroad as long as I don't choose the crazy trails.

Mine happen to be Cooper Discoverer LT-E, but any all-terrain with 3-peak symbol and a high silica tread compound should be fine. I don't know first hand but some people claim that all-terrain tread is good for sand.

If you want to go taller, a 34" narrow tire may work.

Have you thought about a set of rubicon or Mojave take offs? I’ve seen some good deals on marketplace for a whole wheel and tire setup and it would be a good way to move up in size.

I haven’t made a definite decision yet but when I get my Mojave I may have a set of take off’s up for sale.

?

I put Falken Rubitrek 285-70r17s on my sport s. I did up the wheels to a 8.5 inch wide, but not necessary…

We have recently gotten a fair amount of snow, and the Rubiteks have done great! There is some road noise, but it really isn’t that bad. These have a similar tread pattern to the wild peak at3s, but are quieter (according to Falken).

I do have max tow, so 4.10 gearing…

I was very happy with Ridge grappler 255/75. More than. An inch taller than stock but not too much wider. On my 2020 sport worked very well

3.73 or 4.10? I recently picked up a 2024 Sport S non-Max Tow (3.73 gears) and am doing research on tire size options. There are tons of threads, but I've noticed that not everyone notes which gears they have.

The stock Dueler H/T's are fine on the highway, but I'm afraid to take this to my local OHV park with them on. Other than that one local park, I have to drive at least 3 hours one way (or even out of state) on the highway to anywhere else for off-road. So I'm trying to find an A/T tire that is good off-road, but also decent on the highway/around town, and doesn't absolutely obliterate gas mileage/performance. I don't tow, so that's not a concern. If I can get a slight size increase to gain a fraction of an inch ground clearance at the diffs, that wouldn't be the worst thing either

Your post was the first I noticed mentioning 255/75, but I've also researched 275/70, 285/70 and 285/75 - the latter (33") may be too big for 3.73's? I've definitely fallen down the rabbit hole researching re-gearing, lifts, and other mods, but I have to try to temper that itch. The whole point of getting a Sport S was to have something moderately capable without spending a fortune, knowing that I'm not towing and likely not rock crawling in Moab or anything extreme.

If you care about mpg 275 is going to be too much rolling resistance. I had 4.10. It's the width and weight that hurts mpg. The ridge grapplers were great off road in Fl. I can't speak to rock climbing
The highway ride was almost as good as the stock AT ( i never had the base tires)

Thanks, I'm definitely going to consider the 255's, then.

OP: I've been debating this ever since I purchased my tires (Falken At3w's SL 285/70/17). I'm still running them on 3.73 gearing without any issues, but not sure if I I would go with the AT4w's as they are very heavy.

I'd like to increase tire size. 34? 35? Some people say it's fine on 3.73s. Others say it's horrible. It's the main reasons I haven't upgraded yet.
