FIRST TIME JEEP BUYER

[MiklScott108]

With the stated tire dilemma I need some assistance. My brain for some reason can’t grasp what tire size to get. Lol. It came with Vision 353 Turbine 17”x8.5” w/ -6mm offset. Obviously the offset doesn’t play too much of a factor into what tires I can get (correct me if I’m wrong) but what’s throwing my head for a loop is looking for tires it’s all metric. It’s has LT245/75R17 and they look like they aren’t wide enough for the wheel they are on. So if anyone can point me in the direction I need to go that would be swell!

My Mojave came with 285/70r17 Falken Wildpeaks AT/3s on it. Quite a good ride to them, on or off road.

Those are street tires and won't have the extra width

Okay, so when they say the width of a tire is say 10" or 285mm on the Falken Wildpeak A/T3's stated above, even though my wheel is 8.5" wide it will work? Or do I then risk if I ever (not any time soon) air down to get through a rough area risk popping a bead because the tire is wider than the wheel? Sorry, Im just trying to understand this cause it's a whole new world I'm delving into. Lol.

So, your stock wheel size on that Sport S is 17 inch by 7.5. If those wheels you have on there are slightly wider than that at 8, then putting the 285 70r17 wildpeaks on there should fit fine.

Certain widths of tires dont fit on wheels smaller than the tire, but wheels are normally a smaller width than the tire, again, within certain ranges.

So that 285 70r17 is considered a 33" tire. Its actually around 32.4, but no need to get that deep into the weeds.
The wheel is 17x7.5

That is the recommended tire for that size on a Mojave. I know for a fact that wheel will fit up to a 35" tire, which comes in at roughly 315 70r17. I wouldn't push it above that 35" without getting larger (wider) 17 inch wheels.

Discussions over tire/wheel size and "bestness" on Jeeps vs. conditions is quite literally a tale as old as time.

If you are going to mainly using this truck for road travel, with some light offroad for camping access and such, you really dont NEED anything larger than the 33's. Completely my opinion.

Beyond this, you start getting into the arguments about skinny tires vs wide tires and such. Keep it as simple as possible. Do your research into tires that match what you are going to be using it for.

That being said, those street tires you do currently have on the Jeep are going to have little to no grip even in light mud conditions.

Quadratec, for all their faults has a decent page to research some of this stuff on. The information is about a year or two out of date, but is a good jumping off point.

Good luck.

Also, a good rule of thumb (roughly) for airing down your tires without beadlocks is never get them lower than your wheel size. Until beadlocks and you getting a better feel for how your vehicle rides, I would keep them at 20lbs or more.

The tire will tell you what width range wheels it should be used with.

For 8.5" wide wheels like you have, you can run 12.50-13.50 wide tires.

The tire being wider than the wheel is not an issue when it comes to airing down. In fact, it's preferred the tire is wider than the wheel. Having the wheel narrower makes the tire hold better.

Okay, thank you! That’s more the layman’s terms I’m looking for. Lol. And yes, the street tires need to go. I’ll probably run them for the summer just because we have a newborn so we won’t be doing anything other than back roading paved roads. I’d like to get something better before next winter though that can give me a little extra grip in the snow we get periodically but also give us the freedom to start doing some dirt and gravel road trips when the following season comes.

Again, I was more than pleasantly shocked by the Wildpeak AT/3s. I thought for certain I would need Blizzaks or Hakkapeliittas for the winter in Anchorage, but I was very wrong.

They worked as well on Anchorage deep street snow and icy roads as I could have ever asked for. Very likely going to be buying another set when the time comes, but in a 35" .

I've repeated this on other threads but I can't vouch for the Wildpeak AT/3s in snow (not here in South Florida), but they have been more than capable in sand and mud here. I think Jeep chose an overall good tire for my JTR (the stock 33") that seems very capable for what many of us ask them to do. I'm not exactly sure if I need to go with a much higher tire in the future when my near-70 year old legs aren't getting longer.

But with my Apex 12000 on the front, I'm pretty comfortable with the places I go, even during rainy season. At least in my case, I'm not sure another inch in height ((35-33)/2) would really matter than much.
