I just finished up my 3" lift and am looking for the right size Toyo to stick under it. I know I can fit a 35 - but I'd like something a little smaller but wider. So 33x12.5x18 or is there something else that gets me a little bigger but just as wide? I'm sticking with the Toyo Open country M/T for sure. Thx..

that's all the sizes they make, just click on the sizes and specs tab.

 

I asked this same question a few weeks ago and everyone told me to get 35's. Ive now decided on 35's. Many people who get 33's are not happy and wish they had 35's, but it is rarely the other way around. I decided on Goodyear Duratracs...They are sort of a A/T and M/T hybrid, but rated well for snow, ice, water, mud...etc. I went to a local goodyear store and they had one on display. They look like really nice tires, I was pleasantly suprised. The size im going with is 315/70/17 which comes out to about 34.4 tall...under load it will be about 34 Maybe this is a good alternative for ya

 

Here are the Toyo Open Country M/T's in a 295/70/17, which is just about 33.5x11.5x17.



And here's comparing them to the stock Rubicon tires (with about 50k mi on them)

 

That's what I've got....you're going to love them!

Go 35's with that 3" lift.

 

I wouldn't do 18" rims with 35s. The rule of thumb is to have your rim about half the size of your tire--that gives plenty of sidewall to protect the rim when off-roading at low tire pressures (I run at 12-15 PSI; some run even lower). On top of that, most tires are an inch or so smaller in actual diameter than what they are rated--my 33s measure out at 31-1/4" when mounted under load (that number gives me an exactly correct speedometer).

33s versus 35s: Yes, there are some folks who decide that 33s were too small for them--not as many as those who went straight to 35s would have you believe. And, there are many of us currently running 33s and happy to be so.

I off-road on some pretty tough trails in Disney and Moab and keep up with folks on 35s and even 37s. And, during two trips to Moab my partner had to stop for gas twice as often as me because of his 35s tearing up his gas mileage. 33s took me from 20.5 MPG measured over about 15K of varied miles, to 16.0 or so MPG measured over many tens of thousands of miles--and worse gas mileage is huge negative for what I enjoy: Off-roading on multi-night trips where the only support I have is what I carry. 35 inch tire MPG performance is certainly a major deterrent for me to ever upgrade (I currently have about 66K miles on my Jeep).

Also, on a recent trip back from Disney, I had to slow down in a small caravan of Jeeps because the one on 35s could not keep up with us on the turnpike: At 75 MPH. We had to back off to 70 MPH.

Finally: Reliability. 35 inch tires are heavier, placing that much more stress on vehicle components.

I will give 35s one thing: I think on the four doors they look better than 33s. But, I'm not so much in this for looks as for performance. I will need tires early next year and may decide to upgrade to 35s, but, trust me, it is far from a done deal because of the huge negatives associated with that change.

 

Here's 2½" BB with 33's... wish it was just a bit more (so 35's would be good). Make sure though, you don't have to change your spare tire rack as it may weight too much on the door!
