    40x15.5x20 Toyo going smaller what do you guys like now?

    Bought a used JK around 3 years ago running 4.88's and the big Toyo MT's. Its been my daily driver and its time to go smaller for the gamut of reasons. Should I ditch the 20X12 inch wheels and go with a more practical 17 or 18" wheel? I live down south, so rocks aren't a primary play time and I haven't had time to do much of anything other that travel and visit my ailing father out of town, so Im spending a good deal of time on the interstate. I don't want to get a tire that is too pavement worthy as I don't want to make the Jeep worthless when Im hitting the bottoms comes Duck season. Looking at the Toyo and the Nitto all terrain as well as the Cooper Stt. I know the Stt is a better mud tire, but Im really considering something a little less aggressive.

    Any info is appreciated

    Most are happy with 37x12.5 or 13.5 R17. If you're not built for 40's that can be problematic as well. Being geared at 4.88's a 37 will get you back close to stock tire and gear ratio. A 35 may be a bit small causing you to run higher in the RPM range. I'd ditch the 20's and go with a 17x8 or 9".. It'll also open up your tire options more than an 18" will. Being that you said you are spending a lot of time on the pavement a good AT will work well for you. The 3 brands you're looking at provide excellent choices. If you haven't done so maybe give BFG a look too. I'm running the KM2's and they have held up well and have close to 40k on them. The new KM3's look good for a mud and the KO2's are a proven AT. Hope this helps.

    Toyo open country r/t looks like a nice tire.

    Or the Nitto Ridge Grappler.

    For your stated needs, Iíd go with a 37x12.50 in a 17Ē wheel. .

    Thanks for the info. My lease came up yesterday on my grocery getter, so its time to make a change as I wont be picking up another vehicle until this fall, even though I spend the majority of time in the JK. The Jeep is set up good with the long arms and the double D, but is missing the most important which is tons and is its the textbook definition of a mall crawler. I hate to buy wheels and then in a year or two upgrade to some decent axles and be stuck with 5x5 lugs. I guess the smartest thing to do is continue to run the 20's for now and just decide on which 37" tire to run. If I do a slicker tire I think the Toyo RT is what I will go with, but I am hesitant just for the slop around here and its leading me to do another set of the Toyo MT's or the STT's. Maybe some guys will chime in on the STT vs Toyo MT comparison that may have run both.

    thanks again Jesse

    I have the Nitto Ridge Grapplers on my truck. They have the typical aggressive style Nitto sidewall but have a AT tread. I really like them.

    Is there much of a noise difference between the Toyo and STT once there are worn a bit?

    That's a great option! How about wear? I have been impressed with the Toyo wearing very good and lasting long, but I wouldn't mind shedding a few pounds of mass too.

ďwayoflifeĒ is a moniker that Iíve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
