I am currently running 325/60/18 (33.4 x 12.8) Mud terrains. I am thinking of going back to a 32-33 all terrain tire to improve handling and gas mileage. Do you think I will see a dramatic change in handling and gas mileage by doing this? Is is worth spending the money?

 

I'm wondering the same thing.

 

Your mileage will improve a little with the AT and a little more by cutting the width to say 11.5 or so. The ride will also improve and the noise level too. But I am not sure just how much.

 

wow....and I wish my KM2s made more noise ....love they way the KM2s handle, better than most ATs I've ever used in my life. I still get 16mpg in the city with 35s.

 

I have the ProComp Xtreme A/T and think they work great both on road
and off road.

 

Is that 16mpg with engine mods? I get around 14 city with the engine stock, 17-18 hwy with a good tailwind.

 

you may notice a slight improvement with MPG but not much. I remember reading in one of the 4wd mags about mileage differences between an AT and MT in the same size. If I remember correctly, there was about 1/2 to 1 mpg difference, which really isn't that much.

So...at 15k miles/ year and 16mpg, that's 937 gallons/year. At $3.50/gallon, that's $3,279.

Say you change to AT's and gain 0.75 mpg, thats 895 gallons at $3,132, assuimg you actually gain 0.75 mpg.

That equals a savings of $147 a year (again, provided you actually see that gain and drive 15k miles/year)

So...it would take 4+ years to off set the cost of buying new ATs. By that time they are worn out and the whole thing is a wash.

Here's what you can do, send me your tiresand rims, and I'll send you mine. It won't cost you a dime and you will notice the improvement and savings imediately.

 

wow nice one CJ7, well put. instead of all terrains i will get 33" KM2's...eventually

 

Thanks CJ7nvrstk you've convinced me to stop being a little bi*@*h and keep these.

 

Damn! Was hoping for the trade.



Enjoy your MTs.

BTW, will be goin with MTs on my next tire purchase.
