Which 31"s or 32"s on a 4 Banger?

I'm currently running el cheapo 30"s on my '99 4 banger stick. It's my daily driver, which means I'm 90% on road. I DO want, in order of importance, durability/tread life, wet traction, off-road capability, won't TOTALLY sap my limited 4 banger power, and reasonable value.

Basically, I'm down to either 32" OR 31" BFGs (the A/Ts), or the 31" Firestone Destination A/Ts.

Opine away!

I've got 31 mud kings on mine now, I did not notice a huge difference going from stock, to 30's , to 31's. When my 31's wear out I am putting 32" TSL's on.

I have the 32" BFG AT on my 99 4 banger. I went up from a 31" tire and didn't notice much difference. This is my daily driver and they are nice and quiet and ride smooth. I had them on a previous Jeep and they wear really well too.

Thanks, Owen_TJ! I was worried about the 4-bangers ability to cope with 32"s, but I think I'm going to be ok.

Now, I'm guessing I'm going to need a small lift. I was looking at the rough country 2.5". Jeep TJ Suspension Lift . Seems like it would be enough.

I was running 31" M/T then switched to 32" BFG A/T...Not the most power, but not weak either...I have a 2" BB from Zone. Good cheap lift with new shocks
Before...w/31's

After...w/32's

Currently have 31s on my 03 2.4l, with a zone 3'' lift and I have no complaints. I want to run 33s, but I don't want to re-gear. I think 32s will be my choice. The 4cyls have 4.11 gearing so I think Ill be fine, or I at least hope I will be.

I personally like the gearing ratio with the 4cyl and 31's. For a 90% DD, I really don't see the need to go to 32's other than the looks of a bigger tire.

Years ago I had 32's and I remember having a little more clutch slippage getting things movin.

Sorry it took me so long to post again haha...kinda slipped my mind!

Anyway, here is my 99 2.5L with 3" zone suspension lift (strongly recommended) and Falken Rocky Mountain ATS's in 32x11.5x15

After...
