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 have a 4 banger on 31īs and drives very good and has good power and mpg im getting 20 mpg on highway and 19 on city (driving very soft but not much)(not like a grandpa) if you can buy a 31 are very good i recomend you the firestone for the mpg and power and bfg at if you whant off road traccion

this is my tire http://www.mueblesamerica.mx/imgs/medium/EUZK00016.jpg is very good but its a mexican tire (im from mexico) drives very well on water mud sand rocks and road very cheap and good tire

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.

So... Firestone Destination 31"s or BFG 31"s or 32"s?

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.

I run a 32x11.5x15 on my 99 as well...

I'm at work at the moment so i'll post a couple pics for you when i get home as well as a longer reply...

but in town driving isnt bad at all, i only hit a couple problems when i go on the hwy and hit an incline...

no regrets doin it though...

My vote for tires: Falken Rocky Mountain ATS's

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

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.

Dextreme 11-09-2011 03:35 PM

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
