Bfg 31-10.50-15 or 30-9.50-15

I know this has been beat to death. I've done plenty of searches, they rub, they don't rub, they rub on factory rims, they don't rub on aftermarket wheels, need a 1" lift, need different fenders etc. I am ready to bite the bullet and buy some bfg ko a/t. I will never be off road. I have the stock rims should I go with the 31-10.50 or the 30-9.50? Thanks.

Street size for street use.

Nothing is wrong with a 235 whatever 15 just want a more aggressive look. I know I can get something wider with a greater overall diameter.

So the 31 10.50s rub everywhere or just when turning?

I don't know anything about how your jeep has aged over the years other than what is in your profile. Every old jeep ages differently. Why not just spend money on a body lift to ensure it'll fit?

Sooo
This is all show and no go?

Then go with 35s. You won't have to worry about breaking anything in the parking lots and if you lose some turning radius so what, No trees to get around on the street, and nothing looks as aggressive as big honking tires.

Yes all show... It's a 4 banger. I know 35s won't fit. If I wanna go I jump in my zo6 not some 20 year old rough riding jeep. I need to know if the 31s will fit without a lift??????

They'll fit and they'll rub. If you want to get rid of the rough idle, buy a throttle body gasket and a can of carb cleaner. Use the whole can on the TB once it's removed. reinstall with the new gasket and your idle should be smooth. $4 tune up.

Rough riding not rough idle. It actually idles very well. Seems to be very well maintained. Will the 31s rub just going straight, turning or what? I am new and don't know the ins ands outs of these yjs. Thanks

I'm not sure what else I can add...you've already gotten alot of good info.

I'd recommend a max of 30", but you will probably have to put a washer under your steering stops, so you don't rub the swaybar.

If you want to install 31s, then do it, but be prepared to add a body lift, as recommended above.

Do 235s I had them on my jeep when it was stock and didn't have rub problems. They're about 29" tall and normal width.

If you're set on both of your choices then go with the 30s
