first time jeep owner

I am in the process of getting my first jeep. I have found a 1995 jeep Cherokee sport for $500. it needs a motor and tires. I want to use this as my daily driver so I am just going to replace the 4.0 motor with a rebuilt one. I would like to know the best size tire to use for daily use and occasional off roading. everything is stock on the jeep. any information would be greatly appreciated

What is wrong with the motor? If your replace everything on the motor, like harnesses and everything, make sure it's the HO 4.0 instead of the renix. Also stay away from the 00-01 for engines. Head cracking issues is to likely and they have coil packs, distributor is better. If is just the block any will work. Also don't try and swap a WJ or TJ motor in. It's a completely different block that requires some major mods to get it to all work.

For tires at stock height I would go with 235/75/15. Its the biggest tire size that you can fit at stock with no major issues. They are a tad bit bigger than the stock tire from the factory but work great on the XJ.

RENIX (Renault/Bendix) is the fuel injection / engine management system used in XJ Cherokees prior to 1991 (87-90). A 95 would not be Renix to begin with and as long as you stick to 91-95 parts you should be fine (96 went to OBDII). Before you do anything with the engine, check the flex-plate, a loose or cracked flex-plate on a 4.0L I6 will sound almost exactly like a bad rod knock.

HO stands for High-Output but is basically meaningless since every 91 and newer 4.0L I6 is an HO. So they are only "High-Output" in comparison to older Renix engines and it isn't that big of a difference anyway.

It stands for Highly Overrated actually.

Here's a nifty write-up with photos on checking those flexplate bolts.
