$$I want some large tires and maybe lift my car up higherhow much do you think it will cost me? got any great sites selling Jeep Wrangler tires?It‘s a 1995 Jeep Wrangler YJ
Trust me when I say this. Do not put the tires before the lift because they will look very small. The Jeep Wrangler Rubicons come with 31 inch tires and you might already have 31 inch. Plus you will be 3 inches higher so 31 is WAY to small. The perfect size would be 33 inches tall and 12.5 inches wide. But just incase thats do big do not go any smaller that 32 inches tall and 11.5 inches wide. Go to the Jeep website and look at the Rubicon and thats 31 inch tires. You can also google search for a Jeep with a 3 inch lift and go by that.
Big tires mean your gear ratio in your diffs will change. If you have a 3.55:1 diff gears with 27 tires that will go down drastically as the diameter of your wheels and tires increase. The result is like changing the diff gears to 2.73:1 (just a example). This means that your engine will turn at a lower RPM. It will be harder for the engine to get your Jeep moving from a dead stop, and hills and over passes will be more difficult for the engine to get over, you may loose speed going up the incline, and I'm talking about on the freeway not just on the trail. It will require that you down shift to keep your RPMs up. So the COST is more than the lift kit, the wheels and tires. There is the additional cost of new ring and pinion (times 2) for the front and rear differentials. Replacing the ring and pinions requires exact measurements otherwise they will fail. Two sets of 4.56:1 ring and pinion sets with master rebuild kits will run over $500. Most shops charge about $350 to $500 a differential to install the gears. So changing the gearing of your diffs alone can be over $1000. Yes you can get by with your OEM diff gears, but your Jeep will be sluggish and your gas mileage will suffer.
