[drummerboi]

Ok I'm a new owner of a beautiful black 03 300a I've had it about 3 weeks now and loving it more more as each day. I have ? About tire size, I think I read somewhere on here that the rear tire is suppose to be bigger but all mine are the same size, will this hurt anything? Also my air ride comes on sometimes twice in one ride I'm a big guy so I was thinking it was going out. My ? Is if I let it feel up with air and turn air ride off will it stay at the height or go back down? I don't like my rear end low.. Thanks you guys have helped me so much thanks!!

Question #1 --- You say that you have a 2003 300A MM. That means that you don't (or probably don't) have traction control. So, you can run the same size tires all around with no problem.

Question #2 --- Sounds like you may have an air leak in the rear air-ride suspension system if the compressor is kicking on frequently while in operation. Turning off the compressor will only aggravate the situation by letting the rear end drop down without refilling the bags. You might want to get this checked out to see why its not holding air.

FWIW -- mine will drop down overnight or if it sits for a long time. You may also notice the compressor kick on if you add a load to the trunk or add a few passengers. This is normal and the compressor activates to compensate for the larger load.

BTW --- your MM will let you know pretty quickly if you have traction control and have mismatched tire sizes or someone decided to rotate your front tires to the rear. You won't get 2 blocks from the shop before you notice that something is amiss.

Your right no traction control.. So I guess I'm good with the tires.. So if I don't have the traction control button does that mean I don't have it?

Mine kicks in just about everytime I get in and out.. Like I said I'm a big guy do that might be why..

No T/C button. No traction control.

They aren't the same thing. All Marauders have Trac-Lock, but only '03 300Bs and '04s have traction control.
