Difference between FWD and RWD Wheels

I was at Sears today to see if they had any 18" rims with the 5x108 pattern. They had a couple they could order but said that they could not install or warranty them or the tires because there FWD rims on a RWD car. This didnt make any sense to me? It would seem there would be no difference. Was this guy just a douche and have no idea what hes talking about or am I wrong in thinking theres no difference?

The difference is in the back spacing of the rim.

sousa is correct that the backspacing/offset is usually different on wrong-wheel drive. However the backspacing on our wheels on our cars are more like a FWD setup. Either way, the guy at sears is an idiot, and you don't want someone like that working on your car, so you should go somewhere else.

You know I have heard that same BS in the past also about how you can't put a RWD wheel on a T-Bird. Been a long time though.

I can't wait to run into the next person to tell me that....LOL

I ran American Racing Avenger 16x7 wheels on my first 96 bird ten years ago...you guessed it, they are FWD wheels, commonly seen on honda civics...although I've seen them on mustangs and birds and cougars from time to time...I scratch my head in amazement that I thought those where nice looking wheels on a bird...

I guess they're not that bad...I wouldn't run them ever again, though.

When Ford designed our suspensions, they knew that longer control arms are better. So to get the longer arms to fit, they went with a wider (FWD) offset wheel. And to make sure people didn't put Mustang wheels on which would adversely affect handling, they used the 5 x 108 spacing that was only used on existing FWD cars (Taurus, Windstar, etc.). Anyway, just some history.....

....man, I know too much of this stuff.

I went to Tire Barn today and heard the same thing. It's getting really annoying! I would really like to get my rims and tires together and have a warranty, road hazard, lifetime balance and rotate.

I've already picked out my rims: http://www.wheelwarehouse.com/p-4166...-new-2010.aspx

Just finding a dealer that will put them on close enough to have the lifetime balance and rotation. Ugh!

If you feel like driving to Kokomo,IN

Discount tire will do them and indy tire will also. Or you can go to a mom and pop have them put the tires on and have tire barn balance them. I;ve had to do that several times in the past.

Why not just order the tires and wheels you want and tell them it's for a taurus. Have the shop mount and balance them and just take them home and put them on yourself. They wont know what you are really putting it on. If a tire failes and you need to use the warranty work, just take it in off the car. They wont know that it didnt come off of a taurus. Im sure the warranty isnt going to be voided because you brought the wheel in off of the car.

Because I want the lifetime balance and rotate. Well worth it to me. ITs a pain in the ass to remove 4 tires, haul them down to wherever let them balance and put back on without a lift and a truck, compressor and airtools.

Tell them the stock rims have FWD offset and they need to change/update their info to get with the times. It should be no difference if you get tires for stockers on not, as long as they fit properly

You generally get those mentioned services when you purchase tires from some chain stores. I dont see why you cant get your wheels then go into the tire shop and have them lace you up and recieve said services. If they have a problem with plus sizing tires for your vehicle then apparently they dont know what they are doing so simply move on.

Seems normal to expect to not need the tire balanced before it expires however its not rare for this to be needed maybe once during the tires life. I think alot of this has to do with either throwing a weight, poor wear or losing the balanced position of the tire on the wheel during a flat repair, etc...Tire rotation is plain simple enough to do in the driveway but deff worth something as a free service I suppose.

the whole fwd/rwd wheel thing is laughable. Sears?? There has to be a better place to get tire service than Sears, Walmart, Costco, Home Depot, Ace Hardware, Outback Steakhouse, Macy's....You get the idea.
