how wide of a back tire?

Just depends on what you are after. If you look at the specs on any tire manufacturer's website or even www.tirerack.com, they all say no wider than a 255 on a 17x8 inch rim. If you want something wider, I would look at upgrading to 9 inch or wider rims in the rear. While you may be able to fit something wider on the stock rim as some are bound to suggest, the tire will not perform as the manufacturer designed it to.
 
[QUOTE='03GTinFLA]I like the discussions on these topics. I run 275's, no problems. So now you have the manufacturer's recommended size, discounttire.com's recommended size and the average joe's recommended size. All different.

Let us know what you choose.



go big :nice:[/QUOTE]
I know. Pretty entertaining, huh? I know who I would trust out of the three sources.

So he was asking how wide of a tire will fit. I'm pretty sure 275's are as wide as can actually fit on the stockers. Now as far as Ford's recommendations, that's a different story, and good to know. My point is, Ford probably doesn't recommend nitrous or 75mm TB's or gas pedal spacers, but it can be done and doesn't mean that your car will explode. Same with 275's, doesn't mean your tires are gonna fall off.
BTW I do plan on doing the gas pedal mod and i bought a predator after checking out your posts and car-domain site, so i'm not trying to say not to listen to your advice. Just trying to confuse the kid with different opinions. :D

The recommendations aren't Ford's, they are from the people who manufacture the tires. Go to any tire manufacturer's web site and look for yourself. Tires are not a one size fits all deal. There is a reason they make them in different sizes. There is also a reason they make the size recommendations. Your logic that nothing has happened to you so it must be OK is troubling. It is one thing to do it on your own car but, to push others who are not sure for themselves to do it is what I have a real problem with.

Here are a couple of examples.

Nitto which most will agree run narrow recommend no wider than 255 on a 17x8.

BFGoodrich also recommends no wider than a 255 on a 17x8.

Fact is pretty much every tire manufacturer is gonna say the same thing.

Which rims do you have? You can get almost anything out there. If you can't find your rims in a 17x10 you could have them widened. There are a lot of companies that do it. It would probably be less expensive though to buy a new set. I am kind of partial to the 17x9/17x10.5 Bullitt deep dish myself.
