I have found a set of rims and tires for sale, here is what it is.
Front 17x8+30mm offset, tires are 235/40/17
Rear 17x9+24mm offset, tires are 275/35/17

Now will this work with rolled fenders in the rear....? Or will I need to downsize the rear tires? Anyone with experience with a similar set up or one of the Gurus please answer. I dont want any "I think that will work" from the crowd who has no experience with the set up or wheel/tire experience.

 

Fronts okay, but there is no way in hell you're going to fit 275's under the stock rear fenders.

If you stuff 255 / 40 / 17 tires on the rears, you should make it, but no way with the 275's.

You can drop the 9.0" width in the back down to +35 easily, but you're running +10mm more than that, which means the 275's are going to contact the fender and no amount of rolling is going to get them to clear unless we're talking about MAJOR fender modification.

Hey thanks for the reply Ted. Ok the place I am getting the wheels from said they can do +45mm offset with the same wheel. Would that be better..? I dont understand what the offset #s mean is the higher the # the more the wheel is pushed out or what..? Well if +45 would bring the wheel in closer maybe I could use some spacers to get it to the right offset. This stuff is pretty confusing to me. Those are my 2 options for the rear wheel offsets. Which one would work best for putting the widest tire on the rear the +24 or the +45? Also if you could tell me what is the biggest tire I can put on with which of those offsets and fender rolling. Any help is greatly appreciated and I hope this thread may help others going through buying a new tire and wheel package.

P.S. I got this idea from TIIaholic on here. He is running stock Mustang GT tires 17x8 but I dont wanna run a 17x8 in the rear. He put 275s on the 17x8. Here is a link to his set up. http://www.cardomain.com/ride/2174792 Anyway if you check back in here ted I would appreciate your recomendation on what rim and tire size I should go with here. If 275s are just outta the question, than I guess so be it. Your help and advice is greatly appreciated. I would like 275s but if I cant do it with just rolling the fender than I will have to look at the 255 or maybe a 265..? Thanks again.

 

you can BARELY fit a 275 wide tire out back on an FC, and thats with a +35 offset wheel. whether its 8.5" or a 9" or 9.5" or a 10", those will all place the 275 in the right spot...
BlackFC ran a 17x10 +35 5zigen with a 275 tire and I dont think he even had to mod the rear fender lip, if anything its just a little bending up of the lip and no movement of the actual fender.

*but once you run 10.5" or wider you will need an offset that is closer to +25 or less just to move it out from the trailing arm.

soloracer has a 17x10 +35 and its REALLY close to the T.A. but it clears.
I run a 17x10+25 and its a few mm from the T.A. and never touches it.
(yes we both run 285 out back under some wider fenders, just letting you know how close those offsets get to the suspension)

 

Ok so with the rear 17x9+25mm I just need to put a 10mm spacer in to put me at +35mm offset and I should be fine? I have seen spacers at Summit Racing I think for not a bad price. Then I suppose just some longer wheel studs to make up for the spacer. Thanks for the info guys I really appreciate it.

 

You're going backwards.
To convert a +35 to a +25, you use a 10mm spacer.
You cannot go backwards - i.e. +25 to a +35.

I see, well thanks for correcting that. Like I said I did not quite understand how that worked. Now I get it. Thanks Again

Ok I managed to find a 17x9 +36mm will that work with a 275 or should I look at 265s? I have seen everyone recommends +35mm but will the 1 mm differeance be to much of a differance?

 

Swany I posted pics of my setup to help you out in the official wheel fitment thread.

 

No, the 1mm difference is not that big of a deal.
