Wheel fitment question

[flynz]

just picked up a set of weld rts s77 finally but just noticed in ad it says 17x9.5 with 6.5 backspace 32mm offset... I think our cars call for 7.0 b/s and 42mm. Anyone running this set up with pics available or know if it will clear okay

 

[Catmonkey]

That backspacing boils down to a 25mm offset. I think you'll have problems.

@Catmonkey For reference they’re coming from a 2015-2017 s550 car. The picture sent shows them mounted on the rear of an s550 at the gas station. I’m thinking he’s confused about the specs and these are the 8.0 b/s and 61mm offset I keep seeing on every vendors site for the s550 rear wheels.

 

[Catmonkey]

It would have to be a pretty narrow tire to fit under the fender with the 6.5" backspace. 8" backspacing for a 10" width would probably be ideal.

@50stangpower can you chime in on this please. Saw your car and have been in love with set up since then

Mine are sitting in my garage so I will look tonight. I went with 17x10.5 but don't remember the b.s. I'll measure in a bit

To the top, proper wheel specs put in first post 17x9.5 6.5b/s 32mm offset will post pics as long as they fit. Will be running 305/45/17 MT super street s/s

 

[Catmonkey]

I don't see it tucking under the outer fender. By my calculations, it'll be a bit beyond an inch outside the fender if the specs you posted are correct.

@Catmonkey we will see... for the price I can always resell and get money back from an S550 owner

The is the full outter edge of the wheel. This is a 17x10.5

This is the lower lip (or the bead) 17x10.5

Also food for thought. I had a rock get stock in between my wheel and rear caliper. scarred the inner barrel up pretty good. 17" is a tight fit, or I just have bad luck.

@50stangpower On the 18x10.5 race stars I just removed for these it was a scary close fit too, couldn’t put more than 4 business cards between wheel and caliper. I’m hoping with the 6.5 backspace it actually pushes it out just a little. I like how the rear wheel on your car sits and tire is out just a tad, again your car looks amazing, one of the reasons I bought a GT500 in all honesty would want to happen to sell your wheel set up would you?

 

[50stangpower]

Thanks for the compliment. The only way the wheels are going is if I sell the car. The Tires change the entire feeling of the car. I am hoping I will actually drive and enjoy it more this coming year. I am so paranoid about keeping it clean that I barely drive it and it has lost some of its appeal. I will usually just hop in my LS YJ and cruise anywhere with the top off.

@50stangpower what front tires did you go with? size and make

 

[50stangpower]

Mickey Thompson 26" radial. The only one they make.
