I purchased Foose 20" wheels 8.5 x 20 & 10 x 20 for
my 2006 Mustang GT convetible.
I was thinking of Toyo Proxes ST 255/40/20 on front
and 295/40/20 for the rears. Do you see any clearance
issues or fit problems.
Opinions or alternative options please.

 

I would think you should be alright with that setup. My proxy 4's are lound on the street I hope the st's are quietier for you.

 

The best purchase and tire set-up I ever had, you won't be disappointed.

No rubbing, not loud, good tread, and equals out the space in the back.

and they look good too!

 

+1.....

 

nice looking cars gents

 

Wardog,
I stopped by local tire shop and asked about the Proxes ST tire and was told it was for a light duty truck.
My car is supercharged and was told they would easily break loose, are these tires still ok for our Mustangs?
P.S. I'm putting them on the same car as yours (sure looks good)
Thanks
