18''s or 20's anyone?

Wondering what wheel/tire combos people are running on the pro touring cars? What size? What offset? ect..
Need some advice!
Thanks!

Not my Buick, but on my Camaro which is a mix of pro-tour and pro-street I'm running 17's. However 18's seems to be the go for most people.

 

18s are a good looking size,..but 17s are the ticket for ride quality,..and tire and wheel options

 

245/40/18 front 305/35/20 rear that are the ones I got from a member here. 18’s slid right in, the 20’s bolted on but will require some slight trimming so they won’t rub.

 

18x9 with a 275/35/18 up front. No modifications to fit (had to remove top inner fender bolt)
18x11 with a 315/35/18 in the rear. I had to trip the inner wheel lip and wheel well mounding, and bash in the inner wheel well to sit flush with the frame.

 

Im very happy with my 17's. great performance and ride quality.

 

18 x 11 rear with 295/40, 1/4" offset. 17 x 8 front with 245/50, 1/4" offset

 

17 on my Pontiac rides nice

 

18x8 and 18x9 on my 72 skylark 255-40 and 275-40
lowered 1.5in, clears everything!

 

go back a page and you will see the wheel & tire thread. There should be alot of info including mine

 

17x7 with 17x8.00 tires up front
17x9 with 275/50 17 drag radials in the rear.
Car is lowered 1 inch front and back handles like a slot car with no issues what so ever.

 

18s and 20s
235/40/18
275/40/20

 

Oh I guess I can add this weekend pics 17inch
