looking at a set of 17s for 79 620

[BlackBird620]

OK so I went into a tire and rim shop out here and found a set of 17s that I had my buddy Photoshop onto the 620 I plan on running 215/45s up front and 235/50s in the rear but I'm not sure of the offset I need on the rims the rims only have 3 different offsets from the dealer -22,0,+22 can anyone shed some light on this for me since I know nothing about wheels

Well at last some common sense. Find out what fits first. Most just fall in love with them, then buy them then try to make them fit and start crying.

Here's one that shows the tires too.

You might also measure one of your wheels to get a good real work comparison.

i can get you a decent set of 17s from japan starting at about $600 shipped

 

17x8 0 offset is about perfect. im running 8.5 -10s on my 73 620

here are how my 16x8.5 negative 10 offset look on my truck

 

as for tires im running 225/45 up front and

245/45 on the rear. 

 

check out this site to compare and contrast

in comparison, my 225/45s are obviously 10mm wider than your 215s, 

and only 'shorter' by .7" (my 23.9 circumference vs your 24.6)

which is only .35" in radius. ive lowered my front close to 4 inches 

so you def got room up front. 

 

in the rear again im obviously 10mm wider in the tire, but youre now

1.7" taller. (24.6 vs 26.3) or .85" in radius. 

i got 3" blocks on the rear and im good, so i think youll be good to

 

i will add that my rear tires do scrape, even after some modest hammering

on the inner lip of the rear fenders. but again im 10mm wider than you....

 

 

what wheel width are you thinkin?
