If tire sizes in 17 inch diameters are getting hard to find for wider profiles, does it now make sense to get 18 inch wheels vs 17 inch wheels if starting fresh? Or, does it make sense to just get slightly narrower 17 inch wheels and go with 17's?

For example go with 8.5 or 9*17 fronts and 10*17 rears, or better to go with 8.5*18 front and 10.5 or 11*18 rears?

Do 18's really mess up the overall suspension/damping/rebound/steering response vs 17's or 16's?

Hope this helps. After debating which offsets, sizes, shapes, colors, ect. , I went with RUF 9x17 front and 10 x17 rears, on both cars. I do have a spacer on the passenger side on both, Rim is strong and easy to clean. I do have to shorten the lug bolts on the rear, if i want to use the original bolts. The spacer is a 1/4 inch , roughly 26mm. Tire rack fo have plenty of rubber for 17s. My tire sizes are
235/40/r17
315/35/r17
Toyo 888

315 for of 10 " in the back it is far too much, normally the maximum for of 10 " is 275.

Same here on tire sizes.

Funny how my passenger side also needs about 20mm spacer rear if driver side is spot on. There must have been a drunk welder on passenger side back in Germany.

Is it common to need spacers on one side to achieve equal distances from the wheel arches?

Yes, ;-)

And for those who want to know the possibilities about the size of tire to be installed(settled) with the various sizes of wheel rim.

As far as specs for wheels (offset, etc) maybe check out our wheel tech article for some additional input: Wheel Fitment and Spacing Guide - Pelican Parts.

im surprise by the minimum width on that chart. there are production cars that have narrow tires than that list.

Yes, it was maybe because there were no sizes of tires (in the 80s), RUF on my wheel rims before and back (9 " and 10 ") always put the smallest with regard to(compared with) the picture(board) above, that is 235 and 255.
It was maybe also a question of conformity with regard to the diameter of the back wheel and the calibration of the speedometer.

i think those sizes are perfect for 9 and 10's. its proper on a performance oriented set up.

wider the rim within reason gives a tire quicker response. the reason why many manufacturers dont recommend wider rims on narrower tires today is for warranty and passing the "Car Wash" test in which the rims get easily damage once folks replace oem rim protector type tires with something else.
