18x9 Tire Size Advice +38mm rim
I have 18x9 RPM 505's on order with a +38mm offset.
Going on wife's 99' Z-28 that is lowered maybe 1" using the lower Koni shock mount and rear spring rubber isolators removed.
I can get a sweet deal on some 275/40/18 but concerned they are too tall/wide for the front. Plus a 40 series may ride a little better and fill the wheel well more, being 1" taller OD than stock.
Looks like some have run a 275/40/18 and some run a 275/35/18. Should I go with even a smaller width in a 35 series?

I run 275/35/18 up front on a 18 x 9 inch wheel w/+45 offset,
and 275/40/18s in the rear w/same wheels as front.
FYI, a 275 is not too wide.

Thanks All. Xsta Z 28, please keep up the good work. Looks like you have been answering all the crazy "does it fit" questions for a long time. Invaluable service IMO.
Adam post some pics when you can. Striker I will try to do the same in short order.
