    Hey guys,

    I'm looking at picking up some new (to me) rims for my car. They're used so it's hard to ask the guy if I can drive to his place an hour away and bring my jack to see if they will fit on my car before I start negotiations. Hopefully, someone could give me an educated guess...

    The wheels (Pictured below)
    Front: 19 x 9.5 ET 18 (About 5.96?)
    Rear: 19 x 11 ET 37 (About 7.46?)
    I used this site for the calculation (https://www.customwheeloffset.com/tire-wheel-backspacing-offset-calculators)

    From other information I've found on Chevelle sites, these are the measurements that will fit correctly are...

    Front: 9.5"__5.5 BS (5.96-5.5 = .46 outward)
    Rear: 11"____6.6 BS (7.46-6.6 = .86 outward)

    If it was in I could add a wheel spacer and be fine but because they're positive going outwards away from the hub there's not much I can do but hope that it clears the fender & 1/4.

    I would bring my car and test fit them personally

    I think a 9" front @ 5 1/2 backset would be ok but the rear 10" even @ 6 1/4 backset would be pushing it. To do more I think you would need to roll the quarters and clearance you front.

    I run a 18 x 10 with a 6 inch BS on front with 285-35-18 and a 18 x 11 with 6 inch BS on the back with a 295-40-18 (will go to a 315 40 18) though. You will need a spacer on the back, Front depends on what mods you have done. i have the tall spindle conversion that kicks out the spindle 3/8" so 6 inch BS was needed (it is real tight turning the wheel lock to lock with clearance to the A-arms). 5.5 BS would be ideal for a 10 inch wide in front if stock offset on the spindle. you really need to test fit with a tire and have the suspension loaded. There are a lot of variables involved (fender clearance to wheels (and that changes with caster, etc) that get involved running bigger tires. Since these are 19s you will probably be ok in the front clearing the a-arms, but tires may hit the sway bar. The back will rub on the inner fender/frame without spacer.
